People consume food in many ways and at many different times throughout the day. When a person is hungry, they eat food, whether its from their diet or food given by someone else. When we are sad or frustrated, we eat food to comfort us. Food can be divided into several categories, depending on how it is consumed and how it affects the body.

Diet is the term used to describe the eating pattern and the variety of food that meets this pattern. The most common food groups are carbohydrates, protein, fat, and vegetables. Healthy eating pattern is related to eating nutrient-dense foods from all food groups. Generally, food is categorized into three major food groups: carbohydrates, protein and vegetables. In general, healthy eating pattern involves consuming five to six servings of vegetables per day, four to five servings of carbohydrates and one to two servings of protein per day.

Cereals, breads, pastries, crackers, rice cakes, wafers, cookies, potato chips, and bread rolls are some examples of carbohydrate-rich foods. These products contain mostly simple carbohydrates, which are easily metabolized in the body. The carbohydrates found in these foods are quickly absorbed and used by the body for energy production. The sugar found in high-fibered cereals and breads passes rapidly through the blood-clotting system, causing a sharp drop in blood sugar levels.

Vegetables and fruits constitute the rest of the food group. Fruits consist of water, complex carbohydrates, and protein. Some examples of complex carbohydrates are beans, peas, nuts, and whole grains like wheat, oats, corn, rice, etc. Carrots, spinach, squash, cabbage, kale, lettuce, cabbage, and avocados have high fiber content. A glass of whole milk produces more nutrients than a glass of ice-cream or yogurt.

Milk is a source of proteins. It contains low fat, but contains a high quantity of proteins. High-fiber grains like oats and barley contain the adequate amounts of protein that are needed for a strong immune system. The vitamins, minerals, and minerals found in most whole grains and dairy products are very important for the overall health of the body and are lacking in most modern diets.

Rice is the best choice for a healthy diet. The grain, which has been used for making porridge and other baked products, is rich in dietary fiber. It is rich in iron, phosphorous, and B vitamins. Brown rice is recommended because it has a longer lifespan than white rice. Other whole grain foods that are rich in fiber and yet are easy on the digestive system are oatmeal, walnuts, sweet potatoes, bran, barley, millet, and brown rice.
