Because of the recent health crisis, people have realized that there’s a middle ground of eating. Accessibility, cost (no expensive specialty products for “approved” versions of breads, snacks, etc), and in some cases, a general realignment of some internal values have led people to adjust their diets.
The Flexitarian diet is flexible semi-vegetarianism that includes a moderate intake of animal products. The basic idea is you can get some of the benefits of vegetarianism without making a full commitment, thereby making it a more “acceptable”, lasting change for most people, and one that also happens to align with the 2015-2020 Dietary Guidelines.
