Food Preservatives

A food preservative is a substance added to foods to make them last longer; to “preserve” them. Preservatives are added to foods that go bad quickly and have found themselves 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 is healthy.

Foods with preservatives are more-processed, less-nutritious foods to begin with – not exactly health foods. So, 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.

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 needed for food preservation as much. 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.”

So, salt is one of those all-too-common food preservatives that most of us will do better with less of.

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 colour 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 (from nitrites) 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.”

BHA & BHT

Have you seen on packages “BHA/BHT has been added to the package to help maintain freshness?” Perhaps on cereal packages or in gum? Guess how these compounds maintain freshness? Because they’re preservatives.

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.Are they safe? Well, they’re approved for use as a preservative at small doses. However, 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.

Recipe (preservative-free): Kale Chips

Serves 4

INGREDIENTS

1 bunch of kale, washed and dried
1 tbsp olive oil
2 dashes sea salt
2 dashes garlic powder

INSTRUCTIONS

Preheat oven to 300F and place a sheet of parchment paper on a baking sheet.

Take the washed and dried kale and rip them into “chip” size pieces and place in a large bowl.  Drizzle with olive oil, salt, and garlic powder. Mix until the kale pieces are evenly covered.

Place kale onto prepared sheet in an even layer. Bake for 10 minutes. Flip over the kale to cook the other sides of the pieces. Bake for another 10 minutes until the edges just start turning brown. Monitor them well, or you’ll have burnt kale chips.

Serve & enjoy!

Tip: You can use any spice, so try onion powder, paprika, or even turmeric.

Ready for the truth no one wants you to know?

There actually IS a secret tool to getting healthier.

Here’s another secret:
It DOESN’T involve giving up treats and wine forever.

In fact, the way I’ve been able to keep my family and I healthy for the last decade has been largely thanks to the 80/20 rule.

This week’s blog (link below) is ALL about moderation. The word you hear SO MUCH, but never really know how to practically include in your life.

Also on the blog, 15 DELICIOUS (and I mean actually delicious) vegetable recipes.

No, I’m not going to tell you to make a plain salad with a drizzle of balsamic vinegar.

Let’s talk about VEGGIES that are delicious and taste like our favourite comfort food.

When we start to rekindle our flame with veggies, we remember how good they can taste and how they make us FEEL.

What’s your favourite FUN way to include veggies in your diet?

I really enjoyed reading your blog on Veggies! I like the different ideas on how to incorporate more veggies. I love grilled veggies the best but also enjoy making casseroles with different veggies! I cant wait to try some of your new veggie recipes....even the butternut smoothie😬!

If you have some nagging symptoms, its possible that theyre related to the foods you eat!

And were not just talking digestive symptoms.

Even things like headaches, joint pain, or eczema can be related to food that youre sensitive to.

How would you find out if there is a food at the root of your issue?

Through an elimination diet!

Elimination diets are just that - eliminating certain foods. Then you reintroduce them back one at a time to see if you are sensitive to those foods.

It’s a strategic process that can be great… but also not so great.

In this weeks blog - link below - I share the pros and cons of elimination diets and my latest recipe - youll never know that it eliminates the most common allergens (because its so good).

Did you know that your morning coffee can be HARMFUL to your health based on your genetics?

Have you ever wanted to know what you should and shouldn’t eat, based on YOUR specific body?

Todays blog - link below - is ALL about the details of DNA testing AND how to get started.

It looks at your genes and how your diet interacts with them.

We can use nutrition to create PERSONALIZED diets to:

PREVENT certain conditions

Help you understand your INTOLERANCES

Know how your body REACTS to carbs, fats, proteins, vitamins, and minerals

Build a nutrition plan for OPTIMAL health

 

🙋🏻‍♀️ I know I carry the CT variant of the GLUT2 gene.

This means I have a higher risk of sugar addiction which can lead to developing Type II Diabetes – but it doesn’t mean I WILL develop diabetes. 

 

Ive been able to ALTER and IMPROVE my diet with this knowledge to make sure I live a long and healthy life.

 

So, let’s get started figuring YOUR genetics and health out!
