Food is one of the basic need of our life, without which we can’t survive. However, there are some instances where people claimed that they survived without food for many years. But that’s a rare case scenario.

Here in this article, you will get every single piece of information you ever wanted to know about Food, Nutrition, Healthy Diet, etc.

Food

What Is Food?

Food is any substance consumed to support the body’s diet. This usually comes from plants or animals and contains important nutrients such as carbohydrates, fats, proteins, vitamins or minerals. This substance is absorbed by the body and absorbed by the body’s cells to provide energy, life or stimulate growth.

Types Of Food

Basically there 5 major food groups/types, they are as follows:

  1. Vegetables
  2. Protein
  3. Fruits
  4. Grains
  5. Dairy

Now we will understand these groups one by one.

1. Vegetables

Vegetables are those types of food which we get from plants that are consumed by humans or animals. The original meaning is still used and applied to the plant as a whole to refer to all edible plant substances, including flowers, fruit, stems, leaves, roots and seeds. An alternative definition of the term vegetable is applied rather arbitrarily, often from culinary and cultural traditions. Exceptions can be food from certain plants, which are fruits, flowers, nuts and cereals, but also some fruits such as tomatoes and zucchini, flowers such as broccoli and seeds as pulses.

There are different kinds of vegetables. Some common vegetables are:

  • Carrot
  • Broccoli
  • Asparagus
  • Cauliflower
  • Corn
  • Cucumber
  • Eggplant
  • Green pepper
  • Lettuce
  • Mushrooms
  • Onion
  • Potato
  • Pumpkin

  • Chilli
  • Garlic
  • Basil
  • Coriander
  • Parsley
  • Rosemary
  • Oregano
  • Cinnamon
  • Saffron
  • Green bean
  • Bean
  • Chickpea

2. Protein

Protein is an important nutrient for the human body. They are one of the building blocks of the body’s tissues and can also function as a fuel source. Protein produces energy as much as carbohydrates: 4 kcal (17 kJ) per gram; Conversely, lipids produce 9 kcal (37 kJ) per gram. The most important aspect and characteristic of proteins from a nutritional standpoint is the composition of amino acids.

We can get protein from lean meats and poultry, fish, eggs, tofu, nuts and seeds, legumes/beans.

3. Fruits

In common terms, “fruit” usually means seed structure associated with sweet or sour plants and can be eaten raw, such as mangos, bananas, grapes, oranges and strawberries. On the other hand, “fruit” in botanical use contains many structures which are not commonly referred to as “fruits”, such as beans, corn beans, tomatoes and whole grains. The spore-producing mushroom part is also called the fruit body.

Y: Yellow Passion Fruit, Yunnan Hackberry, Yangmei
Z: Zig Zag Vine fruit, Zinfandel Grapes, Zuchinni

4. Grains

Grains are small, hard, dry seeds with or without skin or fruit intended for human or animal consumption. After harvest, dried grains are more durable than other staple foods such as starch (plantains, bread, etc.) and tubers (sweet potatoes, cassava, etc.). Because of this durability, the grain is very suitable for industrial agriculture because it can be mechanically harvested, transported by train or by boat, stored in silos for a long time and ground for flour or pressed for oil. Therefore, there is a large global commodity market for corn, rice, soybeans, wheat, and other cereals, but not tubers, vegetables or other crops.

Types Of Grains

  • Whole Grains: These items are in their overall form or ground into flour, keeping all parts of the seed (bran, embryo and endosperm). Compared to other cereals, seeds are a better source of fibre and other important nutrients such as B vitamins, iron, folic acid, selenium, potassium and magnesium. Whole grains are single foods such as brown rice and popcorn or ingredients for products such as buckwheat in pancakes or whole wheat flour in bread.
  • Refined Grains: Processed grains are soil for removing embryos and bran, giving them a finer texture and longer shelf life. The refining process also removes many nutrients including fibre. Processed grains include white flour, white rice and white bread. Lots of bread, cereals, biscuits, desserts and cakes made from processed grains.
  • Enriched Grains: Enriched means replacing some of the nutrients lost during processing. Some enriched grains have replaced B vitamins lost during grinding. Strengthening means adding nutrients that do not occur naturally in food. Most processed grains are enriched with vitamins and other minerals such as folic acid and iron. Whole grains may or may not be enriched.

5. Dairy

Dairy products are foods made from or containing mammalian milk. They are mainly produced by mammals such as cow, buffaloes, goats, sheep and camels. Dairy products include foods such as yoghurt, cheese and butter. Milk-producing facilities are referred to as Dairy. Dairy products are consumed throughout the world, with the exception of most East and Southeast Asia and parts of Central Africa.

Sources Of Food

There are different kinds of food sources, however, we can group them into 2 major categories. They are as follows:

  • Plants: We get our food from plants and various parts of the plants. There are few plants of which we only eat the seeds, we also eat leaves of some plants. According to Wikipedia, there are around 2000 species of plants which we use as food. People who only eat plants and vegetables as food are known as vegetarians.
  • Animals: Animals are another source of food. We get food from animals either directly or indirectly. Meat is the direct form of food whereas milk is an indirect form.

Food Nutrition

To maintain life organisms performs some basic functions, one of them is known as Nutrition. Nutrition is one of the basic function of life without which we can’t survive. In nutrition intake of food, digestion, absorption, assimilation and egestion of undigested foods are included.

Nutrient

Nutrients are the substance by which an organism get energy or it is used for biosynthesis of its body. For example, carbohydrates and fats are energy sources. While protein and minerals are nutrients for biosynthesis.

There are 5 types of nutrients. They are as follows:

1. Carbohydrate:

Thes are organic compounds in which the ratio of Carbon, Hydrogen and Oxygen is 1:2:1. Carbohydrate in the form of sugar and starch are major intake in animals and humans. 50 to 75% energy is obtained by oxidation of carbohydrate.

Function Of Carbohydrate

  • Carbohydrate works as fuel. During the process of respiration, glucose breaks into CO2 and H2O with the release of energy. One gram of glucose gives 4.2 kilocalories energy.
  • Nucleic acids are polymers of nucleosides and nucleotides and contain pentose sugar.
  • Lactose of milk is formed from glucose and galactose.
  • Glucose is used for the formation of fat and amino acid.

Types Of Carbohydrate:

  • Sugar
  • Starch
  • Fibre

Food Rich In Carbohydrates:

SoyBeans (Raw)30446
Lupin Beans (Raw)40971
Chickpeas61364
Kidney Beans (Raw)60333
Winged Beans(Raw)42409

2. Protein

The word protein was first used by J. Berzelius. This is a complex organic compound consisting of 20 types of amino acids. About 15% of the human body is protein. Besides C, H & O, nitrogen is also included in protein.

The human body needs 22 types of protein, 12 of which are synthesized by the body itself and the remaining 10 are produced by food. This is called an essential amino acid.

Function Of Protein:

  • It takes part in the formation of cells, protoplasm and tissues.
  • These are important for physical growth.
  • In case of necessity, protein provides energy to the body.
  • These control the development of genetic characters.
  • These are helpful in conduction also.

Types Of Protein:

  1. Simple Protein
  2. Conjugated Protein
  3. Derived Protein

3. Fat

Fat is an ester of glycerol and fatty acid. In which carbon, hydrogen and oxygen are present in different quantities. But proportionally less oxygen than carbohydrate.

Fatty acids are of two types:

  • Unsaturated Fat
  • Saturated Fat
  • Trans Fat

Functions Of Fat:

  • It provides energy to the body.
  • It remains under the skin and prevents the loss of heat from the body.
  • It makes the food material testy
  • It protects different parts of the body from injury.

Food Rich In Fat:

  • Greek Yogurt
  • Wild Salmon
  • Heavy Cream and Milk
  • Canola Oil
  • Tuna
  • Flax Seeds
  • Spirulina

4. Vitamins

Vitamin was invented by Sir F G Hopkins. The term vitamin was coined by Funk.

Vitamins are organic compounds required in minute quantities. No calorie is obtained from it, but it is very important in regulating chemical reactions in the metabolism of the body.

On the basis of solubility, vitamins are of two types:

  • Vitamin which is soluble in water: Vitamin-B and Vitamin-C.
  • Vitamin which is soluble in fat: Vitamin-A, Vitamin-D, Vitamin-E and Vitamin-K.

6. Minerals

Minerals are a homogenous inorganic material needed for the body. These control the metabolism of the body.
