Nutrition Research Database Provides Nutrition Reports for Foods and Supplements
Szent-Györgyi concurrently elucidated much of the citric acid cycle. In general, whole, fresh foods have a relatively short shelf-life and are less profitable to produce and sell than are more processed foods. They are both a vegetable and a protein food. 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. Dietary intake data gathered by interview is entered directly into NDSR.

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.

As described, food insecurity is associated with low birthweight in infants.
Low birthweight is a risk factor for child stunting, which in turn is associated with overweight and obesity later in life. There is a need to implement and scale up interventions aimed at guaranteeing access to nutritious foods and breaking the intergenerational cycle of malnutrition.
Exclusive breastfeeding in the first six months and adequate complementary foods and feeding practices up to two years of age are key to ensuring normal child growth and development during this crucial window of opportunity.
Access to safe, nutritious and sufficient food must be framed as a human right, with priority given to the most vulnerable. Policies must pay special attention to the food security and nutrition of children under five, school-age children, adolescent girls and women in order to halt the intergenerational cycle of malnutrition.
A shift is needed towards nutrition-sensitive agriculture and food systems that provide safe and high quality food, promoting healthy diets for all. Last year SOFI pinpointed conflict and violence in several parts of the world as one of the main drivers of hunger and food insecurity, suggesting that efforts to fight hunger must go hand-in-hand with those to sustain peace.
They are also one of the leading causes of severe food crises. The number of extreme climate-related disasters, including extreme heat, droughts, floods and storms, has doubled since the early s. The number of extreme climate-related disasters, including extreme heat, droughts, floods and storms, has doubled since the early s, with an average of of these events occurring every year during the period of — Total number of natural disasters that occurred in low- and middle-income countries by region and during the period — Disasters are defined as medium and large scale disasters that exceed the thresholds set for registration on the EM-DAT international disaster database.
Climate variability and extremes are already negatively undermining production of major crops in tropical regions and, without adaptation, this is expected to worsen as temperatures increase and become more extreme. In many areas, climate extremes have increased in number and intensity, particularly where average temperatures are shifting upwards: Extreme heat is associated with increased mortality, lower labour capacity, lower crop yields and other consequences that undermine food security and nutrition.
In addition to increasing temperatures and changes in rainfall, the nature of rainy seasons is also changing, specifically the timing of seasonal climate events. Within-season changes may not register as extreme climate events droughts, floods or storms but rather are aspects of climate variability that affect the growth of crops and the availability of pasture for livestock, with potentially significant implications for food security and nutrition. Several countries — notably in Africa, Central America and Southeast Asia — experienced drought, not only through abnormally low total accumulated rainfall, but also through lower rainfall intensities and fewer days of rainfall.
Food security and nutrition indicators can clearly be associated with an extreme climate event, such as a severe drought, that critically challenges agriculture and food production. Of all natural hazards, floods, droughts and tropical storms affect food production the most. Drought, in particular, causes more than 80 percent of the total damage and losses in agriculture, especially for the livestock and crop production subsectors.
In relation to extreme events, the fisheries subsector is most affected by tsunamis and storms, while most of the economic impact on forestry is caused by floods and storms. If a drought is severe and widespread enough, it can potentially affect national food availability and access, as well as nutrition, thus magnifying the prevalence of undernourishment PoU nationally.
Severe droughts are worsening global hunger and reversing progress already made. Hunger is significantly worse in countries with agricultural systems that are highly sensitive to rainfall and temperature variability and severe drought, where the livelihood of a high proportion of the population depends on agriculture and where the country does not have in place sufficient support measures to counter the fallout.
In other words, for almost 36 percent of the countries that experienced a rise in undernourishment since , this coincided with the occurrence of severe agricultural drought. Out of 27 countries with increasing change points in the prevalence of undernourishment occurring under severe drought stress conditions, most 19 countries are in Africa, with the remaining four in Asia, three in Latin America and the Caribbean, and one in Eastern Europe.
The temperature anomalies associated with El Niño show that climate variability and extremes affect agriculture. If we look at increasing change points in the PoU time series we see that many correspond to occurrences of severe drought.
For example, for almost 36 percent of the countries that experienced a rise in undernourishment since , this coincided with the occurrence of severe drought. Most striking is the significant increase in the number of change points related to severe drought conditions in — in which nearly two-thirds of the change points occurred.
In these cases,the PoU increased from onwards, and this can be linked to severe droughts driven by El Niño in — A closer review reveals that many countries have witnessed periods of increased undernourishment over the past years; however, during the period of the ENSO event of — this change across so many countries contributed to a reversal of the PoU trend at the global level.
This association is further corroborated by a number of studies that show a strong link between drought and stunting in children. For example, drought events in Bangladesh are associated with a higher stunting rate around five and nine months after the beginning of the drought event. In rural Zimbabwe, one- to two-year olds exposed to drought face significantly lower growth velocity compared to children of the same age living in areas with average rainfall.
In sub-Saharan Africa, warmer and drier climates are related to declining food availability and increased prevalence estimates of childhood stunting.
Climate variability and extremes are among the key drivers behind the rise in hunger. Exposure of countries to climate variability and extremes is also a rising trend. In , the average of the PoU in countries with high exposure to climate shocks was 3. Even more striking is that countries with high exposure have more than doubled the number of undernourished people as those without high exposure. Prevalence unweighted and number of undernourished people in low- and middle-income countries with high and low exposure to climate extremes during the period of — Countries with high exposure are defined as being exposed to climate extremes heat, drought, floods and storms for more than 66 percent of the time, i.
See Annex 2 for the list of countries with high exposure to climate extremes and methodology. The impact of climate variability and extremes on agriculture and food security: Rome, FAO, for classification of countries with high and low exposure to climate extremes; FAO for data on prevalence of undernourishment. A high dependence on agriculture, as measured by the number of people employed in the sector, leaves the PoU 9.
For low-income countries, the increase is equal to The finding is different for middle-income countries where the rise in PoU is less pronounced and occurs later from — This tends to indicate that middle-income countries were able to absorb the impacts of increased exposure to climate extremes, but may not have been able to cope as well in the — period, possibly due to the severity of exposure to El Niño.
While hunger is on the rise, it is equally alarming that the number of people facing crisis-level food insecurity continues to increase. This represents an increase compared to and , when 80 and million people, respectively, faced crisis levels. In 34 of these 51 countries, more than 76 percent of the total populations facing crisis levels of acute food insecurity or worse — nearly 95 million people — were also affected by climate shocks and extremes. Where conflict and climate shocks occur together, the impact on acute food insecurity is more severe.
In , 14 out of the 34 food-crisis countries experienced the double impact of both conflict and climate shocks, which led to significant increases in the severity of acute food insecurity.
Floods cause more climate-related disasters globally than any other extreme climate event, with flood-related disasters seeing the highest increase — 65 percent — in occurrence over the last 25 years.

Feeding people well is as important as feeding people enough; shaping food systems to deliver safe, nutritious and sustainable food should be a priority. Interventions for better nutrition and health need to change behavior across the production-to-consumption continuum. But food quality is equally important.
