Eating the right foods is great, however, if you are not processing it properly, much of its value is wasted. Make it a point to be more active in your daily routine. Adding a few steps here and there will add up over the week. This increased activity prompts your body to process more efficiently out of need. Also incorporate short walks after every meal to facilitate digestion.
Realize that some fruits or vegetables only provide starch-like nutrition. Bananas, for example, are very high in starch but do not necessarily provide the vitamins that humans require in their nutrition. Eating a single banana will not provide the correct amount of vitamins and thus a variety of other fruits are needed to get your total nutritional value.
Eat a balanced diet that includes fruits and vegetables if you are looking to improve your nutrition. You should find out your daily requirement of calories and base your diet on this. You should also avoid foods that are highly processed and contain a high amount of fat and sugar.
Nutritious meat means lean meat. Lean meat is extremely important in any meat eating home. Removing as much of the fat as possible will reduce your intake greatly. Speak to your butcher about the leanest cuts available. Ask for a high lean content on ground products also; perhaps even choosing your own cuts and asking to have it ground fresh.
