JUNK FOOD

Junk food is a pejorative term for food containing high levels of calories from sugar or fat with little protein, vitamins or minerals. Use of the term implies that a particular food has little "nutritional value" and contains excessive fat, sugar, salt, and calories. Junk food can also refer to high protein food like meat prepared with saturated fat -which some believe may be unhealthy; many hamburger outlets, fried chicken outlets and the like supply food is considered as junk food.

Despite being labeled as "junk," such foods usually do not pose any immediate health concerns and are generally safe when integrated into a well balanced diet. However, concerns about the negative health effects resulting from the consumption of a "junk food"-heavy diet have resulted in public health awareness campaigns, and restrictions on advertising and sale in several countries

Definition

Andrew F. Smith, in his book, Encyclopedia of Junk Food and Fast Food defines junk food as "those commercial products, including candy, bakery goods, ice cream, salty snacks, and soft drinks, which have little or no nutritional value but do have plenty of calories, salt, and fats. While not all fast foods are junk foods, most are. Fast foods are ready-to-eat foods served promptly after ordering. Some fast foods are high in calories and low in nutritional value, while other fast foods, such as salads, may be low in calories and high in nutritional value."

Foods commonly considered junk foods include salted snack foods, gum, candy, sweet desserts, fried fast food, and sugary carbonated beverages. Many foods such ashamburgers, pizza, and tacos can be considered either healthy or junk food depending on their ingredients and preparation methods. The more highly processed items usually fall under the junk food category, including breakfast cereals that are mostly sugar or high-fructose corn syrup and white flour or milled corn.

Especially in the case of ethnic foods, a classification as "junk food" could be perceived as rather offensive, given that such foods may have been prepared and consumed for centuries and may contain healthy ingredients. In the book, Panic Nation: Unpicking the Myths We're Told About Food and Health, a complementary point is argued: food is food, and if there is no nutritional value, then it isn't a food of any type, "junk" or otherwise. Co-editor Vincent Marks explains, "To label a food as 'junk' is just another way of saying, 'I disapprove of it.' There are bad diets - that is, bad mixtures and quantities of food - but there are no 'bad foods' except those that have become bad through contamination or deterioration."

Historically, people secured food through two methods: hunting and gathering and agriculture. Today, the majority of the food energyrequired 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 assustainability, 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), recognizing the "right to an adequate standard of living, including adequate food," as well as the "fundamental right to be free from hunger."

Cultural and religious diets

Dietary habits are the habitual decisions a person or culture makes when choosing what foods to eat. 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. In addition, the dietary choices of different countries or regions have different characteristics. This is highly related to a culture's cuisine.

Diet deficiencies

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. 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. It is estimated that at least 3 million children are blind due to vitamin A deficiency. Vitamin C deficiency results in scurvy. 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.

 

some factors to eat right

It's the 21st century and "junk food" has gone global. For better or for worse (mostly worse), junk food is now available all over the world. We see it most everywhere we go -- in grocery and convenience stores, fast-food restaurants, on television -- usually looking very appealing. But just what are the facts about junk food?

"Junk food" generally refers to foods that contribute lots of calories but little nutritional value. Of course, what's considered "junk food" depends on whom you ask. Some might say pizza is junk food, for example. But I personally don't think so, since it contributes real food with nutrients, like cheese and tomato sauce. Add whole-wheat or part whole-wheat crust, plus veggies as a topping, and I'd say pizza completely exits the junk food category.

One problem with junk foods is that they're low in satiation value -- that is, people don't tend to feel as full when they eat them -- which can lead to overeating. Another problem is that junk food tends to replace other, more nutritious foods. When people drink lots of soda, for example, they are usually not getting plenty of low-fat dairy or other healthful beverages like green tea or orange juice. When they're snacking on chips and cookies, they're usually not loading up on fruits and vegetables.

Most "junk food" falls into the categories of either "snack food" or "fast food." And then there are things like breakfast cereals. They seem innocent enough, but some of them could definitely be considered "junk food," as they mostly contain sugar or high-fructose corn syrup and white flour or milled corn.
