Food quality traits for sustaining agriculture

The nexus of food, energy, and water

The Earth's population is expected to exceed 9 billion by 2050, posing significant challenges in meeting human needs while minimally affecting the environment. To support this population, we will need secure and safe sources of food, energy, and water. The nexus of food, energy, and water is one of the most complex, yet critical, issues that face society. There is no more land to exploit, and the supply of fresh water in some areas of the world limits the use of land for food. All solutions must also deal with the overlay of global climate change. Meeting current and future populations needs will require security in food, energy, and water supplies. A nexus approach is needed to improve food, energy, and water security integrating the management of the limited resources while transitioning to a more "green" economy, which provides adequate food, energy, and water for the expanding human population.

From detrimental to beneficial constituents in foods: tracking the publication trends in JAFC

A large part of the research focus on food constituents in the 20th century was toward health-detrimental contaminants-pathogens, toxins, chemical residues, and some food additives. This is reflected in the publications in the Journal of Agricultural and Food Chemistry and other journals. This era witnessed the formation of the U.S. Food and Drug Administration (FDA) and Environmental Protection Agency (EPA) and the rise and fall of DDT and other synthetic chemicals, as well as a number of artificial sweeteners, preservatives, and coloring/flavoring agents that attracted consumer and government attention. During the past 25 years or so, the emphasis in food chemistry and biochemistry has trended more toward health-beneficial chemicals in foods, as their examination yields information on naturally occurring components-polyphenolic antioxidants, unsaturated fatty acids, soluble fibers, and many other classes of constituents that may ward off chronic diseases. This perspective addresses the changes in emphases in published research to the present and trends that indicate the directions that food chemistry/biochemistry and related sciences might follow in the future.
