Classes Of Food
There are six essential classes of food that we need for a healthy life.
Carbohydrates
It is essential and important for producing energy. And the brain will not function well without this fuel.
They are formed in foods like bread, tortilla, rice, pasta, oatmeal, and noodles; these are common sources of carbohydrates. Along with grains, some starchy vegetables are good sources of carbohydrates.
Whole wheat bread, grain pasta, and brown rice are good as fiber-rich carbohydrate intakes. Whole grains confirm enough fiber intake to help digestion.

Proteins
It is a main component of the cells of our body and helps for building and repairing tissues.
Some sources of protein for non-vegetarian are chicken, beef, pork, lamb, mutton, and fish. Dairy products, beans, and eggs are widely used protein sources.
Some high-protein sources for vegetarians are tofu, lentils, black beans, lima beans, chickpeas, almonds, cashews, pumpkin seed, spinach, avocado, broccoli, and Brussels sprouts.

Fat
We prefer cholesterol-free oil for cooking. Fat helps to absorb fat-soluble vitamins. Such vitamins include A, D, E and K. Omega-3 fatty acid-rich food is preferable. They help to develop the brain and bones.
Avocado, nuts, and seeds are rich sources of fat as well. We make sure of as little intake of saturated fats as possible. We avoid high-fat meats and full-fat dairy products.

Vitamins
Vitamin A contributes to the health of eyes and common sources of Vitamin A are yellow pumpkins, fruits, carrots, orange, leafy vegetables (like Spinach), and squash.
There are many different sources of Vitamin B like oatmeal, meat, fish, vegetables, avocados, brown rice, potatoes, eggs, dairy products, bananas, liver, and tree nuts.
Vitamin C may cause scurvy. Many fruits, vegetables, and liver are rich sources.
Vitamin D rich sources are fish, eggs, liver, and mushrooms. It is available from the sun exposure.
Vitamin E deficiencies are rare. Seeds, nuts, and vegetables are good sources of Vitamin E.
Vitamin K can be obtained from leafy green vegetables, liver, and egg yolks. Vitamin K deficiency may cause bleeding diathesis, gum bleeding, problematic blood clotting, and bleeding associated with the digestive system.

Minerals
Four important minerals for every individual’s needs are calcium, potassium, sodium and iron.
Calcium strengthens bones and teeth. Daily servings of milk, low-fat cheese, and yogurt ensure calcium intake.
Potassium helps in maintaining the volume of fluids in cells. It prevents high BP. Bananas, tomatoes, and potatoes are rich sources of potassium.
Iron-deficiency causes the production of fewer red blood cells, fatigue and anemia. Beef, chicken, salmon, leafy green vegetables, and eggs are good sources of iron.
Sodium helps to maintain a healthy environment for cells. It is better to keep sodium intake lower.

Water
Water is something that we do not keep track of as daily intake. It carries nutrients. Water removes waste products from the body.
Along with regular water, other sources of water are soup, watermelon, cucumber, and juicy fruits. It is not essential that we drink filtered or bottled water.
Filtering the tap water will limit the fluoride intake. We should drink it directly and not depends on the composition of minerals in the water.
