macrobiotic

adj. of or pertaining to macrobiotics; long-lived

Macrobiotics, from the Greek "macro" (large, long) and "bios" (life), is a dietary regimen that involves eating grains as a staple food supplemented with other local foodstuffs such as vegetables and beans. Although in macrobiotics people may opt to use Japanese ingredients (Japan being the cradle of contemporary Macrobiotics), according to the general guidelines people should use the ingredients that are found locally (e.g. mustard instead of ginger), and avoid the use of sugar and other highly processed or refined foods. Macrobiotics also addresses the manner of eating by recommending against overeating and requiring that food be chewed thoroughly before swallowing.

Adjective
1. of or relating to the theory or practice of macrobiotics; "macrobiotic diet"
(pertainym) macrobiotics

(a.)
Long-lived.
  

Macrobiotic refers to the macrobiota, a region’s living organisms (or flora and fauna) large enough to be seen with the naked eye. However, macro- comes from the Greek "makros" meaning not only "large" but also "long". So macrobiotic can also be taken to mean "long life." Thus, the idea with a macrobiotic diet is that it is for a long life, that is that the diet will lengthen life.
