Just a comment:
Monastic life has greatly improved my overall health.
But it took me a long time to really think about food in ayurvedic terms.
According to ancient Indian texts, humankind is meant to eat rice and pulses.
Milk, meat, ghee, oil, white butter, sugar, etc, are âfancy foodsâ. These are the ones we should eat less of.
As long as you eat rice and dahl/beans, and curry in proper proportions, and finer foods less often, you will be fine. If not you need to see a specialist, I canât help you.
This is primary school knowledge that is reflected in the vinaya, not anything special.
Unfortunately, Sri Lankan food in general is high FODMAP, so the diet itself may be working against people in some regions. Fasting itself shouldnât cause gastritisâŚgastritis is a âsee your GPâ type thing as it may be a sign of something more serious.
The diet was plainer in general in the past.
Also, educated people didnât sleep during the day.
There were (and are) various chores like foot travel, walking places, washing, getting wood and water, etc. And also using less furniture did and does improve flexibility. The point is to do a variety of things that require different motions.
Additionally, if you wear less clothes*, you burn calories heaps faster & get something called âbrown fatâ. This is easy to do as a monk/nun! Actually, 3 robes is a lotâŚJesus wore two robes & said if someone takes your upper robe, give them your sanghati too!
The way people thought about âhealthâ in the ancient world was more about not becoming âsoftâ by getting too reliant on creature comforts like beds, vehicles and furniture. So the Buddha gave us many, many ways to be healthy⌠as long as we donât deliberately ignore them with modern hubris or customary excuses. That is the purpose of the dhutangas, too: to live a simple and healthy life. Itâs not even compulsory in Buddhism to lie down if you donât want to, which is definitely an exercise in itself.
As a monastic, I feel grateful to be closer to the languages and cultures of Indian and ayurvedic medical knowledge. I am grateful to Buddhism and the Buddha for keeping me healthy (as well as to my GP and physio). A lot of the things my physiotherapist tells me about joint health are already in Buddhism, for example.
I think it is wrong for people to get the impression that monastic life is inherently unhealthy. Celibacy and intermittant fasting are two of the best things you can possibly do for yourself. Those and staying away from the computer. All things I can truly recommend & that monastic life has given me.
*to a point. Beyond that point is only hypothermia.
