Personalized medicine is a targeted therapy that aims to provide people
suffering from complex illnesses with tailored-made healthcare. Taking this into
consideration, foods with diverse bioactive compounds have recently gained
widespread scientific interest as alternatives to modern drugs for developing
therapeutic agents against human diseases. Tannins are an important group of
polyphenol compounds in foods that have both beneficial and anti-nutritional effects.
As an anti-nutrient, they can reduce element bioavailability, and protein absorption,
and inhibit enzymatic actions during metabolism. If tannin-rich foods are consumed in
sufficient quantities and at the appropriate time, they may act similarly to natural drugs
that ameliorate a range of metabolic disorders. Thus, the types of tannin-rich foods and
the timing of consumption before or after meals should be considered for maximum
physiological importance in maintaining human health. In this chapter, we compiled
the different types of tannins and their food sources, as well as their beneficial and antinutrient effects on human health.
