You need protein for the repair and growth of the body. Protein is composed of chains of amino acids. There are only twenty common amino acids but they are combined in nature in an infinite number of ways so that proteins differ in structure and in their enzymatic qualities.

In the old days scientists spoke of first and second class proteins. Today we know that out of the twenty amino acids, eight are essential in that the adult cannot make them in the body, and the rest are called nonessential because they can be made from the essential ones.

One more amino acid, histidine, is needed for growing infants, and so is essential to begin with, but not later on. It is a mistake to think of the non-essential amino acids as being without value, for they too are found in the cells of our bodies; it is only that we can do without them if we have to. The essential amino acids are: isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine.

Most vegetable sources of protein are lacking in one or other of the essential amino acids, but eggs, milk, meat and fish contain all the amino acids in the correct proportions. However if you mix grains, seeds, pulses, nuts and legumes so that your diet is not consisting of a single type of vegetable protein, then the biological value of the mixture is excellent.

Indeed such a diet is good because if does not contain the saturated fat commonly present in meat.The body does not need a great deal of protein, provided this supplies the essential amino acids in the right mixture. The unwanted amino acids are converted into heat and energy and not materials for the growth and repair of the cells.

Only recently did the World Health Organization realize that vast sums were being spent on giving too much protein to the starving and under-privileged millions, when all the poor were doing was to convert the excess protein to much-needed energy. When energy providing foods are given instead the protein levels usually do not need supplementation.

With the increasing focus on weight loss and healthy eating, we are subjected on a daily basis to an overwhelming amount of information. It seems that every day brings the advent of some new weight loss product that promises to help us shed pounds and get healthy in one fell swoop. It’s no wonder that we’re all so confused. But those who understand the components of healthy weight loss know that a focus on natural, whole foods can increase your body’s health and bring you to a weight that’s appropriate for you. Many natural food enthusiasts continue to tout the benefits of the green tea diet – using the natural characteristics of green tea to speed the metabolism and achieve optimal health.

It seems that each study yields more benefits of the green tea diet. For instance, green tea – a natural and aggressive antioxidant – will cleanse your body of impurities and help keep your system balanced. The benefits of this are increased immunity against a variety of viruses and bacteria. In fact, some recent studies have shown the promise of a green tea diet in warding off such conditions as Alzheimer’s because of the tea’s ability to fight off certain chemicals that cause plaque build-up on the brain.

Additionally, a green tea diet will afford you a speedier metabolism as green tea has been shown to effectively raise metabolic levels. And if that weren’t enough, it has also been shown that a green tea diet will help your body burn fat, as the properties of green tea efficiently break down fat deposits.

However, for those who must stay away from caffeine, the green tea diet is not for you. Green tea does contain caffeine but is certainly a superlative choice to coffee in addressing your body’s overall health.

Participants in a green tea diet can sip the beverage after meals to help aid digestion and keep metabolic rates increased. Or try substituting your morning coffee with a cup of green tea.

The green diet is in no way a substitute for overall healthy eating and plenty of physical activity. But it can be a component of your new lifestyle of healthy living.
