Practical Applications

Genetically Modified Foods

What Are GM Foods?

Genetically modified (GM) foods are made from plants or animals whose DNA has been changed to give them new traits.

Why Modify Foods?

  • Pest Resistance: Crops that don’t need as many pesticides.
  • Better Nutrition: Adding vitamins and minerals.
  • Longer Shelf Life: Foods that stay fresh longer.

Are GM Foods Safe?

Most scientific studies show that GM foods currently on the market are safe to eat. However, people debate their impact on the environment and food supply.

Real-World Impact

GM foods help farmers grow more food and can make healthy food more available around the world.

Labeling and Choice

Some countries require labels on GM foods so people can choose what they eat.

Examples

  • Golden rice is engineered to have more vitamin A, helping reduce blindness in children.

  • Bt corn produces a natural insecticide, so farmers use fewer chemicals.
