The production of meatless hamburgers requires 99% less water, 93% less land, 90% less greenhouse gas emissions, almost 50% less energy. And besides, satiate more.
This is what a recent 2018 study suggests that compared the physiological responses of men after eating meat and plant-based hamburgers.
All men pointed out in the study that they felt fuller after eating the hamburger of plant origin. The researchers asked a group of participants to eat both meals on separate days. The group consisted of 60 men, 20 healthy, 20 obese, 20 with type 2 diabetes, to all of whom their physiological responses were recorded after each meal.
It seems that vegan foods produce higher levels of beneficial gastrointestinal hormones that are involved in the "regulation of glucose metabolism, energy homeostasis, satiety and weight control," according to the authors.
The reason is not very well known, but, among other factors, it could be due to the high fiber content of the vegan burger.
The study had several limitations, namely that it examined a small test sample of only men, and that it only examined physiological responses after two specific meals, not a usual diet. Still, the researchers suggested that vegetarian hamburger-based diets could be useful in treatments for diabetes and obesity.
Vegan burgers are increasingly fashionable, and some are reaching a degree of similarity with their original counterparts that is amazing: Impossible Foods, for example, has managed to take another step to compete with Beyond Meat in the boom of vegan burgers , because the United States Food and Drug Administration (FDA) has approved the use of soy leghemoglobin as an additive.
