Depending on whom you ask, “healthy eating” may take any number of forms. It seems that everyone, including healthcare professionals, wellness influencers, coworkers, and family members, has an opinion on the healthiest way to eat. Plus, nutrition articles that you read online can be downright confusing with their contradictory — and often unfounded — suggestions and rules. This doesn’t make it easy if you simply want to eat in a healthy way that works for you. The truth is, healthy eating doesn’t have to be complicated. It’s entirely possible to nourish your body while enjoying the foods you love. After all, food is meant to be enjoyed — not feared, counted, weighed, and tracked. This article cuts through the noise to explain what healthy eating means and how to make it work for you. Why does eating healthy matter? Before we dive into what healthy eating means, it’s important to explain why it matters. First, food is what fuels you and delivers the calories and nutrients your body needs to function. If your diet is deficient in calories or one or more nutrients, your health may suffer. Likewise, if you eat too many calories, you may experience weight gain. People with obesity have a significantly increased risk of illnesses like type 2 diabetes, obstructive sleep apnea, and heart, liver, and kidney disease (1

While diets rich in ultra-processed foods are linked to increased mortality and a greater risk of conditions like cancer and heart disease, diets comprising mostly whole, nutrient-dense foods are associated with increased longevity and disease protection (3

Trusted Source, 9Trusted Source). What’s more, if your current diet is high in ultra-processed foods and beverages like fast food, soda, and sugary cereals but low in whole foods like vegetables, nuts, and fish, you’re likely not eating enough of certain nutrients, which may negatively affect your overall health (10

Now that you know why healthy eating is important, let’s cover some nutrition basics. When you conceptualize healthy eating, your first thought might be about calories. Even though calories are important, your primary concern should be nutrients. That’s because nutrients, including protein, carbs, fat, vitamins, and minerals, are what your body needs to thrive. “Nutrient density” refers to the amount of nutrients in food in relation to the calories it provides (11
Trusted Source). All foods contain calories, but not all foods are nutrient-dense. For example, a candy bar or a box of mac and cheese may be incredibly high in calories but lack vitamins, minerals, protein, and fiber. Similarly, foods marketed as “diet-friendly” or “low calorie” may be very low in calories but lack nutrients. For example, egg whites are much lower in calories and fat than whole eggs. However, an egg white provides 1% or less of the Daily Value (DV) for iron, phosphorus, zinc, choline, and vitamins A and B12, while a whole egg packs 5–21% of the DV for these nutrients (12
Trusted Source, 13Trusted Source). That’s because of the nutritious, high fat yolk that eggs contain. Plus, although some nutrient-dense foods, such as numerous fruits and veggies, are low in calories, many — like nuts, full fat yogurt, egg yolks, avocado, and fatty fish — are high in calories. That’s perfectly OK! Just because food is high in calories doesn’t mean that it’s bad for you. By the same token, just because food is low in calories doesn’t make it a healthy choice. If your food choices are based solely on calories, you’re missing the point of healthy eating. As a general rule, try to mostly eat foods that are high in nutrients like protein, fiber, healthy fats, vitamins, and minerals. These foods include veggies, fruits, nuts, seeds, beans, fatty fish, and eggs. 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 (14
Trusted Source, 15Trusted Source, 16Trusted Source, 17Trusted Source). Still, eating a variety of foods may be difficult if you’re a picky eater. If that’s the case, try to introduce new foods one at a time. If you don’t eat many vegetables, start by adding a favorite veggie to one or two meals per day and build from there. Although you may not enjoy trying new foods, research shows that the more you’re exposed to a food, the greater your chances of growing accustomed to it (18
