Tea is good. Millions of people with silent killer could live longer if they drank more tea and coffee.

Based on researchers found that swapping sugary drinks for anti-inflammatory drinks could make people live longer.

About 3.9 million Brits have type 2 diabetes, which raises blood sugar levels and can finally lead to heart disease and stroke.

Over a period of 18 years, researchers tracked the drinking habits of more than 15,000 US suffers, with an average age of 61.

The study team found that people who drank more than one fizzy drink a day were a fifth more likely to die early.

But people who drank up to six cups of coffee a day had a 26% lower risk of dying early, while people who drank the same amount of tea had a 21% lower risk.

Experts from Harvard University say that people who chose water (23%) or low-fat milk (12%) also did better.

The team found that people who decided to drink more coffee and tea after being told they had diabetes were 18% less likely to die early.

49 percent of the 15,486 diabetics who died were in the group of 7,638 people. A total of 3,447 people got heart disease.

Dr. Le Ma, a researcher, said, "Coffee has good parts that may help lower inflammation.

"Tea is also a good source of polyphenols, especially catechins, which help fight free radicals and reduce inflammation."

Dr. Le Ma said it was very important for diabetics to choose healthy drinks.

A new study found that drinking two to three cups of most types of coffee every day may protect you from heart disease and an early death.Studies have also shown that drinking 3 to 5 cups of black coffee a day can lower the chance of heart disease, Alzheimer's, Parkinson's, type 2 diabetes, liver disease, and prostate cancer.

But this study, like many others in the past, was just an observational one, so it can't prove a clear link between cause and effect, said Mills, who wasn't part of the study.

The most risk was cut by ground, strong coffee.

The study used information from the UK Biobank, a research database with information about how nearly 450,000 people who did not have arrhythmia or other heart problems at the start of the study liked to drink coffee. They were split into four groups: those who liked caffeinated ground coffee, those who liked decaffeinated coffee, those who liked caffeinated instant coffee, and those who didn't like coffee at all.

Researchers looked at medical and death records after an average of 12.5 years to see if there were any reports of arrhythmia, cardiovascular disease, stroke, or death. After taking into account age, diabetes, ethnicity, high blood pressure, obesity, obstructive sleep apnea, sex, smoking status, and tea and alcohol intake, researchers found that all types of coffee were linked to a lower risk of dying from any cause.

Duane Mellor, a registered dietitian and senior teaching fellow at Aston University Medical School in Birmingham, UK, said in a statement that the fact that both caffeinated and decaffeinated coffee were helpful "might suggest that it's not just the caffeine that could explain any possible risk reduction" He didn't take part in the study.

"The most well-known part of coffee is caffeine, but the drink has more than 100 biologically active parts," said Kistler, who is a professor of medicine at both the University of Melbourne and Monash University.

"It is likely that the non-caffeinated compounds were responsible for the positive relationships seen between coffee drinking, cardiovascular disease, and survival," Kistler said.

The statement said that people who drank two to three cups of coffee a day were less likely to die early than those who didn't drink coffee. The risk of dying went down by 27% when people drank ground coffee, 14% when they drank decaffeinated coffee, and 11% when they drank caffeinated instant coffee.

Not as strong was the link between coffee and a lower chance of heart disease and stroke: Two to three cups of ground coffee a day cut the risk by 20%. The same amount of decaf coffee cut the risk by 6%, and instant coffee cut the risk by 9%.

When it came to how coffee affected arrhythmia, the data changed. Four to five cups of caffeinated ground coffee a day cut the risk by 17%, while two to three cups of instant coffee a day cut the risk by 12%, the statement said.

Coffee can have bad side effects for some people. People who have trouble sleeping or diabetes that isn't under control, for instance, should talk to a doctor before adding caffeine to their meals.

Creedon said that these bad effects "can be especially important for people who are sensitive to caffeine's effects." So, the results of this study don't show that people should start drinking coffee if they don't already or that they should drink more of it if they already do.

Most studies look at the health benefits of black coffee and don't take into account the extra sugars, creams, milks, and processed ingredients that many people add to their coffee.

Mellor said, "A simple cup of coffee with maybe a little milk is very different from a large latte made with syrup and cream."

The way coffee is made can also change its health benefits. Cafestol, a chemical that is in the oily part of coffee, is caught by a filter. Cafestol can raise LDL, or low-density lipoproteins, which are the bad kind of cholesterol.

But you can't get rid of cafestol by making coffee in a French press, a Turkish coffee maker, or by boiling it, as is common in Scandinavia.

And finally, the benefits of coffee don't apply to kids. Even teens shouldn't drink colas, coffees, energy drinks, or any other drinks with caffeine.
