A healthy diet or balanced diet is a diet that contains the right amounts of all the food groups that exist.
Eating a wrong amounts of a food group, whether it be too much or too little, is called an “unhealthy diet” or an “imbalanced diet”. A healthy diet is one that includes more foods that come from plants and fewer convenience foods.
What is known about nutrition and diet keeps changing as more is learned. However, basic nutrition remains much the same. The best advice is to talk to a doctor or dietitian for personalized information based on an individual’s lifestyle, health, and food likes and dislikes.
Basic nutrition begins with a diet based on the major food groups that includes vegetables, whole grains, low-fat dairy products.
It should also contain lean protein such as beans, legumes, nuts and seeds plus healthy fats. A basic nutrition plan should include guidelines for how much food from each group to eat.
Foods should be those that can be found in local grocery stores instead of specialty and gourmet food stores. A basic food plan should be based on an individual’s budget, lifestyle and (healthy) preferences.
