Healthy diets are defined as eating less fat, more fiber, and increasing protein and carbohydrates while consuming small amounts of saturated fat. A good healthy diet is also one which helps sustain or enhance general health. A healthy diet supplies the body with vital nutrition: sufficient calories, fluids, vitamins, minerals, and adequate nutrients. A good diet should be balanced and include a variety of food types.
Generally, healthy diets are low in saturated fats and increase the fiber intake in the diet, mainly by replacing hydrogenated oils and trans fats with mono-unsaturated fats from fruits, vegetables, legumes, seeds, and nuts. They decrease the intake of sodium, increase the fiber intake and sodium reduction, while balancing the nutrient content. These diets are low in sodium, salt, and sugar and high in potassium, magnesium, and potassium. The intake of adequate amounts of calcium is promoted by foods such as whole grains, beans, green vegetables, fish, and fruits and vegetables. Low consumption of alcohol is recommended.
Eating healthy diets is important for human health because eating less fat, more fiber, and increasing the consumption of potassium are effective ways to reduce the risk for heart diseases and certain cancers. Heart diseases are the commonest causes of death around the globe. These diseases are mostly associated with poor dietary habits; therefore, these diets help lower the risk for coronary artery disease and heart diseases. Moreover, these diets promote weight loss and improved physical performance, especially in athletes. A healthy diet can thus reduce the risk for osteoporosis. A diet rich in fruits, vegetables, legumes, whole grain cereals, fish, eggs, and nuts is highly advisable for maintaining or improving health.
With the recognition of the importance of healthy diets in human health, several complementary treatments have been developed over time, all of which aim at improving the nutritional quality of the diet and at decreasing the risk of acquiring cardiovascular diseases and certain cancers. Several nutritional supplements are available in the market nowadays, such as vitamins, minerals, herbal remedies, and probiotics. The most popular ones are usually recommended by doctors and endorsed by celebrities. The availability of fop labels, which feature unbiased information about various supplements, makes it easier for people to choose. These fop labels even provide information on the origin of ingredients.
The development of sustainable food systems is the foundation of sustainable diets. The production of food in sustainable food systems ensures that the environmental impact of conventional farming is reduced while the productivity of farmers increases. This process is promoted by local organizations, governments, communities, and individuals. The increased consumption of animal-based foods is a major contributor towards global warming. Many farmers adopt the biodynamic production of coffee, olive oil, sheep wool, milk, meat, vegetables, fruits, etc., which significantly reduce the consumption of meat and thus contribute to sustainable eating.
Sustainable diets help improve the intake of fruits and vegetables, which are the staple diet of millions of people, especially children. The consumption of fruits and vegetables improves the absorption of dietary fiber and prevents many diseases, such as cancer, heart diseases, osteoporosis, diabetes, etc. These diets help improve household incomes by reducing household expenses on food. The reduction in food expenses leads to more consumption of fruits and vegetables in the diet, which leads to further reductions in household expenses. Over time, when economies improve, household incomes will increase again, and consumption of unhealthy foods will decrease.

Some people argue that diets can be healthy if only people eat a wide variety of foods. However, research has found that the intake of a wide variety of foods results in decreased consumption of nutrients-such as vitamins, minerals, and antioxidants-and increases intake of fat-which results in increased body weight. Another argument against diets is that nutrients can be supplied from supplementation. Vitamins and minerals are found in many naturally-occurring foods, such as whole grains, fruits, vegetables, etc., whereas fat is obtained from eating too much red meat, excessive fats found in some meats, etc. Thus, it is argued that nutrient loss is not caused by eating healthy but by eating foods that are high in calories, such as junk food, fast food, processed foods, etc.
