NAILS IN HEALTH AND DISEASE

August 30th, 2009

Introduction:

The nails are present at the end of each finger tip on the dorsal surface.The main function of nail is protection and it also helps for a firm grip for holding articles.It consists of a strong relatively flexible keratinous nail plate originating from the nail matrix. Under the nail plate there is a soft tissue called nail bed.Between the skin and nail plate there is a nail fold or cuticle.Normal healthy nail is slight pink in colour and the surface is convex from side to side.Finger nails grow 1 cm in three months and toe nails take 24 months for the same.

Importance of nails in disease diagnosis:

The colour ,appearance,shape and nature of the nails give some information about the general health and hygiene of a person . Nails are examined as a routine by all doctors to get some clues about underlying diseases.Just looking at nails we can makeout the hygiene of a person.The abnormal nail may be congenital or due to some diseases.The cause for changes in the nail extend from simple reasons to life threatening diseases.Hence the examination by a doctor is essential for diagnosis .Some abnormal findings with probable causes are discussed here for general awareness.

1) Hygiene:-

We can make out an unhygienic nail very easily .Deposition of dirt under the distal end of nail plate can make a chance for ingestion of pathogens while eating.If nail cutting is not done properly it can result in worm troubles in children.When the worms crawl in the anal orifice children will scratch which lodges the ova of worms under the nails and will be taken in while eating.Prominent nail can also complicate a skin disease by habitual scratching.Sharp nails in small kids cause small wounds when they do feet kicking or hand waving.

2) Colour of the nails:-

a) Nails become pale in anaemia.

b) Opaque white discolouration(leuconychia) is seen in chronic renal failure and nephrotic syndrome.

c) Whitening is also seen in hypoalbuminaemia as in cirrhosis and kidney disorders.

d) Drugs like sulpha group,anti malarial and antibiotics ect can produce discolouration in the nails.

e) Fungal infection causes black discolouration.

f) In pseudomonas infection nails become black or green.

g) Nail bed infarction occures in vasculitis especially in SLE and polyarteritis.

h) Red dots are seen in nails due to splinter haemorrhages in subacute bacterial endo carditis, rheumatoid arthritis, trauma, collagen vascular diseases.

i) Blunt injury produces haemorrhage and causes blue/black discolouration.

j) Nails become brown in kidney diseases and in decreased adrenal activity.

k) In wilsons disease blue colour in semicircle appears in the nail.

l) When the blood supply decreases nail become yellow .In jaundice and psoriasis also nail become yellowish.

m) In yellow nail syndrome all nails become yellowish with pleural effusion.

3) Shape of nails:-

a) Clubbing: Here tissues at the base of nails are thickened and the angle between the nail base and the skin is obliterated. The nail becomes more convex and the finger tip becomes bulbous and looks like an end of a drumstick. When the condition becomes worse the nail looks like a parrot beak.

Causes of clubbing:-

Congenital Injuries

Severe chronic cyanosis

Lung diseases like empyema,bronchiactesis,carcinoma of bronchus and pulmonary tuberculosis.
Abdominal diseases like crohn’s disease,polyposis of colon,ulcerative colitis,liver cirrhosis ect…

Heart diseases like fallot’s tetralogy,subacute bacterial endocarditis and ect..

b) Koilonychia:-

Here the nails become concave like a spoon.This condition is seen in iron deficiency anaemia.In this condition the nails become thin,soft and brittle.The normal convexity will be replaced by concavity.

c) Longitudinal ridging is seen in raynaud’s disease.

d) Cuticle becomes ragged in dermatomyositis.

e) Nail fold telangiectasia is a sign in dermatomyositis ,systemic sclerosis and SLE.

4) Structure and consistancy:-

a) Fungal infection of nail causes discolouration,deformity,hypertrophy and abnormal brittleness.

b) Thimble pitting of nail is charecteristic of psoriasis ,acute eczema and alopecia aereata.

c) The inflamation of cuticle or nail fold is called paronychia.

d) Onycholysis is the seperation of nail bed seen in psoriasis,infection and after taking tetracyclines.

e) Destruction of nail is seen in lichen planus,epidermolysis bullosa.

f) Missing nail is seen in nail patella syndrome.It is a hereditary disease.

g) Nails become brittle in raynauds disease and gangrene.

h) Falling of nail is seen in fungal infection,psoriasis and thyroid diseases.

5) Growth:-

Reduction in blood supply affects the growth of nails. Nail growth is also affected in severe ilness. when the disease disappears the growth starts again resulting in formation of transverse ridges.These lines are called Beau’s lines and are healpful to date the onset of illness.

HOW ALCOHOL AFFECTS THE BRAIN

August 30th, 2009

I once had the unusual, though unhappy, opportunity of observing the same phenomenon in the brain structure of a man, who, in a paroxysm of alcoholic excitement, decapitated himself under the wheel of a railway carriage, and whose brain was instantaneously evolved from the skull by the crash. The brain itself, entire, was before me within three minutes after the death. It exhaled the odor of spirit most distinctly, and its membranes and minute structures were vascular in the extreme. It looked as if it had been recently injected with vermilion. The white matter of the cerebrum, studded with red points, could scarcely be distinguished, when it was incised, by its natural whiteness; and the pia-mater, or internal vascular membrane covering the brain, resembled a delicate web of coagulated red blood, so tensely were its fine vessels engorged.

I should add that this condition extended through both the larger and the smaller brain, the cerebrum and cerebellum, but was not so marked in the medulla or commencing portion of the spinal cord.

The spinal cord and nerves.
————————–

The action of alcohol continued beyond the first stage, the function of the spinal cord is influenced. Through this part of the nervous system we are accustomed, in health, to perform automatic acts of a mechanical kind, which proceed systematically even when we are thinking or speaking on other subjects. Thus a skilled workman will continue his mechanical work perfectly, while his mind is bent on some other subject; and thus we all perform various acts in a purely automatic way, without calling in the aid of the higher centres, except something more than ordinary occurs to demand their service, upon which we think before we perform. Under alcohol, as the spinal centres become influenced, these pure automatic acts cease to be correctly carried on. That the hand may reach any object, or the foot be correctly planted, the higher intellectual centre must be invoked to make the proceeding secure. There follows quickly upon this a deficient power of co-ordination of muscular movement. The nervous control of certain of the muscles is lost, and the nervous stimulus is more or less enfeebled. The muscles of the lower lip in the human subject usually fail first of all, then the muscles of the lower limbs, and it is worthy of remark that the extensor muscles give way earlier than the flexors. The muscles themselves, by this time, are also failing in power; they respond more feebly than is natural to the nervous stimulus; they, too, are coming under the depressing influence of the paralyzing agent, their structure is temporarily deranged, and their contractile power reduced.

This modification of the animal functions under alcohol, marks the second degree of its action. In young subjects, there is now, usually, vomiting with faintness, followed by gradual relief from the burden of the poison.

Effect on the brain centres.
—————————-

The alcoholic spirit carried yet a further degree, the cerebral or brain centres become influenced; they are reduced in power, and the controlling influences of will and of judgment are lost. As these centres are unbalanced and thrown into chaos, the rational part of the nature of the man gives way before the emotional, passional or organic part. The reason is now off duty, or is fooling with duty, and all the mere animal instincts and sentiments are laid atrociously bare. The coward shows up more craven, the braggart more boastful, the cruel more merciless, the untruthful more false, the carnal more degraded. ‘ In vino veritas ‘ expresses, even, indeed, to physiological accuracy, the true condition. The reason, the emotions, the instincts, are all in a state of carnival, and in chaotic feebleness.

Finally, the action of the alcohol still extending, the superior brain centres are overpowered; the senses are beclouded, the voluntary muscular prostration is perfected, sensibility is lost, and the body lies a mere log, dead by all but one-fourth, on which alone its life hangs. The heart still remains true to its duty, and while it just lives it feeds the breathing power. And so the circulation and the respiration, in the otherwise inert mass, keeps the mass within the bare domain of life until the poison begins to pass away and the nervous centres to revive again. It is happy for the inebriate that, as a rule, the brain fails so long before the heart that he has neither the power nor the sense to continue his process of destruction up to the act of death of his circulation. Therefore he lives to die another day.

HERNIA

August 28th, 2009

Introduction

Hernia is an abnormal protrusion of internal organs through an abnormal opening in the wall of the cavity.A combination of increased pressure inside the body with weakness in the wall is responsible for this condition.In this condition internal organs or parts of organs are protruded out forming a swelling which will increase the size with coughing and lifting weight,and while passing stool and urine.In lying down position the swelling goes inside except in strangulated and irreducible hernia.

Causes:-

1, Weakness in the body wall:–

a) Congenital weakness.

b) Acquired weakness due to injuries,wasting of muscles,suppurative lesions in the wall and presence of weak natural openings,obesity,lack of exercise,repeated pregnancy.

c) Surgical operation with improper suturing or sepsis of operated site.

2) Increased pressure inside the body.

a) Chronic constipation.

b) Recurrent cough.

c) Weight lifting.

d) Stricture of urethra.

Common sites for hernia:–

Hernia can occure anywhere in the body.However there are some common sites for hernia.Due to the presence of hard bony covering chest wall is normally not affected.Hernia in the lower back is also rare due to spine and back muscles and tough ligaments and sheeths.The common site for hernia is abdominal wall.Compared to other parts the abdominal wall is weak due to the presence of some natural orifices.There are some areas wherein the abdominal muscles are weaker and thin and all these factors make a chance for herniation.The common sites for hernia are following.

a) Inguinal hernia:

Here the abdominal contents protrude through the inguinal canal (passage in the lower abdominal wall just above the inguinal ligament.It is seen on either side).This type is common in males.Initially the swelling comes only while straining and goes back while lying down. Later the large portion of intestine may come out which may not go back easily.

b) Femoral hernia:

This type of hernia is more in females.Here the abdominal contents pass through the femoral canal which is seen just below the junction between the thigh and lower abdominal wall(Inside the femoral triangle).The contents pass downwards and comes out through saphenous opening in the thigh and forms a swelling under the skin.

c) Umbilical hernia:

This is common in children.The umbilicus is the weaker part of the abdomen.The contents of the abdomen may protrude as a bulb like swelling while crying and defecating.

d) Incisional hernia:

These hernias are seen in operated sites. Due to improper suturing or sepsis the operated site becomes weak resulting in hernia.

e) Epigastric hernia:

Here the hearniation occures in the epigastrium. It is a rare type.

f) Lumbar hernia:

Here the hernia appear in the lumbar area on either side of the lumbar spine(in the lumbar triangle).This is also a rare type.

g) Obturator hernia:

This is a rare type of hernia. Here the contents pass through obturator foramen in the pelvic bone.

Complications of hernia:–

1) Strangulation:

If the hernial orifice is narrow the abdominal contents may not go back easily, and later the blood flow to the herniated tissues may be blocked due to constricition.This can cause death of protruded intestine.

2) Intestinal obstruction:

This occures when the whole portion of the intestine is protruded in to the hernial sac. The narrow hernial orifice will block the passage of bowels.

3) Infection and peritonitis:

If there is strangulation with death of a portion of intestine there will be spread of infection to the abdomen resulting in peritonitis.

Treatment of hernia:–

Initial treatment: In the initial stages of hernia the following steps may be useful

1) Use of hernia belt:

Special types of hernia belts are available for each type of heania.This will prevent the protrusion and will reduce pain.

2) Constipation,recurrent cough,urinary obstruction ect should be treated.

3) Fat reduction will increase the strength of abdominal wall.

4) Abdominal exercises to increase the muscle tone.

5) Take plenty of leafy vegetables, fruits and fibrous diet for easy bowel movements.

6) Try other systems like Homoeopathy,Herbal medicine and ect

If no relief by the above steps consult a general surgeon for surgical management.

Surgical treatment.

The following operations are done depending up on the type and nature of hernia.

1) Hertniotomy : In this operation the contents of hernial sac is pushed in to the abdomen and neck of the sac is ligated with transfixion ligature and the sac is cut off.

2) Herniorrhaphy: Here along with herniotomy the posterior wall is repaired.

3) Hernioplasty: This operation is done if herniotomy is not possible due to wide neck of the sac.Here the repair is done with the healp of non absorbable materials like tantalum gauze,polypropylene mesh or stainless steel mesh.

Exercise and Arthritis

August 28th, 2009

Your bones hang out in a lot of joints. Knee joints. Hip joints. The joints in your fingers and the joints in your toes.

Wherever bones meet, there is also cartilage, a rubbery, protective layer that ensures your joints bend smoothly and painlessly. But even cartilage cannot do this tremendous job alone. A thin membrane called the “synovium” provides fluid that lubricates the moving parts of the joint. When the cartilage wears out of the synovium becomes inflamed, the result is generally a case of “osteoarthritis” or “rheumatoid arthritis.”

In osteoarthritis, the cartilage can be eroded so much that bone does rub on bone. Thos type of arthritis develops gradually over a lifetime as a simple result of the wear and tear placed on your joints over the years. Very few people escape some degree of osteoarthritis, though the severity varies a great deal.

As a matter of fact, if you are over the age of 50, you are likely to have at least one joint affected by osteoarthritis. Osteoarthritis affects men and women equally and is by far the most common type of arthritis, with almost 16 million Americans in the list.

In rheumatoid arthritis, damage to the synovium is at the source of trouble. Doctors and researchers are not absolutely sure what causes it, but most think that rheumatoid arthritis is a disease in which the immune system actually attacks certain tissues in the body, including those that connect the joints and the synovium.

Rheumatoid arthritis begins with swollen, red, stiff, and painful joints, but it may progress until scar tissue forms in the joint or, in extreme cases, until the bones actually fuse together. Almost 75% of the 2 million people with rheumatoid arthritis in the United States are women. The disease can hit as early as teen years.

Exercising Your Prevention Options

Investing a little time in developing a good weight-bearing low-impact exercise and stretching plan can add up to great results when it comes to staving off arthritis pain. Strong muscles help protect the joints from wear and tear, and the movement keeps joints flexible.

That is why the quest for fitness is at hand, even if you are 50 years and over. However, most Americans over 50 are still right where they always were sitting back and watching others jog by. Most of them contend that that is just for people who have been athletic all their life, or some say exercise is for young people and engaging into exercise will do them more harm than good.

There are still some that insist on excusing their selves in exercise routines because they do not just have time or they have less energy than ever before. These are all lame excuses. Hence, it is time to start to get rid of those pains. Start exercising.

Consequently, preventing arthritis is not an exact science, but physicians have discovered a few ways to lower your risk. Here is how:

1. Do not weight around

The single most important measure anyone can take to prevent osteoarthritis of the knee is to lose weight if they are overweight. Extra weight puts extra stress on your knees. If you are 10 pounds overweight, for example, you put 60 pounds per square inch of extra pressure on your knees every time you take a step. That extra pressure can slowly but surely erode the cartilage in your knees, leading to arthritis.

A study has clearly supported the theory that weight loss weighs in on the side of prevention. In the study, overweight women who lost 11 pounds or more over a 10-year period decreased their risk of developing osteoarthritis of the knee by 50%.

2. Stretch those muscles

Any kind of stretching is good as long as you do not bounce, which can lead to a muscle pull. This is according to some of the professors of clinical medicine in New York City.

Try to hold a slow, steady stretch for 15 to 20 seconds, then relax and repeat. It is best to flex up by stretching before any exercise, especially running and walking. But it is also a good idea to stretch each day. Ask your doctor to teach you stretches that focus on potential arthritis trouble spots, such as the knees or the lower back.

3. Walking is always the best exercise

Take a good long walk at least three times a week or participate in a step-aerobics or low-impact exercise routine maximum results. There is no proof that running is bad for the joints, but remember, it may aggravate an injury if you already have one. Just remember to check with your doctor before starting a new exercise program.

The bottom line is that of all the healthful habits, exercise is the most important. This is because people are designed to be active. Hence, it is really important for people to exercise in order to stay healthy and keep those joints free from wear and tear.

Just keep in mind that the unexercised body, even if free from the symptoms of illness or problems like arthritis, is not at its full potential. Hence, start exercising right now!

Benefits of Fish Oil for Fitness and Health

August 28th, 2009

When the words oils and fats are mentioned, health-conscious individuals tend to run for cover. What they fail to realize is that there are good fats and bad fats. Complete avoidance of intake of oils and fats would actually be detrimental – rather than beneficial – to their health.

The Truth about Fish Oil
Essential fatty acids must always be part of our daily diet – without them, we take one step closer to our deaths. Essential fatty acids are divided into two families: omega-6 EFAs and omega-3 EFAS.

Although there are only very slight differences to distinguish the two groups of essential fatty acids from each other, studies have revealed that too much intake of omega-6 EFAs can lead to inflammation, blood clotting and tumor growth. The good news, however, is that the opposite is true for omega-3 EFAs. Omega-6 EFAs can be found in vegetable oils while omega-3 EFAs can be found in fish oils among other foods.

Omega-6 vs. Omega-3
Physicians and scientists are of the same opinion that the cause behind increasing cases of heart disease, hypertension or high blood pressure, obesity, diabetes, premature aging and certain kinds of cancer is none other than an imbalanced intake of omega-3 and omega-6 EFAs.

As mentioned earlier on, omega-6 EFAs can be found in vegetable oils. This includes but is not limited to corn oil and soy oil, both of which contains high amounts of linoleic acid. Omega-3 EFAs on the other hand can be found also in marine plankton and walnut and flaxseed oils. It should be significant to take note that fatty fish and fish oils contain eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), fatty acids that have been observed to provide many benefits to the human body. In the early 1970’s, a study on Greenland Eskimos have revealed that one of the major reasons why they rarely suffer from heart diseases is because of their high-fat diet (mainly composed of fish).

The two essential fatty acids, EPA and DHA, are also helpful in preventing atherosclerosis, heart attacks, depression and various forms of cancer. Fish oil supplemented food have also proven to be useful in treating illnesses like rheumatoid arthritis, diabetes, Raynaud’s disease and ulcerative colitis.

Other Benefits of Fish Oil
There are a lot more illnesses and situations in which intake of fish oil has proven to be significantly beneficial.

Making the Heart Healthier
The heart is inarguably one of the most important parts of our body and having an unhealthy heart means having to suffer a rather limited lifespan. Naturally, it’s in our best interests to keep our hearts happy and healthy and one way of doing that is eating food that contains fish oil.

In Athens, Greece, for instance, a study was made to show if there was a direct relationship between high fish diet and inflammation of blood vessels. The results revealed that those who ate more fish than the others had a lower level of C-reactive protein and interleukin-6, factors that are commonly used to measure likelihood of blood vessel inflammation. These benefits remained even when the various risks associated with high fish diet were taken into account.

Fish to Become Thin
In Perth, Australia, a study had revealed that fish consumption can be used against hypertension and obesity. Researchers of the UWA (University of Western Australia) have discovered that a weight-loss diet which includes a regular amount of fish consumption can be quite effective in reducing blood pressure and improving glucose tolerance.

Fish Oil to Combat Asthma
People suffering from respiratory problems like asthma tend to be perceived as unfit and unhealthy. They should now be pleased to learn that certain studies have revealed the benefits of fish oil for asthma-burdened-individuals. Statistics show that approximately 20 to 25% of children today suffer one form of asthma or another at a certain point in their lives. And certain evidence reveals a regular diet of food with high linoleic acid content as the reason behind it.

Researchers of UW (University of Wyoming) conducted a study by subjecting a number of children to a high-fish diet while others continued with their regular diet. Results revealed that the participants who ate more fish were less prone to asthma attacks and were able to breathe more easily as well.

Consult Your Nutritionist Now
Nothing is good when consumed or used excessively but complete avoidance of a particular food type is equally harmful as well. Ask your nutritionist for the right amount of fish intake for your age and health status.

Benefits of Detoxing for Fitness and Health

August 27th, 2009

It seems to be a little disgusting when you are detoxing or cleansing. Your body shows some signs that you have built up toxins. These toxins can affect your whole body fitness and health.

There are times that you feel sluggish and feel the stressful. Your body may experience continuous aching, diarrhea, constipation, and feeling of clumsiness. Rapid weight gain and the incapacity to lose the excess weight can also be signs of having toxins in the body.

Moreover, the toxins found in the body are found and stored on your fat cells. For Americans who are taking the usual American diet, a person may consume 70 trillion garbage cans for each cell. In detoxing your body and cleaning that unwanted garbage in your cells, you should pay attention on your elimination organs.

There are particular organs in your body that deal on cell waste management. These organs play a major role in the detoxing process for a fit and healthy body.

1.    Your liver is the organ that recycles the unwanted chemicals in the body. It sorts out the toxins and places them to the organ for elimination during the process of circulation. The principal elimination organs will back up the liver on where these toxins will be stored and then eliminated.

2.    The lymph glands also play an important role in eliminating the toxins. A network of tubing brings out the excess waste of the cells from the body and to the final eliminating organs. The appendix, thymus, tonsil, and spleens are major lymphatic glands that help the major organs of the body in cleansing and detoxing.

3.    The kidneys help in the water management of the body. They are the ones that keep the good chemistry of the blood alkaline by eliminating the dissolved acid waste. You can help your kidney to function very well by drinking plenty of water. It is much better if you drink fresh alkaline juices and purified water. You may take ½ ounce of alkaline everyday to see positive results on your body weight.

4.    The lungs are the organs that keep the blood air purified. They allow the oxygen to go directly to the bloodstream. It is also responsible in removing waste gases that are found in every cell of the body. Deep breathing and fresh air is very helpful in keeping the lungs healthy and free from toxins. If you are in the urban area, it is recommended that you find an oxygen rich area where you can perform deep breathing.

5.    The colon is a solid waste management organ in your body. Medical practitioners have found many peolpe that may have an 80-pound mucus and rubber like solid waste that are found on the walls of the colon. Detoxing and cleaning the colon can be a real tough thing to do. However, having a free waste colon can certainly provide you good benefits of having a clean and healthy body.

If you are experiencing some signs of detoxification, you may try doing a regular walking exercise. Exercise is a good key in having a fit and healthy body. Many diet doctors also suggest that you drink plenty of lemon water. This is an effective way of maintaining a very good circulation and can increase the rate of detoxification inside the body.

How to Read Food Labels

August 27th, 2009

You cannot measure every morsel that passes your lips, but it is a good idea to measure most foods and beverages until you get a feel for portion sizes.

It is a supersized world out there, and most people are surprised to find that their idea of a single serving is actually two or three.

If you are into bells and whistles, there are food scales that are preprogrammed with nutritional information, as well as scales that will keep a running total of your daily food and nutrient intake for you. The only tools you really need, however, are a simple and inexpensive gram scale, dry and liquid measuring cups, and idea on reading food labels.

Among all of the mentioned tools, reading food labels seem to be the most effective way of determining the right kind of food to be bought in the supermarket. It lets you make sensible food selections. Through the “Nutrition Facts” section in a particular item in the grocery, you can identify the amount of serving sizes provided in that product.

With food labels, you can clearly understand the amount and kinds of nutrients that are provided in the item. Usually, it contains the information on saturated fat, sodium, total fat, fiber, and cholesterol amount “per serving.”

However, understanding and reading these food labels can be very perplexing. A typical consumer would definitely ask what those numbers mean and how it will affect her diet intake if ever she will religiously follow the serving guide as stipulated on the food label.

To further have a clear and more comprehensive understanding of the items stated in the food label, here is a list of things that you need to know:

1. Serving size

This is the primary item you will see in a food label.

The amount of servings stated in the food label refers to the quantity of food people usually consume. However, this does not necessarily mean that it reflects your very own amount of food intake.

Moreover, serving size determines the amount of nutrients that enters the body. This means that if you will follow strictly what the serving size is, you will obtain the same amount of nutrients according to the serving size that was given in the label.

For instance, if the serving size says one serving size is equal to 54 grams, that would mean you have to measure 54 grams and eat that and you have just eaten one serving. So to speak, the amount of nutrients stated in the food label is the same amount that has entered your body considering the fact that you have just eaten 54 grams.

However, if you have eaten everything, and the food label says that each pack is equivalent to 4 servings, you have to calculate the amount of nutrients that have entered your body. This means that if the food label says 250 calories per serving that means you have to multiply it to four to get the total amount of calories you have taken.

2. Nutrients

This refers to the list of available nutrients in a particular item. It is also where the nutritional claims of the product based on the recommended daily dietary allowance are stated. Usually, the nutritional amounts are based on both the 2,500-calorie diets and the 2,000 recommended dietary allowances.

In order to understand the numeric value of each item, you should know that the “% daily value” that the food label indicates is actually based on how a particular food corresponds to the recommended daily dietary allowance for a 2,000 calorie.

If in the event that you have purchased an item that has a dietary allowance different from the 2,000-calorie diet, you just have to divide the stipulated amount by 2,000 and you will be able to identify the “%daily value” for the nutrients.

3. Ingredients

This refers to the list of the ingredients that were used to manufacture the product. The listing is usually arranged from the main ingredients that have the greater amount by weight up to the smallest quantity. This simply means that the actual quantity of the food includes the biggest quantity of the main ingredient or the first item and the minimum amount of the very last ingredient.

4. Label claim

This refers to the kinds of nutritional claims of a particular food item. For instance, if an item says it is sodium-free, it has less than 5 milligrams per serving or a low fat item actually contains 3 grams of fat or less.

Indeed, reading food labels can be very tedious and confusing. Nevertheless, once you get the hang of it, it would be easier for you to watch your diet because you can already control the amount of food that you take.

Heart Rate Monitors

August 27th, 2009

Heart rate monitors used to be exclusively operated by physicians and nurses alone but that was soon rectified with today’s multi-tasking generation. Every person seemed to want to know about everything that was related to them and that of course included monitoring their own heartbeats.

What is a Heart Monitor
Also known as a cardiac monitor, a heart monitor is a piece of electronic equipment that can be used to track or observe heart functions continuously. It allows people to place a numerical value on their healthiness based on their heart rate and have a target heart rate to work for. The more complex versions of the heart monitor allow physicians to see any signs of deterioration or improvement and make the necessary adjustments immediately.

Types of Heart Monitors
Today, heart monitors are produced by the millions and designed to cater specific types of individuals. Some heart monitors are primarily designed for weight loss programs while others are meant for the use of athletes or fitness programs. Some are wireless or come as a built-in feature of exercise equipment like a treadmill or an exercise bike. It can be strapped to your wrist or of considerable size. It may or may not emit any electromagnetic waves, depending on its purpose. A fetal heart monitor, for instance, must not produce any waves at all as this may affect the health of the baby.

Factors on Selecting the Best Heart Monitor for You

ECG-Accurate Monitors with Chest Straps – Heart monitors that come with chest straps are more often not the most accurate of heart monitors. The chest strap is strapped around your chest, a few centimeters below your breast. It contains a device that’s able to detect electrical activity of your heart and transmit it to the brain of the machine – just like an ECG. The results are shown on the display monitor, which most of the times is attached to your wrist like a watch. Others however prefer results to be transmitted through audio messages via earphones.

Upon choosing heart monitors with chest straps, you need to remember to keep the strap constantly connected to your body lest you want the heart monitor to produce inaccurate readings.

Lastly, the only alternative against buying heart monitors with chest straps are the ones that rely on pulses on your fingertips. These however do not provide readings as accurate as those with chest straps.

Heart Monitor Features – Basic and lower end models tend to display only your heart rate and maybe the elapsed exercise time as well. This of course does not provide sufficient information if you want to know exactly how much you need to improve before you can be qualified as a completely healthy individual. Higher end models will naturally offer a wider range of features – for a price. Examples of such features are – but not limited to – heart rate zone alarms, timers and number of calories burned. It may also allow users to set pre-programmed workouts along with a targeted heart rate.

Ease of Use – Lastly, you must purchase a heart rate monitor that you will have no problems of using. What good would a high end heart monitor do if it takes you an hour to operate it? Are the numbers and words appearing in the heart rate monitor readable? Can it be used in no-light situations? Are buttons well-labeled and ergonomically positioned?

To Buy or Not to Buy a Heart Monitor
Heart monitors can be especially costly, more so if you are intent on purchasing higher-end models. If you have a limited budget, you should ask yourself whether or not you truly need to buy a heart monitor. You can of course purchase one of the lower-end models but low quality heart monitors can lead to inaccurate results and that sort of defeats the purpose of buying one.

If you are intent on purchasing a heart monitor, you need to ask yourself another question: do you need to make a solo purchase or is it alright with you to use the heart monitor that comes as a built-in feature of a treadmill? Lastly, you should remember as well that you can always pay your doctor regular visits and have him monitor your heart rate for you.
