Food is any material taken from a living organism to provide dietary support in the form of nutrients needed to maintain an organism’s health. In the human diet, food mainly consists of carbohydrates, protein, fat, vitamins, minerals and water. The major categories of food are carbohydrate-containing foods like breads, rice, pasta, cereals, potatoes, and fruits; protein-containing foods like meat, poultry, fish and eggs; vitamins and mineral-rich foods like whole milk, butter, tomatoes, peppers, and green vegetables; and fat-containing foods like processed oils and fats. Some of the major food groups are whole grains, dairy products (cheese, yoghurt), vegetables (red meat, beans, legumes), fruits (apples, banana, mangoes, melons), legumes (peas, lentils), and nuts (peanuts, almonds, cashews). Food can also be categorized according to whether they are vegetable-based, protein-based, or fat-based.
The basic function of food is to supply nutrients to an individual so that he/she can live a healthy life. It is important to choose the right kinds of food, which can meet your daily requirements. For example, it is not recommended to eat large amounts of junk food, as it would not only cause you to gain weight, but also leave you with a feeling of being hungry constantly. If you are interested in eating nutritious foods, you should choose fresh vegetables and fruits over canned or packaged ones, raw or steamed foods, cooked or fried foods, processed foods, sugar substitutes, salt, artificial sweeteners, as well as alcoholic beverages. To improve your immune system, you should also include foods rich in antioxidants like berries, garlic, green tea, cranberries, kiwi fruit, raspberries, strawberries, plums, asparagus, pineapples, prunes, raisins, blueberries, cherries, lemon drops, passion fruit, kiwi fruit, camu, lychee fruit, passion fruit, mangosteen, acai berry, garcinia cambogia, aloe vera, chaste tree leaf extract, ginger, cloves, nutmeg, allantoin, sarsaparilla, gingko biloba, licorice root, hawthorn berry, and green tea.
Start simple: It is better for you to start simple when it comes to eating healthy and nutritious food. For example, try eating one kind of vegetable every day instead of three or more kinds each week. Try to include more fruits as well, instead of just a few vegetables. These ideas will definitely help you improve your health in a fun way.
