The Essential Buzzwords From Dietary Science

By Kathy P Bates

A great deal of research is currently being conducted in the field of nutrition. Many vital and significant nutrients that were unknown in the past are now being exposed. Consequently, there are a lot of dietary buzzwords in the modern literature that one may not recognize such as phytonutrients, polyphenols, carotenoids, anthocyanins and Omega fatty acids.

The basic classifications for foods are protein, carbohydrates and fat. Everyone is familiar with these macronutrients. As we go further, most people are also familiar with vitamins such as A, C, E, D and B complex and the minerals such as calcium, zinc, chromium and magnesium. But there are also hundreds of "micronutrients". These are substances that are required in less significant quantities but are still essential. They include phytonutrients, polyphenols, carotenoids, anthocyanins and Omega fatty acids.

Phytonutrients are a non-mineral, non-vitamin, organically occurring component of food that offers wonderful health advantages. Important phytonutrients include polyphenols, anthocyanins, carotenoids and phytoestrogens.

Polyphenols are an antioxidant. They were in earlier times acknowledged as vitamin P, but the name changed as they were found to be very different from a usual vitamin. Polyphenols have anti-inflammatory and antiallergenic properties. You can get polyphenols from most berries, tea, red wine, coffee, dark chocolate, pomegranates and more.

The orange-red pigment that is so usual in nature and found in red, yellow and orange fruits and vegetables such as pumpkin, carrots, apricots, sweet potatoes and tomatoes is called Carotenoids. Carotenoids convert to vitamin A in the body, as they are a vitamin A precursor. Carotenoids can shelter us from cancers and the damaging effects of aging.

Anthocyanins are the deep blue to purple pigment that gives blueberries, blackberries, strawberries, red cabbage and more their deep, brilliant colors. Anthocyanins can provide possible health effects against aging and neurological diseases, cancers, inflammation, diabetes and bacterial infections based upon laboratory substantiation.

Omega Fatty Acids include Omega 3, Omega 6 and Omega 9. These are known as essential fatty acids because our bodies lack the ability 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 good for your health cell membranes, which are vitally significant for the proper development of the eyes, a healthy cardiovascular system and a high functioning immune system.

There are increasingly more benefits that are being discovered about these vital micronutrients every day. In order to get these critical nutrients in your diet you need to consume a diversity of beneficial foods every day. - 17273
