Why should we include both animal and plant foods in our diet?

Man belongs to omnivorous organisms, therefore it is important for us to receive both animal and plant food. Animal foods are high in protein, essential fats and fat-soluble vitamins, as well as iron and other important trace minerals. Plant food contains water-soluble vitamins – C, B, as well as fiber, which contributes to proper, high-quality digestion. Fruits contain pectin, which is also essential for life. Dairy products are a source of calcium and protein.
