Yes, your grandmother knew what she was talking about !
If you think about it, hundreds of years ago, all food was organic, no junk food was around, portion sizes were much smaller, not to mention that there were far fewer pesticides and chemicals around.
Some parts of globe got it right, while some didn’t.
Now we call those places Blue Zones.
Ikaria in Greece
Okinawa in Japan
Ogliastra in Sardinia
Loma Linda in California
Nicoya in Costa Rica
Some of the things that they do are:
Low intensity exercise
They eat purple sweet potatoes, soya products and turmeric
Diet rich in vegetables, good fats and low in protein
Above all they don’t overeat and they keep their traditions.
An interesting factor is social integration and cohesion ! Yes, feeling part of something bigger than themselves is one of the most important longevity factors.
I invite you to get connected with your friends, eat only unprocessed food, and above all respect our planet !
