Peanut Butter And Jelly Sandwich
A peanut butter and jelly sandwich (PB&J) consists of peanut butter and fruit preserves spread on bread. The sandwich is popular in the United States, especially among children; a 2002 survey showed the average American will eat 1,500 peanut butter and jelly sandwiches before graduating from high school. There are many variations of the PB&J, which itself is a hybrid between a peanut butter sandwich and a jam sandwich. In American terminology, '' jelly'' is a fruit-based spread, made primarily from fruit juice boiled with a gelling agent and allowed to set, while ''jam'' contains crushed fruit and fruit pulp, heated with water and sugar and cooled until it sets with the aid of natural or added pectin. Preparation In basic preparation methods, a layer of peanut butter is spread on one slice of bread and a layer of fruit preserves is spread on another before the two sides are sandwiched together. The water in preserves can make the bread soggy, especially when the sandwich ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bag Lunch
A packed lunch (also called pack lunch, sack lunch or brown-bag lunch in North America) is a lunch which is prepared before arriving at the place where it is to be eaten. Typically, it is prepared at home or at a hotel, or produced commercially for sale in vending machines (especially in Japan) or at convenience stores. They are often eaten in a school or workplace, or on an outing. Technique The food is usually wrapped in plastic, aluminum foil, or paper and can be carried ("packed") in a paper bag ("sack"), plastic bag or lunchbox. Lunchboxes made out of metal, plastic or vinyl are popular. They provide a way to take heavier lunches in a sturdier box or bag, and are also considered more environmentally friendly than disposable packaging. While packed lunches are usually taken from home by the people who are going to eat them, in Mumbai, India, tiffin boxes are most often picked up from the home and brought to workplaces later in the day by so-called dabbawallas.

Cardiovascular Health
Cardiovascular disease (CVD) is any disease involving the heart or blood vessels. CVDs constitute a class of diseases that includes: coronary artery diseases (e.g. angina, heart attack), heart failure, hypertensive heart disease, rheumatic heart disease, cardiomyopathy, arrhythmia, congenital heart disease, valvular heart disease, carditis, aortic aneurysms, peripheral artery disease, thromboembolic disease, and venous thrombosis. The underlying mechanisms vary depending on the disease. It is estimated that dietary risk factors are associated with 53% of CVD deaths. Coronary artery disease, stroke, and peripheral artery disease involve atherosclerosis. This may be caused by high blood pressure, smoking, diabetes mellitus, lack of exercise, obesity, high blood cholesterol, poor diet, excessive alcohol consumption, and poor sleep, among other things. High blood pressure is estimated to account for approximately 13% of CVD deaths, while tobacco accounts for 9%, diabetes 6%, ...

Polyunsaturated Fats
In biochemistry and nutrition, a polyunsaturated fat is a fat that contains a polyunsaturated fatty acid (abbreviated PUFA), which is a subclass of fatty acid characterized by a backbone with two or more carbon–carbon double bonds. Some polyunsaturated fatty acids are essential fatty acid, essentials. Polyunsaturated fatty acids are precursors to and are derived from polyunsaturated Fat, fats, which include drying oils. Nomenclature The position of the carbon-carbon double bonds in carboxylic acid chains in fats is designated by Greek alphabet, Greek letters. The carbon atom closest to the carboxyl group is the ''alpha'' carbon, the next carbon is the ''beta'' carbon and Locant#Greek_letter_locants, so on. In fatty acids the carbon atom of the methyl group at the end of the hydrocarbon chain is called the ''omega'' carbon because ''omega'' is the last letter of the Greek alphabet. Omega-3 fatty acids have a double bond three carbons away from the methyl carbon, whereas omega- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monounsaturated Fat
In biochemistry and nutrition, a monounsaturated fat is a fat that contains a monounsaturated fatty acid (MUFA), a subclass of fatty acid characterized by having a double bond in the fatty acid chain with all of the remaining carbon atoms being single-bonded. By contrast, polyunsaturated fatty acids (PUFAs) have more than one double bond. Molecular description Monounsaturated fats are triglycerides containing one unsaturated fatty acid. Almost invariably that fatty acid is oleic acid (18:1 n−9). Palmitoleic acid (16:1 n−7) and cis-vaccenic acid (18:1 n−7) occur in small amounts in fats. Health Studies have shown that substituting dietary monounsaturated fat for saturated fat is associated with increased daily physical activity and resting energy expenditure. More physical activity was associated with a higher-oleic acid diet than one of a palmitic acid diet. From the study, it is shown that more monounsaturated fats lead to less anger and ...

Recommended Daily Intake
The Dietary Reference Intake (DRI) is a system of nutrition recommendations from the National Academy of Medicine (NAM) of the National Academies (United States). It was introduced in 1997 in order to broaden the existing guidelines known as Recommended Dietary Allowances (RDAs, see below). The DRI values differ from those used in nutrition labeling on food and dietary supplement products in the U.S. and Canada, which uses Reference Daily Intakes (RDIs) and Daily Values (%DV) which were based on outdated RDAs from 1968 but were updated as of 2016. Parameters DRI provides several different types of reference values: * Estimated Average Requirements (EAR), are expected to satisfy the needs of 50% of the people in that age group based on a review of the scientific literature. * Recommended Dietary Allowances (RDA), the daily dietary intake level of a nutrient considered sufficient by the Food and Nutrition Board of the Institute of Medicine to meet the requirements of 97.5% of hea ...

Jelly (fruit Preserve)
Fruit preserves are preparations of fruits whose main preserving agent is sugar and sometimes acid, often stored in glass jars and used as a condiment or spread. There are many varieties of fruit preserves globally, distinguished by the method of preparation, type of fruit used, and its place in a meal. Sweet fruit preserves such as jams, jellies, and marmalades are often eaten at breakfast with bread or as an ingredient of a pastry or dessert, whereas more savory and acidic preserves made from " vegetable fruits" such as tomato, squash or zucchini, are eaten alongside savory foods such as cheese, cold meats, and curries. Techniques There are several techniques of making jam, with or without added water. One factor depends on the natural pectin content of the ingredients. When making jam with low-pectin fruits like strawberries, high-pectin fruit like orange can be added, or additional pectin in the form of pectin powder, citric acid or citrus peels. Often the fruit will be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Food Timeline
Lynne Olver (1958–2015) was a librarian and food historian, and the sole author of the ''Food Timeline'' website. Personal life Olver graduated from the University of Albany (SUNY). She was a librarian at the Morris County Library, New Jersey, and became its director in 2009. ''The Food Timeline'' In 1999, Olver created ''The Food Timeline'', a history website documenting culinary history, food history and recipes. Unlike many other food related websites, Olver gave citations to almost every statement on her site so that readers can verify her claims. Her research has been cited in peer-reviewed journals. In 2020, it was reported that the Olver family was searching for a person or persons to maintain and possibly grow the website. Virginia Tech On November 11, 2020, the Olver family announced on the ''Food Timeline'''s Twitter account that they selected the Virginia Tech The Virginia Polytechnic Institute and State University, commonly referred to as Virginia T ...

Social Class
A social class or social stratum is a grouping of people into a set of Dominance hierarchy, hierarchical social categories, the most common being the working class and the Bourgeoisie, capitalist class. Membership of a social class can for example be dependent on education, wealth, occupation, income, and belonging to a particular subculture or social network. Class is a subject of analysis for sociologists, political scientists, anthropologists and Social history, social historians. The term has a wide range of sometimes conflicting meanings, and there is no broad consensus on a definition of class. Some people argue that due to social mobility, class boundaries do not exist. In common parlance, the term social class is usually synonymous with Socioeconomic status, socioeconomic class, defined as "people having the same social, economic, cultural, political or educational status", e.g. the working class, "an emerging professional class" etc. However, academics distinguish socia ...

Smithsonian (magazine)
''Smithsonian'' is a magazine covering science, history, art, popular culture and innovation. The first issue was published in 1970. History The history of ''Smithsonian'' began when Edward K. Thompson, the retired editor of ''Life'' magazine, was asked by then-Secretary of the Smithsonian, S. Dillon Ripley, to produce a magazine "about things in which the Smithsonian nstitutionis interested, might be interested or ought to be interested." Thompson later recalled that his philosophy for the new magazine was that it "would stir curiosity in already receptive minds. It would deal with history as it is relevant to the present. It would present art, since true art is never dated, in the richest possible reproduction. It would peer into the future via coverage of social progress and of science and technology. Technical matters would be digested and made intelligible by skilled writers who would stimulate readers to reach upward while not turning them off with jargon. We would fin ...

Crabapple
''Malus'' ( or ) is a genus of about 32–57 species of small deciduous trees or shrubs in the family Rosaceae, including the domesticated orchard apple, crab apples (sometimes known in North America as crabapples) and wild apples. The genus is native to the temperate zone of the Northern Hemisphere. Description Apple trees are typically tall at maturity, with a dense, twiggy crown. The leaves are long, alternate, simple, with a serrated margin. The flowers are borne in corymbs, and have five petals, which may be white, pink, or red, and are perfect, with usually red stamens that produce copious pollen, and a half-inferior ovary; flowering occurs in the spring after 50–80 growing degree-days, varying greatly according to subspecies and cultivar. Many apples require cross-pollination between individuals by insects (typically bees, which freely visit the flowers for both nectar and pollen); these are called self-sterile, so self-pollination is impossible, making pollin ...
