In nutrition, the diet is essentially the sum total of all food ingested by an organism or individual within a specific time frame. For example, in the United States, the Dietary Guidelines for Americans (DGAs) are utilized to set the daily nutritional requirements of the average individual. On a nutritionally balanced diet, a person receives all of the nutrients necessary for good health, with at least a minimum amount of each of the major food groups. The major food groups are: carbohydrates, proteins, fats, fruits and vegetables.

To eat a healthy and balanced diet, it is important to pay attention to what you are putting into your body. As most dieticians and public health professionals will tell you, it is essential to include a variety of fruits and vegetables in your daily meals. This will ensure that your diet contains a sufficient amount of nutrients and that you are receiving a wide variety of vitamins and minerals. If you have been consuming a high fat diet or have been experiencing symptoms of heart disease, hypertension, or diabetes, your diet may need to be adjusted to include a variety of foods that are high in antioxidants and low in saturated fat.

There are three major food groups that should be the focus of your diet. These include carbohydrates, proteins and unsaturated fats. You should limit the amount of saturated fat you take in and substitute it with lean sources of protein such as poultry and fish, as well as low fat dairy products, such as yogurt and cottage cheese. If you do not eat a lot of red meat, you can increase the amount of chicken or fish you consume. Eggs should be eaten in moderation and should be limited to four eggs per week.

When creating your diet, it is also important to keep in mind how much of each nutrient and group of foods you should be including. For instance, if you are following a low fat, high fiber diet, you should make sure you are receiving plenty of fruits, vegetables, fiber-rich grains and legumes. Meats should be avoided as much as possible and should replace them with lower calorie alternatives, which will be more nutritious. Foods that are high in calories should be consumed in moderation as well. The rule of thumb is to have about half of your daily calorie intake in the form of carbohydrates, protein and unsaturated fats.

To improve your diet energy, many people turn to diet soft drinks. If you are on a low-calorie diet, one of the best options for replacing lost calorie is to drink diet soft drinks. There are several types of diet soft drinks that are low calorie and contain no sugar. One type of diet soft drink is diet orange, which is low in sugar and has zero calories. There are other types of diet drinks available that provide more than just diet energy, but they are typically low-calorie beverages.

As with most any dietary change, it is important to speak with your doctor before making any changes. Discuss your goals with your doctor and educate yourself on how your current diet may affect your long-term health. Most people find that the benefits from their dieting plan are well worth the time and effort, which often take place over several weeks or months. Changing your dieting habits regularly can help you maintain your weight loss and achieve optimal health. Be sure to talk to your doctor if you have any questions or concerns about your diet. Your doctor can give you the best advice on diets and can help you make the right choices for your lifestyle.
