Consume fruits and vegetables Experts say you should consume at least one dark green and one orange per day. Examples of dark green vegetables include spinach, kale, and broccoli.
Should steam, bake or boil vegetables. Limit or avoid foods that are thoroughly fried. Whole fruits and vegetables are a better choice than their juices, as they provide more nutrients and fiber. They also fill you up for longer, which can prevent overeating.
Consume grains Nutritionists recommend eating whole grains in half of your cereal servings. Choose from a variety of grains, including quinoa, oats, brown rice, and barley. Whole-grain pasta, oatmeal, and bread are better than those made with refined grains.

Meat and alternatives Make sure you are eating alternatives, such as tofu, lentils and beans regularly. Eat fish at least twice a week. Be careful with certain types of fish exposed to mercury like tuna. Choose lean meats, such as chicken.
Instead of frying, try roasting, baking, or boiling. If you're eating processed or prepackaged meat, choose low-salt and low-fat varieties. Limit your overall intake of processed meats because you can increase your risk of cancer if eaten regularly.
When eating carbohydrates, choose unrefined carbs, such as whole grains, that are high in fiber and release energy slowly, so you feel full for longer.
Limit saturated fat and avoid trans fat as much as possible. You should consume no more than 10 percent of your total calories from saturated fat. Vegetable oils, fish and nuts are the best sources.
Make sure to provide plenty of fiber. When eating fruits and vegetables, eat a variety of colors. If you're not a milk drinker, make sure you're consuming enough calcium.
If your main concern is knowing how much food you should eat, you still have to know about their caloric value. With high-calorie foods, the quantity will be less, while with lower-calorie foods, you can eat more.

5. Some related studies

In some people, strict restriction of daily calorie intake may prolong life overall.
Animal studies show that some species seem to live longer if they are partially starved, but these are considered "poor quality" studies, and it is unlikely that calorie restriction will have any effect. the same for humans.
However, scientists from Louisiana State University in Baton Rouge explained in the journal Nature, in 2012, that the two main factors that influence longevity are good genes and a healthy, balanced diet .
Researchers believe that many previous studies were wrong when they compared a high-calorie diet with a very low-calorie diet.
A study published in the American Journal of Clinical Nutrition in 2013, found that if you eat a serving of fruits and vegetables "5 days a week", you are likely to live longer
2016, The researchers concluded that the effect of diet on aging "is not simply the result of reduced calorie intake, but is also determined by diet composition."
