In addition to their “US-Style” or omnivorous eating pattern, the new 2015 Dietary Guidelines recommend a Vegetarian Pattern, and even a Vegan Pattern of eating. They note that these patterns are higher in calcium (even though they contain no dairy food) and fiber than the US-Style Pattern:
To achieve these plant-based eating patterns, they say to simply remove animal foods and replace them with beans, nuts and seeds, and whole grains.
Based on a comparison of the food choices of vegetarians to nonvegetarians in NHANES, amounts of soy products (particularly tofu and other processed soy products), legumes, nuts and seeds, and whole grains were increased, and meat, poultry, and seafood were eliminated. … This Pattern can be vegan if all dairy choices are comprised of fortified soy beverages (soymilk) or other plant-based dairy substitutes.
You don’t have to eat soy. Soy beans are just beans. You can eat any other bean, pea, or legume in their place.
Good for them! Good for us!
