Vitamins and minerals are needed in the body in small amounts to enable it to grow, develop and function.
A diet that has plenty of fresh fruits, vegetables, and unprocessed foods, should provide ample amount of vitamins and minerals.
A lot of the nutrients are lost through, processing, freezing, and canning.
Fruits and vegetables also lose some of their goodness through whilst left standing in the bowl

As we get older, our organs function less efficiently, absorption of essential nutrients and minerals become less.
It is, therefore, necessary to take in supplements to make up for the loss.
A few tips on to retain nutrients, vitamins, and minerals during cooking.
So now the question is how we get the most out of the food we eat.
The way we cook determines to a large extent, whether we preserve the nutrients or destroy them.
Cooking certainly affects the calorie content and its nutrients.
If we steam our vegetables, stir-fry, or cook only briefly in a microwave, we would retain the nutrients.
On the hand when we cook the process would allow the nutrients to seep into the water.
Also when we add, oils, fats, lard or butter to whatever we are cooking, the result is that we add more calories.
Similarly adding sugar or honey to whatever we are cooking constitutes adding more calories and carbohydrate value.
Soups, stews, and casseroles tend to preserve more of their nutritional values, as vitamins and minerals are retained in the broth.
Grilling your meat on a tray would allow the fat in the meat to drip off.
Finally, the shorter the cooking time the more nutrients will be retained, and the less fat and sugars added the better.
