Nutritional disorders cause secondary osteoporosis as well as musculoskeletal metabolism dysfunction. The Christian Orthodox Church's fasting in Mediterranean countries such Greece and Cyprus, or M.C.O.C. diet consists of self-restraint from food and/or food categories for 180 ± 19 days of total, especially of animal protein and dairy products. This case-control study attempts to investigate the effect of this fasting pattern on musculoskeletal metabolism and bone density.
One hundred fasters (or M.C.O.C. diet followers; 68 women and 32 men, mean 59 ± 6.5) with 32 years average fasting time and 100 non-fasters (66 females and 34 males, mean 58.1 ± 6.8; the control group of Mediterranean diet followers) over the age of 50, including menopausal women, were interviewed, as well as physically and laboratory examined along with DEXA measurements of the L2-4 vertebrae and hips. Nutrition data gathered through a 3-day food record during a non-fasting period, while energy intakes calculated on a daily food consumption basis.
Given the overall low incidence of osteoporosis in the Mediterranean diet, it appears to be more than three times higher than that of M.C.O.C. diet despite the periodic restriction of food intake of animal origin into a slightly hypothermic pattern, which in turn is characterized by increased consumption of multicolored vegetable foods.
Abstinence from dairy products and meat does not adversely affect musculoskeletal metabolism or bone density. M.C.O.C. diet seems to be "healthy" eating habit for the musculoskeletal system, as future studies expected to confirm.
营养紊乱会导致继发性骨质疏松症和肌肉骨骼代谢功能障碍。在希腊和塞浦路斯等地中海国家的东正教教会禁食或 M.C.O.C. 饮食,即 180±19 天的总禁食期,尤其是限制动物蛋白和乳制品的摄入。本病例对照研究试图探讨这种禁食模式对肌肉骨骼代谢和骨密度的影响。
100 名禁食者(或 M.C.O.C. 饮食追随者;68 名女性和 32 名男性,平均年龄 59±6.5 岁)平均禁食时间为 32 年,100 名非禁食者(66 名女性和 34 名男性,平均年龄 58.1±6.8 岁;对照组为地中海饮食追随者)年龄均在 50 岁以上,包括绝经后妇女,对其进行访谈、体格检查和实验室检查,同时进行 L2-4 椎体和臀部的 DEXA 测量。通过非禁食期的 3 天食物记录收集营养数据,同时根据每日食物摄入量计算能量摄入。
鉴于地中海饮食中骨质疏松症的总体发病率较低,尽管周期性限制动物源性食物摄入至略低温模式,但 M.C.O.C. 饮食的发病率似乎比地中海饮食高三倍以上,而后者的特点是增加了多种颜色的蔬菜食物的摄入。
禁食奶制品和肉类不会对肌肉骨骼代谢或骨密度产生不利影响。M.C.O.C. 饮食似乎是一种“健康”的饮食习惯,未来的研究有望证实这一点。
