Defining The Indispensable Buzzwords Of Nutritional Science

By Kathy P Bates

These days there are a lot of "buzz words" when it comes to nourishment. Science has found an large quantity of nutrients that were not identified before. It is easy to get confused when you hear such words as phytonutrients, polyphenols, carotenoids, anthocyanins and Omega fatty acids. What do they all mean?

Everyone is familiar with protein, fat and carbohydrates as they are just the simple classifications of food. Break them down and there are the essential vitamins such as A, C, E, D, E and the B complex and the necessary minerals such as calcium, zinc, chromium and magnesium. But science has found that there are also hundreds of "micronutrients". These are nutrients that are necessary in smaller quantities but are still important. This would include the phytonutrients, polyphenols, carotenoids, anthocyanins and Omega fatty acids.

A phytonutrients is a non-vitamin, non- mineral, naturally occurring part of foods that offers noteworthy health benefits. Vital types of phytonutrients include polyphenols, carotenoids, anthocyanins and phytoestrogens.

Polyphenols are a substance that acts as an antioxidant. This collection of nutrients was in earlier times identified as vitamin P. They have anti-inflammatory properties and they are antiallergenic. You can discover polyphenols in berries, tea, red wine, and dark chocolate, coffee, pomegranates and more.

Carotenoids are found in the orange foods such as pumpkin, carrots, apricots, sweet potatoes and tomatoes. It is actually the orange-red pigment that lends the brilliant colors to these foods. Carotenoids are a vitamin A precursor, which means that our bodies are able to construct vitamin A from them. Carotenoids protect us from the negative effects of aging and many cancers.

The pigment that makes the deep blue to purple colors of nature is called anthocyanins. This is the pigment accountable for the deep almost black purple of a blueberry and a blackberry and the brilliant purple of purple cabbage. Anthocyanins are found in excessive concentration in red wine, berries and more. They provide likely health benefits against neurological diseases and aging, cancers, inflammation, diabetes and bacterial infections according to laboratory evidence.

Omega Fatty Acids include Omega 3, Omega 6 and Omega 9. These are known as essential fatty acids because our bodies lack the capability to create these fats in our bodies and we must get them from our diet. Our modern diet provides much more Omega 6 than Omega 3 yet we need a advantageous ratio of 1:1 for these crucial fats. Omega 3 Fatty acids are a critical component of healthy cell membranes, which are vitally important for the proper development of the eyes, a healthy cardiovascular system and a high functioning immune system.

Nutritional science is finding more and more more support of the value of these fundamental micronutrients every day. In order to get the uppermost nourishment you need to eat a range of good for you foods every day. - 17274
