Having a healthy diet is important for ensuring that your body gets all the vitamins and minerals it needs. It also helps you control your weight and fight fatigue. It can also help you manage your moods. Good nutrition also includes foods that are low in calories. Some foods are high in fiber, which helps you feel full.

Another good source of nutrition is lean meat. Lean meat is less fat, and also has fewer calories. It is also a good source of protein. You can also get your protein from poultry, but you will get fewer calories from poultry. Whole grains are a good source of vitamins and minerals, and keep your bones strong. Whole grains are also high in calcium.

Fruits and vegetables also contain vitamin C, which is good for your eyes. Bell peppers contain the most vitamin C per calorie. You should also make sure that you are getting adequate amounts of folate. Low folate levels are linked to depression, neural tube abnormalities and miscarriage. You should consume 600 micrograms of folate a day to reduce these risks.

Nut oils, like walnut oil, are a good source of healthy fats. They contain fatty acids and plant sterols, which help to lower cholesterol. However, nut oils are high in calories, and they do not contain the fiber found in whole nuts. They also become bitter if you heat them too much. You should avoid nut oils if you are on a diet. Instead, you can eat foods that are high in healthy fats, such as avocados and olive oil.
