A healthy diet is one that helps maintain or improve overall health. A healthy diet provides the body with essential nutrition: fluid, macronutrients, micronutrients, and adequate calories. A healthy diet may contain fruits, vegetables, and whole grains, and includes little to no processed food and sweetened beverages. Maintain a healthy weight by eating roughly the same number of calories that your body is using.
Limit intake of fats. Not more than 30% of the total calories should come from fats. Prefer unsaturated fats to saturated fats. Avoid trans fats.
Eat at least 400 grams of fruits and vegetables per day (potatoes, sweet potatoes, cassava and other starchy roots do not count). A healthy diet also contains legumes (e.g. lentils, beans), whole grains and nuts.
Limit the intake of simple sugars to less than 10% of calorie (below 5% of calories or 25 grams may be even better).
Limit salt / sodium from all sources and ensure that salt is iodized. Less than 5 grams of salt per day can reduce the risk of cardiovascular disease.
