Coffee Is Super Healthy, Unless You Mess It Up In One of These Three Ways

From a health perspective, coffee has turned a corner and is increasingly recognized as a healthful drink. In addition to being an antioxidant, it’s also linked to a decreased risk for Parkinson’s disease, protecting against type 2 diabetes, improving heart health, and lowering rates of depression in women.

Despite these exceptional health outcomes, there is nothing in this world so wonderful that we can’t come along and totally screw it up. And coffee makes the point. There are three main ways that the benefits of this most deliciously healthy beverage can be undermined.

1. Just Add Milk
The most potent of coffee’s polyphenols is called chlorogenic acid, which is an antioxidant and is also strongly anti-inflammatory. In other words, these polyphenols in coffee can help douse the inflammation in your body that can contribute to everything from cancer, heart disease, diabetes, arthritis, depression and even Alzheimer’s. Its antioxidant action can also help by reducing disease-causing free radicals in the body. 

For these effects to take place, obviously your body must absorb those polyphenols first. However, adding dairy to your morning java decreases your body’s ability to absorb chlorogenic acid. This is likely due to the fact that milk proteins like casein really like to bind to polyphenols. Once bound, your body is not able to absorb them, and then they can’t do you any good any more.

So if you want to downgrade your morning cup of health prevention from Really Good to just So So, you can definitely do that. Just add milk.

2. Just Add Sugar
I spoke to a woman who told me, with a totally straight face, that she put 6 packets of sugar in her coffee every morning. The calorie content of normal coffee is about 4 calories, meaning that this sugar just adds a ton calories. And it’s not just her, as adding gratuitous amounts of sugar to coffee is now quite common. A medium sized cup of the popular caramel macchiato (with its vanilla syrup and caramel) weighs in at 280 calories. Like you need roughly 20% of your entire calorie allotment for the entire day in one morning cup!

Worse though, the consumption of sugar can increase cravings for sweets in the short term (through the over-production of insulin which creates hypoglycemia, leaving you tired and hungry in about an hour and a half). In the long term, sweetened foods also habituate sensory receptors to that level of sugar, so you crave more of it more often. By contrast, the consumption of plain coffee may help lower the amount of food consumed at meals.

So if you want to turn your coffee from something that helps you control calories into something that adds calories, and then creates the short and long term cravings for even more calories, you can definitely do that. Just add sugar.

3. Just Add More
An element of coffee that raises your bad cholesterol (and the LDL which can contribute to artery disease and heart attacks) is present in some coffees but not others. Diterpenes such as cafestol and kahweol are both present in the oil contained within the coffee bean, and these can increase your total cholesterol and LDL levels.

The bad news is that the way the brew is brewed turns out to increase the level of diterpenes, and the highest levels are unfortunately found in the better tasting brewing methods. French Press coffee, for example, has 7.9 mg per cup; Turkish coffee contains 7.8 mg per cup; and espresso produces a level of diterpenes at 3.3 mg per cup. By contrast, the lowest levels are found in more pedestrian brewing methods like instant (0.4 mg per cup), filtered coffee (0.2 mg per cup), and percolated (0.2 mg per cup).

The good news is that to coffee-up your cholesterol to any extent, you would need 5 cups of that French Press or Turkish mud coffee every day. And I know that it’s possible, now that there are colossal swimming pool sizes available, but fortunately most people going for quality are not also going for quantity.

So if you want to increase your coffee-induced bad cholesterol levels, just drink it by the bucket and then add more!
