The following research included 100.902 Chinese individuals and went on for 7.3 years (Wang X, et.al., 2020).
The study investigated the associations of tea consumption with the risk of atherosclerotic cardiovascular disease and all-cause mortality.
The individuals who drank tea regularly had 1.41 years longer of atherosclerotic cardiovascular disease-free years and 1.26 years longer of life expectancy compared to those who were not regular tea drinkers.
Maybe this does not look like much, but this was from only drinking some tea regularly. The participants were not asked to change any habits at all. If you also consciously make some changes to the food you eat by consuming lower glycemic index meals, you could get additional benefits.
It’s not just about living longer, what’s important is to live without disease and feel good. That is usually what happens when you adapt better habits.
If you don’t like tea, a good alternative is green tea extract. If you take some capsules of green tea extract throughout the day, you could even get more of the beneficial ingredients in green tea than you would get from drinking tea, and that’s extremely easy to do.
