Potential Impact Of GMOs On Humans & Human Health

Potential Impact Of GMOs On Humans & Human Health

There’s two sides of the debate when it comes to the potential impact of GMOs on humans and human health.

One side outlines the potential positive impact, while the other side outlines the potential negative impact.

Both sides are outlined below.


Potential Positive Impact Of GMOs On Humans & Human Health

  • There’s currently a scientific consensus that GMOs overall aren’t a significant risk for human health

To date, more than 3,000 scientific studies have assessed the safety of these crops in terms of human health and environmental impact. These studies together with several reviews performed on a case-by-case from regulatory agencies around the world have enabled a solid and clear scientific consensus: GM crops have no more risk than those that have been developed by conventional breeding techniques.

In addition, there is also extensive literature that compiles the socioeconomic and environmental benefits that transgenic crops have reported in two decades of commercialization

There is a scientific consensus that currently available food derived from GM crops poses no greater risk to human health than conventional food, but that each GM food needs to be tested on a case-by-case basis before introduction.

  • Can be engineered to have a better or increased nutritional profile compared to conventional food and crops

GMO foods and crops can be engineered to include more nutrition, such as calcium, protein or vitamins for example

  • Is adequately regulated and tested

Some scientists say that GMOs are adequately regulated and tested for what they are, so their positive impact on humans and human health is nothing to worry about

– geneticliteracyproject.org


  • Decreases overall inputs for farmers

Some argue that certain GMOs can be genetically engineered to require less water, energy, land, pesticide, fertizlier and so on. This means less inputs overall for farmers

  • Increases yield and efficiency for farmers

Several case studies report that GMO crops and foods increase yields and efficiency of farming for farmers

  • Decreases time and effort required for farmers

Higher yields means you can grow more with the same amount of land

Because less pesticide has to be sprayed, this also means less time and effort spent spraying 

Less time also has to be spent on tillage

  • Decreases cost, and increases revenue and profit for farmers

Increased efficiency and decreased time and inputs means increased revenues and profits for farmers

This is reported by several case studies

  • Can help solve other social and environmental issues like overpopulation, climate change, water scarcity, world hunger, food waste and more

Genetically engineered food that is engineered to last longer, grow in conditions of drought, grow in dry conditions, grow in less arable soil, that needs less water, and higher yields with more food – can help address many of the social and environmental issues described above

Potential Negative Impact Of GMOs On Humans & Human Health

  • Do present more risk to human health than conventionally grown food and crops

Some studies that aren’t in the consensus are critical of GMO crops

These studies say GMOs do present more of a risk than conventional crops and foods, in the short or long term 

– bettermeetsreality.com


  • Can be toxic, allergenic or less nutritious than natural food and crops

Either through genes introduced in the lab (which can be an issue when it comes to labelling), or through mixing of genes out in the field

  • Is not adequately regulated and tested

Some say that the regulations and testing for GMOs in some countries or states are not adequate

For example, the US has far fewer regulations and prohibitions on growing and importing GMOs than Russia

– bettermeetsreality.com


  • Can increase inputs for farmers

Some say GMO crops, through factors like producing herbicide resistant weeds, can require more inputs such as pesticide

– blogs.umass.edu


  • Doesn’t increase yield and efficiency for farmers

Some say the reports that GMOs increase yields compared to other farming methods are not accurate

– earthopensource.org


  • Doesn’t reduce time and effort required for farmers

Compared to some sustainable farming methods, some say GMOs don’t reduce time and effort

– earthopensource.org


  • Doesn’t decrease cost, or increase revenue and profit for farmers

Compared to some sustainable farming methods, some say GMOs don’t reduce costs or increase revenues and profits

– earthopensource.org


  • Doesn’t decrease health risks for farm workers (because more pesticide is actually required)

If the same or more pesticide is required for GMO crops and food, the health risks are the same or increased for farm workers who work around that pesticide

– earthopensource.org, and bettermeetsreality.com


  • Can provide legal issues and costs for farmers

Some people report farmers having legal issues if their GMO seeds blow across into a crop or field with natural crops

Farmers don’t want crossing of genes in their crops, and this can create issues at the consumer level too

– bettermeetsreality.com


  • Can be risky and damaging to the livelihood of developing country farmers

GMO seeds, some say, are provided with a restrictive contract to developing country farmers, and they aren’t renewable like natural seeds

This places debt and burden on these farmers to produce a worthwhile yield in one or two seasons, and can ruin some farmers financially if they have a bad season or two

– bettermeetsreality.com


  • Is simple a band-aid for other social and environmental issues like climate change, water scarcity, world hunger, food waste and more. Instead, we should focus on fixing the core problems with these other issues

Some argue that by using GMOs as a band aid to the above issues, that we are avoiding those issues.

Instead of avoiding, we should be solving the core issues
