Not described typically in scientific articles is the possible contribution of fasting to the wellness added benefits of the Mediterranean diet. What sort of fasting?
“Orthodox Christian holy books advocate a total of 180–200 days of fasting per year. The faithful are advised to keep away from olive oil, meat, fish, milk and dairy goods just about every Wednesday and Friday all through the year. Moreover, there are 3 principal fasting periods per year: i) a total of 40 days preceding Christmas (meat, dairy goods and eggs are not permitted, when fish and olive oil are permitted except on Wednesdays and Fridays), ii) a period of 48 days preceding Easter (Lent). For the duration of Lent fish is permitted only two days whereas meat, dairy goods and eggs are not permitted. Olive oil consumption is permitted only at weekends, iii) a total of 15 days in August (the Assumption) when the very same dietary guidelines apply as for Lent with the exception of fish consumption which is permitted only on August 6th. Seafood such as shrimps, squid, cuttlefish, octopus, lobsters, crabs as properly as snails are permitted on all fasting days all through the year. The Greek Orthodox fasting practices can for that reason be characterized as requiring a periodic vegetarian diet which includes fish and seafood.”
