Coffee – Who can drink it and who should avoid it?

 

Coffee is one of those things – you either love it or hate it. You know if you like the taste or not (or if it’s just a reason to drink sugar and cream). You know how it makes you feel (i.e. your gut, your mind, etc.).

Not to mention the crazy headlines that say coffee is great, and the next day you should avoid it!

There is actual science behind why different people react differently to it. It’s a matter of your genetics and how much coffee you’re used to drinking.

NOTE: Coffee does not equal caffeine. Coffee contains between 50-400 mg of caffeine/cup, averaging around 100 mg/cup. Coffee is one of the most popular ways to consume this stimulant. But… a cup of coffee contains a lot of things over and above the caffeine. Not just water, but antioxidants, and hundreds of other compounds. These are the reasons drinking a cup of coffee is not the same as taking a caffeine pill. And decaffeinated coffee has a lot less caffeine; but, it still contains some.

Let’s look at caffeine metabolism, its effects on the mind and body, and whether coffee drinkers have higher or lower risks of disease. Then I’ll give you some things to consider when deciding if coffee is for you or not.

CAFFEINE METABOLISM

Not all people metabolize caffeine at the same speed. How fast you metabolize caffeine will impact how you’re affected by the caffeine. In fact, caffeine metabolism can be up to 40x faster in some people than others.

About half of us are “slow” metabolizers of caffeine. We can get jitters, heart palpitations, and feel “wired” for up to 9 hours after having a coffee. The other half is “fast” metabolizers of caffeine. They get energy and increased alertness and are back to normal a few hours later.

This is part of the reason those headlines contradict each other so much – because we’re all different!

THE EFFECTS OF COFFEE (AND CAFFEINE) ON THE MIND AND BODY

NOTE: Most studies look at caffeinated coffee, not decaf.

The effects of coffee (and caffeine) on the mind and body also differ between people; this is partly from the metabolism I mentioned. But it also has to do with your body’s amazing ability to adapt (read: become more tolerant) to long-term caffeine use. Many people who start drinking coffee feel the effects a lot more than people who have coffee every day.

Here’s a list of these effects (that usually decrease with long-term use):

  • Stimulates the brain
  • Boosts metabolism
  • Boosts energy and exercise performance
  • Increases your stress hormone cortisol
  • Dehydrates

So, while some of these effects are good and some aren’t, you need to see how they affect you and decide if it’s worth it or not.

COFFEE AND HEALTH RISKS

There are a ton of studies on the health effects of coffee, and whether coffee drinkers are more or less likely to get certain conditions.

Here’s a quick summary of what coffee can lead to:

  • Caffeine addiction and withdrawal symptoms (e.g. a headache, fatigue, irritability)
  • Increased sleep disruption
  • Lower risk of Alzheimer’s and Parkinson’s
  • Lower risk of developing type 2 diabetes
  • Lower risk of certain liver diseases
  • Lower risk of death (“all cause mortality”)
  • Mixed reviews on whether it lowers risks of cancer and heart disease

Many of the health benefits exist even for decaf coffee (except the caffeine addiction and sleep issues).

What’s super-important to note here is that coffee intake is just one of many, many factors that can affect your risks for these diseases. Please never think regular coffee intake is the one thing that can help you overcome these risks. You are health-conscious and know that eating a nutrient-rich whole foods diet, reducing stress, and getting enough sleep and exercise are all critical things to consider for your disease risk. It’s not just about the coffee.

SHOULD YOU DRINK COFFEE OR NOT?

There are a few things to consider when deciding whether you should drink coffee. No one food or drink will make or break your long-term health.

Caffeinated coffee is not recommended for:

  • People with arrhythmias (e.g. irregular heartbeat)
  • People who often feel anxious
  • People who have trouble sleeping
  • People who are pregnant
  • Children and teens

If none of these apply, then monitor how your body reacts when you have coffee. Does it:

  • Give you the jitters?
  • Increase anxious feelings?
  • Affect your sleep?
  • Give you heart palpitations?
  • Affect your digestion (e.g. heartburn, etc.)?
  • Give you a reason to drink a lot of sugar and cream?

Depending on how your body reacts, decide whether these reactions are worth it to you. If you’re not sure, I recommend eliminating it for a while and see the difference.

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?
