One of the key pillars of food security is:

Nutrition
Food safety
Food wastage reduction
All of the above

The correct answer is: All of the above.

Food security is the availability of food and the assurance that all people, at all times, have physical, social, and economic access to sufficient, safe, and nutritious food to meet their dietary needs and food preferences for an active and healthy life.

Nutrition is the process of taking in nutrients from food and using them for growth, maintenance, and repair of the body.

Food safety is the assurance that food will not cause harm to the consumer when it is prepared and/or eaten according to its intended use.

Food wastage reduction is the reduction of the amount of food that is lost or wasted throughout the food supply chain, from production to consumption.

All of these are key pillars of food security. Without nutrition, people cannot be healthy and productive. Without food safety, people can become ill from eating contaminated food. And without food wastage reduction, we are not making the most efficient use of our resources.

There are many things that can be done to improve food security. Some of these include:

  • Increasing agricultural productivity
  • Improving access to food
  • Reducing food waste
  • Promoting healthy diets
  • Investing in research and development

By working together, we can create a world where everyone has access to safe, nutritious food.
