We can’t live without food. Actually, we can survive only for a week with any nutrition to our body except water. But, food is important.
Do you know everything there is to know about food? How about finding out some trivia and facts about it?
- Food is any substance consumed to provide nutritional support for an organism
- Food is usually of plant or animal origin
- It contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals
- The substance is ingested by an organism
- It is assimilated by the organism’s cells to provide energy, maintain life, or stimulate growth
- Historically, humans secured food through two methods: hunting/ gathering and agriculture
- These two methods gave modern humans a mainly omnivorous diet
- Humanity has created numerous cuisines and culinary arts
- These include a wide array of ingredients, herbs, spices, techniques, and dishes
- Today, the majority of the food energy required by the ever-increasing population of the world is supplied by the food industry
- Food safety and food security are monitored by agencies like the International Association for Food Protection, World Resources Institute, World Food Programme, Food and Agriculture Organization, and International Food Information Council
- They address issues such as sustainability, biological diversity, climate change, nutritional economics, population growth, water supply, and access to food
- The right to food is a human right derived from the International Covenant on Economic, Social and Cultural Rights (ICESCR)
- This right recognizes the “right to an adequate standard of living, including adequate food”
- As well as the “fundamental right to be free from hunger”
- Most food has its origin in plants
- Some food is obtained directly from plants
- 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
- Corn, wheat, and rice account for 87% of all grain production worldwide
- Most of the grain that is produced worldwide is fed to livestock
- Some foods not from animal or plant sources include various edible fungi, especially mushrooms
- Fungi and ambient bacteria are used in the preparation of fermented and pickled foods like leavened bread, alcoholic drinks, cheese, pickles, kombucha, and yogurt
- Another example is blue-green algae such as Spirulina
- Inorganic substances such as salt, baking soda and cream of tartar are used to preserve or chemically alter an ingredient
- Many plants and plant parts are eaten as food and around 2,000 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 and humans
- 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 include cereals (corn, wheat, rice), legumes (beans, peas, lentils) and nuts
- Oilseeds are often pressed to produce rich oils
- Some of the most known ones are sunflower, flaxseed, rapeseed (including canola oil), sesame
- 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 lemon, pose a choking hazard
- While 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 within
- Many plants and animals have coevolved such that the fruits of the former are an attractive food source to the latter
- This is 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 are eaten as vegetables
- This includes tomatoes, pumpkins, and eggplants
- Vegetables are a second type of plant matter that is commonly eaten as food
- These include root vegetables (potatoes and carrots), bulbs (onion family), leaf vegetables (spinach and lettuce), stem vegetables (bamboo shoots and asparagus), and 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
- Food products produced by animals include milk produced by mammary glands, which in many cultures is drunk or processed into dairy products (cheese, butter)
- In addition, birds and other animals lay eggs, which are often eaten
- Bees produce honey, a reduced nectar from flowers, which is a popular sweetener in many cultures
- Some cultures consume blood
- Sometimes in the form of blood sausage, as a thickener for sauces, or in a cured, salted form for times of food scarcity
- 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
- One form of adulteration is an addition of another substance to a food item in order to increase the quantity of the food item in raw form or prepared form
- This technique may result in the loss of actual quality of food item
- These substances may be 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-dried, precooked 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 own
- 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 a crunchy chip
- Dehydration can reduce the weight of the food by sixty to ninety percent by removing water through evaporation
- Some foods dehydrate well
- Some examples are onions, peppers, and tomatoes
- Dehydration often produces a more compact, albeit slightly heavier, end result than freeze-drying
- Surplus precooked military Meals, Meals, Ready-to-Eat (MREs) are sometimes used by campers
- These meals contain precooked 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
- Diet food refers to any food or beverage whose recipe is altered to reduce fat, carbohydrates, abhor/adhore sugar in order to make it part of a weight loss program or diet
- 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 requires finding an acceptable low-food-energy substitute for some high-food-energy ingredient
- This can be as simple as replacing some or all of the food’s sugar with a sugar substitute as is common with diet soft drinks
- 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 component 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 to replace part of the flour and achieve a more significant energy reduction
- This ingredients may be resistant starch or dietary fiber
- Finger food is food meant to be eaten directly using the hands
- In some cultures, food is almost always eaten with the hands
- Ethiopian cuisine is eaten by rolling various dishes up in injera bread
- Foods considered street foods are frequently, though not exclusively, finger foods
- In the western world, finger foods are often either appetizers (hors d’œuvres) or entree/main course items
- Examples of these are miniature meat pies, sausage rolls, sausages on sticks, cheese and olives on sticks, chicken drumsticks or wings, spring rolls, miniature quiches, samosas, sandwiches, Merenda or other such based foods, such as pitas or items in buns, bhajjis, potato wedges, vol au vents, several other such small items and risotto balls
- Other well-known foods that are generally eaten with the hands include hamburgers, pizza, Chips, hot dogs, fruit and bread
- In East Asia, foods like pancakes or flatbreads and street foods such as chuan are often eaten with the hands
- Fresh food is food which has not been preserved and has not spoiled yet
- For vegetables and fruits, this means that they have been recently harvested and treated properly postharvest
- For meat, it has recently been slaughtered and butchered
- For fish, it has been recently caught or harvested and kept cold
