Food Preservatives

A food preservative is a substance added to foods to make them last longer, thus the name preservative. They are added to foods that go bad quickly and can be found in all kinds of products in our grocery stores. Preservatives work to preserve food in a few different ways. Some prevent the growth of bacteria and mold; others prevent delicate fats from going rancid.

There are so many preservatives out there. While preservatives added to foods should be “approved,” this doesn’t mean they’re guaranteed to be safe for everyone always. And it doesn’t mean that the food they are preserving is healthy.

Foods with preservatives are more processed so less nutritious and are not exactly health foods, despite what may be written on the label. There is really no standard for “All Natural,” for example. It’s more of a term manufacturers use to cash in on the trend towards healthier eating.

Even if you don’t mind preservatives, you probably should cut down on these kinds of foods, anyway.

So, let’s learn more about a few common food preservatives.

Salt

That’s right – salt is a preservative.

FUN FACT: The term “salary” is from the Latin word for salt. It’s thought that it came from the ancient Romans who would pay employees, allowing them to buy salt. Either that, or it was for their work conquering and/or guarding salt mines/roads. Either way, salt was sought because of its ability to preserve food before the advent of refrigeration.

In today’s day and age, with fridges and freezers in every home and grocery store, and refrigerated trucks, salt is not essential for food preservation. But our taste buds still seem to crave it on an epic scale. The average American eats over 3,400 mg of sodium per day, well over the recommended 2,300 mg/day. Much of that is because it’s found in processed foods.

According to Harvard Health: “… reducing dietary salt (table salt that is only sodium, chloride and iodine) will lower blood pressure, reduce the risk of heart attack and stroke, and save lives.”

Salt is one of those all-too-common food preservatives that many of us do better with less of, especially when it comes from processed foods. Since I rarely eat processed food, I use mineral salt like Pink Himalayan or Celtic Grey for example, a bit more liberally to take advantage of the important minerals they provide.

Nitrites (Nitrates and Nitrosamines)

Nitrites are preservatives added to processed meats. They’re not bad in and of themselves, but they do turn into harmful chemicals called nitrosamines. Nitrosamines are carcinogens found in cigarette smoke. Nitrites form nitrosamines when they’re cooked at high heat, and sometimes even when exposed to the high acid environment of the stomach.

Nitrites are added to meats to keep the pink-red color and prevent “browning,” mostly in bacon, ham, sausages and lunch meats. Since nitrites can change into nitrosamines, nitrites are one-step away from being the “bad guys.”

Another interesting thing is that processed meats have been linked with colon cancer. Because of the nitrites? Perhaps, but either way, nitrosamines are a confirmed health-buster.

Since nitrosamines are the bad guys and are formed by cooking nitrites at high heat, what are nitrates?

Nitrates are naturally found in many healthy foods like vegetables. They’re especially high in beets. Sometimes our enzymes or gut bacteria change these healthy nitrates into nitrites. However, they rarely form nitrosamines because they’re two steps away from becoming these “bad guys.” Chalk another one up for plant-based eating!

BHA & BHT

Have you seen on products the words “BHA/BHT has been added to the package to help maintain freshness?” Perhaps on cereal packages or in gum? Here’s how they work:

BHA (butylated hydroxyanisole) and BHT (butylated hydroxytoluene) are antioxidants added to many processed foods. The main way BHA and BHT work is by preventing fats from going rancid. Although they’re approved for use as a preservative at small doses, I question their safety and suggest that you do the same. Some studies show they can cause cancer in animals at high doses. Again, they’re added to processed pre-packaged foods, so it’s wise to avoid them nonetheless.

Conclusion

There are a lot of preservatives in our food supply. These compounds work by preventing the growth of bacteria and mold, or by preventing fats from going rancid. And they’re mostly found in processed foods. If you want to avoid them, eat fresh foods.

Does this information make you want to read all of your food ingredient labels from now on? I hope it inspires you to do just that.

What They’re Saying

Teddy and Ryan "Since your class, we've been eating raw and LOVING it! I spend half the time “cooking” and the food is so much fresher and tastier. I've already made the Pesto, Banana Bread, Flax Crackers, Almond Milk, and several other recipes in addition to straight away adding a dehydrator and spiralizer to my kitchen tools. We've both come to the realization that the 30 second gratification of eating a burger doesn't come close to making up for the feeling afterward. Not to mention, we both agree we have not given up any taste what-so-ever and eating/“cooking” has become fun again (we're BOTH actually in the kitchen now at the same time). ...Thank you for such a wonderful class and for re-inspiring my husband and me."

Eric Dowsett "Few people are completely 'holistic' in their approach to healthy living. Madeline has combined many skills and a deep understanding of the nature of how we function and now adds raw 'food lifestyle' to her amazing repertoire to offer a truly 'holistic' approach to health and well-being."
