Although not yet scientifically established, research show that Phytonutrients contribute to human wellness like improving eyesight and reducing the risks of certain types of cancer. Moreover, some studies have found that they serve as antioxidants, antibacterial/antiviral agents and that they stimulate the immune system.

Here are some of the most popular Phytochemicals among many others.

Beta Carotene - It promotes better cardiovascular activity and helps in the formation of bones and teeth. Dietary sources include sweet potatoes, goji berry, and spinach.

Vitamin C - Not only is this a common food supplement, but Vitamin C is also known to be an optimum aid for the immune system, and protects our body cells and their DNA. Citrus fruits are some of its best and abundant sources.

Lycopene - The red pigment found in tomatoes and other red fruits, is an antioxidant that facilitates metabolism by preventing the formation of free radicals which damage the cells. Other fruits and vegetables rich in Lycopene are tomatoes, watermelon, papaya and red bell pepper.

For most people who are not so much a veggie fan or prefer other sweets for their sugar craving, you might start to rethink and consider injecting something healthy in your diet. And the next time you dine and munch over a bowl of fresh produce salad or drink your glass of fruit shake, think about the many benefits you can derive from it.
