Why The Paleo Diet And Coffee Are Not Friends


Do you enjoy your cup of coffee in the morning?

Indeed, coffee became a morning habit for a lot of us.

But it did not only become a part of our morning ritual but also became a part of our social life. For example, a lot of business lunches are happening at the coffee shop.

Or where do you usually meet with your friends?

Now when it comes to the Paleo Diet principles, coffee is one of the foods that got controversial reviews among the Paleo Diet followers.

The Paleo Diet and coffee consider to be in line with the Paleo Diet principles by ones and goes against the Paleo Diet principles by others.

To find the truth we should not only look at the origin of coffee, its benefits, and negative side effects but also review what the founder of the Paleo Diet says.

What Is Coffee?

You probably know that coffee is grown on the coffee tree.

And the coffee beans are actually the processed and roasted seeds from a fruit, which is called a coffee cherry.

The coffee trees are usually very short (maximum 30 feet – 9 meters).

paleo diet and coffeeThe coffee tree is usually covered with the green and waxy leaves, flowers, green fruit and ripe fruit at the same time.

Surprisingly but it takes a full year for a coffee cherry to mature after first flowering and approximately 5 years to become a fruit that can be used.

Did you know that the coffee trees can live up to 100 years!

Though they provide with the harvest during their first 7-20 years.

Commercially grown coffee is getting cultivated in a region called the Coffee belt (1).

The trees need to have rich soil with mild temperatures, frequent rain, and shaded sun. These are quite specific conditions for the coffee trees to be grown.

In commercial coffee industry, there are two main coffee types – Arabica and Robusta.

Coffee Arabica is one of the most known coffee trees that represents about 70% of the world’s coffee production.

The beans are flatter, longer and contain less caffeine compared with the Robusta.

Arabica coffee trees need a specific environment to grow and for the most part, the ideal terrain for these trees is steep and access to it is difficult.

The trees are less resistant to disease and parasites, therefore, require more job to be done.

Robusta coffee represents only 30% of the world’s coffee market.

Robusta’s coffee beans are rounder, smaller and contain 50-60% more caffeine compared with Arabica coffee beans.

The trees can withstand warmer temperatures and are naturally more resistant to disease and parasites.

Therefore, it is generally cheaper to cultivate Robusta trees.

What Are The Health Benefits of Coffee?

If you love your cup of coffee every morning you will be pleased to find the following top 5 health benefits that coffee can offer:

1. Coffee May Improve Your Energy Level

A lot of us reach out for a cup of coffee to energize ourselves.

Indeed studies show that coffee can actually increase energy level and make you feel less tired (2).

One of the component of coffee that makes us feel more energetic is stimulant called caffeine.

Caffeine has the ability to block an inhibitory neurotransmitter in the brain that leads to a stimulant effect.

Studies show that may improve various brain function such as memory, mood, energy level, reaction time and general cognitive function (3, 4).

2. Coffee May Help You Lose Weight

Caffeine that is one of the main components of coffee was proven to aid fat burning.

Several studies show that caffeine may boost your metabolism by 3-11%%! (5, 6).

3. Caffeine May Improve Physical Performance

Caffeine not only stimulates our nervous system and sends signals to the fat cells to break down fat but also increase Adrenaline levels in the blood (7).

Caffeine makes the fat cells break down body fat and using released into blood free fatty acids as a fuel (8).

4. Coffee Is Rich In Nutrients

Coffee is much more than just a drink we need to have in the morning.

A cup of coffee contains the following micronutrients (9):

  • Riboflavin (Vitamin B2): 11% of the RDA.
  • Pantothenic Acid (Vitamin B5): 6% of the RDA.
  • Manganese and Potassium: 3% of the RDA.
  • Magnesium and Niacin (B3): 2% of the RDA.

The numbers do not look bad for a single drink!

5. Coffee Is A Great Source Of Antioxidants

It is proven that coffee has an enormous amount of antioxidants.

Moreover, studies show that most people get more antioxidants from coffee than both fruits and vegetables (10).

Why Coffee May Not Be Good For You?

As I have mentioned earlier coffee has controversial views not only among the Paleo Diet followers but also among scientists. Here we summarized top 5 negative effects of coffee on the human body:

1. Coffee May Cause Insomnia

paleo diet and coffeeIf you drink coffee very often you probably found yourself in a situation when you have a hard time falling asleep after taking a cup of coffee in the afternoon.

The half-life of caffeine is 6 hours.

Therefore, it takes 6 hours for our body to eliminate half of the coffee effect.

The rule of thumb is to avoid drinking coffee after around 2 pm.

The studies show that drinking coffee later in the day is strongly associated with insomnia, which in its turn may cause other health issues (11).

2. Coffee May Trigger Anxiety

Basically, any drink containing caffeine can be blamed on that. However, it is coffee that we used to drink every day and start our days with.

Caffeine provides with two types of boost: immediate and long-term.

The long-term boost is a concern because it stays in our body as long as caffeine remains in our system.

And it is, even more, a concern for people who drink coffee throughout the day.

The studies show that caffeine may decrease GABA levels, the transmitter that helps to regulate anxiety (12).

Therefore people with the anxiety condition should avoid drinking coffee.

3. Coffee May Induce Your Cravings For Sweets

Studies showed that caffeine may change our taste buds and make sweet things taste less sweet (13).

This finding may offset the benefit of fat burning process that the coffee may offer.

The finding also explains why coffee goes so good with sweet pastry like doughnuts.

4. Coffee May Make GERD worse

Coffee stimulates the secretion of gastric acid that can cause heartburn even if do not suffer from it very often.

It may make the situation much worse if you have Gastroesophageal Reflux Disease (GERD).

5. Coffee Is A Powerful Stimulate

We already know that caffeine is a powerful stimulate.

It stimulates the central nervous system and tends to ward off drowsiness.

A lot of dependent on coffee people reported that coffee does not give them the same amount of boost as it used to be when they started drinking coffee.

Is Coffee Paleo?

When it comes to the Paleo Diet a lot of different authors have contradicting views.

paleo diet and coffeeFor example, Robb Wolf believes that there is nothing wrong with drinking coffee:

“If you truly ENJOY coffee for all of its warm, black deliciousness and you don’t have any compelling health or lifestyle reasons to avoid it, then I am not going to steal your ‘morning thunder.’

Keep on keeping on (with an occasional detox to clean things out).

But, if on the other hand, your coffee needs a mate(s), or you’re using it as a means to function in the AM; take the time to conduct a CSI (Coffee Scene Investigation) (14).”

Now if we come back to the original creator of the Paleo Diet, Loren Cordain, Ph. D, he says that:

“Coffee should be excluded by anyone seeks to achieve the most out of their Paleo lifestyle.

The Paleo Diet focuses on eating nutrient dense, naturally occurring, anti-inflammatory foods that promote overall wellness and sustained levels of energy.

Many people who switch to the Paleo Diet discover that their morning cup of black gold becomes a habit of the past.

If you find yourself having a hard time quitting the coffee ritual, it might be helpful to incorporate moderate amounts of green tea which is slightly higher in antioxidants and contains lower levels of caffeine. (15).”

So answering the question if coffee is Paleo, the answer is – not, coffee is not Paleo.

Final Thoughts

As you can see coffee has its positive and negative effects.

Coffee may offer a lot of health benefits but recent studies also show some concerns about its regular use.

Even though some authors point out that coffee is the Paleo Diet-friendly drink. It is actually not.

The creator of the Paleo Diet believes that coffee should be excluded from the diet as the Paleo Diet focuses on eating nutrient dense, naturally occurring, anti-inflammatory foods that promote overall wellness and sustained levels of energy.

If coffee is something that you cannot imagine your morning, you might want to consider following the Primal diet principles, where coffee plays an important role.
