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.

Higher crop species richness and diversity are associated with several positive outcomes for production (yield stability, reduced pest and disease outbreaks, higher pollinator diversity) and for the environment (higher insect and bird richness and abundance, higher soil biodiversity). This indicator can be used to identify crops grown in areas with very low versus very high numbers of different crops within a 10x10 km area. Countries with lower average crop richness are likely to be growing in simplified farms and landscapes (monoculture systems) while countries with crop richness tending towards 42 are likely to be growing in multifunctional farms and landscapes. Note that the scale of the data (10x10 km) means that many small farms all producing different crops in monocultures will likely result in higher crop richness or diversity scores than several large farms using intercrop or crop rotation systems. There is no clear scientific consensus on a target crop richness to ensure sustainable production systems. A global target of 15 crops per 10x10km should be attainable for all cropland and could be used as a threshold across all commodities.

Yields measure the efficiency with which inputs are used to produce agricultural output. Improving production efficiency is considered a critical path to meet food and nutrition security needs of current and future generations. The yields data, subtracted from consumptive need can serve as an indicator of coherence between sustainable production and healthy consumption targets.

This indicates agricultural land dynamics, which can affect food supply and environmental quality.

Embedding at least 10% of natural and seminatural vegetation is being proposed as a planetary boundary to guarantee that agricultural lands have integrity and a minimum amount of natural capital to provide ecosystem services. Attaining 10% natural vegetation is a low target that all cropland systems must fulfill.

Countries with larger risk values suggests soil organisms are under high pressure signalling the need for changes in production systems to protect and restore soil biodiversity.

Adolescence is a formative time period of increasing independence where personal dietary habits and preferences are formed that may persist into adulthood. The WHO recommends daily consumption of 400 grams fruits and vegetables (https://www.who.int/news-room/fact-sheets/detail/healthy-diet).

Adolescence is a formative time period of increasing independence where personal dietary habits and preferences are formed that may persist into adulthood. Fast food typically has more calories and less nutrients than foods cooked at the home. Excessive consumption of fast food may increase the risk of overweight and obesity.

Adolescence is a formative time period of increasing independence where personal dietary habits and preferences are formed that may persist into adulthood. Consumption of sugar-sweetened beverages such as soft drinks has been associated with increased risk of overweight and obesity.

Adults who are obese are at increased risk of diet related noncommunicable diseases and premature mortality (The Global BMI Mortality Collaboration 2016).

Women who are underweight may not be receiving the adequate amount of energy and macronutrients, placing them at greater risk for micronutrient deficiencies, osteoporosis, infection, and mortality. Women of reproductive age who are underweight may be at greater risk for adverse pregnancy outcomes if they become pregnant.

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.

High consumption of sugary foods and beverages and processed flours and starches above the recommended amounts and proportions contributes to the development of Type II diabetes.
