The largest study in history of those eating plant-based diets recently compared the nutrient profiles of about 30,000 non-vegetarians to 20,000 vegetarians and about 5,000 vegans, flexitarians and no meat except fish eaters. Allowing us to finally put to rest the perennial question, do vegetarians get enough protein? The average requirement is 42 grams of protein a day. Non-vegetarians get way more than they need, and so does everyone else. On average, vegetarians and vegans get 70% more protein than they need every day. Surprising that there's so much fuss about protein in this country, when less than 3% of adults don't make the cut. There's only folks on extreme calorie-restricted diets who just aren't eating enough food period. But 97% of Americans get enough protein. There is a nutrient though, for which 97% of Americans are deficient. Now that's a problem nutrient. That's something we really have to work on. Less than 3% of Americans get even the recommended minimum adequate intake of fiber. So the question isn't where do you get your protein, but where do you get your fiber? We only get about 15 grams a day. The minimum daily requirement is 31.5. So we get less than half the minimum. If you break it down by age and gender, after studying the diets of 12,761 Americans, the percentage of men between ages 14 and 50 getting the minimum adequate intake zero. This deficit is stunning. In that dietary fiber has been protectively associated with the risk of diabetes, metabolic syndrome, cardiovascular disease, obesity, and various cancers, as well as high cholesterol, blood pressure, and blood sugars. Therefore it is not surprising that fibers now listed as a nutrient of concern in the dietary guidelines. Protein is not. One problem is that most people have no idea what's in their food. More than half of Americans think steak is a significant fiber source. By definition, fiber is only found in plants. There's no fiber in meat, dairy, or eggs, and little or no fiber in junk food. Therein lies the problem. Americans should be eating more beans, vegetables, fruits, whole grains, how are we doing on that? While 96% of Americans don't eat the recommended minimum daily intake of beans. 96% don't eat the measly minimum for greens. 99% don't get enough whole grains. Look at these numbers. Nearly the entire U.S. population fails to eat enough whole plant foods and it's not getting any better. A lack of progress that's disappointing. Even semi-vegetarians though make the minimum for fiber. And those eating completely plant-based diets triple the average American intake. Now when closing the fiber gap, you want to do it gradually, no more than about 5 extra grams of fiber a day each week until you can kind of work your way up, but it's worth it. Plant-arived diets tend to contribute significantly less fat, saturated fat cholesterol, food-borne pathogens. While at the same time offering more fiber, folic, vitamin C, phytochemicals, all essential factors for disease, prevention, and optimal health and well-being. And the more plant foods, the better. Whole plant foods, the better. If you compare the nutritional quality of vegan versus vegetarian, semi-vegetarian, pesco-vegetarian, on-niverse diets, traditional, healthy diet indexing systems like compliance with dietary guidelines consistently indicate the most plant-based diet as the most healthy one.
