Many cultures hold some food preferences and some food taboos. Dietary choices can also define cultures and play a role in religion. For example, only kosher foods are permitted by Judaism, halal foods by Islam, and in Hinduism beef is restricted.[148] In addition, the dietary choices of different countries or regions have different characteristics. This is highly related to a culture's cuisine.
Wine is an alcoholic drink made from fermented grapes.[1] Yeast consumes the sugar in the grapes and converts it to ethanol, carbon dioxide, and heat. Different varieties of grapes and strains of yeasts produce different styles of wine. These variations result from the complex interactions between the biochemical development of the grape, the reactions involved in fermentation, the terroir, and the production process. Many countries enact legal appellations intended to define styles and qualities of wine. These typically restrict the geographical origin and permitted varieties of grapes, as well as other aspects of wine production. Wines not made from grapes include rice wine and fruit wines such as plum, cherry, pomegranate, currant and elderberry.

At the start of the 21st century, a two-tier structure has arisen, with a few international food processing giants controlling a wide range of well-known food brands. There also exists a wide array of small local or national food processing companies.[109] Advanced technologies have also come to change food manufacture. Computer-based control systems, sophisticated processing and packaging methods, and logistics and distribution advances can enhance product quality, improve food safety, and reduce costs.[108]


An emulsion of starch with fat or water can, when gently heated, provide thickening to the dish being cooked. In European cooking, a mixture of butter and flour called a roux is used to thicken liquids to make stews or sauces.[15] In Asian cooking, a similar effect is obtained from a mixture of rice or corn starch and water. These techniques rely on the properties of starches to create simpler mucilaginous saccharides during cooking, which causes the familiar thickening of sauces. This thickening will break down, however, under additional heat.

Being vegan doesn't have to mean missing out. These dishes, ranging from dinner-worthy entrées to mouth-watering desserts, show that a plant-based diet can be easy and delicious. For those who follow a vegan diet, which means no animal products of any kind including eggs, milk, cheese, yogurt, and other dairy products. We've focused on the widest interpretation of a vegan diet, so some of the recipes we've identified as vegan do include honey.
Dietary habits play a significant role in the health and mortality of all humans. Imbalances between the consumed fuels and expended energy results in either starvation or excessive reserves of adipose tissue, known as body fat.[149] Poor intake of various vitamins and minerals can lead to diseases that can have far-reaching effects on health. For instance, 30% of the world's population either has, or is at risk for developing, iodine deficiency.[150] It is estimated that at least 3 million children are blind due to vitamin A deficiency.[151] Vitamin C deficiency results in scurvy.[152] Calcium, Vitamin D, and phosphorus are inter-related; the consumption of each may affect the absorption of the others. Kwashiorkor and marasmus are childhood disorders caused by lack of dietary protein.[153]
Packaged foods are manufactured outside the home for purchase. This can be as simple as a butcher preparing meat, or as complex as a modern international food industry. Early food processing techniques were limited by available food preservation, packaging, and transportation. This mainly involved salting, curing, curdling, drying, pickling, fermenting, and smoking.[106] Food manufacturing arose during the industrial revolution in the 19th century.[107] This development took advantage of new mass markets and emerging technology, such as milling, preservation, packaging and labeling, and transportation. It brought the advantages of pre-prepared time-saving food to the bulk of ordinary people who did not employ domestic servants.[108]
Alcoholic drinks, including wine, are forbidden under most interpretations of Islamic law.[113] In many Muslim countries, possession or consumption of alcoholic drinks carry legal penalties. Iran had previously had a thriving wine industry that disappeared after the Islamic Revolution in 1979.[114] In Greater Persia, mey (Persian wine) was a central theme of poetry for more than a thousand years, long before the advent of Islam. Some Alevi sects–one of the two main branches of Islam in Turkey (the other being Sunni Islam)–use wine in their religious services.[citation needed]
Health food is food marketed to provide human health effects beyond a normal healthy diet required for human nutrition. Foods marketed as health foods may be part of one or more categories, such as natural foods, organic foods, whole foods, vegetarian foods or dietary supplements. These products may be sold in health food stores or in the health food or organic sections of grocery stores.
The red-wine production process involves extraction of color and flavor components from the grape skin. Red wine is made from dark-colored grape varieties. The actual color of the wine can range from violet, typical of young wines, through red for mature wines, to brown for older red wines. The juice from most purple grapes is actually greenish-white; the red color comes from anthocyan pigments (also called anthocyanins) present in the skin of the grape; exceptions are the relatively uncommon teinturier varieties, which actually have red flesh and produce red juice.
Food poisoning has been recognized as a disease since as early as Hippocrates.[135] The sale of rancid, contaminated, or adulterated food was commonplace until the introduction of hygiene, refrigeration, and vermin controls in the 19th century. Discovery of techniques for killing bacteria using heat, and other microbiological studies by scientists such as Louis Pasteur, contributed to the modern sanitation standards that are ubiquitous in developed nations today. This was further underpinned by the work of Justus von Liebig, which led to the development of modern food storage and food preservation methods.[136] In more recent years, a greater understanding of the causes of food-borne illnesses has led to the development of more systematic approaches such as the Hazard Analysis and Critical Control Points (HACCP), which can identify and eliminate many risks.[137]

The English word "wine" comes from the Proto-Germanic *winam, an early borrowing from the Latin vinum, "wine" or "(grape) vine", itself derived from the Proto-Indo-European stem *win-o- (cf. Armenian: գինի, gini; Ancient Greek: οἶνος oinos; Aeolic Greek: ϝοῖνος woinos; Hittite: wiyana; Lycian: oino).[40][41][42] The earliest attested terms referring to wine are the Mycenaean Greek 𐀕𐀶𐀺𐄀𐀚𐀺 me-tu-wo ne-wo (*μέθυϝος νέϝῳ),[43][44] meaning "in (the month)" or "(festival) of the new wine", and 𐀺𐀜𐀷𐀴𐀯 wo-no-wa-ti-si,[45] meaning "wine garden", written in Linear B inscriptions.[46][47][48][49] Linear B also includes, inter alia, an ideogram for wine, i.e. 𐂖.
Outstanding vintages from the best vineyards may sell for thousands of dollars per bottle, though the broader term "fine wine" covers those typically retailing in excess of US$30–50.[98] "Investment wines" are considered by some to be Veblen goods: those for which demand increases rather than decreases as their prices rise. Particular selections have higher value, such as "Verticals", in which a range of vintages of a specific grape and vineyard, are offered. The most notable was a Château d'Yquem 135 year vertical containing every vintage from 1860 to 2003 sold for $1.5 million. The most common wines purchased for investment include those from Bordeaux and Burgundy; cult wines from Europe and elsewhere; and vintage port. Characteristics of highly collectible wines include:

Long-standing advice to consumers to freeze food on the day of purchase is to be changed by a leading supermarket chain, as part of a national initiative to further reduce food waste. [...] instead advise customers to freeze food as soon as possible up to the product's 'use by' date. The initiative is backed by the government's waste advisory body, the Waste and Resources Action Programme (Wrap) [...] Bob Martin, food safety expert at the Food Standards Agency, said: "Freezing after the day of purchase shouldn't pose a food safety risk as long as food has been stored in accordance with any instructions provided. [...]"
Anticarcinogens that may help prevent cancer can also be found in many food especially fruit and vegetables. Antioxidants are important groups of compounds that may help remove potentially harmful chemicals. It is however often difficult to identify the specific components in diet that serve to increase or decrease cancer risk since many food, such as beef steak and broccoli, contain low concentrations of both carcinogens and anticarcinogens.[144] There are many international certifications in cooking field, such as Monde Selection、A.A. Certification、iTQi. They use the high quality evaluation methods to make the food become more safe.

The Mayo Clinic Diet provides practical and realistic ideas for including more physical activity and exercise throughout your day — as well as finding a plan that works for you. The diet recommends getting at least 30 minutes of exercise every day and even more exercise for further health benefits and weight loss. The diet also emphasizes moving more throughout the day, such as taking the stairs instead of an elevator.
Wine is important in cuisine not just for its value as a drink, but as a flavor agent, primarily in stocks and braising, since its acidity lends balance to rich savory or sweet dishes.[106] Wine sauce is an example of a culinary sauce that uses wine as a primary ingredient.[107] Natural wines may exhibit a broad range of alcohol content, from below 9% to above 16% ABV, with most wines being in the 12.5–14.5% range.[108] Fortified wines (usually with brandy) may contain 20% alcohol or more.
Rising food prices in those years have been linked with social unrest around the world, including rioting in Bangladesh and Mexico,[122] and the Arab Spring.[123] Food prices worldwide increased in 2008.[124][125] One cause of rising food prices is wealthier Asian consumers are westernizing their diets, and farmers and nations of the third world are struggling to keep up the pace. The past five years have seen rapid growth in the contribution of Asian nations to the global fluid and powdered milk manufacturing industry, which in 2008 accounted for more than 30% of production, while China alone accounts for more than 10% of both production and consumption in the global fruit and vegetable processing and preserving industry.[126]
For people who are healthy, a healthy diet is not complicated and contains mostly fruits, vegetables, and whole grains, and includes little to no processed food and sweetened beverages. The requirements for a healthy diet can be met from a variety of plant-based and animal-based foods, although a non-animal source of vitamin B12 is needed for those following a vegan diet.[29] Various nutrition guides are published by medical and governmental institutions to educate individuals on what they should be eating to be healthy. Nutrition facts labels are also mandatory in some countries to allow consumers to choose between foods based on the components relevant to health.[30]
