What Is Nutritional Value?

What Are Food-Purchasing Specifications?

Defining Your Dietary Profile
Nutrient profiles that define the basic criteria that food should comply with in order to be considered suitable for a health claim are being established, based on scientific advice from EFSA. In any known profit-driven economy, health considerations are hardly a priority; effective production of cheap foods with a long shelf-life is more the trend. For Nutrition in humans, see Human nutrition. Corporate control of our food system from seed to plate contributes to market abuses and is a threat to competition, food affordability and supply. It should be noted that supplements are just that -- they are intended to supplement healthy food.

What is a “Flavor Profile”?

Temperature is as much about the expectation as it is about the experience of hot or cold temperature. For a somewhat pedestrian example, consider potato salad. American cuisine demands that it be served cold, where German potato salad is served warm to hot.

Hot American potato salad is not only distasteful, but could be potentially harmful, owing to the billowy clouds of mayonnaise. The same holds true within cuisines as well. Consider again potatoes, this time in Vichyssoise and Potage Parmentier.

Essentially the same exact dish — potato leek soup — served at temperature extremes, provide completely opposite gustatory experiences. Sugar is by far our favorite flavor sensation. We eat entirely too much sweet food. Considering that refined sugar only entered the industrial age in the eighteenth century, it quickly became an integral part of cuisines throughout Europe.

Sweet is the primary taste component in desserts, but is also frequently paired with sour and salty for contrasting flavors in savory dishes. Bitter flavors provide counterpoints to sweet and savory foods. Bitter is more of a sensation than a flavor description. It is detectable in coffee, mustard, cocoa, olives and citrus peel.

We have a funny relationship with bitter. Coffee with cream and sugar, mustard with meat, cocoa with sugar and fat. By itself, not so much. Salt, soy sauce, red miso The degree to which sodium is detectable in food. This exam covers specific domains within the health sphere including; Clinical Intervention and Human Health.

The study found that health literacy increases with education and people living below the level of poverty have lower health literacy than those above it. Another study examining the health and nutrition literacy status of residents of the lower Mississippi Delta found that 52 percent of participants had a high likelihood of limited literacy skills.

For example, only 12 percent of study participants identified the My Pyramid graphic two years after it had been launched by the USDA. The study also found significant relationships between nutrition literacy and income level and nutrition literacy and educational attainment [93] further delineating priorities for the region.

Among these problems are the lack of information about food choices, a lack of understanding of nutritional information and its application to individual circumstances, limited or difficult access to healthful foods, and a range of cultural influences and socioeconomic constraints such as low levels of education and high levels of poverty that decrease opportunities for healthful eating and living. The links between low health literacy and poor health outcomes has been widely documented [94] and there is evidence that some interventions to improve health literacy have produced successful results in the primary care setting.

More must be done to further our understanding of nutrition literacy specific interventions in non-primary care settings [93] in order to achieve better health outcomes. Malnutrition refers to insufficient, excessive, or imbalanced consumption of nutrients by an organism. In developed countries, the diseases of malnutrition are most often associated with nutritional imbalances or excessive consumption.

In developing countries, malnutrition is more likely to be caused by poor access to a range of nutritious foods or inadequate knowledge. The aim was to boost nutrition and livelihoods by producing a product that women could make and sell, and which would be accepted by the local community because of its local heritage.

Although under- and over-nutrition are often viewed as human problems, pet animals can be under- or overfed by their owners, domesticated animals can be undernourished for macro- and micro-nutrients, affecting growth and health, and wild animals can be undernourished to the point of starvation and death. Nutritionism is the view that excessive reliance on food science and the study of nutrition can lead to poor nutrition and to ill health.

It was originally credited to Gyorgy Scrinis , [96] and was popularized by Michael Pollan. Since nutrients are invisible, policy makers rely on nutrition experts to advise on food choices. Because science has an incomplete understanding of how food affects the human body, Pollan argues, nutritionism can be blamed for many of the health problems relating to diet in the Western World today.

ULs are set a safe fraction below amounts shown to cause health problems. ULs are part of Dietary Reference Intakes. When too much of one or more nutrients is present in the diet to the exclusion of the proper amount of other nutrients, the diet is said to be unbalanced. High calorie food ingredients such as vegetable oils, sugar and alcohol are referred to as "empty calories" because they displace from the diet foods that also contain protein, vitamins, minerals and fiber.

Research indicates that improving the awareness of nutritious meal choices and establishing long-term habits of healthy eating have a positive effect on cognitive and spatial memory capacity, with potential to increase a student's ability to process and retain academic information. Some organizations have begun working with teachers, policymakers, and managed foodservice contractors to mandate improved nutritional content and increased nutritional resources in school cafeterias from primary to university level institutions.

Health and nutrition have been proven to have close links with overall educational success. There is limited research available that directly links a student's Grade Point Average G. Additional substantive data is needed to prove that overall intellectual health is closely linked to a person's diet, rather than just another correlation fallacy.

Nutritional supplement treatment may be appropriate for major depression , bipolar disorder , schizophrenia , and obsessive compulsive disorder , the four most common mental disorders in developed countries. Cancer is now common in developing countries. According to a study by the International Agency for Research on Cancer , "In the developing world, cancers of the liver, stomach and esophagus were more common, often linked to consumption of carcinogenic preserved foods, such as smoked or salted food, and parasitic infections that attack organs.

Several lines of evidence indicate lifestyle-induced hyperinsulinemia and reduced insulin function i. For example, hyperinsulinemia and insulin resistance are strongly linked to chronic inflammation, which in turn is strongly linked to a variety of adverse developments such as arterial microtrauma and clot formation i.

Hyperinsulinemia and insulin resistance the so-called metabolic syndrome are characterized by a combination of abdominal obesity , elevated blood sugar , elevated blood pressure , elevated blood triglycerides , and reduced HDL cholesterol.

The state of obesity clearly contributes to insulin resistance, which in turn can cause type 2 diabetes. Virtually all obese and most type 2 diabetic individuals have marked insulin resistance. Although the association between overweight and insulin resistance is clear, the exact likely multifarious causes of insulin resistance remain less clear.

It has been demonstrated that appropriate exercise, more regular food intake, and reducing glycemic load see below all can reverse insulin resistance in overweight individuals and thereby lower their blood sugar level , in those with type 2 diabetes.

In addition, reduced leptin signaling to the brain may reduce leptin's normal effect to maintain an appropriately high metabolic rate. In any case, analogous to the way modern man-made pollution may possess the potential to overwhelm the environment's ability to maintain homeostasis , the recent explosive introduction of high glycemic index and processed foods into the human diet may possess the potential to overwhelm the body's ability to maintain homeostasis and health as evidenced by the metabolic syndrome epidemic.

Antinutrients are natural or synthetic compounds that interfere with the absorption of nutrients. Nutrition studies focus on antinutrients commonly found in food sources and beverages. The relatively recent increased consumption of sugar has been linked to the rise of some afflictions such as diabetes, obesity, and more recently heart disease. Increased consumption of sugar has been tied to these three, among others.

In the same time span that obesity doubled, diabetes numbers quadrupled in America. Increased weight, especially in the form of belly fat, and high sugar intake are also high risk factors for heart disease. Elevated amounts of Low-density lipoprotein LDL cholesterol, is the primary factor in heart disease.

In order to avoid all the dangers of sugar, moderate consumption is paramount. Since the Industrial Revolution some two hundred years ago, the food processing industry has invented many technologies that both help keep foods fresh longer and alter the fresh state of food as they appear in nature.

Cooling is the primary technology used to maintain freshness, whereas many more technologies have been invented to allow foods to last longer without becoming spoiled. These latter technologies include pasteurisation , autoclavation , drying , salting , and separation of various components, all of which appearing to alter the original nutritional contents of food. Pasteurisation and autoclavation heating techniques have no doubt improved the safety of many common foods, preventing epidemics of bacterial infection.

But some of the new food processing technologies have downfalls as well. Modern separation techniques such as milling , centrifugation , and pressing have enabled concentration of particular components of food, yielding flour, oils, juices, and so on, and even separate fatty acids, amino acids, vitamins, and minerals. Inevitably, such large-scale concentration changes the nutritional content of food, saving certain nutrients while removing others. Heating techniques may also reduce food's content of many heat-labile nutrients such as certain vitamins and phytochemicals, and possibly other yet-to-be-discovered substances.

In addition, processed foods often contain potentially harmful substances such as oxidized fats and trans fatty acids. A dramatic example of the effect of food processing on a population's health is the history of epidemics of beri-beri in people subsisting on polished rice. Removing the outer layer of rice by polishing it removes with it the essential vitamin thiamine , causing beri-beri.

Another example is the development of scurvy among infants in the late 19th century in the United States. It turned out that the vast majority of sufferers were being fed milk that had been heat-treated as suggested by Pasteur to control bacterial disease.

Pasteurisation was effective against bacteria, but it destroyed the vitamin C. As mentioned, lifestyle- and obesity-related diseases are becoming increasingly prevalent all around the world. There is little doubt that the increasingly widespread application of some modern food processing technologies has contributed to this development. The food processing industry is a major part of modern economy, and as such it is influential in political decisions e. In any known profit-driven economy, health considerations are hardly a priority; effective production of cheap foods with a long shelf-life is more the trend.

In general, whole, fresh foods have a relatively short shelf-life and are less profitable to produce and sell than are more processed foods.

Thus, the consumer is left with the choice between more expensive, but nutritionally superior, whole, fresh foods, and cheap, usually nutritionally inferior, processed foods. Because processed foods are often cheaper, more convenient in both purchasing, storage, and preparation , and more available, the consumption of nutritionally inferior foods has been increasing throughout the world along with many nutrition-related health complications.

However, it has been almost 20 years since the label has been re-examined and analyzed to better serve consumers. The food label provides facts on calories and serving size, fat, sugar, sodium, carbohydrate, protein, vitamin, and mineral intake based on a 2, calorie diet. The ingredient list is loaded with valuable information however, is often overlooked. Ingredients are key to determining exactly what food is made of and ultimately, nutritional facts.

For example, many people don't realize a food marketed as a whole grain food that lists enriched wheat flour as the first ingredient, is primarily ordinary refined flour.

Therefore, the whole grain claim would not be entirely fact. This could only be determined by reading the ingredient list and comparing nutritional facts. Fat content is sometimes detailed for the consumer listing bad fats; saturated and trans and good fats; polyunsaturated and monounsaturated.

Saturated fats are mainly found in animal products such as meat, dairy, and eggs. Trans fats are found in fried and processed foods. Both can increase total cholesterol and LDL levels in the body.

Monounsaturated and polyunsaturated fats both lower total cholesterol; however, monounsaturated fats also increase HDL levels.
