Antioxidant Foods: Protect Your Physical and Mental Health

Antioxidants are just that: they fight (anti) oxidation.

The chemical process of oxidation is like rusting metal. A molecule loses electrons and creates the infamous free radicals. Oxidation is also the reason why apples, bananas, and avocados go brown when the skin is broken, and they’re exposed to air – they’re getting oxidized.

Free radicals in the body cause inflammation and can contribute to diseases like cancers, diabetes, and heart disease (to name a few). And it’s not just in the body, we can have inflammation of the brain too causing a decline in cognitive function contributing to feelings of ANXIETY!

So, the antidote to oxidation is the antioxidant. Vitamins like vitamins A, C, and E are examples of antioxidants and they are neuro-protective. So are other compounds in foods like carotenoids and phenols. These compounds sacrifice their electrons to stop the oxidation process; this is why squirting some lemon juice on your sliced apples, bananas and avocados slows down the browning process.

But don’t think that all oxidation in the body is bad. It’s not. Your body naturally oxidizes compounds all the time when it’s doing healthy things like metabolizing nutrients or exercising.

As with many things in life and health, the key is maintaining a good balance. In this case, as the balance between oxidation and antioxidation.

We can throw off that balance with exposure to too much alcohol, smoking, or environmental pollutants. Even over-exercising or too much sun exposure can create too much oxidation.

The best sources of antioxidants to combat this effect are nutritious whole foods, like colourful fresh produce, e.g., blueberries, green kale, purple cabbage, etc. In fact, the more colourful and darker the plant is, the higher levels of antioxidants it usually has. Chemicals that give the plants their deep colours are often the antioxidants themselves.

 

ANTIOXIDANTS IN FOOD

 

Let me list out a bunch of antioxidants and the foods they’re found in:

  • Vitamin A – Found in liver, dark leafy greens (e.g., kale), orange fruits and veggies (e.g., mangoes, carrots & squashes)
  • Vitamin C – Found in bell peppers, citrus, berries, and leafy greens
  • Vitamin E – Found in leafy greens, nuts (e.g., walnuts), and seeds (e.g., sunflowers)
  • Carotenoids (e.g., beta-carotene, lycopene, etc.) – Found in tomatoes, carrots, squash, sweet potatoes, and salmon
  • Phenols – Found in green tea, black tea, coffee, cocoa, red wine, and berries

Blueberries are probably one of the most studied antioxidant foods. They contain a range of phytochemical (i.e., plant chemical) compounds and are very high in anthocyanins (the blue-coloured compound).

The antioxidant capacity can be measured in a laboratory; this is called the “oxygen radical absorption capacity,” or “ORAC.” And blueberries have one of the highest ORAC levels.

FUN FACT: Some studies estimate that the highest source of antioxidants in the average American is not from berries, it’s from coffee! Can you imagine how much healthier people can be if they added a few more servings of antioxidant-rich fruits and vegetables to their days?

 

CONCLUSION

 

There are antioxidant vitamins (A, C & E) and other antioxidants like carotenoids and polyphenols in food. They’re highest in colourful fruits and vegetables, nuts and seeds, some meats, tea, coffee, and cocoa.

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!

Have you tried genetic testing?

What’s holding you back?
