Between the gluten sensitivity, low-carb diets, and paleo, grains, in general, have fallen out of favor over the last decade or so. The original U.S. Department of Agriculture guidance published in 1992 made their foundation of the food pyramid, with 6-11 recommended servings per day.  The more recent USDA guidance for MyPlate reduces the servings of grains and advises that half of them should be whole grains.

All-cause mortality studies make a much sharper division between whole grains and refined grains. Refined grains, like white bread, white rice, or refined pasta, are practically the baseline of the developed world diet. Eating more or less refined grains generally doesn’t affect longevity, positively or negatively Food groups and risk of all-cause mortality: a systematic review and meta-analysis of prospective studies.1

The longevity benefits of whole grains, in comparison, look unlimited. Each serving (about 1 ounce or 30 grams dry) of whole-grain reduced all-cause mortality by about 8%, and the benefits of whole grains at least up to 8 servings, with little sign of decreasing benefit Whole grain consumption and risk of cardiovascular disease, cancer, and all-cause and cause-specific mortality: a systematic review and dose-response meta-analysis of prospective studies. 2

When going through the details of the various types of food with whole grains, like dark bread, whole-grain breakfast cereals, and other grains (bulgar, kasha, and couscous, etc.), they all show a dose-related benefit. There doesn’t seem to be any particular category that was better or worse than the others.

Eat over 100 grams (dry weight) of whole grains, and give your diet a solid foundation for longevity!
