What is food security?
As defined by the Food and Agriculture
Organization (FAO) of the United Nations:
Food security “exists when all people at all times have both physical and economic access to sufficient, safe, and nutritious food that meets their dietary needs for an active and healthy life.”

Challenges
Increasing global population Climate change Potable water shortage Loss of arable land, urbanization Increasing food wastage Food related issues
Malnutrition Obesity
Challenges An increasing global population, in combination with
climate change, poses a threat to food security as arable land becomes more scarce
Global population: 4.4 billion 6.1 billion from 1980-2000 Projected 9 billion 2050
Food production: 50% increase from 1980-2000 Degradation of arable land:
75% in Central America One-fifth in Africa 11% in Asia

Malnutrition Worldwide
WorldNumber and percentage of undernourished persons
2010-2012 868 million (12%)
2007-2009 867 million (13%)
2004-2006 898 million (14%)
1991-2001 919 million (15%)
1990-1992 1000 million (19%)
The FAO defines undernourishment as the state of consistently consuming less energy, in the form of protein and calories, to maintain a weight appropriate for height, and for mild activity.

Approximately 500 million people across the world are obese (BMI of 30 or greater), and if the population that is overweight was also included (BMI of 25 or greater), 1.5 billion people would fall into this category.
If nothing is done to remedy the issue, 1 billion people are predicted to be obese by 2030.

Vitamin/Mineral deficiencies
Vitamin A Approximately 250000 – 500000 children that are
Vitamin A deficient develop blindness each year Iron
Affects approximately 30% of people in the world Zinc
As of 2009, it was estimated that approximately 2 billion people were deficient in zinc

Functional ingredients are essential components in many foods e.g., vitamins, colours, flavours, preservatives, antimicrobials,
etc.) Usually need some sort of delivery system to optimize activity. Pay load substantially decreased

Protein Consumption
“FAO and other institutions[1] suggest that global meat production (Figure 1) and consumption will rise from 233 million tonnes (2000) to 300 million tonnes (2020), and milk from 568 to 700 million tonnes over the same period. Egg production will also increase by 30 percent. These predictions show a massive increase in animal protein demand, needed to satisfy the growth in the human population, and the increasing affluence of the emerging economies.”
