The main active ingredient of wine is alcohol, and therefore, the health effects of alcohol apply to wine. A 2016 systematic review and meta-analysis found that moderate ethanol consumption brought no mortality benefit compared with lifetime abstention from ethanol consumption. A systematic analysis of data from the Global Burden of Disease study found that consumption of ethanol increases the risk of cancer and increases the risk of all-cause mortality, and that the level of ethanol consumption that minimizes disease is zero consumption.  Some studies have concluded that drinking small quantities of alcohol (less than one drink in women and two in men) is associated with a decreased risk of heart disease, stroke, diabetes mellitus, and early death. Drinking more than this amount actually increases the risk of heart disease, high blood pressure, atrial fibrillation, and stroke. Some of these studies lumped former ethanol drinkers and life-long abstainers into a single group of nondrinkers, hiding the health benefits of life-long abstention from ethanol. Risk is greater in younger people due to binge drinking which may result in violence or accidents. About 3.3 million deaths (5.9% of all deaths) are believed to be due to alcohol each year.
Some cultures and religions have restrictions concerning what foods are acceptable in their diet. For example, only Kosher foods are permitted by Judaism, and Halal foods by Islam. Although Buddhists are generally vegetarians, the practice varies and meat-eating may be permitted depending on the sects. In Hinduism, vegetarianism is the ideal. Jains are strictly vegetarian and consumption of roots is not permitted.
The preparation of animal-based food usually involves slaughter, evisceration, hanging, portioning, and rendering. In developed countries, this is usually done outside the home in slaughterhouses, which are used to process animals en masse for meat production. Many countries regulate their slaughterhouses by law. For example, the United States has established the Humane Slaughter Act of 1958, which requires that an animal be stunned before killing. This act, like those in many countries, exempts slaughter in accordance to religious law, such as kosher, shechita, and dhabīḥah halal. Strict interpretations of kashrut require the animal to be fully aware when its carotid artery is cut.
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.
Home cooking has traditionally been a process carried out informally in a home or around a communal fire, and can be enjoyed by all members of the family, although in many cultures women bear primary responsibility. Cooking is also often carried out outside of personal quarters, for example at restaurants, or schools. Bakeries were one of the earliest forms of cooking outside the home, and bakeries in the past often offered the cooking of pots of food provided by their customers as an additional service. In the present day, factory food preparation has become common, with many "ready-to-eat" foods being prepared and cooked in factories and home cooks using a mixture of scratch made, and factory made foods together to make a meal. The nutritional value of including more commercially prepared foods has been found to be inferior to home-made foods. Home-cooked meals tend to be healthier with fewer calories, and less saturated fat, cholesterol and sodium on a per calorie basis while providing more fiber, calcium, and iron. The ingredients are also directly sourced, so there is control over authenticity, taste, and nutritional value. The superior nutritional quality of home-cooking could therefore play a role in preventing chronic disease. Cohort studies following the elderly over 10 years show that adults who cook their own meals have significantly lower mortality, even when controlling for confounding variables.
Ultimate Indo-European origin of the word is the subject of continued debate. Some scholars have noted the similarities between the words for wine in Indo-European languages (e.g. Armenian gini, Latin vinum, Ancient Greek οἶνος, Russian вино [vʲɪˈno]), Kartvelian (e.g. Georgian ღვინო [ɣvinɔ]), and Semitic (*wayn; Hebrew יין [jaiin]), pointing to the possibility of a common origin of the word denoting "wine" in these language families. The Georgian word goes back to Proto-Kartvelian *ɣwino-, which is either a borrowing from Proto-Indo-European or the lexeme was specifically borrowed from Proto-Armenian *ɣʷeinyo-, whence Armenian gini. An alternate hypothesis by Fähnrich supposes *ɣwino- a native Kartvelian word derived from the verbal root *ɣun- ('to bend'). See *ɣwino- for more. All these theories place the origin of the word in the same geographical location, Trans-Caucasia, that has been established based on archeological and biomolecular studies as the origin of viticulture.
Cooking often involves water, frequently present in other liquids, which is both added in order to immerse the substances being cooked (typically water, stock or wine), and released from the foods themselves. A favorite method of adding flavor to dishes is to save the liquid for use in other recipes. Liquids are so important to cooking that the name of the cooking method used is often based on how the liquid is combined with the food, as in steaming, simmering, boiling, braising and blanching. Heating liquid in an open container results in rapidly increased evaporation, which concentrates the remaining flavor and ingredients – this is a critical component of both stewing and sauce making.
^ "Pesticides in Organic Farming". University of California, Berkeley. Retrieved 2014-06-17. Organic foods are not necessarily pesticide-free. Organic foods are produced using only certain pesticides with specific ingredients. Organic pesticides tend to have substances like soaps, lime sulfur and hydrogen peroxide as ingredients. Not all natural substances are allowed in organic agriculture; some chemicals like arsenic, strychnine, and tobacco dust (nicotine sulfate) are prohibited.
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).
