Nanotechnology has been keeping all of us up on our toes, in terms of how they were made and their components. This technology involves precise engineering and control of particles in the smallest scale. These Nanoparticles are measured in nanometers or billionths of one meter. So small that if a nano particle is a size of a football, a red blood cell would be the size of the whole football field, they are unbelievably small. Some nanoparticles have already been existing as part of the nature. A certain nanoparticles in carbon exist in a caramelized foods, but ultimately it’s the nanoparticles that are made in laboratories that post a threat to the environment and human health.
Recently the U.S. Food and Drug Administration (FDA) does not specifically require nanoparticles to undergone studies on its safety integrity. The government is not uptight about the issue of nano, however it does require manufacturers to conduct a tests related to the products that are associated with nano —the results were favorable to them, and these particles are found to be harmless. However, there are recent studies that would linked nano to some health issues.
A new study now suggests that nanomaterials in food and drinks could interfere with digestive cells and lead to the release of the potentially harmful substances to the environment. The report on dietary supplement drinks containing nanoparticles was published in the journal ACS Sustainable Chemistry & Engineering.
Robert Reed and colleagues note that food and drink manufacturers use nanoparticles in and on their products for many reasons. In packaging, they can provide strength, control how much air gets in and out, and keep unwanted microbes at bay. As additives to food and drinks, they can prevent caking, deliver nutrients and prevent bacterial growth. But as nanoparticles increase in use, so do concerns over their health and environmental effects.
To make life more complicated for consumers, many labels do not list whether or not the product contains nanomaterials and manufacturers almost never say whether their packaging contains these materials.
Harmful to the gut
Nanoparticle is truly an amazing discovery. How they were engineered is mind blowing. Its potential to be used in different ways is highly anticipated, thou they have not yet utilized in the fullest extent their effect on our health is still questionable.
