Health: Food or cause of illness?

In the first place, hunger is a lack of calories. A healthy diet, however, does not only consist of enough energy but also a balanced mix of proteins, carbohydrates and fats as well as a large variety of essential micronutrients, such as iron, zinc, iodine, minerals and vitamins."Although the world food system provides an adequate supply of protein and energy for over 85% of people, only two-thirds have access to sufficient dietary micronutrients. The supply of many nutrients in the diets of the poor has decreased due to a reduction in diet diversity resulting from increased monoculture of staple food crops (rice, wheat, and maize) and the loss of a range of nutrient dense food crops from local food systems." (Synthesis, p. 54)Worldwide, two billion people are suffering from one or even several micronutrient deficiencies, with often fatal consequences. Short-term emergency measures, such as distributing vitamin A to pregnant women and infants, can save lives in acute cases and alleviate symptoms. Adding micronutrients to foods can also help. The key to a balanced and healthy diet, however, lies in the cultivation and consumption of a range of plants and other products with different vitamins and minerals, as well as in a way of processing food that preserves the quality its ingredients. This holds true for both the food self-sufficiency in rural areas and highly processed foods in urban supermarkets.

Malnutrition and obesity

In 2008, 1.4 billion people worldwide were overweight; approximately one third of them were obese. Over the past decades, this "global epidemic", as it is called by the WHO, has been spreading rapidly. A major driver of being overweight or obese is the consumption of energy-dense foods in combination with a lack of physical activity. In 1980, just one in four of all adults was overweight; in 2008, one third of the world population was affected, not only in industrialised nations but also in emerging economies and developing countries. Being overweight is considered a major cause of chronic conditions such as diabetes, high blood pressure, strokes and certain cancers."A focus on increased production and food security rather than diet quality has contributed to a rise in obesity worldwide and the double burden of under- and overnutrition in developing countries" (Global, p. 196)

Between them, undernutrition, obesity and malnutrition are responsible for most non-communicable diseases and health problems. They afflict almost half of the world’s population, albeit to different extents. What is more, they have a common root cause, namely the separation and disconnection of food production from consumption.
The IAASTD argues that it is essential to re-establish these links at all levels in order to bring food providers and consumers closer together. The fine cuisines of this world could show us the way. Many plant-based products, a few but high-quality animal products and as much variety as possible are the secret of Tuscan, Chinese, Indian and Oriental top chefs, who make use of the rich traditions of simple regional cuisines."Fiscal policies should take into account impacts on public health. Agricultural subsidies, sales taxes and food marketing incentives or regu­lations could be refocused to improve nutrition and public health as a primary aim, for example by promoting produc­tion and consumption of more healthy foods such as fruits and vegetables." (Synthesis, p. 56)
The IAASTD underlines that public policies, too, could help to ensure diet quality and diversity: they should be refocused to improve nutrition and public health. >>more

Facts & Figures

According to the latest WHO estimates, 1.4 billion people aged 20 or above were overweight in 2008. Of this number, more than 200 million men and nearly 300 million women were obese. In 2012, more than 40 million children under the age of five were overweight or obese.

Around 3.4 million adults die each year as a result of being overweight or obese. In addition, 44% of the diabetes burden, 23% of the ischaemic heart disease burden and between 7% and 41% of certain cancer burdens are attributable to being overweight and obese.

Our food systems have failed to address hunger and encourage diets that are a source of obesity. The UN Special Rapporteur on the Right to Food has made a series of recommendations that include: taxing unhealthy products; regulating foods high in saturated fats, salt and sugar; cracking down on junk food advertising; overhauling agricultural subsidies that make certain ingredients cheaper and supporting local food production, so that consumers have access to healthy, fresh and nutritious foods.

More than half of all adults in OECD countries, and one in five children, are overweight or obese. In India, China and Japan, under 4% were obese in 2012, whilst in the United States the figure reached 35.3%, followed by Mexico with 32.4%. In 2013, Mexico launched a comprehensive strategy to address the problem, including awareness-raising, health care, regulatory and fiscal measures.

According to the WHO, an estimated 250 million pre-school children are suffering from vitamin A deficiency. It is likely that in vitamin A deficient areas, a large proportion of pregnant women are affected.  An estimated 250,000 to 500,000 vitamin A-deficient children become blind every year, half of them dying within 12 months of losing their sight.

Two billion people worldwide suffer from one or more micronutrient deficiencies. 31% of all children under the age of five suffer from vitamin A deficiency. 68% of children under five in Sub-Saharan Africa and 66.5% in South Asia are iron-deficient. Iron-deficiency anaemia negatively affects the cognitive development of children, pregnancy outcomes, maternal mortality and the work capacity of adults.

Zoonoses are diseases transmitted between animals and humans. Around 60% of all human diseases and 75% of emerging infectious diseases are zoonotic. 56 zoonoses together are responsible for an estimated 2.7 million human deaths and 2.5 billion cases of human illness a year. For the top 13 zoonoses, the figures were 2.2 million human deaths and 2.4 billion cases of illness.

Agriculture is one of the most dangerous sectors to work in. Of the total estimated 335,000 fatal workplace accidents occurring worldwide each year, some 170,000 involve agricultural workers. Machinery, such as tractors and harvesters, is the biggest cause of injury. The use of pesticides results in around 70,000 poisoning-related deaths each year, as well as at least seven million cases of acute and long-term non fatal illness.

Agriculture remains by far the most important sector where child labourers can be found. Worldwide, 59% of all child labourers in the age group 5-17 years work in agriculture, including farming, fishing, aquaculture, forestry, and livestock. In 2012, this amounted to over 98 million girls and boys.

Antimicrobial resistance to antibiotics is a growing problem. In 2012, there were an estimated 450,000 new cases of multidrug-resistant tuberculosis (MDR-TB) detected worldwide. An estimated 170,000 deaths were caused by MDR-TB in 2012.

Approximately half of the world's population is at risk of malaria. In 2012, this led to about 207 million malaria cases and an estimated 627,000 deaths. Malaria mortality rates have fallen by 42% globally since 2000. Most malaria cases and deaths occur in sub-Saharan Africa.
