If we want to have a deep understanding of food, we should start from understanding the basic nutrition diet structure as the foundation, including macronutrients such as the fat, carbohydrates and proteins and then further examine micronutrients in food.
In micronutrients, there are two categories we have been familiar, that is, vitamins and minerals. Other micronutrients more and more known by people are phytonutrients. Phytonutrients are naturally produced substances, with the power to promote human health.
It is the food ingredient different from vitamins and minerals, which has great health benefits. Foods contain thousands of phytonutrients. It appears in every food, from morning drinking tea to popcorn eaten in theatre. Some nutrients help to promote the ability of cells interlinked conduction; some may be anti-inflammatory; some help to avoid cell mutation; some can be spread to prevent the proliferation of cancer cells. Just some of the functions are known by people, and many of the features have not even been discovered.
Here are three important healthy phytonutrients:
Polyphenols: In addition to promoting health, the polyphenol also play a role of antioxidants, with anti-inflammatory and anti-allergic properties. Certain food ingredients contain polyphenols, such as tea, nuts and berries.
Carotenoids: Carotenoids are pigment found in red and yellow vegetables such as tomatoes, pumpkin, carrots, apricots, mangoes and sweet potatoes. This is an important phytonutrients, including β-carotene, lutein and lycopene. These nutrients have antioxidant function, protecting the body against cancer invasion and help fight aging.
Phytoestrogens: Phytoestrogens are natural chemical composition, especially rich in soy foods. In addition, whole grains, seeds, grains, and some fruits and vegetables also contain phytoestrogens. In hormone-related cancers, the phytoestrogens are also influential.
All foods are different. It is a new idea to say some vegetables or fruits are healthier than others. People now can inspect micronutrients contained in fruits and vegetables and determine which fruits and vegetables have more healthy elements.
