The low-cost food that is generally affordable to the poor in affluent nations is low in nutritional value and high in fats, sugars and additives. In rich countries, therefore, obesity is often a sign of poverty and malnutrition while in poorer countries obesity is more associated with wealth and good nutrition.
Some FODMAPs, such as fructose, are readily absorbed in the small intestine of humans via GLUT receptors. [19] Absorption thus depends on the appropriate expression and delivery of these receptors in the intestinal enterocyte to both the apical surface, contacting the lumen of the intestine (e.g., GLUT5), and to the basal membrane, contacting the blood (e.g., GLUT2). [19]
The Right to food is a human right for people to feed themselves in dignity, be free from hunger, food insecurity, and malnutrition. [200] As of 2018, the treaty has been signed by 166 countries, by signing states agreed to take steps to the maximum of their available resources to achieve the right to adequate food.
Prevalence, severity, and character of abdominal pain vary considerably among the various disease processes associated with intestinal malabsorption. For example, pain is common in patients with chronic pancreatitis or pancreatic cancer and Crohn's disease, but it is absent in many patients with coeliac disease or postgastrectomy malabsorption.

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.
Abetalipoproteinemia is a rare inherited disorder of fat metabolism that results in poor absorption of dietary fat and vitamin E. [9] The vitamin E deficiency associated with this disease causes problems such as poor transmission of nerve impulses and muscle weakness.
Food fortification is the process of adding micronutrients (essential trace elements and vitamins) to food as a public health policy which aims to reduce the number of people with dietary deficiencies within a population. Staple foods of a region can lack particular nutrients due to the soil of the region or from inherent inadequacy of a normal ...
Mineral deficiency is a lack of the dietary minerals, the micronutrients that are needed for an organism's proper health. [1] The cause may be a poor diet, impaired uptake of the minerals that are consumed, or a dysfunction in the organism's use of the mineral after it is absorbed.
