“It’s more of a dynamic interaction than one single compound,” Cimperman says. Some people have tried to isolate one element in tea or coffee that they think is the secret to one effect or another, “and then they realize that it doesn’t have the same effect.”
Miller and his colleagues recently looked at signs of heart disease in more than 6,800 people from different backgrounds across the country. About 75% drank coffee, while about 40% reported drinking tea. Drinking more than one cup of tea regularly was linked to less buildup of calcium in arteries that supply heart disease .

Some people’s bodies process coffee differently than others, says Martha Gulati, MD, head of cardiology at the University of Arizona College of Medicine in Phoenix. Meanwhile, a preference for tea over coffee might reflect other healthier behaviors, she says.
Cimperman said drinking tea has been linked to lower risks of cancer and heart disease , improved weight loss, and a stronger immune system . Meanwhile, studies point to coffee as a potential way to head off not just Parkinson’s but type 2 diabetes , liver disease, and heart problems, Cimperman says.

Coffee didn’t have an effect either way on heart disease , but that was significant in itself, Miller says.
In his study of nearly 1,000 patients, Fuchs says, there was a “significant and linear” association between drinking coffee and lower risk of colon cancer returning in those who drank four or more cups a day. “The more coffee they drank, the lower risk of recurrence.” But the researchers aren’t clear on which element of the drink contributed to that result, and there didn’t seem to be any effect from drinking tea, he says.

“I think you can have two or more cups a day without any concern, and certainly that may benefit you,” Fuchs says. But what about for those who don’t drink coffee? “If it was somebody who hates the stuff and asks, ‘Should I drink it?’ I’d say no. I’d counsel them about diet and exercise and avoiding obesity as measures I think would have a similar benefit.”
Researchers say it’s hard to pinpoint exactly how both drinks affect health. Both coffee and tea are “complex beverages” that contain a variety of ingredients. They include caffeine , polyphenols, and antioxidants — compounds researchers are studying for their potential cancer -fighting properties, says Lisa Cimperman, a clinical dietitian at University Hospitals Case Medical Center.
