Greenhouse gas emissions are the main contributor of climate change, and are thus an important indicator of a food system's contribution to climate change. In addition, greenhouse gases from transforming land (clearing, burning, or otherwise removing existing vegetation) for agricultural use are a large source of food system greenhouse gas emissions. Climate change is associated with increased land surface temperature, extreme weather events, rising sea levels, and other changes to the environment. These changes may impact the quality, quantity, and safety of our food supply.

Urbanization can be a challenge to the food system, as with increased proportion of people living in urban areas, food production is at risk of declining, especially on low- and middle-sized farms. Urban areas demand high penetration of food distribution and retail.

Population growth is relevant as it speaks to how fast a population is changing, what the age profile of the population is, and gives clues to the age-dependency ratio. A fast growing population also means pressure on the food system to continue increasing supply to meet the demands of a larger population.

Packaged food sales may provide an idea of the availability and demand for processed foods in a country. Packaged foods often have a longer shelf-life, fewer issues with food safety, and added convenience for people. For example, canned vegetables may enhance yearlong access in areas where local production is low or highly seasonal. On the other hand, many packaged and processed foods are energy dense and high in added sugar, salt, and fats (see ultra-processed food sales).

This indicator proxies the availability of UPFs, defined as foods made of mostly industrial ingredients and additives with minimal amounts of unprocessed foods. These additives are not naturally occurring in the food but are added in the processing phase in order to increase palatability and shelf life. Examples of UPFs include sweet and savory snacks, instant noodles, confectionery, meat substitutes, and soft drinks, among others.

Supermarkets increase people's physical and economic access to a wide variety of foods, including both fresh and processed foods. Supermarket chains typically begin with market advantages in dry and packaged foods, though eventually expand to fresh foods. Supermarkets require high standards in food quality and safety and often put in place dedicated supply chains. They bring opportunities as well as competition for local farmers and traditional retailers.

Modern grocery store retailers increase people's physical and economic access to a wide variety of foods, including both fresh and processed foods. They also create opportunity and competition for local farmers and traditional food retailers.

Animal-source foods, particularly liver; bivalves including oysters, clams, and mussels; small oily fish; and meat, leafy greens, other vegetables, and pulses are good sources of dietary iron, which prevents iron-deficiency anemia. Other causes of anemia include intestinal parasitic infections, malaria, and other nutritional deficiencies. Women's iron intake needs are greater than men's. Iron deficiency during pregnancy can result in complications for mother and fetus, including low birth weight.
