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.

Antioxidant Supplement

Thursday, October 22nd, 2009

The focus of research on vitamins these days is how antioxidant supplements may play a role in reducing the risk of cardiovascular disease. Antioxidant supplements – E, C, and beta-carotene (a form of vitamin A) – have potential when it comes to health promotion. However, most data available about such health promoting properties of antioxidant supplements are incomplete. And only up to 30 percent Americans are taking some form of antioxidant supplements.

But what exactly are antioxidants and how important are they?

Antioxidants come in two forms. They can either be vitamins or minerals. They help prevent oxygen from reacting with other chemicals in cells. Such reactions – called oxidation – could lead to cell damage which may result in heart disease and cancer.

Antioxidants can be found in a variety of foods, but they are far more common in fresh fruits and vegetables. A health diet of fresh produce could lead to high levels of antioxidants in your body, which could only mean one thing – less free radicals (those harmful molecules that cause cell damage) and a healthier you.

When antioxidants start to work, they destroy the free radicals or break the chain. You see, here’s what happens when you have lots of free radicals in your body. Because they are highly unstable, these free radicals have the tendency to steal or get electrons from stable molecules and in so doing, make those molecules unstable as well, turning them into free radicals. This becomes a long chain and will go on and on until such a chain in broken. This is where antioxidants come in whose sole function is to break the chain and neutralize free radicals.
