Functional foods

Functional foods

-By Erin Macdonald, R.D. 

What if I told you that there are certain foods and food compounds that may improve your health, reverse certain diseases, and reduce your risk of cancer, heart disease, and diabetes? Would you be interested in eating your way to better health rather than be popping pills in the morning and evening? Welcome to the world of functional foods.

Functional foods are foods, herbs, spices, supplements, and fortified foods and beverages that contain specific compounds that have been shown to have health-promoting effects. According to the International Food Information Council Foundation, the top ten functional foods are: Fruits/vegetables, fish/oil, dairy, herbs/spices, whole grains, fiber, meat/poultry, tea/green tea, nuts, and supplements. Foods in each of these categories contain at least one important compound that has health promoting properties. From lutein, which supports the maintenance of eye health, to omega-3 fatty acids found in fish and flaxseeds, the antioxidant and anti-inflammatory benefits of these vitamins, minerals, antioxidants, and fibers are too great to ignore.

Here are a few of these functional components, the foods in which they are found, and their health benefits:
