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).

Protect Your Body Against Toxic Chemicals With These Seven Food Items

Bonus: You probably already have some of these in your kitchen

Remember when your grandma talked about food being its own form of medicine? Well, we're here to tell you that she was right (yes, grandma is always right). Now, eating these foods isn't going to turn you into a superhero overnight, but it will certainly help your body protect itself from toxic chemicals found in the environment. For some of these items, we recommend buying organic if possible (you don't want to be ingesting more chemicals when you could be avoiding them!).

  • Berries: We're talking strawberries, blueberries, raspberries and even boysenberries. Berries are high in antioxidants which are particularly effective in reversing acrylamide toxicity (1). Acrylamide is a chemical produced during high-temperature cooking (think frying or baking), but can harm your reproductive system and mess up your liver, lymph and bone marrow DNA (1). Studies have shown that mice fed with diets containing berries saw a significant recovery in their sperm counts, activity rate, and an increase in the number of healthy sperm (1).
  • Cauliflower, Broccoli and all the cruciferous vegetables: If roasted brussels sprouts are your favorite veggie, you're in luck! Cruciferous veggies like broccoli sprouts, broccoli, cauliflower, kale, and brussels sprouts all contain a compound called sulforaphane. Sulforaphane is a phytochemical with antioxidant, anti-inflammatory and anticarcinogenic properties (2). These properties make sulforaphane-containing vegetables an ideal food to eat to prevent cadmium toxicity (2). Sulforaphane helps cells recover from and prevents cell death after exposure to cadmium (2). We really think sulforaphane is spectacular!
  • Olive oil: Olive oil isn't just delicious drizzled over pasta and salads, it's also great for decreasing the effect of polychlorinated biphenyls (PCBs) on the body (3). Even though PCBs were banned in the 1970s, they are slow to degrade and still persist in the environment (4). PCBs are carcinogenic and also harm the nervous and immune system (4). However, studies have shown that a diet containing olive oil decreases inflammation associated with PCB exposure (3).
  • Grapes: Grapes are high in resveratrol, a polyphenol that can reduce toxicity from exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) (3). As an antioxidant, resveratrol helps decrease oxidative stress (basically cell damage) caused by TCDD (3). Delicious when frozen or nibbled on with cheese, the resveratrol in grapes can also decrease PCB toxicity and protect against the development of type 2 diabetes, which is often associated with exposure to PCBs (3). This is also totally a reason to drink more wine, right?
  • Green tea: Green tea drinkers, rejoice! Epigallocatechin gallate (EGCG) is the active component of green tea and can decrease the cardiovascular inflammation and toxicity that comes from arsenic exposure (3). This drink also packs a one-two punch, as it's also protective against PCB toxicity by reducing oxidative stress and inflammation of cells (3).
  • Spinach: Strawberry and spinach salad anyone? Aside from being insanely delicious, spinach can actually increase the excretion of arsenic from the body. One compound found in spinach, folate, is necessary to complete the excretion process of arsenic from the body (5).
  • Orange Juice: If the word glyphosate sounds familiar to you, it's probably because it's one of the most common herbicides used in farming (7). Glyphosate is categorized by the World Health Organization as a likely carcinogen (6). Lucky for you, organic juice can actually be protective against glyphosate toxicity (7). Mice given orange juice after exposure to glyphosate were shown to have decreased liver, kidney and DNA damage compared to mice not given orange juice (7).

Don't forget to stock up on these fruits and vegetables the next time you're at the grocery store! They can be used in so many different recipes or simply eaten by themselves. Who knew protecting your health could be so tasty?!

5 ways to eat LESS meat without eating NO meat

Here's what to do if you can't give up the flavor of meat but still want to be healthier

Interested in eating less meat, but can't commit to being a full on vegetarian, because... bacon? We feel you! But regardless of how you feel, eating less meat is actually great for you and the environment! Wondering why? Meat is extremely energy intensive to produce, all the way from how much food is needed to feed animals, to the energy required to process and ship the meat to you (3). This makes livestock a major contributor to greenhouse gases, and therefore climate change (3). In fact, scientists have found that eating a more plant rich diet is the 4th most effective thing we can be doing to help stop climate change (4).

The next time your pantry is looking scarce, skip the retail store and head to your local farmers' market! Not only are these foods better for your health, but they often use less fossil fuels and you'll be contributing to the fight against climate change.

Supermarkets vs Farmers Markets

You may not realize it, but the food you see on the shelves in your neighborhood supermarket probably required a large amount of fossil fuel to get there. How else would a peach show up on the shelf in the middle of February?! Fossil fuels are needed to power machinery on farms, to transport food from other countries, to produce food packaging, and to create fertilizers and pesticides (1). And as we already know, fossil fuel consumption plays a huge role in climate change.

Instead of relying on internationally-sourced produce and lots of plastic, farmers' markets create a space where the focus is on locally produced food. Most markets only allow vendors to sell food that has been produced within 200 miles of the venue. Some markets are even more stringent and only allow the sale of food grown in the community or immediate surrounding farms. This has a huge impact in reducing the amount of fuel that is needed in the transportation of these foods. On average, locally sourced produce travels 27 times less distance compared to massed produced food (2). Less fossil fuels used means less stress on the climate!

Another problem with supermarkets is that they can rely on a ton of plastic to store its produce. Sometimes the plastic is needed to keep the produce fresh as it sits on shelves, sometimes it doesn't seem to serve a purpose at all (plastic-wrapped bananas, anyone?). Not only are these plastics unneeded, but they also have a toll on the environment. Over 99% of plastic is made from chemicals coming from fossil fuels (3). Plastics are responsible for clogging our drainage systems, leaching harmful chemicals that contaminate groundwater, and injuring and poisoning wildlife (4).

To reduce the amount of plastic waste, and thus fossil fuels, farmers opt out of using plastic packaging and market patrons are encouraged to bring reusable shopping bags to stow their purchases. Vendors at a farmers' market often stock produce on tables without any packaging whatsoever! Berries may come in a plastic container, but overall plastic use is pretty minimal.

Why Farmers' Markets?

Shopping at a farmers' market gives you a chance to connect directly with farmers and their support team. You can learn where the food was grown, and the important decisions behind certain growing practices like the cultivation of crops without the use of chemical fertilizers, pesticides, or other artificial agents AKA organic farming. A lot of vendors are certified organic by the USDA. If you're unsure, just ask!

An additional reason to shop at farmers' markets is because they often provide a wide-variety of foods that are not available in grocery stores. Ever wonder what a pluot or zebra melon taste like? Go to a farmers' market to find out! You can taste before you buy to discover and find new favorites. Also, vendors eat what they sell, so they can suggest ways to cook the fresh kohlrabi you've just bought but have never used before.

For those of you who live in areas with seasons, farmers' markets don't stop when the leaves fall and the snow comes. Some markets continue to operate and bring fresh food to communities year-round. Come winter, farmers begin to sell their fall storage crops such as potatoes, carrots, beets, onions, garlic, and squash. Some farmers with greenhouses will have spinach, arugula, chard and other hardy produce available.

Getting Started

Are you now convinced to pay your local farmers' market a visit? Not only is this experience more fun than your routine trip to the supermarket, but farmers' markets are also a great opportunity to introduce your family to healthy eating and environmentally responsible consumption. You are ultimately investing in your health and doing your part in combating climate change.

To start, you can go online and search for local farmers markets in your area to find out their hours of operation and location. Note that this information may change based on the season. When there, strike up a conversation with a farmer to learn more about the products they offer and the environmental practices they use in their business.

Sometimes after a long day at work, the last thing anyone feels like doing is cooking dinner. Eating out or ordering take out is just so easy, especially with modern technology! But before you open that food delivery app, you might want to keep reading. Some recent studies have shown a link between eating out and phthalate exposure.

What Are Phthalates Again?

Phthalates are endocrine-disrupting chemicals, which means they mess with your hormones. These sneaky chemicals can change the way hormones messaging and how the body reacts to them. Endocrine disrupting chemicals have been linked to serious health effects like cancer, developmental abnormalities and fertility issues. And you don't have to be exposed to a ton of phthalates to have negative impacts. In fact, studies show that low level exposure can impact your health (1).

How They Get into Food

Phthalates are used to make plastic flexible and durable. There are a ton of different steps in food processing and distribution that relies on plastic to get the job done. Food handling gloves, plastic packaging material, plastic parts in machinery, and flexible plastic tubing are all used when creating processed food. Phthalates can easily leach from plastic into food during any of these steps. The more processed a food product is, the higher the chance that its come into contact with phthalates.

Why does this matter? Well, two major studies recently looked at phthalate exposure associated with eating out and found concerning results. Both studies found a higher rate of exposure to two phthalates called DINP (Diisononyl phthalate), and DEHP (di-2-ethylhexyl phthalate) in people who had recently dined out. The first study found that people who dined out had phthalate levels that were approximately 35% higher than those who ate at home (2). Adolescents were especially susceptible to high phthalate levels because they were the most likely age group to eat out.

The second study had similar findings, as well as observing fatty fast food items like burgers or french fries could elevate phthalate levels even more (3). Both studies found that eating food that had been cooked at home significantly reduced phthalate exposure.

What to do Instead

The good news is that the body metabolizes phthalates very quickly and they'll leave your body within 24 hours. So the cheeseburger you had after that big night out over the weekend probably isn't still impacting your phthalate levels. And there's currently a petition going to stop fast food workers from using vinyl gloves, which could contain phthalates. If you find yourself ordering food more than you're cooking it, now might be a good time to swing by the grocery story. But if you just can't break that delivery habit, try ordering foods that are less fatty, and less processed like salads.

Weekly meal prep is a super easy way to regularly start cooking. Preparing weekly dinner on Sunday means you'll always have something ready when you come home from work! Shopping for groceries on Sunday is also an easy way to make sure there are ingredients already on hand when you make dinner during the week. We have some easy recipes on our site!

Are Copper Mugs Poisoning You?

What you need to know about the safety of copper cookware and drink ware

Copper, the pinkish-orange brassy metal that coats our pennies can also be found in the kitchen! We often see copper in those fancy mugs known for serving Moscow mules, but it is also found in other kitchenware like pots and pans. You may have seen some articles or blog posts warning about the dangers of kitchenware made of copper, or other voices claiming this fear is unnecessary and that these dishes and mugs are completely safe. Or, maybe you've never thought twice about it. Well…what's the deal?! Here we will clear up this mystery so you can feel comfortable and safe sipping on your refreshing Moscow Mule.

Copper Exposure and Health

Copper is a naturally occurring metal used industrially for electrical wiring, pipes, and other metal products and used agriculturally and in healthcare as an antimicrobial agent or contraceptive. Copper is an essential element, meaning that humans require some level of copper in our bodies(1). However, at high levels, (above 1,300 parts per billion), ingesting copper can irritate your digestive system and cause nausea, vomiting, stomach cramps, and diarrhea (2).

So, how are humans exposed to this metal? Like other metals, copper, when in contact with a liquid has the potential to leach off and become dissolved in the liquid. When consuming the liquid, any leached copper will be ingested and could cause the unfortunate digestive irritation mentioned above. The rate of this dissolution reaction depends on the properties of the metal, the properties of the liquid, and the temperature of these substances.

Copper in the kitchen is most commonly found in the form of mugs, or cookware like pots and pans. Copper kitchenware is sold either lined, meaning the inside is coated with a different, less corrosive metal, or unlined, where the item entirely copper. Going back to our fun chemistry lesson above, the potential to ingest copper at home (or at the bar!) comes from the possibility of the copper leaching into whatever substance you are cooking or drinking. So, the big question: Will the copper in your kitchen products leach and cause toxicity? In short, probably not.

Mugs – Although copper does leach faster than most metals used in cups, it would take many, many hours of sitting in the mug before your Moscow Mule became dangerous to drink (3). Of course, Moscow mules are not the only drink served in copper mugs, and other substances can behave a little differently. Most beverages are OK, but acidity and heat speed up the dissolution reaction (4). Something as acidic as lime juice would still take a few hours to leach, but to err on the side of caution, leaving hot and/or acidic substances in unlined copper dish ware should be avoided (3).

Pots and Pans – Because of the high temperatures used when cooking, unlined copper cookware should not be used (4)! The good news—nearly all copper cookware on the market is lined with a different metal. However, you can never be too careful! When cooking with copper items, make sure the inside is a different color, or that the label specifies "lined" to be certain that it is safe to use.

Pipes – The most common way humans are exposed to ingested copper is through tap water when copper faucets or storage pipes are used. If you are concerned about your water at home, run the water 15-30 seconds prior to drinking (2).

Our Advice

Don't fret about enjoying a drink out of a copper mug! If you are investing in new copper mugs, we recommend purchasing stainless steel-lined ones, but regardless there is no need to panic. If you have unlined mugs, just take care to ensure super hot or acidic substances don't sit in them for extended periods of time, and be extra cautious around children. As for pots and pans, invest in lined copper only. If you're on the market for some new copper kitchenware, here are some lined options pots, pans, and mugs. Now enough anxiety about copper, it's time to sit back, relax, and enjoy that Moscow mule!

Tasty, Vegetarian-Friendly Summer Grill Recipes

Trying to eat less meat but don't want to give up your grilling habit? We've got you

School's out for the summer and we're officially swapping out backpacks for shades, sunscreen and the good ole' grill. Yep, you heard us right, we're firing up the grill and believe it or not, no meat is involved. Trying your hand at incorporating more vegetables isn't just good for you, it's great for the environment too. In a nutshell, it takes a TON of energy and water to produce the steaks and pork ribs traditionally grilled (1). The extra carbon dioxide pumped into the air from raising livestock then contributes to increasing Earth's temperatures (2). So, if you're on board to beat the heat, keep on reading for some awesome recipes and ideas to try out this summer.

Endless Ideas for Healthy Homemade Popsicles (No Recipe Needed!)

A refreshing family friendly treat, without added food colorings, cane sugar, or plastic packaging.

Popsicles are such a fun treat for adults and kids whenever it gets hot outside! We put together a fun graphic where you can make your own recipe for a healthy homemade popsicle, using whatever you have on hand. We make all sorts of popsicles from leftover fruit, veggies, juices that we have laying around. It's a great way to use up that half of a banana or browning avocado that your kid didn't eat. And instead of becoming food waste (which is a huge contributor to climate change), it gets new life as an amazing treat. We like these silicone or stainless steel popsicle molds, cause they are super durable and we generally try to avoid plastics and food. Making your own popsicles is a great way to have fun, while being non-toxic. Many store bought popsicles contain load of cane sugar, food colorings, other additives, and plastic packaging. So pick one up a popsicle mold, choose a combination of tasty ingredients, blend, freeze, and enjoy!

In case you need some ideas to get started, here are some of our favorites:

Chocolate Fudge: Cocoa powder, avocado (or banana), coconut milk, and honey/maple syrup

Watermelon Strawberry Mint: Watermelon, Strawberries, Coconut water, and Mint

Spinach Blueberry Yogurt: Spinach, Blueberry, Banana, and Yogurt

Creamy Zucchini Pineapple: Zucchini, Pineapple, and Coconut milk

*A special tip on mixing colors. Mixing leafy greens with red or orange fruits/veggies (like carrot juice or strawberries) makes for a pretty brown popsicle. It will still taste good, but might not look as appetizing!
