A macrobiotic diet (or macrobiotics), from “macro” (long) and “bios, biot-” (life) is a dietary regimen which involves eating grains as a staple food supplemented with other foodstuffs such as local vegetables, avoiding the use of highly processed or refined foods and most animal products. Macrobiotics also addresses the manner of eating by recommending against overeating and requiring that food be chewed thoroughly before swallowing. Macrobiotics writers present it as a means of combating cancer.
A staple food, sometimes simply referred to as a staple, is a food that is eaten routinely and in such quantities that it constitutes a dominant portion of a standard diet in a given population, supplying a large fraction of the needs for energy-rich materials and generally a significant proportion of the intake of other nutrients as well. Most people live on a diet based on just a small number of staples.Most staple foods are derived either from cereals such as wheat, barley, rye, maize, or rice, or starchy tubers or root vegetables such as potatoes, yams, taro, and cassava
