6] Minerals

A] Calcium, which is required for the formation of healthy bones and teeth, is also needed for blood clotting and proper functioning of the heart .It is found in milk and milk products, green vegetables, broccoli, cabbage, kale, tofu, sardines and salmon.

B] Phosphorus works with calcium to promote the formation of teeth and bones, maintain acid base balance in the body. Found in Milk and milk products, grains, nuts and legumes, lean meats

C] Sodium – It regulates the fluids in the body and thus regulates the blood pressure. It is also essential for the nerve function and energy production .It is present in Table salt and most processed foods and hence care should be taken when the diet has too much processed foods as higher sodium levels will lead to increase in blood pressure. Other sources include baking soda, monosodium glutamate (MSG), various seasonings, additives, condiments, meat, fish, poultry, dairy foods, eggs, smoked meats, olives, and pickled foods.

A diet rich in leafy vegetables, dried beans, beaten rice, jaggery, dried fruits, nuts, lentils, meats, eggs, dark green leafy vegetables, whole grains and enriched food products is a sure way to keep anemia at bay.

F] Zinc- It promotes the tissue growth and also helps prevent anemia. It is found in Eggs, milk, meat, seafood, and liver, whole-grains.

G] Iodine- It is essential for the proper functioning of thyroid gland and can be included in the diet by using iodized salt and milk.

There are quite a few other minerals like Magnesium, chromium which are needed a for energy metabolism. They can be found in whole grains, breads, vegetable oils, milk and cheese.

No single food can meet the total nutritional requirement for a day, hence the meal should be planned in such a way that at least a few foods from each food group are included and distributed in the menu.

Please note that Nutrition in itself is a vast topic and it has been consolidated here to provide the details in a nutshell.

In my next article, I will be talking about how to make food more interesting with the things we learnt from above.
