Food is any substance [1] consumed to provide nutritional support for an organism. Food is usually of plantanimal or fungal origin, and contains essential nutrientssuch as carbohydratesfatsproteinsvitaminsor minerals. The substance is ingested by an organism and assimilated by the organism's cells to provide energymaintain life, or stimulate growth.
Different species of animals have different feeding behaviours that satisfy the needs of their unique metabolismsoften evolved to fill a specific ecological niche within specific geographical contexts. Omnivorous humans are highly adaptable and have adapted to obtain food in many different ecosystems.
Landscape out meaning in telugu, humans secured food through two main methods: hunting and gathering and agriculture. As agricultural technologies increased, humans settled into agriculture lifestyles with diets shaped by the agriculture opportunities in their geography. Geographic and cultural differences has led to creation of numerous cuisines and culinary artsincluding a wide array of ingredientsherbsspicestechniquesand dishes.
As cultures have mixed through forces like international trade and globalizationingredients have become more widely available beyond their geographic and cultural origins, creating a cosmopolitan exchange of different food traditions and practices.
Today, the majority of the food energy required by the ever- increasing population of the world is supplied by the industrial food industrywhich produces food with intensive agriculture and distributes it through complex food processing and food distribution systems. The food system has significant landscape out meaning in telugu on a wide range of other social and political issues including: sustainabilitybiological diversityeconomicspopulation growthwater supplyand access to food.
The right to food is a human right derived from the International Covenant on Economic, Social and Cultural Rights ICESCRrecognizing the "right to an adequate standard of living, including adequate food", as well as the " fundamental right to be free from hunger landscape out meaning in telugu. Because of these fundamental rights, food security is often a priority international policy activity; for example Sustainable Development Goal 2 "Zero hunger" is meant to eliminate hunger by Most food has its origin in plants.
Some food is obtained directly from plants; but even animals that are used as food sources are raised by feeding them food derived from plants.
Cereal grain is a staple food that provides more food energy worldwide than any other type of crop. Some foods not from animal or plant sources include various edible fungiespecially mushrooms.
Fungi and ambient bacteria are used in the preparation of fermented and landscape out meaning in telugu foods like leavened breadalcoholic drinkscheesepickleskombuchaand yogurt. Another example is blue-green algae such as Spirulina. Many plants and plant parts are eaten as food and around 2, plant species are cultivated for food.
Many of these plant species have several distinct cultivars. Seeds of plants are a good source of food for animals, including humans, because they contain the nutrients necessary for the plant's initial growth, including many healthful fats, such as omega fats. In fact, the majority of food consumed by human beings are seed-based foods. Edible seeds landscape out meaning in telugu cereals cornwheatriceet ceteralegumes beanspeaslentilset ceteraand nuts.
Oilseeds are often pressed to produce rich oils - sunflowerflaxseedrapeseed including canola oilsesameet cetera. Seeds are typically high in unsaturated fats and, in moderation, are considered a health food. However, not all seeds are edible. Large seeds, such as those from a lemonpose a choking hazard, landscape out meaning in telugu seeds from cherries and apples contain cyanide which could be poisonous only if consumed in large volumes.
Fruits are the ripened ovaries of plants, including the seeds. Many plants and animals have coevolved such that the fruits of the former are an attractive food source landscape out meaning in telugu the latter, because animals that eat the fruits may excrete the seeds some distance away. Fruits, therefore, make up a significant part of the diets of most cultures. Some botanical fruits, such as tomatoespumpkinsand eggplantsare eaten as vegetables.
Vegetables are a second type of plant matter that is commonly eaten as food. These include root vegetables potatoes and carrotsbulbs onion familyleaf vegetables spinach and lettucestem vegetables bamboo shoots and asparagusand inflorescence vegetables globe artichokes and broccoli and other vegetables such as cabbage or cauliflower. Animals are used as food either directly or indirectly by the products they produce.
Meat is an example of a direct product taken from an animal, landscape out meaning in telugu comes from muscle systems or from organs offal. Food products produced by animals include milk produced by mammary glandswhich in many cultures is drunk or processed into dairy products cheese, butter.
In addition, birds and other animals lay eggswhich are often eaten, and bees produce honeya reduced nectar from flowers, which is a popular sweetener in many cultures. Some cultures consume bloodsometimes in the form of blood sausageas a thickener for sauces, or in a curedsalted form for times of food scarcity, and others use blood in stews such as jugged hare.
Some cultures and people do not consume meat or animal food products for cultural, dietary, health, ethical, or ideological reasons. Vegetarians choose to forgo food from animal sources to varying degrees.
Vegans do not consume any foods that are or contain ingredients from an animal source. Adulteration is a legal term meaning that a food product fails to meet the legal standards.

These substances may landscape out meaning in telugu either available food items or non-food items. Among meat and meat products some of the items used to adulterate are water or ice, carcasses, or carcasses of animals other than the animal meant to be consumed.
Camping food includes ingredients used to prepare food suitable for backcountry camping and backpacking. The foods differ substantially from the ingredients found in a typical home kitchen.
The primary differences relate to campers' and backpackers' special needs for foods that have appropriate cooking time, perishability, weight, and nutritional content. To address these needs, camping food is often made up of either freeze-driedprecooked or dehydrated ingredients.
Many campers use a combination of these foods. Freeze-drying requires the use of heavy machinery and is not something that most campers are able to do on their. Freeze-dried ingredients are often considered superior to dehydrated ingredients however because they rehydrate at camp faster and retain more flavor than their dehydrated counterparts.
Freeze-dried ingredients take so little time to rehydrate that they can often be eaten without cooking them first and have a texture similar to landscape out meaning in telugu crunchy chip. Dehydration can reduce the weight of the food by sixty to ninety percent by removing water through evaporation. Some foods dehydrate well, such as onions, peppers, and tomatoes. These meals contain pre-cooked foods in retort pouches.
A retort pouch is a plastic and metal foil laminate pouch that is used as an alternative to traditional industrial canning methods.
Such foods are usually intended to assist in weight loss or a change in body type, although bodybuilding supplements are designed to aid in gaining weight or muscle. The process of making a diet version of a food usually landscape out meaning in telugu finding an acceptable low-food-energy substitute landscape out meaning in telugu some high-food-energy ingredient. In some snacks, the food may be baked instead of fried thus reducing the food energy.
In other cases, low-fat ingredients may be used as replacements. In whole grain foods, the higher fiber content effectively displaces some of the starch components of the flour. Since certain fibers have no food energy, this results in a modest energy reduction. Another technique relies on the intentional addition of other reduced-food-energy ingredients, such as resistant starch or dietary fiberto replace part of the flour and achieve a more significant energy reduction.
Finger food is food meant to be eaten directly using the handsin contrast to food eaten with a knife and forkspoonchopsticksor other utensils. Examples of these are miniature meat pies, sausage rollssausages on sticks, cheese and olives on sticks, chicken drumsticks or wingsspring rollsminiature quichessamosassandwichesMerenda or other such based foods, such as pitas or items in bunsbhajjispotato wedgesvol au ventsseveral other such small items and risotto balls arancini.

Thus, fresh landscape out meaning in telugu is cheese which has not been dried or salted for aging. Fresh food has not been driedsmokedsaltedfrozencannedpickledor otherwise preserved. Freezing food preserves it from the time it is prepared to the time it is eaten.
Since early times, farmers, fishermen, and trappers have preserved grains and produce in unheated buildings during the winter season. In the food commodity industrythere are two processes: mechanical and cryogenic or flash freezing. The kinetics of the freezing is important to preserve food quality and texture.
Quicker freezing generates smaller ice crystals and maintains cellular structure. Preserving food in domestic kitchens during modern times is achieved using household freezers. Accepted advice to householders was to freeze food on the day of purchase.
The Food Standards Agency was reported as supporting the change, providing the food had been stored correctly up to that time. A functional food is a food given an additional function often one related to health-promotion or disease prevention by adding new ingredients or more of existing ingredients. Health food is food marketed to provide human health effects beyond a normal healthy diet required for human nutrition.

The World Health Organization WHO makes the following 5 recommendations with respect to both populations and individuals: [33].
Live food is living food for carnivorous or omnivorous animals kept in captivity ; in other words, small animals such as insects or mice fed to larger carnivorous or omnivorous species kept either in a zoo or as a pet. Live food is commonly used as feed for a variety of species of exotic pets and zoo animals, ranging from alligators to various snakesfrogs and lizardsbut also including other, non- reptilenon- amphibian carnivores and omnivores for instance, skunkswhich are omnivorous mammalscan technically be fed a limited amount of live food, though this is not a common practice.
Common live food ranges from crickets used as an inexpensive form of feed for carnivorous and omnivorous reptiles such as bearded dragons and commonly available in pet stores for this reasonwaxworms landscape out meaning in telugu, Landscape Meaning In Telugu 79 mealworms and to a lesser extent cockroaches and locuststo small birds and mammals such landscape out meaning in telugu mice or chickens.
