I'm Dr. Rupi and on this show, I help you feel more in control of your health through food

and lifestyle medicine. Practicing a few simple habits daily can help you think clearer in weeks

and cut your risk of dementia by almost half. The best thing about it, you don't have to change much.

Neuroscientist and professor at the University of Washington, Dr. Tommy Wood, believes that our minds

are capable of so much more and decline is not inevitable with age. Here walk us through three powerful levers,

You'll learn practical tools you can use right away and the habits that I'm prioritizing

in my own life to future-proof my brain. According to the Lantern, 45% of dementia are preventable.

people who had dementia previously, right? They did something wrong, which is absolutely not the

that may be modifiable at either the individual or the population level, you can do some

statistical analyses to estimate if one particular risk factor was completely eliminated from the population,

what proportion of dementias would no longer happen?

And when you look at all the individual percentages, they add up to 45% in the Lancet Commission

report. So it's like 7% based on education. And then two or three

percent based on individual things like obesity, high blood pressure, hearing loss, brain trauma,
