In this video, Chef Caleb breaks down the effects of major food groups on the body, starting with fruits (nutrient-dense whole fruits are excellent due to fiber slowing sugar absorption, unlike juices that spike blood sugar like soda), vegetables (near-perfect low-calorie, high-fiber powerhouses for gut health, vitamins, and satiety with minimal downsides), grains (whole grains provide steady energy and health benefits, while refined versions act like sugar and hinder fullness), dairy (great source of protein, calcium, and probiotics for those who tolerate it, but problematic for the lactose-intolerant and when heavily sweetened), and continuing into meat (highly bioavailable complete proteins and nutrients), fish/seafood, eggs, legumes, nuts/seeds, and oils/fats, with practical advice throughout on choosing whole, minimally processed forms for optimal health.
