I know where you’re going with this and my comment isn’t to promote degenerating whole food plant based diets. The point is that a typical mixed standard diet of overeating is the cause of health issues. High fat/high carb mixed.
Veganism seems to be the most stringent of all the plant-based diets since it excludes all animal-related substances [3]. A whole-food plant-based diet (WFPBD) is another sort of vegan diet that has demonstrated substantial advancements in cardiovascular health, diabetes, and cancer types [4]. More specifically, WFPBD features many fruits and vegetables, whole grains, legumes, and natural soy products while eliminating animal products, processed carbs, fat, and sugar.
The long-term impacts of plant-based diets on health outcomes may be difficult to disentangle from plant-based diet-associated behaviors (e.g., regular exercise, avoidance of tobacco and alcohol). However, according to observational research, lower risks of coronary artery disease, obesity, arterial hypertension, type 2 diabetes, and some or perhaps all malignancies are linked with plant-based and vegetarian diets [5,6,7,8,9,10,11,12]. Randomized experiments have indicated that vegetarian and especially vegan diets have a positive influence on a variety of cardiovascular (CV) events [13].
