All of us have heard of ‘whole grains’. Many of us have also adopted whole grains in our diet. Let us now understand the true meaning of this term and the benefits whole grains have to offer in our daily diets.
What is whole grain?
Whole grains or foods made from them contain all the three essential components (carbohydrates, proteins, vitamins and antioxidants). Some examples of whole grain and whole grain foods include whole wheat, whole wheat flour, daliya (broken wheat), whole grain corn, cornmeal, Whole oats, oatmeal, brown rice, whole barley; millets like whole jowar, bajra (pearl millet), ragi etc. Some pseudo-cereals like amaranth (rajgira) and quinoa are also considered as whole grain.
Once the bran and germ of these grains are removed, the grain is said to be refined. Refined grains are devoid of essential vitamins, minerals and fibre. Some examples of refined grain products are maida and white rice.
Health benefits
Evidence suggests that eating whole grain as part of a well-balanced diet can have a protective effect against lifestyle diseases such as type-2 diabetes, cardiovascular ailments and obesity. Since many of the lifestyle diseases are inflammatory in nature, increased consumption of whole grains can lead to alterations of the gut microbiota which can improve systemic inflammation. Whole grain foods help impart digestive health. For example, the soluble fibre in whole grain oats ferments in the colon and helps keep the colon healthy.
