All About Protein

Tuesday, February 16th, 2010

Proteins are very important to our bodies. It isn’t just for bodybuilders who use them to gain muscle mass. Those who are sick use them to rebuild damaged tissue and even in normal states, our body uses protein for many different tasks.

Proteins are made of amino acids that are folded together. There are essential amino acids – those that our body cannot make, and non essential amino acids – those that our body can make. Proteins that are made up of all the essential amino acids are said to be complete while those that lack in one or more essential amino acid are incomplete. Complete proteins come from sources such as meat, eggs, cheese, dairy and soy. Incomplete proteins come mainly from vegetable sources with the one exception being soy.

All About Fats

Thursday, January 14th, 2010

With the low carbohydrate craze, many people have turned their attention to fats. They eat more of it and think its fine. Depending on what kind of fat you are consuming and how much of it you take in, fats can be beneficial or detrimental to your health.

There are three main types of fat. They are saturated, unsaturated and trans fats. Saturated fats come mainly from animal sources such as meat and dairy. At room temperature, saturated fats are solid. Unsaturated fats come mainly from plant sources such as olives and nuts and contain no cholesterol. They are liquid (oil) at room temperature. Unsaturated fats are broken down further in monounsaturated (one double bond) and polyunsaturated (more than one double bond).

All About Carbohydrates

Saturday, December 26th, 2009

Normally carbohydrates are found in all foods except meat products. Recently, some diets have recommended stripping out all carbohydrates from what you eat. Many companies have bought into this and among other things, have introduced low-carb breads. Limiting bad carbohydrates such as sugar from your diet is a positive step but going further and refusing to eat fruits and whole grains can potentially deprive you of cancer fighting foods.

Carbohydrates can be broken down into two main categories; simple and complex. Sodas, candy and even fruits contain simple sugars while whole grains, fruits and cereals contain complex carbs. The main difference between the two groups are their chemical structures. Simple sugars are made up of a few sugar molecules while complex carbs are made up of hundreds and even thousands of these molecules put together. In you body, the end product of both is glucose.

Addictive Foods and their Harmful Consequences

Friday, November 6th, 2009

Most of us are fond of at least one product that has the effect of a stimulant and that eventually becomes an addiction. These products include exercise stimulant drinks (they come in cans and look like cola), fizzy aerated drinks, tobacco, betel nut, betel leaf, strong coffee, strong tea, mahuang (an ephedrine-like compound consumed in china), and alcohol.

Before I tell you why we shouldn’t consume these products, I’d like to deal with the question of why we do consume them in the first place.

There’s no one who doesn’t know that products like these, consumed in excess, can severely harm our bodies. Yet, we still find them hard to resist. The need to eat stimulant food is a simple human weakness that has existed for ages: humans (and many animals) have always indulged in foods that give a sort of emotional high. In clinical terms, this means rapid heart beat, a little sweating, dilation or constriction of the pupils of the eye, a warm flush on the face, and a sense of greater sensitivity, concentration and perception.

These sensations of ‘high’ die down within a few hours, and we are left feeling listless and low. This leads to a craving for that food again, to experience the high one more time. And there we are going round and round in a vicious circle.

The physiology of addictions is as follows:

When you eat an addictive food, it stimulates the hormone like substances found at the end of your nerves, which triggers an avalanche of similar stimulatory substances and you experiences a high. As the substances near the nerves are depleted, you get into the low phase, which leads you to crave that food again. This yo-yo phase of nerve stimulation and depletion leads to a pattern of addiction.
