Food production and genetically modified foods #SciChallenge2017

  1. 1. Food Production and Genetically Modified Foods By Alexandra Dăscălescu
  2. 2. The world population is increasing every second and because of that, some countries face the challenge of providing food for its inhabitants. Genetically modified (GM) food production has been adopted, as an option for increasing food production. Despite the fact that the production of GM food is quicker, some of them grow in hostile environments. GM food has a big impact on human health and some people question the safety of consuming GM foods.
  3. 3. Genetically modified food You don’t have to look hard to find GM food in the supermarket. More than 85 percent of the corn and soy grown in the US comes from seeds whose DNA has been altered and those 2 crops play an essential role in countless processed foods- from soda to salad dressing to bread.
  4. 4. What impact do GM foods have on our health? But no one really knows the answer to this question. GM food have been on the market since 1994, and research on their long-term effects on humans is scarce. To date most of the studies have been done on animals. Some of these studies link GM foods to: • Altered metabolism • Inflammation • Liver or kidney malfunction • Reduced fertility
  5. 5. In addition, allergy sufferers worry that, as genes are transferred between plants, allergenic proteins (from, say, peanuts or wheat) will pop up in unexpected places (like soy or sugar). Richard Goodman says that seed companies run many tests to prevent that kind of mistake from happening. But still, inserting new genes into a seed’s genome is always a gamble because scientists can’t predict all the consequences.

  7. 7. Top 10 GMO foods
  8. 8. Effects of GMOs DNA in GMO plants and animals contaminate forever and cannot be reversed once they’re introduced into the natural world. GMO production has caused a decline in the population of many beneficial plants, animals & insects, creating a dangerously unbalanced ecosystem.
  9. 9. 70% premature death in lab rats A recent study in France (one of the only comprehensive studies on GMOs and mammals) proved that lab rats exposed to GMO, had increased rates of cancer premature death, cancer and liver faliure. To date, there has been no long term study on the effects of GMOs on humans.
  10. 10. How to avoid GM foods •Buy food labeled 100% organic. •Buy 100% grass-fed meat. •Seek products that are specifically labeled as non GMO or GMO-free. •Shop locally. •Buy whole foods. •Grow your own food.
