How to eat and drink fewer microplastics
Microplastics are everywhere.They're in your liver,blood and even in your brain,and they're almost
impossible to avoid.36 Here are four ways to reduce your exposure in what you eat and drink.
37
Drinking bottled water could be introducing you to thousands of microscopic pieces of plastic.In
fact,bottled water is the biggest pathway to microplastic exposure.Researchers have found that an average
liter of bottled water contains about 240,000 plastic particles().Switching from bottled water to
filtered tap water has the potential to reduce microplastic intake.
Avoid plastic food containers.
Using plastic is often unavoidable,but there are many ways to reduce your food's interaction with
plastics,and that includes the plastic storage containers,said experts.38 That could be as simple
as buying butter in a glass container.
Use glass in heated conditions.
One study found that microwaving food in plastic containers and reusable food bags could release
more than 4 million microplastic particles per cm2in just three minutes.Heat causes microplastics to get
into your food,so avoid putting hot food into plastic packaging.39
Avoid highly processed foods.
40 One study found microplastics in all 16 protein products that researchers sampled.Of the
products tested,breaded shrimp had the highest concentrations of plastic particles.Highly processed
chicken nuggets contained 30 times as many microplastics per gram as chicken breasts
A.Choose to drink clean tap water.
B.Avoid plastic shopping bags.
C.Highly processed foods contain lots of microplastics.
D.Wash fruits and vegetables with warm water before eating.
E.Fortunately,some steps can be taken to reduce your exposure
F.And make sure that it's not stored in sunlight or other warm environments.
G.They also urge people to replace food in plastic containers with other choices.
