It has been argued that vegans and vegetarians live longer on average due to their overall healthier lifestyles. The argument goes: vegans and vegetarians drink less alcohol, smoke less, eat less junk food and workout more. Some believe that vegan and vegetarian lifestyles are not inherently healthier, but rather, that vegans and vegetarians partake in more healthy habitats generally. This difference in lifestyle habits is thought to explain the difference in vegan/ vegetarian and meat-eater lifespan.
Some studies, like this one from the Translational Psychiatry, have found that the plant based foods which make constitute vegan and vegetarian diets nurtures metabolism and curbs inflammation. These results were not only observed in healthy study participants, but also in participants that were obese, and those that had type-2 diabetes.
What Are the Benefits to Vegan and Vegetarian Diets?
Plant based diets of vegans and vegetarians are associated weight loss and metabolic improvements. Metabolic improvements from plant based foods (that are good sources of fiber and are low in saturated fats and oils) are due to the higher concentrations of dietary fiber (which helps regulate human digestion) and healthier sources of fats. High amounts of saturated fat can cause cholesterol to accumulate in your blood vessels. Saturated fats raise your Low-density lipoprotein cholesterol. High Low-density lipoprotein cholesterol increases your risk for heart disease and stroke. Healthy fats and fiber-rich foods may make weight loss more feasible.
Vegan and vegetarian diets reduce inflammation by avoiding cholesterol and by containing inflammation fighting agents, such as phytochemicals and other antioxidants. Antioxidants protect your body’s cells from free radicals- which can cause molecular oxidation in the body. Phytochemicals help stop the formation of potential cancer-causing substances and may decrease inflammation.
