To control blood sugar and cholesterol, Harvard doctor recommends adding one supplement to your morning coffee

In a world overflowing with trendy health powders and overpriced pills, a Harvard doctor is cutting through the noise with one simple recommendation: Psyllium husk. Forget the fads — this quiet, tasteless fibre supplement might just be the most underrated health fix hiding in plain sight. From reducing cholesterol to improving digestion and even lowering the risk of diabetes, Psyllium husk is being backed by science and prescribed by experts. And yet, most of us are missing out on its benefits.

Dr. Trisha Pasricha, a gastroenterologist at Harvard Medical School, in an interview with The Washington Post, said that 96% of people aren't getting enough fibre — a serious problem when it comes to gut health, blood sugar control, and cardiovascular health. For those who can’t meet their fibre goals with whole foods every day, she strongly recommends Psyllium husk as a reliable and effective alternative.




Unlike other fibre supplements, Psyllium stands out for two key reasons. First, when mixed with water, it forms a gel-like substance in the gut that traps bile salts. This forces the liver to draw from blood cholesterol to make more, thereby lowering cholesterol levels over time. Second, once it reaches the colon, Psyllium acts as a prebiotic — feeding beneficial gut bacteria and helping build a healthier microbiome.


Dr. Pasricha advises mixing a tasteless, additive-free Psyllium powder into water or even coffee. No fancy brands needed. And while one major side effect might be more frequent bowel movements — two to three times a day, in fact — she says that’s a sign your body is finally on track.
