According to definition foods including fortified, enriched, enhanced components or dietary components that may reduce the risk of chronic disease are called functional foods.
Whereas foods beyond the traditional nutrients due to enhancement are called functional foods.
Understanding of the relationships between food, physiological function, and disease have progressed in recent years, particularly over the past decade.
Classification Of Functional Food
There are several types of Functional Foods and are described as below
Conventional foods
Garlic, Nuts, & Tomatoes
Modified foods
Fortified, Enriched, Enhanced Iodized salt, Folate-Enriched breads, Energy bars, Snacks, & Yogurts formulated with bio-active components

I believe Soy Isoflavone play a role in prostate cancer prevention
Conclusion
Functional foods are on peak demands because of increasing consumer awareness for healthy living, the ageing population, increasing health care cost, advancing scientific evidence that diet can effect prevalence and progression of disease.
We should take functional foods under proper supervision of a nutritionist or other medical assistant if possible.
