Epidemiologic studies suggest there are bad foods and good foods. BAD: red meat, processed meat, grilled meat, dairy, animal fat, partially hydrogenated fats. Good: Fish, fruits, vegetables, tree nuts, omega-3 fatty acids, whole grains. The article goes on to say: “Foods with epigenetic effects include green tea, cruciferous vegetables, and grapes. Usually we hear about antioxidants and foods. Antioxidants are important but there are beneficial substances in foods called polyphenols which can affect genes. Of the polyphenols, different forms exist but flavonoids are the most highly cited for health benefits and are found in a variety of vegetables and fruits. Types of flavonoids include flavanols in tea, isothiocyanate in cruciferous vegetables, anthocyanidins in grapes and berries, flavonone in citrus fruits, flavonols in onions, isoflavones (genistein) in soy.” This is more confirmation of how important plant-based foods are for human development and health. The field that tries to form a link between epigenetic affects and diet items is called nutrigenomics. Nutrigenomics is one of the main points of this BLOG.
