#nutrition But which is better – Vegan? Keto? Plant based? Low Carb? All of them, and none of them depending on what foods you choose. It’s about the types of food not the type of diet! It’s about high quality food vs low quality food. A vegan can eat potato chips and Krispy Kreme donuts, a Keto person could have bacon and cheese at every meal, a plant based diet can include french fries and highly processed breads/muffins and low carb people can choose highly processed sandwich meats to make wraps rather than pita or bread.
