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.

A Healthy Guide to Good Nutrition

Friday, September 25th, 2009

Whether you are at your ideal weight or striving to reach your weight goal is it simply a matter of burning more calories than you take in? The answer, I suggest, is no! Overall body health improvement as well as weight gain or loss must be factored in to the equation or you could be heading for problems. Correct nutrition can help to reduce the risk of a miriad of health-related problems, the most frightening of which are surely heart disease and cancer. Proper nutrition, however, entails eating many different foods, monitoring your consumption of some food and beverage items, and counting calories. Good diets offer balanced nutrition that reduces cholesterol, blood pressure, and helps with weight control.

To function properly, your body must have the correct combination of nutrients:

Carbohydrates. They are the primary source of ammunition in your diet. The body uses carbohydrates to build glucose which can be used immediately or stored in your body for later. Too much glucose, however, is stored as fat. There are two types of carbohydrates – simple and complex. Sugars are simple carbohydrates. Starches and fibers are complex carbohydrates.

Proteins. Proteins help your body build and maintain muscles and other tissues. They also function in the creation of hormones. Like carbohydrates, excess protein is stored as fat.
