The enriched oats are source of magnesium, selenium, phosphorus, magnesium, zinc (Friedman 1996 and George Metljan Fundation 2008). .
Oats are effective in reducing bad cholesterol by action of beta-glucan fiber and also help to prevent heart diseases. Avenanthramides are natural antioxidants in oat that prevent damage from free radicals in LD cholesterol (Thermo Sc. Inc. 2011). Medical studies reported that beta-glucan not only helps to prevent heart diseases, but also contributes to boost the immune system in response to bacterial infections and stabilizing type 2 diabetes. Among the antioxidants in oats, researchers have identified vitamin E, tocotrienols, phenolic acids and phytic acids (Munk 1972). Some of these are short-term release and others long-term release allowing better absorption throughout the intestinal tract. Evidence has been found in medical studies, that oat helps to prevent colon and stomach cancer (Munk 1972 and Thermo Sc. Inc. 2011). .
Wheat, is considered as an ancient grain domesticated by ancient Asiatic cultures. It was thought to be originated in southwestern Asia and it has been consumed as food for more than a thousand years (Leff et al. 2004). Ancient Greek, Roman and other Mediterranean cultures used it for religious ceremonies. Nowadays, the largest commercial producers of wheat are Russia, USA, China, India, Canada and France (George Metljan Fundation 2008). The geographical distribution is broad, but temperate zones are the most favourable for wheat growth (Kato Yokoyama 1992). The non-processed whole wheat is considered a great source of fiber, vitamins B1, B2, B3, E, folic acid, calcium, phosphorus, zinc, copper, iron, manganese, magnesium and fatty acids (Plaza et al. 2003). In 1941, USA implemented a law to enrich of processed wheat; they added vitamins B1, B2, B3 and iron. .
Therefore, the health benefits depend on the form in which the wheat is consumed and the percentage left from extraction processes (Plaza et al.
