Is it safe to drink through a plastic straw in hot coffee?
Based on 1 peer-reviewed studykitchen
Verdict: Avoid
No. Hot coffee through a plastic straw pulls out plasticizers and microplastics with every sip.
What's actually in it
Plastic straws are polypropylene or polystyrene. Hot coffee (90°C) is near the softening point for some straws. The straw touches the drink for its entire contact area the whole time you drink.
What the research says
A 2025 study in J Agric Food Chem measured nanoplastic release from polypropylene in hot water, with release climbing steeply with temperature.
Use a stainless steel straw, glass straw, or platinum-grade silicone straw. Or just drink from the cup.
