Food is eaten to provide nutritional


Food is eaten to provide nutritional support to an animal [1]. Food is usually from plant or animal sources and contains essential nutrients such as sugars, fats, proteins, vitamins or minerals. The substance is eaten by an animal and is energized by the cells of the organism, sustaining life or promoting growth.

Or historically, people protected food through two methods: hunting and collecting and farming, which gave modern man a predominantly all-round food. Humanity around the world has created a myriad of culinary and culinary industries, including a wide range of ingredients, bs, spices, techniques and dishes.
Currently, the food industry provides the lion’s share of the food energy needed for the world’s growing population. Food safety and food security are monitored by organizations such as the International Food Security Organization, the World Resources Institute, the World Food Program, the Food and Agriculture Organization, and the International Food Information Council. They address issues such as sustainability, biodiversity, climate change, nutritional economy, population growth, water supply and access to food.

The right to food is a human right derived internationally from the Economic, Social and Cultural Rights (ICESCR), recognizing the “right to adequate food and adequate living” as well as the “fundamental right to freedom from hunger”.

Food sources

Most food plants originate. Some foods are obtained directly from plants; Even animals that are used as food sources are raised by feeding on food obtained from their plants. Cereal grains are a staple food that provides more food energy than any other type of crop in the world.  Most of the grain produced worldwide is fed to cattle.

Some foods derived from animal or plant sources include various edible fungi, especially mushrooms. Fermented and pickled foods such as fermented bread, alcoholic beverages, cheese, pickles, kambucha and yogurt are used to make fungi and enveloping bacteria. Another example is blue-green algae such as spirulina [[]] used to preserve or chemically modify any ingredient using inorganic substances such as salt, baking soda and tartar cream.

Food from plant sources
Many plants and plant parts are eaten as food and about 2 thousand plant species are cultivated for food. There are different distinct species of different species of this plant. []]
Plant seeds are a source of food for both humans and animals, as they contain essential nutrients for the initial growth of plants, including omega-3 fatty acids. Edible seeds include cereals (corn, wheat, rice, et citira), lemons (beans, peas, lentils, etc.) and nuts. Oilseeds are often pressed to produce rich oils – sunflower, flaxseed, rapeseed (including canola oil), sesame and anti.
Seeds are generally high in unsaturated fats and are considered moderately healthy foods. However, not all seeds are edible. Large seeds, such as those obtained from a lemon, pose a risk of asthma, while seeds from cherries and apples contain cyanide that can be toxic only if eaten in large quantities. [9]

The fruits are the ripe ovaries of the plant, including the seeds. Many plants and animals have come together in such a way that the fruits of the past are an interesting food source for the future, because the animals that eat the fruits may move the seeds a little farther. As a result, most cultures have a significant portion of diet. Some botanical fruits such as tomatoes, pumpkins and eggplants are eaten as vegetables [[10] (for more information, see fruit list))

Vegetables are a second type of plant substance that is usually eaten as food. 

AnimalsMain article: Animal source food and food discipline
Various raw meatsAnimals use the products they produce directly or indirectly as food. Meat is an example of a direct product taken from an animal, which comes from the muscular systems or organs (offal).
 Also, birds and other animals lay eggs that are often eaten, and bees produce honey, a reduced nectar from flowers, a popular sweet in many cultures. Some cultures take blood in the form of blood sausage, sometimes in the form of blood sausage, frequently as a deficiency, or in the form of cured, salted food in times of deficiency, and others use blood in a stew like waking straw 12 [12]
Some cultures and people do not consume meat or animal food products for cultural, dietary, health, moral or ideological reasons. Vegetarians prefer to abstain from food of varying degrees from animal sources. Vegans do not take any food that contains or contains ingredients from any animal source.

Adulterated foodMain article: Adulterated foodAdulteration is a legal term meaning a food product fails to meet legal standards. One form of adulteration to increase the amount of food in raw form or prepared form is the addition of another substance to a food item, which can result in loss of the actual quality of the food. These substances are either food items or non-food items. Some items used for adulteration in meat and meat products are carcasses of animals other than water or ice, carcasses, or animals used for animal consumption. [13]
Camping food
Dried-dried bacon bars can be used as camp food
An MRE package contentMain article: Camping foodCamping food includes ingredients used to make food suitable for backcountry camping and backpacking. The dishes differ considerably from the ingredients found in the typical home kitchen. The primary differences are related to the appropriate food requirements of campers and backpackers which include appropriate cooking time, degradation, weight and nutrients.
To address these needs, camp meals are often made with frozen-dried, pre-dried or dehydrated ingredients. Many campers use a combination of these foods.
Frost-drying requires the use of heavy equipment and most campers are able to do something on their own. Frozen-dried ingredients take so little time to re-hydrate that they are often eaten without first cooking and have a crunchy chip-like texture.
Dehydration can reduce the weight of food by sixty to ninety percent by removing water through evaporation. Some foods dehydrate as well as onions, peppers, and tomatoes. [14] [15] Dehydration often produces more compacts, although somewhat heavier than freezing-drying, the end result.
Surplus pre-military food, food, ready-to-eat (MRE) is sometimes used by campers. These dishes contain pre-cooked meals in a retort pouch. A retort pouch is a plastic and metal foil laminate pouch that is used as an alternative to the traditional canning method.
Diet food

These foods are usually made to help with weight loss or body type changes, although bodybuilding supplements are designed to help with weight gain or muscle gain.
The process of making a diet version of a food usually requires searching for an acceptable low-food-energy alternative to some high-food-energy ingredients. [116] It is easy to substitute sugar for some or all of the food sugar, Coca-Cola (e.g. Diet is common with diet soft drinks such as Coke). In some snacks, the food may be baked instead of fried resulting in reduced food energy. In other cases, low-fat ingredients can be used as substitutes.
In whole grain foods, the higher fiber content effectively replaces a few starch components in the flour. Since certain fibers have no food energy, this results in a moderate energy loss. Another strategy relies on the deliberate addition of other reduced-food-energy ingredients such as resistant starch or dietary fiber to replace the flour portion and achieve a more significant amount of energy loss.
Finger food

[[17] In some cultures, food is often eaten by hand; For example, Ethiopian food is cooked in a variety of dishes and eaten on injera bread. [17] Foods considered as street food are often not exclusive to finger foods.
In the Western world, finger foods are often an appetizer (Horse d’Ovres) or admission / main course item. Small meat pies, sausage rolls, sausages on sticks, sticks on cheese and olives, chicken drumsticks or wings, spring rolls, miniature quiches, samosas, sandwiches, meranda or other based foods such as pita or ban items are, vajji, alur , Several such small items and risotto balls (aransini). Other well-known foods that are usually eaten by hand include hamburgers, pizza, chips, hot dogs, fruit and bread.
In East Asia, pancakes or flatbreads (bing ) and street foods such as chuan (串, also pronounced chuan) are often eaten by hand.
Fresh food

Dairy products will be fresh and spoiled quickly. Thus, fresh cheese is cheese that has not been dried or salted for ages. The sour cream can be considered “fresh” (chrome french).
Fresh foods are not dried, smoked, salted, frozen, canned, pickled or otherwise preserved. [[19]
Frozen food

From the very beginning, farmers, fishermen, and traffickers have made arrangements to preserve the winter crops by preventing the growth of most of the bacterial species. In the food products industry, there are two processes: mechanical and cryogenic (or flash freezing). Frozen motions are important for food quality and texture preservation. Rapid accumulation produces small ice crystals and maintains cellular structure. The fastest freezing technology available using extremely low temperatures of cryogenic freezing liquid nitrogen -196 ° C (20320 F). [[21]
Preserving food in the pet kitchen in modern times is achieved by using household freezers. The advice received from homeowners was to freeze food on the day of purchase. The initiative of a supermarket group in 2012 (supported by the UK Waste and Resources Action Program) encourages food submission as soon as possible “with the date of food consumption”. The Food Standards Agency supported the change, saying food was stored properly until delivery time. [22]
Functional foodMain article: Effective food [23] The term can also be applied to purposeful reproductive features in existing edible plants. Such as purple or golden potatoes enriching anthocyanins or carotenoid content, respectively.The term was first used in Japan in the 1980s, where there is a government approval process for effective foods called Feeds for Specific Health Use (FSHU). [226]
Health foodMain article: Health foodHealth food is marketed to provide human health effects outside of the general healthy diet needed for food nutrition.  These products can be sold in health food stores or in the organic section of health food or grocery stores.
Healthy food
Thin greens, allium and cruciferous vegetables are key components of a healthy diet. 
For healthy people, a healthy diet is not complicated and consists mostly of fruits, vegetables and whole grains and includes no processed foods and sweetened beverages. The need for a healthy diet comes from a variety of plant-based and animal-based foods, although vegetarians need an animal source of vitamin B12 to follow a diet. [29] Medical and government agencies to educate people about what they should eat to stay healthy. By publishing various nutrition guides. In some countries, nutrition information labels are mandatory, allowing consumers to choose between foods based on health-related ingredients. [[30]
A healthy lifestyle is eating a healthy diet as well as practicing every day. A healthy lifestyle can reduce the risk of diseases such as obesity, heart disease, type 2 diabetes, high blood pressure and cancer. [[2]] [31]
There are healthy diets for people with various diseases or conditions, called medical nutrition therapy. There is also a preconceived notion of such specialized diets, such as dietary therapy in specialized Chinese medicine.

The World Health Organization (WHO) makes the following 5 recommendations for both the population and the individual: [32]
Maintain a healthy weight by using about the same amount of calories as your body.Limit fat intake. More than 30% of total calories should not come from fat. Prefer unsaturated fats in saturated fats…

400 grams of fruits and vegetables per day (potatoes, sweet potatoes, cassava and other starchy roots are not counted). A healthy diet also includes lemons (e.g., lentils, beans), whole grains and nuts.Limit general sugar intake to less than 10% calories (less than 5% calories or 25 grams may be better) [33]Limit salt / sodium from all sources and make sure the salt is iodized. Less than 5 grams of salt per day can reduce the risk of heart disease. [[34]Live food

From common live food cricket (commonly found in muscle and pregnant reptiles such as bearded dragons and pet stores for this reason), edible worms, food worms and small numbers of cockroaches and locusts, small birds and mammals such as rats or chickens.
Medical food
Novartis Fibersource HN Medical Food has been deployed to the Ivy PoleMain article: Medical foodTherapeutic diets are diets that are specifically formulated for the dietary management of a disease and have specific nutritional needs that cannot be met with a simple diet alone. In the United States, these were defined in the Food and Drug Administration’s 1988 Orphan Drugs Act Amendment [35] and are subject to the general food and safety labeling requirements of the Federal Food, Drugs, and Cosmetics Act. In Europe, the European Food Safety Authority in 2015 set the definition for “foods for special treatment” (FSMP). [3]]
Medical foods known in Europe as “food for special treatment” [337] differ from a wide range of foods for the use of special diets, from traditional traditional foods and dietary supplements that have health demands. The product must be minimal, to be considered as a treat food: [38] [39]
Eat food for oral ingestion or tube feeding (nasogastric tube)Be labeled for dietary management of specific medical disorders, diseases or conditions that require specific nutrition andIntended for use in medical supervision.Medical foods can be classified into the following categories:
Complete formula in terms of nutritionNutritional incomplete formulaFormulas for metabolic disordersOral rehydration products
Main article: Natural foods

Terms are used in food labeling and marketing with a variety of definitions of natural foods and “all-natural foods”, most of which are vague. The term is often used to refer to foods that are not processed and whose ingredients are all natural products (in the chemist’s sense of the word), thus appealing to nature. However, the lack of quality in most jurisdictions means that the term does not guarantee anything. In some countries, the term “natural” is defined and applied. It does not apply to others, such as the United States.
“Natural foods” are often thought of as foods that are not processed, or do not contain any food additives, or do not contain certain additives such as hormones, antibiotics, sweeteners, food coloring, or flavored foods. [40] %) While the survey favored products labeled “natural” over unmarked portions, it was based on common belief (86% of polled consumers) that the word “natural” did not indicate that the food contained any artificial ingredients [[41] Used and misused in various labels and advertisements [42]
The Codex Elementarius of the International Food and Agriculture Organization does not recognize the term “natural” but has a standard for organic food. [43]A negative-calorie diet is food that digests more food energy than the food it provides. Its thermal effect or specific dynamic action – the calorie “expenditure” of food digestion – will exceed its amount of food energy. 

Despite its repeated popularity in dieting guides, there is no scientific evidence to support the notion that any food is calorically negative. While some cold drinks are calorically negative, their effects are minimal [44] and drinking large amounts of water can be dangerous. Many prisons today support the requirement.

Main article: Seasonal food”Seasonal” here refers to the times of the year when the crop or flavor of a particular type of food is at its peak. Usually the item is cut with some exceptions; An example is sweet potatoes which are eaten quite a while after a harvest. It also appeals to people who prefer low-carbon foods that reduce greenhouse gas emissions from food intake (food miles).
