Fat is not your enemy. Cutting fat out of your diet or eating very little fat can be harmful to you. Eat fat as part of a well-balanced diet. There is no need to eat a carton of ice cream in one sitting, but a bowl is fine. Everything in moderation.
A good nutrition tip is to eat darker colored vegetables. Darker colored vegetables tend to offer the best nutrition. A good example of a darker vegetable would be something like broccoli or spinach. Avoid lighter colored vegetables such as celery and iceberg lettuce because they offer very little in terms of nutrition.
