A healthy diet is a healthy and balanced eating plan that promotes overall health. It should be complete with necessary substances like fluid, macronutrients, micronutrients, and adequate calories.

Healthy diets should contain whole grains, fruits and vegetables and may include a small amount of sweetened beverages and processed food.

To become healthy, a healthy diet and physical activity are needed. Living a healthy lifestyle has so many benefits especially in reducing the risk for illnesses like type 2 diabetes, obesity, heart disease, hypertension and cancer.


Below are the types of diet that people are using around the world:

The Paleo Diet

A paleo diet focuses on fish, vegetables, poultry, fruits, nuts, oils, sweet potatoes, eggs and meat ( meat should be grass-fed and not grain-fed).

Sugary, grains, dairy and processed foods are eliminated in a Paleo diet. The body will use fat as a fuel source if fewer amounts of carbohydrates are consumed.

The Blood Type Diet

This means giving the proper diet for each blood type. High protein foods are consumed by persons with type O blood. If planning for weight reduction, red meat, spinach, seafood and broccoli should be eaten while dairy should be skipped.

For type A, meat should be avoided and the diet should focus on fruits turkey and tofu while for those who want to lose weight, consuming soy, seafood and vegetables is advised.

The Vegan Diet

This diet eliminates meat and animal products, and focuses on veggies. To balance the diet for a lack of meat, vegans must find a way to integrate more sources of protein and vitamin B-12 into their diets.

The South Beach Diet

This diet aims to completely avoid carbohydrates but not to eliminate them altogether. The diet includes a selection of healthy fats, lean protein, as well as good carbs.
