Nutrient density
When you conceptualize healthy eating, your first thought might be about calories. Even though calories are important, your primary concern should be nutrients.
Diet diversity
Another component of healthy eating is dietary diversity, meaning eating a variety of foods.
Following a diet that’s rich in different kinds of food supports your gut bacteria, promotes a healthy body weight, and protects against chronic disease.
Macronutrient ratios
Macronutrients — the main nutrients you get from food — are carbs, fat, and protein. (Fiber is considered a type of carb.)
Generally, your meals and snacks should be balanced between the three. In particular, adding protein and fat to fiber-rich carb sources makes dishes more filling and tasty.
