Doctors recommend glass or stainless steel cups, tumblers, coffee mugs, etc. to avoid harmful chemicals leaching into your drinks - making stainless steel the only non-breakable material recommended by doctors!
Deep scratches may reveal underlying layers or other metals that may potentially leak trace amounts of metal into the beverage, even though stainless steel is typically safe and does not leach dangerous compounds. The quantity, though, is often negligible and within acceptable levels, posing no serious health hazards.
Stainless steel is manufactured from safe, natural elements that are free of disease-causing chemicals and carcinogens. It's completely safe to drink water stored in stainless steel bottles even for long durations.
Yes, unequivocally, aluminum is safe for drinking, cooking, and eating, hence our confident choice of aluminum for our eco-friendly reusable bottles. Aluminum, stainless steel, and glass rank among the safest materials for beverage containers.
Metal conducts heat very well compared to ceramics, glass or plastics. This means that the hot drink inside a metal tumbler will quickly heat up the outside of the tumbler making it too hot to comfortably hold.
Insulation Capability of a Insulated Stainless Steel Tumbler
Such a tumbler is able to keep your piping hot coffee hot for up to 4 hours or icy cold coffee cold for 6 hours.
However, their superior quality compared to the other available options overlooked its cons. It is an undeniable fact that the conductivity of the metal leads to the mug heating quickly. In short, you can burn both your lips and fingers if holding the cup with a hot drink. But it also became stone-cold within minutes.
Many myths about the supposed health hazards of aluminum have now been debunked by researchers. It is very safe to drink from aluminum and continue refilling the bottle many times after, while plastic will slowly leach BPA and other chemicals into the drinking water if you continue to refill it.
The Bottom Line
The lead in water bottles like Stanley tumblers is sealed underneath a stainless steel layer through which it cannot escape into the contents of the bottle. However, there is a risk of lead exposure if the stainless steel caps at the bottom of these products become damaged.
Drinking from aluminium or low-quality stainless steel water bottles poses a health concern. If you wish to avoid ingesting any hazardous substances from drinking water, use a bottle made of #304 or 18/8 food-grade stainless steel.
Glass is the safest water bottle type and offers the purity of taste, but stainless steel offers insulation benefits that keep your beverages hot or cold. Don't forget about a filter!
Their findings: Iron, chromium and nickel were all found to leach into both alkaline and acidic foods and beverages, while none of the metals leached into distilled water. Leaching of iron, chromium and nickel was observed from both new and old utensils.
The chromium layer on the surface of stainless steel gives it a naturally anti-microbial resistance and creates a smooth surface with no micro-pores that harbour bacteria and mould. Ever noticed discolouration in a plastic water bottle or mould growing on the inside?
The viral tumblers were recently discovered to contain small amounts of lead in the base of the cup, surrounded by steel, to help insulate the contents from heat and cold. The good news — according to experts, the lead component is separate enough from the contents of the cup that people do not need to worry.
We prefer stainless steel or glass because many of the acrylic or plastic tumblers may have chemicals similar to BPA. We also link to some stainless steel straws because not all of these tumblers come with straws.
Glass is BPA free thanks to its inert qualities – it won't react to substances it comes into contact with. So, if you're looking for BPA free plastic alternatives, glass is the healthiest option.

All YETI drinkware is crafted from 18/8 kitchen grade stainless steel and are BPA free, meaning they are not only absolutely safe to drink from, but are also puncture and rust resistant.
Although it was initially believed to primarily affect the nervous system and bones, aluminum toxicity is now known to impact the cardiac, pulmonary, reproductive, gastrointestinal, and hematological systems. Symptoms include anemia, pulmonary fibrosis, and decreased bone density.
Oral exposure to aluminum is usually not harmful. Some studies show that people exposed to high levels of aluminum may develop Alzheimer's disease, but other studies have not found this to be true. We do not know for certain that aluminum causes Alzheimer's disease.
Aluminium containers score worse than plastic (but still better than glass) when we look at things like marine and freshwaste ecotoxicity due to the mining and processing and they are a smidge worse in human toxicity measures, but overall, a better choice.
From a purely scientific standpoint, stainless steel is a stable and inert compound; the material itself should not be able to alter the coffee's flavor. However, stainless steel is porous, which means past coffee drinks or anything else you've had in that cup, including the dish soap, may impart some flavors.
Material: Ceramic and porcelain are better heat conductors and add insulation while glass helps coffee cool quickly; good for people who are eager to sip. Stainless steel and silicone are durable materials for travel mugs, which might come with ceramic inserts to avoid off flavors.
