Is Coffee Good for You? (A Scientific Approach)

Billions of people drink coffee every day, both for the taste and for the energy boost caffeine provides, but what is it actually doing to their bodies?

Several studies have been conducted to answer this question, and so far the results are looking good. 

Coffee Health Benefits 

Coffee has a myriad of health benefits:

1. Coffee Boosts Your Metabolic Rate

Caffeine is used in almost every weight loss supplement, and unlike many of the other ingredients found in those supplements, coffee's there because of real science. I can lower your metabolic rate by 3-11%.

2. Coffee Provides Essential Nutrients

Every cup of coffee contains small amounts of vitamins B2, B3, and B5, as well as the minerals potassium and magnesium. These nutrients are associated with increased alertness, protein digestion, and the health of your hair and nails.

A single cup of coffee only provides a small nutrient boost, but if you're one of those people who drinks 3-4 cups a day, the effect can be significant.

3. Coffee May Lower Your Risk of Type 2 Diabetes

Several studies have shown that regularly drinking coffee may reduce your risk for Type 2 Diabetes by anywhere between 23% and 50%.

4. Coffee May Lower Your Risk of Alzheimer's

Alzheimer's is the most common neurodivergent disease and cause of dementia in the entire world, and coffee can reduce your risk of getting it by up to 65%.

5. Coffee May Lower Your Risk of Parkinson's

Parkinson's is the second most common neurodivergent disease, killing millions of people every year. Studies show  that coffee may be able to reduce your risk of Parkinson's by up to 60%.

Some studies have suggested that coffee may also reduce the risk of stroke and cirrhosis (extreme scarring of the liver), but there isn't much research to back up these claims. Of course, with the ever increasing popularity of coffee in today's fast paced world, we won't be surprised if studies confirm these suspicions soon.

The Negative Side of Coffee

Like anything you consume, coffee can also have negative effects if you drink too much of it. Coffee causes a slight spike in blood pressure, which can be detrimental if you already suffer from high blood pressure.

Drinking too much coffee can also make it difficult for you to sleep properly, especially if you drink it late in the day. The negative effects of sleep deprivation quickly outweigh the positive effects of coffee, so moderation is key. Try to avoid coffee after 1pm and don't drink more than 3-4 cups a day.

You'll also offset the positive effects of coffee if you add too much cream or sugar, so if you want to reap the biggest rewards you should drink your coffee black (or as close to black as you can stomach).

The Verdict

Coffee is excellent for your health, so long as you drink it in moderation and keep cream/sugar/milk to a minimum. Enjoy that morning treat guilt-free!
