What’s the first thing that comes to mind when you think of coffee? Is it a jolt of energy? A morning non-negotiable? A delicious and decadent indulgence?

While coffee can certainly check all of those boxes, as it turns out, coffee can also have some pretty remarkable health benefits. In fact, your cup of joe might even be able to help you live a longer, healthier life. Let’s dive into some of the research behind coffee’s incredible effects on health and longevity.

So, What Is Actually in Coffee?

The coffee beans you buy at the store are actually a seed from a fruit known as a coffee cherry produced by coffee trees. Once these coffee cherries are harvested, the seeds are removed, dried, and roasted – transforming them into the coffee beans we’re all familiar with.¹ Once these coffee beans are ground and brewed, then voila – you have yourself a delicious cup of coffee.

But what exactly is in your cup of joe? As it turns out, it’s much more than a powerful jolt of caffeine. Coffee is chock-full of some other health-promoting compounds, such as:^2,3,4,5

• Diterpenes (like cafestol and kahweol) that have powerful anti-inflammatory, antimicrobial, and antispasmodic effects
• Antioxidants (like melanoidins, chlorogenic acid, and caffeic acid) that neutralize harmful free radicals
• Tocopherols that encompass the major forms of vitamin E
• Nicotinic acid, which is a type of vitamin B that’s essential for numerous enzymatic reactions
• Heterocyclic compounds, which have potent antioxidant effects

This impressive fusion of health-boosting compounds can add up to some equally impressive health benefits. 

What Are the Health Benefits of Drinking Coffee?

Some of the health benefits that have been linked to regular coffee consumption include:

Increased Insulin Sensitivity

Coffee can reduce your risk of developing insulin resistance and Type 2 diabetes. While researchers still don’t entirely understand how it works, it’s speculated that coffee influences insulin secretion in a few ways:⁶

• Once consumed, the chlorogenic acid found in coffee is transformed into compounds known as quinides which are known to directly impact blood glucose levels. 
• Coffee may also influence levels of the gut peptides glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 that are intricately involved in regulating insulin secretion as well as hunger hormones.
• Coffee may also have prebiotic-like properties, modifying the microbiome and digestion which subsequently affects insulin secretion.

While coffee itself may positively impact insulin sensitivity, it’s important to note that this isn’t the case if you’re consuming coffee drinks that are loaded with sugar and other artificial flavorings.

Better Brain Health

Caffeine and the compounds found in coffee have some impressive neuroprotective effects. Research has found that regular coffee consumption significantly decreases the risk of developing certain neurodegenerative diseases like dementia, Alzheimer’s, and Parkinson’s.⁷

Coffee’s neuroprotective effects come from its concentrated dose of antioxidants and anti-inflammatory compounds. These compounds are able to minimize and reverse inflammation and oxidative stress in your nervous system. This in turn boosts your overall brain health.

Protection Against Liver Disease

Coffee can also promote liver health. Coffee drinkers are more likely to have healthy liver enzyme levels than non-coffee drinkers and are less likely to develop liver disease. 

Thanks to its potent anti-inflammatory effects paired with its hefty dose of caffeine, coffee creates a chemical known as paraxanthine. Paraxathine deters the development of scar tissue that leads to fibrosis of the liver.⁸ In addition, coffee has been found to activate enzymes that enhance your liver’s detoxification capabilities. This allows your liver to function more efficiently while enhancing overall liver health.⁹

Increased Heart Health

Coffee can be particularly beneficial for cardiovascular health, lowering your risk for conditions like heart disease, congestive heart failure, heart attacks, and strokes.¹⁰ Exactly how coffee boosts heart health is partly attributed to its ability to move a type of protein known as P27. 

Coffee is able to amplify the amount of P27 in your cells’ mitochondria – or the energy-generating powerhouse of your cells. This helps your heart cells function better and recover more efficiently.¹¹

All of these impressive benefits add up to one more significant benefit – increased longevity. 

Coffee Drinkers Live Longer

Thanks to coffee’s incredible health-promoting effects and its ability to combat numerous chronic diseases, this beloved beverage can also help you live longer. In fact, numerous studies have consistently found that regular coffee drinkers are likely to live longer than non-coffee drinkers.^12,13,14

There’s no denying that coffee has some spectacular impacts on both overall health and longevity. But the truth is, not all coffee is created equally. 

So, What Is the Healthiest Coffee to Drink?

When it comes to the coffee you drink, quality matters. Mold and other contaminants are common issues in lower-quality coffee brands. So look for coffee that’s organic, specialty-grade, and verified free of contaminants. My favorite brand that checks all 3 of those boxes and taste great is Purity Coffee. 

And as an added bonus, these top-notch coffees also work if you want to tap into all of the health-boosting benefits of coffee in a less conventional way – with coffee enemas. Click here to learn more about the detoxing power of coffee enemas.
