Meat has long been associated with heart disease, diabetes, and cancer. However, most studies are demographic studies or use food recall questionnaires. Both have limitations compared to clinical trials, and so, are lacking. For this reason, most governmental dietary guidelines include meat as a nutritious part of healthy eating, even with its undeserved bad reputation. Conversely, authorities have prompted the spread of vegetarianism and veganism, based on the assumption that non-meat diets provide more health benefits than diets that include meat. A recent study that included 90% of the world’s population showed a strong correlation between higher animal-based food consumption and longer lifespans. I will break the study down in today’s post for its strengths and weaknesses.
