This one may be obvious, but it's a coffee habit worth noting. One previous study that evaluated 40,000 adults noticed that drinking more than four cups of coffee a day could have negative effects on one's lifespan. However, the scientists that authored the study did note that having 28 cups a week is fine (exactly 4 cups each day of the week), but drinking more than that could result in negative consequences in terms of longevity.


Your coffee order is drowning in sugar.

Have you ever actually looked at the nutrition information for your go-to coffee order? If you're ordering a large caramel latte at your favorite coffee shop, you're likely consuming at least 30 grams of sugar at once—sometimes more at places like Starbucks or Dunkin'.

Studies have shown that eating too much sugar can lead to an early death. And no, it's not due to obesity or weight gain, but the fact that sugar can cause dehydration which can be a symptom of high blood sugar and, left unchecked, can increase your risk of diabetes.

Instead of ordering a sugary latte, why not ask for a regular latte with a small caramel swirl on top? You can mix in the caramel and still get that same great taste, but with significantly less sugar. Or why not make one of these 12 Tastiest Homemade Coffee Drinks From a Nutritionist.


You're adding too much creamer.

Similar to your sugary latte, if you're not careful with your creamer, your coffee at home will also be drowning in sugar. Choosing to use half-and-half or a little milk (or even almond milk) would be a better choice than a sugary coffee creamer. However, if you prefer a sweeter coffee taste, simply be careful when measuring out the amount of creamer you put in your cup.


You're too committed to decaf.

Seems a bit counterintuitive, right? But it's true! One study published by the journal Longevity & Healthspan says caffeine can actually help extend your life span, improve your health, and delay age-associated diseases like Alzheimer's. That's because caffeine can actually help with dietary restriction and reduced insulin signaling.

Just be careful of how much caffeine you consume! Healthline reports that consuming over 1,000 milligrams of caffeine a day can cause negative effects on the body including increased anxiety, insomnia, and digestive issues. Here's Exactly How Much Caffeine Is Too Much Caffeine.
