What is food? Sources and types - WhatStudies

Food works for your body, grows and even repairs. The type of food you eat can affect the effectiveness of these processes. 

The function of the body and the food has completely complicated it. Eating is really one of the most complicated machine pieces that are desired. 

Choose from which foods in which numbers you can help you understand this complex relationship between your food and your body.

Food used to provide nutritious support is a substance for the body. It is normal of plants or animal origin and contains essential nutrients such as cod, fats, proteins, vitamins or minerals hydrates. 

Organisms have the intellectual substance and the substance contains the organs of cells to try to produce energy, foster life or stimulate growth.

Source of food:

Life is the food of life Without food, people can not live. So it's important for us to find out where our food comes from. Do you want to know that a cake is made of food that comes from plants? We try to find out more about food sources.

Most of the food comes from plants. Some foods come directly from the plants; but also animals that are used as food sources are taken by feeding food derived from plants. Cereal flake food provides more food energy worldwide than any other. 

Corn, wheat and rice - in each of its varieties - represent 87% of all cereal production worldwide. Most of the grain produced all over the world is livestock.

Some foods that do not come from animal or plant sources include various edible mushrooms, especially mushrooms. Mushrooms and environmental bacteria are used to prepare fermented and fermented foods such as leavened bread, alcoholic beverages, cheese, yogurt. Another example is blue algae  like Spirulina. 

Organic substances such as salt, bicarbonate and tartar cream are used to conserve or chemically divert the ingredients.

Well, there are two sources of food: plants and animals. All the food we eat comes from these two. The processed food we eat in our daily lives (like chips, pies, pizzas, sandwiches, etc.). A mixture of different ingredients obtained from plants or animals. We look at both.

Plant as a source of food:

Much of the food we eat from plants, trees, crops, turrets, leaves and sometimes even goes to the roots. The most obvious examples of the foods we get from plants are fruits and vegetables. Fruits and vegetables grow on plants.

Another example of food in plants compared to crops. These are rice, wheat, corn, mills, barley etc. Seeds are the best plants. After eating them, they are gathering. Most of the processed food is found as flour, bread, biscuits, etc. And we eat from the best plants.

Now the animals that eat food obtained from plants are now known as botanists. some example are cows, zebras, hippos, giraffes, buffalo's etc. These are some examples. So people who rely on plant foods are just vegetarians.

Many plants and plants are eaten as food for eating and about 2,000 plant species are being cultivated for food. Many of these plant types have seedlings.

Plant seedlings, including people, are a good source of food for animals, because they need food for the first start of growth, including many healthy fats such as omega fats. In fact, most of the human diet is a sailor. Vineyard (corn, wheat, rice, etc.) are legs, legumes (beans, dolls, ribbons, etc.), and nuts. Egg exams are often crushed to make rich oils - a plant of sand, flax seed, rape (including canola oil), sesame, etc.

Seeds are generally considered the healthiest diet for most and unsaturated fats. However, not all seeds are edible. Cyanide acids of lemon, resistant risks and acids with acne and apples can be toxic if consumed by large amounts of seeds.

Ovaries intend to kill plants, including seeds. Many of these plants and animals may have effective dietary outcomes from the previous diet, as the animals eating the seed fruit can be excluded.

Therefore, the results are an important part of classical cultural essays. Botanical fruits such as tomatoes, pumpkins and eggplants are vegetables. Vegetables are another type of plant that is commonly used as food.

These are basic vegetables (potatoes and carrots), onion (onion family), leafy vegetables (spinach and lettuce), root vegetables (bamboo shoots and asparagus) and flowering vegetables (like other vegetables such as peanuts and broccoli and cabbage or cauliflower).

Let us take at examples of some foods we get from plants and their different parts
  • Fruits: Apples, Mangoes ,Oranges, Bananas
  • Leaves: Spinach, Kale, Lettuce, Coriander
  • Root: Potato, Carrots, Turnips
  • Seeds: wheat, maize ,Rice, nuts (peanuts, almonds)

 Animals as a Source of Food:

Not all our food comes from plants. The best part of the food we eat is from animals, mostly from livestock. The animals of the bovine cultivate grown animals especially for food purposes. Some animals (such as those killed in their natural habitat), such as deer or rabbits or kangaroo.

Food is used directly or indirectly through animal production products. The meat is an example of direct product taken from the animal from muscle systems or organs.

Food produced by animals is a milk produced from mammal glands, which are drinking or refined dairy products (cheese, butter, etc.) in many cultures. In addition, birds and other animals often lay eggs that are fed, and the bees produce honey, and the lower nectar of flowers is a popular sweetener in many cultures.

Some cultures and people do not use meat or animal products for cultural, nutrition, health, moral or ideological reasons. Vegetarians choose to provide food at different levels from animal sources. Vegetarians do not eat foods that contain basic ingredients from original animals.

Some examples of such meat and their sources are
  • Beef from cows and buffalo's
  • Chevron which is goat meat
  • Chicken (poultry)
  • Mutton which is from lambs
  • Venison from deer

Another source of food is seafood. It is fish and other marine animals, such as crabs, lagoons, spices, etc. They eat people and are particularly important sources of coastal areas.

Then we will return to dairy products. It is milk, cheese, cream, cheese, butter, egg etc. These are the sources of food from animals. All of these are made from milk and / or eggs from animals such as cows, buffalo, goats. Honey is another food we get from animals and bees.

Other animals eat animals such as lions, tigers and leopards. Animals that eat animals and plants are food such as dogs and cats. People who eat meat or fish become commonplace for vegetarians.
Knowing what nutrients are, where foods can help you understand something about this complex diet and the relationship between your body.

Chemicals in food:

Food contains many different chemical ingredients - macronutrients (high nutrition ingredients such as protein), "micro-nutrients" (small nutrients such as vitamins), water. And raw food (food fiber). There may be other ingredients in foods.

Food is the colors (natural and synthetic), flavors, pharmaceutical active ingredients (caffeine, steroids and salicylates chemically affect the body), natural toxic substances (naturally occurring cyanides), additives and more about contaminants (things originate from contaminated environment such as pesticides ). Typical flavors, such as orange and passion fries, also depend on ten or more chemicals.

The chemical form of foods is replaced by storage, preservation and cooking. Food chemicals can interact with one another in the body. 

For example, the availability of iron from plant sources depends on vitamin C in the diet that consumes food. The method of absorbing carbohydrate from the intestines depends somewhat to the presence of food fibers, though the fiber does not absorb itself.

Physical form of food:

Food is more than just chemicals. Its physical properties are important. The size of food particles can affect how nutrition is made to absorb and absorb nutrients.

For example, eating a fuzzy apple is a nutritional value that differs from the consumption of all the same chemicals in the apple. Crushed rice is split apart from ground rice. Nutrients can easily be absorbed by peanut butter (paste) than cooked peanuts.

Alkaline or Acid:

Acidity and alkalinity of foods are physical properties, which are mainly considered. In fact, they are only important for changing gastric emptying, digestive gut and acidity or urinary alkalinity. Our body can handle extensive food acids. 

Learn more about this word and basics without a big problem. Acidic foods are usually acidic and alkaline foods usually have some soaps. The use of sodium bicarbonate (baking soda) can make food alkaline. It can cause loss of vitamin C and promote sodium intake.

Some Major types of food:

Studies show that people who consume more food from the sea (especially fish) have a long risk of survival and a number of diseases such as heart disease, dementia and depression.


Shellfish cannot be eaten often, which is offensive because it has more nutrients than every diet. It resembles the body meat in terms of nutrient density. The seafood eaten includes mussels, molasses and oysters.


Salmon is a kind of fish that is famous for its excellent taste and great nutrients, including protein and omega-3 fatty acids. It also contains vitamin D.
