Single-use plastic bottles contain harmful chemicals, stainless steel water bottles require breaking the bank in most cases; what about aluminum water bottles? Are aluminum water bottles safe to use? Are they a good choice for you?
This article will answer the questions and cover the potential health risks included in aluminum water bottles. It will also suggest you the safer alternatives to ensure you stay hydrated without worry.
Are Aluminum Water Bottles Safe to Use?
Aluminum water bottles are usually safe for our health. Even if there’s a chance of aluminum leaching into the water, it’s generally considered to be minimal and not harmful under normal use.
However, prolonged exposure to aluminum can be a problem. According to research, high exposure to Aluminum can disrupt calcium metabolism in our bodies. It can also induce oxidative stress, which leads to cellular damage in bone tissue.
Still, the chances of prolonged exposure to aluminum from water bottles are minimal and considered harmless.
Another noteworthy issue is the plastic lining inside aluminum water bottles that can contain BPA.
Why Are There Plastic Linings In Aluminum Water Bottles?
Below are the common reasons why aluminum water bottles come with a plastic lining:
- Aluminum can react with acidic beverages, which alters the taste of your drink. The plastic lining helps maintain the original taste of your water.
- Although aluminum is corrosion-resistant, it can still corrode when exposed to certain substances. The plastic lining prevents the corrosion effectively, especially from acidic drinks.
So, what’s wrong with the plastic lining? Why does it even matter?
The plastic linings can contain BPA. BPA or Bisphenol A is an industrial chemical commonly used in producing certain plastics and resins. This chemical is also an essential component in making epoxy resins or epoxy glue, which you may notice to be present in food packaging and bottles.
BPA poses significant health risks. BPA binds to estrogen receptors after it’s ingested in our bodies. It can disrupt fetal development, cell repair, energy levels, and reproduction.
BPA is also harmful to the brain and prostate gland of infants and children. Moreover, exposure to BPA can increase the risk of heart disease, ranging from 18-63%.
Does The Plastic Lining Leach BPA Into The Water?
Good question. Yes, BPA can leach into the water but only after the plastic lining is degraded. Here’s how the plastic lining breaks down and makes things unhealthy for you.
- Scratches and cracks from regular use can cause the lining to deteriorate.
- Leaving your bottle in a hot car can accelerate the breakdown of the plastic lining.
- Drinks like carbonated beverages and citrus juices can react with the plastic, which may cause to leaching of plastic compounds into your drink.
- Using a dishwasher for bottles that aren’t dishwasher-safe can degrade the lining more quickly due to high heat and harsh detergents.
How to Detect Damage Plastic Lining in Aluminum Water Bottles?
New bottles have an intact plastic lining, so there’s nothing to worry about leaching BPA into the water. However, over time, these linings can deteriorate, and cause further issues.
Check for any signs of discolouration, peeling, or bubbling in the plastic lining. Run your fingers inside the bottle to feel the surface. If it feels uneven or rough, the lining may be starting to break down. You will also feel a strong, metallic taste in the water if the plastic lining is compromised.
Replace your bottle if you notice any of these signs to avoid potential health risks.
What’s The Better Alternative to An Aluminum Water Bottle?
Stainless steel and glass water bottles are the safest options when it comes to the material of water bottles. However, they come with individual pros and cons as well.
For example, glass is more fragile than other materials and can break easily. But these bottles are chemical-free, made from natural materials, and can be safely cleaned in a dishwasher.
On the other hand, bottles that are made from food-grade stainless steel, do not have any plastic linings. They are easy to carry and very durable, though they are more expensive than aluminum bottles.
Last Thoughts
So, what’s the conclusion? Are aluminum water bottles safe to use?
Aluminum water bottles are generally safe only if you can avoid prolonged exposure to the material and the leaching of BPA into the water. Alternatives like glass and stainless steel bottles offer safer options without these concerns.
