Eating certain foods together with others can enhance the absorption of important nutrients in the body. One such combination is carrots with nuts, as vitamin A is absorbed in the presence of fat. In every meal that contains orange vegetables, you should also include nuts/quality oil to increase the absorption of this vitamin. Another important combination is tomato sauce with olive oil, as lycopene from cooked tomatoes is more available to the body and fat increases its absorption. Yellow cheese toast with red pepper also enhances the absorption of calcium from food as red peppers have a high amount of vitamin C which is important for calcium absorption. Vegetable omelette with spinach is another great combination as both spinach and vegetables contain an important antioxidant called lutein, which is important for eye health and the prevention of various eye diseases. The fat in egg yolk helps in the absorption of lutein.
