1. One of the most important principles of good eating is proper chewing. You should chew till the food becomes liquid. That how our bodies can assimilate solid food easily. Proper chewing also results in less food consumed overall, as you’re probably will get tired of eating before you get too full.

2. Food must be tasty! Tasteless food is badly assimilated and rarely eaten in enough quantities. If you can find ways to make healthy food taste better (for example, by adding more spices or some low-fat sauces), you will be more likely to enjoy it more often and in quantities large enough to satisfy both your hunger and your nutritional requirements.

3. Of all the nutrition mistakes you might make, skipping breakfast is the biggest. Skipping breakfast can leave you drained for the rest of the day. In comparison, a high-energy breakfast sets the stage for a high-energy day. Breakfast doesn't have to be a sit-down, cooked meal. It can be a substantial snack on the way to work or school. Examples for quick, healthy breakfasts include smoothies prepared with low-fat milk or yogurt and fresh or frozen fruit, or whole grain cereal topped with low-fat yogurt and fresh fruit.

4. Having dinner less than two hours before going to sleep is not good.

5. Fruits, fresh and boiled vegetables and nuts are accepted to be the best food.

6. For better results, make sure that you vary your food day to day. This will provide you with a better balance of nutrients and prevent you from ingesting an excess of one vitamin while having a deficiency of another one.

7. If you cook in large quantities, freeze the leftovers rather than leaving them in the fridge for days.

8. Avoid fried food. The less we cook our meal, the tastier (and healthier) it is.

9. Dietitians advice not to overfill ourselves with food. It is better to eat several times a day (and to do so slowly, chewing properly), than consuming 1-2 large meals a day.

10. The recommended intake is at least 2 1/2 cups of vegetables per day. “Many busy people rarely eat that much in a week,” says Nancy Clark, MS, RD, author of Nancy Clark's Sports Nutrition Guidebook. People who have a hard time eating enough veggies should eat large portions when they do eat vegetables---a big pile rather than a standard serving. That can be as much as 2 cups in one sitting.
