A subsistence diet is one that is just adequate for nutrition at a minimum cost. It is usually associated with good health. Subsistence foods are often low in salt and provide essential nutrients in a reasonable balance. They are also high in selenium and vitamin E, which are known to protect body cells by reducing peroxides and preventing diseases. Subsistence food production ensures self-sufficiency and a reduction in poverty and hunger.

What You'll Learn
Health Benefits
A subsistence diet is one that is self-sufficient and locally sourced. It is achieved through subsistence production, where community members use local practices to produce and preserve food. This type of diet is common in rural areas where food security is a prerequisite for health.
Subsistence diets are associated with a range of health benefits. Firstly, they provide essential nutrients that may otherwise be lacking in a person's diet. For example, selenium, a trace element found in seafood, kidney, liver, and some meats, is abundant in a subsistence diet. Selenium has numerous health benefits, including protecting body cells by reducing peroxides, preventing a form of heart disease called Keshan Disease, and counteracting the toxic effects of methyl mercury on nerves.
Secondly, subsistence diets are often lower in salt and sugar than diets consisting of store-bought foods. A lower salt intake can contribute to reducing high blood pressure, which is a common issue in the US. Additionally, subsistence diets are a good source of vitamin E, which is important for inhibiting the peroxidation of polyunsaturated fatty acids in the blood and blood vessel walls, thus reducing the risk of atherosclerosis.
Furthermore, subsistence diets are linked to better blood sugar management. A study found that eating more subsistence foods was associated with less glucose intolerance, which is a risk factor for Type II diabetes.
In addition, subsistence crops such as sorghum and millet porridge are recommended for pregnant women as they can ease childbirth due to their slimy texture. These foods also help maintain a normal menstrual cycle and control constipation.
Finally, subsistence diets can provide food security and reduce poverty and hunger, ensuring that people have access to sufficient, safe, and nutritious foods, which is essential for maintaining good health.

Food Security
Subsistence foods are often associated with good health and can provide a balanced diet. For example, traditional subsistence foods like seal, whale, walrus, and caribou tissues are rich sources of vitamin E, and diets that include these foods have been linked to better management of blood sugar and a lower risk of Type II diabetes. Additionally, subsistence foods are typically low in salt compared to processed store-bought foods, which may contribute to healthier blood pressure levels.
Subsistence farming and the collection of edible plant materials are common practices in rural areas to ensure food availability. This may involve growing vegetables, legumes, and grains in home gardens or fields and supplementing them with wild foods like wild greens and animal products obtained through hunting or raising livestock. For instance, some modern subsistence farmers grow vegetables and raise animals such as chickens, turkeys, and pigs for meat and eggs. They may also practice small-scale butchery to access a variety of nutrient-dense foods like hearts, livers, and bone broth.
Cultural heritage and indigenous knowledge systems are often sustained through subsistence food production practices. Rites of passage and the production of traditional food crops play a role in preserving cultural traditions. In some communities, unemployment is high, yet community members still engage in subsistence food production to ensure food availability and maintain their cultural practices. This approach to food security can lead to a healthier and more self-sufficient lifestyle while preserving traditional knowledge and cultural heritage.

Self-Sufficiency
Subsistence diets are often associated with good health. For example, the traditional diet of Siberian Yupik adults in Alaska, which includes a variety of subsistence foods, is linked to better health outcomes. This diet is rich in selenium, a trace element that offers several health benefits, including protecting against heart disease and counteracting the toxic effects of methyl mercury. Additionally, the vitamin E found in seal, whale, walrus, and caribou tissues contributes to the antioxidant effects that protect cell membranes from oxidative damage.
Subsistence food production ensures a constant supply of nutritious meals and can contribute to a balanced diet. For instance, subsistence crops such as porridge, whole-grain stew, and vegetables are unlikely to cause allergies and are often prescribed for family members as a preventive and curative measure. They can also address specific nutritional needs, such as feeding sorghum porridge to children between 6 and 9 months old to support their normal growth and reduce the risk of developmental diseases caused by malnutrition.
Subsistence farming can also have economic benefits, providing a reasonable income while reducing poverty and hunger. It promotes self-sufficiency and food security, ensuring consistent access to sufficient, safe, and nutritious food. This is particularly important in areas with high unemployment rates, as it enables unemployed household heads to produce their own food and maintain a healthy diet.
Overall, a subsistence diet focuses on self-sufficiency through local food production and preservation practices. It offers nutritional, health, and economic benefits, ensuring food security and promoting overall well-being.

Traditional Foods
A subsistence diet refers to a diet based on subsistence farming and food production, which is a self-sufficient method of farming that provides food security and good health. It is a common practice in rural areas, where community members use local practices to produce and preserve food.
In other parts of the world, such as Asia, subsistence farming involves cultivating small plots of land using simple tools and labour. This type of intensive subsistence agriculture is prevalent in densely populated areas, such as the Philippines, where farmers may create terraces on steep hillsides to cultivate rice paddies. The produce is used for local consumption and exchange against other goods.
In some communities, traditional foods in a subsistence diet may include crops such as wheat, oats, maize, and more heat-tolerant alternatives. These crops provide sources of grain, which can be pounded or grounded to make meals like porridge. Legumes, such as beans and peas, are also commonly grown and consumed, providing protein and a balanced diet.
Subsistence farming and traditional foods are often associated with cultural heritage and indigenous knowledge systems. They play an important role in ensuring food security, especially in rural and low-income areas, by providing self-sufficiency and reducing poverty and hunger.

Modern Subsistence Farming
Subsistence farming is a self-sufficient mode of agriculture in which a plot of land produces just enough food to feed the farmer's family or a small community working it. All produce grown is intended for consumption, not market sale or trade. It is a challenging way of life, and in most cases, it is the only option to prevent starvation and famine in many underdeveloped nations.
Subsistence farming is often the only option for survival in underdeveloped nations, but it is also argued to be economically efficient in some subtropical regions, such as Colombia and Papua New Guinea, where high rainfall levels allow for various crops to be produced year-round. However, this argument does not hold for many Sub-Saharan African regions, where poverty and famine levels are extremely high. The main challenges faced by subsistence farmers in these areas are the increasing trends in population growth, which are not met with a proportional increase in agricultural output.
Climate change also poses a significant threat to subsistence farming, as extreme temperatures and erratic weather patterns negatively impact crop yields. Farmers are forced to respond by increasing land and labour inputs, which can threaten long-term productivity and the future of household farms. For example, in some cases, farmers sell draft animals and consume seeds saved for planting, compromising their ability to farm in future seasons.
Despite the challenges, subsistence farming has persisted into the modern era and has even seen a resurgence during the pandemic. This resurgence may be attributed to the desire for self-sufficiency and food security during uncertain times. Additionally, subsistence farming can be cost-effective, especially with the use of modern inputs and advantages, such as simple and inexpensive farming methods for weed and soil management.
