How to Upgrade Your Coffee: 7 Science‑Backed Tips from a Harvard Doctor

Coffee lovers, this one’s for you — because your morning brew may do more than just wake you up. According to Trisha Pasricha, MD, MPH, a physician‑scientist at Harvard Medical School, the way you take your coffee (when, how, and with what) can influence your health in meaningful ways. In a social‑media post, she laid out seven scientifically supported tips to upgrade your daily cup.

Here’s a polished narrative summary of her advice — tailored for coffee fans who want the perks and the smart usage.

1. Keep sugar to 1 teaspoon or less

Sweetening your coffee? Good, but moderation matters. Pasricha points to a 2022 study that found those who drank unsweetened coffee had lower mortality risk than non‑drinkers. Interestingly, light sweetening (about one teaspoon) still showed benefits.

Why it works: Excess sugar can offset many of the positive effects of coffee; by limiting sugar, you’re keeping the beverage’s benefits front and centre.

2. Reconsider artificial sweeteners

Many assume switching to artificial sweeteners is the healthier choice — but research tells a more cautious story. A 2022 study noted that artificial sweeteners may negate the positive patterns seen in coffee drinkers who used sugar or no sweetener.

Takeaway: If you’re using sweetener alternatives, be mindful — they’re not always a “free pass”.

3. Avoid ultra‑processed coffee creamers

That flavored creamer might be convenient, but many versions rely on vegetable oils (like palm or soybean) plus added sugars — both of which undermine your coffee’s health profile. Pasricha advises reading labels and opting for simpler additions — like a dash of cinnamon if you crave flavour.

Suggestion: Use real milk or a minimal ingredient creamer rather than one loaded with additives.

4. Use French press and espresso in moderation

If you brew via French press or drink a lot of espresso, take note: these methods produce higher levels of compounds called diterpenes, which can raise cholesterol by interfering with how the liver clears LDL (“bad”) cholesterol. Pasricha says paper‑filtered methods trap more of these compounds.

So: If you love French press, enjoy it — but maybe not all day long, and balance it with filtered coffee.

5. Instant and decaf coffee still yield benefits

Good news for instant coffee fans and those avoiding caffeine: studies show that ground coffee, instant coffee and decaffeinated coffee all deliver similar health benefits. Pasricha explains that instant coffee is simply filtered automatically, and coffee pods often include a filter too.

In short: You don’t lose out if you go decaf or opt for convenience — it can still count.

6. Drink your coffee before noon

Here’s a standout: A 2025 study of over 40,000 American adults found those who consumed most of their coffee before noon had a 16% lower risk of death from all causes compared to those who drank later in the day.

Why? Late‑day caffeine may suppress melatonin secretion by ~30 %, interfering with circadian rhythm and potentially causing inflammation. Drinking early helps avoid that.

Bottom line: Try to get your main coffee intake in the morning rather than stretching it into the afternoon or evening.

7. Plan around your body’s “bowel signal”

Pasricha reminds us that coffee triggers the gastrocolic reflex — when food or a drink enters the stomach, it prompts colon contractions minutes later. Some people feel the urge to go soon after drinking coffee.

Tip: Be aware of your timing and routine so your coffee habit aligns with your body’s rhythm (and your schedule).

Final thoughts

Coffee can be more than just a caffeine fix — when prepared and timed well, it can support your wellness journey. By limiting sugar, avoiding processed additives, choosing filtered brewing methods, enjoying decaf or instant if needed, and preferably drinking earlier in the day, you’re giving your cup of coffee a chance to serve you better.

As always: If you have specific health conditions or dietary concerns, talk to your doctor before making major changes. Pasricha notes that this advice is informative and not a replacement for personalised medical guidance.
