There are countless benefits of eating healthy, and while it can be a challenge to change your lifestyle, it will be worth it in the end!
What Defines Eating Healthy?
Eating healthy should typically include a balanced intake of carbohydrates, proteins, and fats. The definition of eating healthy can be subjective, depending on who you’re listening to. However, most experts agree that eating healthy means eating with a raised awareness of the food you are ingesting, and of what effects it will have on your body. As modern diets have become increasingly processed, many people no longer consume the wide spectrum of vitamins and minerals needed for optimum health. 
Benefits of Eating Healthy
The most important benefits of eating healthy include its effects on your immune system, weight loss, heart health, metabolism, and longevity.
Prevents Nutrient Deficiencies
A well-balanced diet is considered to be one that not only provides adequate energy for the day but also delivers the nutrients your body needs to maintain health and prevent illness. Many people suffer deficiencies in vitamins A, B, C, and E, as well as minerals like zinc and magnesium. A healthy diet also promotes a healthy body weight, which can prevent many diseases that occur in middle-aged and elderly populations. 
A diet rich in whole grains and vegetables, with low dairy and low fat, has been shown to help prevent heart disease by reducing high blood pressure and cholesterol. It also helps in preventing diabetes.
A high-calcium diet, with adequate sources of vitamin D and magnesium, is essential for strong bones and teeth and helps slow the bone deterioration that occurs with age.
A healthy diet especially rich in fiber is also an effective way of reducing obesity. You can add vegetables and fruits that are high in fiber and lose the excess pounds easily.
Of course, when your body is healthier, you live longer. In combination with daily exercise, healthy, low-calorie diets help people extend both their lifespans and their quality of life, as well as avoiding higher healthcare costs as they age. 
Lowers Stress Levels
Healthy eating habits not only help you live longer and avoid increasing health concerns, but they also make you feel better. A protein-rich diet reduces stress by lowering cortisol levels. Foods rich in omega-3 fatty acids also help lower the risk of depression and regulate moods. Finally, a proper nutrient intake will also help increase focus and productivity, thanks to increased oxygen flow, energy, and clarity. 
Note: There are no side effects to eating healthy. However, as a result of the wealth of conflicting health information available to consumers, it is important to check with a medical professional before making major changes to your diet and nutritional intake.
