Why they should be a treat instead of part of your daily routine

Canned Coffee is Convenient, But What About BPA?

Food

Now that we're all working from home, it's easy to get bored of our everyday homemade coffee routine. Sometimes we just want something different to wake us up in the morning or even a quick pick me up in the afternoon! That's where canned coffee comes into play. It's quick, convenient, and comes in a ton of flavors. But that convenience might come at a cost; there's been concerns surrounding the use of BPA in the lining of canned products. So, does canned coffee pose a risk to health? We looked at the research to find out.

The Problem With BPA in Cans

BPA, or bisphenol A, is a synthetic chemical that acts like estrogen in our bodies and it has been known to screw with important hormones like testosterone and thyroid hormones. Some of the common health problems associated with BPA include breast cancer, reduced sperm production, obesity, reproductive issues, disruption of brain development and function, and damaging effects to the liver (1). To make matters worse, there is more and more scientific evidence that even very low doses of BPA exposure can be harmful, especially for pregnant women and babies. Low doses of BPA exposure have been tied to abnormal liver function, chronic inflammation of the prostate, cysts on the thyroid and pituitary gland, and many more serious health effects during the early stages of life (5).

Even though BPA is definitely not a chemical we want to be exposed to, it's found basically everywhere, including our food. One common place to find BPA is the internal lining of canned foods or beverages. BPA can help prevent corrosion between the metal and the food or drink inside a can, but over time (or if stored under the wrong conditions like high temperatures), it can start to leach out and get into the food or drink (2). Even cans that say BPA free can have nasty BPA alternatives that have been shown to have similar hormone disrupting effects (7).

Studies have shown that canned soft drinks, beers, and energy drinks all had small traces of BPA in them. Beer was found with the highest concentration of BPA, followed by energy drinks. Soft drinks were found to have the lowest concentration of BPA. In order to find out where BPA in these drinks was coming from, researchers compared the canned drinks to the same drinks packaged in glass bottles. They found very little to no traces of BPA in the glass bottled drinks, which means that the source of BPA in the canned drinks was definitely coming from the cans themselves (2,3,4).

Even if there are only small traces of leachable BPA, it can still be harmful if we are consuming canned products on a regular basis.

Is Canned Coffee Safe?

With the recent increase in popularity of cold brew and other canned coffee drinks, there have not been extensive studies on BPA levels in canned coffee. However, one study of canned coffee drinks in Asia, where they have been popular for longer, did find that BPA was leaching into the coffee from the can. Interestingly, they also found that the more caffeine was in the coffee, the more BPA leached from the can into the drink. Meaning the more caffeine, the more BPA! (4,6) Now before you think you can get away with only drinking decaf canned coffee, keep in mind that caffeine only increases the leaching from the can, but it can still happen without it (6).

Even though the levels of BPA found in canned coffee were relatively small, because BPA is all around us in so many common products, we should try to limit our exposure as much as we can. This means that it's probably okay to drink a canned coffee every once in a while, but best practice is to not drink them every day. But if you're in the middle of a road trip and are desperate for some energy, don't get too stressed about grabbing a canned coffee!

Canned Coffee Alternatives

If you're starting to get worried about what coffee to buy when you're out and about or when you want something more than just plain coffee, don't stress! We thought of some easy and fun alternatives for your canned coffee fix that might make you forget all about it!

  1. Swap out the canned coffee for coffee in a glass bottle or tetrapaks whenever possible.
  2. Find some fun new ways to make coffee at home like using a Chemex or a nice French press!
  3. Go get a coffee at your local coffee shop. Support small businesses if you can!
  4. If you like canned coffee because of the flavors, try making your own caramel or mocha sauce at home. It's pretty easy and it saves money! For something icy and refreshing, we are partial to muddling some fresh mint with some cold brew.

The Pros and Cons of Silicone Cookware

A look into the safety of one of America's most popular cookware materials

Remember when we found out that the BPA in plastics were actually endocrine disruptors that could lead to all sorts of yucky health effects like early onset puberty, mess with our hormones and even cause cancer (1)? Since that news, we've seen an abundance of BPA-free cookware, drink ware and bakeware populating the marketplace. Some are even ditching traditional plastic products altogether. One of the most popular materials among industry and consumers alike is silicone. But have you ever wondered just how safe silicone is? We're breaking it down for you below- the good, the bad, and everything in between so you can make the safest choice!

Five Reasons to Love Silicone

  • Heat stable: Silicone can usually be used up to temperatures of 400(F) and can withstand going from extreme heat to extreme cold (2). This makes it a kid-friendly option, but is also great for busy adults who love to cook and leftovers freeze easily in silicone dishware. And when you're done, the silicone dishware can just be tossed into the dishwasher without any fear of it coming out melted after a high heat wash (2).
  • Flexible: Smash it, drop it, squeeze it, silicone will survive basically anything (except maybe an apocalypse) (2).
  • Degrades into large pieces: Believe it or not, this is actually a good thing! Because silicone products degrade into larger pieces, they are not as readily ingested by marine life, animal life and consequently, by humans as well (4)!
  • Durable: Compared to plastic that can crack, or glass that can shatter, silicone products are a great alternative that last basically forever (hurrah for our budgets!) (2).
  • Recyclable: Silicone can be down-cycled into other products (4). Once you're done with them, silicone products can be recycled into petroleum products that can be used again (4).

Five Reasons to be Wary of Silicone

  • Unknown long-term safety: Silicone products are fairly new to the market. Therefore, there have been very few studies conducted on the safety of silicone products and even fewer on the long-term health effects of using silicone products (6).
  • Chemical fillers: Depending on the quality of the silicone product, it may or may not contain chemical fillers (2,4). Generally, the higher the quality of silicone, the less likely it will contain chemical fillers (4).
  • Migration of chemicals into food: Studies have found chemicals in silicone products passing from storage containers, cookware and nursing teats (3,5).
  • Migration of chemicals into air: When silicone products are exposed to high temperatures (think baking), the chemicals in the product can be released into the air (2). The released particles tend to persist in the air and pose a health hazard to the lungs (2).
  • Special recycling process: In order for silicone to be down-cycled, you will need to bring products to special recycling centers (4).

What You Can Do to Keep Yourself Safe (Because Silicone Cookware Really is Awesome!)

  • Look for medical grade: Medical grade silicone should contain little or no chemical fillers (4). By purchasing medical grade silicone, you are ensuring you're getting a product that is as close to 100 percent silicone as possible.
  • Avoid chemical fillers: A quick tip to check for chemicals on a colored product is to pinch the silicone surface (4). If you can see white in the product while pinching, then a chemical filler has been used (4). A pure silicone product shouldn't change color at all (4).
  • Wash before using: Make sure to pre-clean all silicone products before using - this will decrease the amount and likelihood of chemicals getting into the food or air (2).
  • Adhere to maximum temperature: Always look to see what the maximum temperature a silicone product can withstand and don't exceed the temperature (2).

If you've made it here, you probably already know that bottled water isn't great. Plastic in general can also be tough because of the ever popular BPA and it's sister chemicals. So we found the best 7 glass water bottles that are well reviewed and that you can bring with you everywhere. That assures that even if your plastic water bottle is BPA free, you won't have to worry about BPA replacements.

Glass does tend to be a bit more heavy than stainless steel, but sometimes people complain about stainless steel having a taste or not being as easy to wash. We like how with these glass bottles, you can flavor your water or even drink iced tea in them, throw them in the dishwasher and then put water in them without a nagging smell or taste. Some of these brands have different sizes and colors, so poke around to find a size and look that work for you.

Also, in case you're wondering, it's tough to find glass bottles without plastic lids, but if the water isn't constantly touching the lid, a plastic lid usually isn't something to get too worried about. If you have some old plastic reusable water bottles kicking around (who doesn't!) then check out our advice about how to use them safely.

Everyone has their favorite water bottle - a Camelbak with the chewy straw, or a new shiny S'well bottle, or the Hydroflask that keeps your drink icy for days. And, we know that reusable plastic water bottles have some perks- lightweight, see through, indestructible- but they also have one big drawback, the plastic. Plastics, even ones that are BPA free, are often made of chemicals that can seep into water and affect your health. So, that's where this big question comes into play. Do I have to (or should I) ditch my beloved Nalgene with all my stickers from travels throughout the years?

Our answer is - you don't have to pitch it, but it probably shouldn't be your primary bottle either. You can stop reading here and check our our roundup of a dozen glass and stainless steel reusable water bottles if that's enough info for you, or you can keep reading and well give you some tips and nuggets of info on why those tips will make a difference.

You've finally returned home after seemingly endless train delays, and you're pretty much ready to eat everything in your fridge. Cue: intense music for your raid through the kitchen (I like Mission Impossible). There's nothing in the fridge except some pickles and ketchup, so you settle on a quick and easy microwavable meal that'll get piping hot food in your belly in less than 10 minutes. Trader Joe's Indian anyone? But, before you rip open that cardboard box and nuke the plastic tray, hear us out on why you might want to move that food to a glass container or plate instead.
