Whether you're hoping to lose weight or simply maintain your health as you age, eating clean makes up a key component of a healthful lifestyle. Loading up your diet with minimally processed, whole foods -- such as whole grains, veggies, fruits, nuts, legumes, fatty fish and lean meats -- not only provides nutrients to support healthy cell function but also helps fight chronic disease. Cutting unhealthy foods out of your diet offers benefits because compounds found in unhealthy, processed foods can increase your disease risk.

Feel More Energetic

A healthful diet that properly nourishes your body helps you feel energetic and productive. Several nutrients, including the B-complex vitamins and iron, help your cells access fuel so that they can function properly. Eating clean also helps regulate your blood sugar, helping you avoid fatigue-inducing blood sugar spikes, which can occur after you eat processed carbohydrates, such as sweets or refined grains. The Michigan State University Extension recommends jump-starting your energy levels with a breakfast that includes fiber-rich whole grains, which provide energy that lasts you through to lunch.

Improve Cardiovascular Health

Eat clean to support long-term health -- a healthful diet helps lower your risk of cardiovascular disease. Fruits and vegetables, for example, come packed with vitamin C, a nutrient that helps maintain the strength of your blood vessels. A diet rich in fruits and veggies lowers coronary heart disease risk and also protects against stroke and high blood pressure. A clean diet rich in healthful fats -- the type found in nuts, avocados and olive oil -- lowers harmful cholesterol levels, which also fight cardiovascular disease. On the other hand, an unhealthy diet rich in saturated fat increases your blood cholesterol, which threatens your cardiovascular heath.

Prevent Cancer

Eat a clean diet, and you'll also help fight cancer growth. Following a diet rich in processed foods puts you at an increased risk of cancer, explains the Colorado State University Extension, and saturated fat, processed meat and fried foods all up your cancer risk. On the other hand, a clean diet, rich in fruits and veggies, boosts your intake of phytonutrients and antioxidants, which fight cancer growth. Colorado State highlights cruciferous veggies -- a family that includes broccoli and kale -- and tomatoes as especially beneficial.

Support Mental Health

A healthful diet not only benefits your physical well-being, but it supports your mental health. Some of the nutrients from your diet -- such as vitamin B-6, help make dopamine, a chemical involved in feelings of pleasure. Omega-3 fatty acids also support good mental health, while a deficiency can cause moodiness and depression. Limiting caffeine can also improve mental health -- the Norris Cotton Cancer Center notes that it can increase anxiety -- and not skipping meals can avoid stress headaches or stomachaches.
