Prevalence of low serum vitamin D concentration in an urban population of elderly women in Poland. Napiórkowska L, Budlewski T, Jakubas-Kwiatkowska W, Hamzy V, Gozdowski D, Franek E. Pol Arch Med Wewn. 2009 Nov;119(11):699-703. PMID: 19920793 CONCLUSIONS: The prevalence of low vitamin D concentrations in an urban population of elderly women in Poland is very high. Lower vitamin D levels are associated with a higher PTH concentration

"Jan Kwasniewski was born in 1937 in Poland. He graduated from the Military Medical Academy and specialised in Physical Medicine. For many years he worked in the Military Sanatorium in Ciechocinek as dietician where he introduce famous in Poland and at present all over the world his nutritional method which gives the humans good and long health. This method was named "Optimal Diet" which is the cornerstone to the nutritional theory. The principles of the optimal diet at first shock people because the diet recommends eating large quantities of fats along with a radical cut of carbohydrates. The basic premise is that the dieter should keep the proper proportion among the three fundamental nutrients in food: protein, fat and carbohydrates. He found that the ideal proportion is from 1:2.5:0.5 to 1:3.5:0.5 meaning that with every gram of protein 2.5 to 3.5 grams of fat and half a gram of carbohydrates should be eaten. In another words, optimal nutrition is a high fat, low carbohydrate diet. "

"A friend has emailed me the full text of Pawel Grieb's paper documenting a number of physiological parameters of medium to long term Optimal Diet (OD) eaters in Poland, as pointed out by Flo and Stan. There are a few points worth making. The biggest mistake, BTW, is that the authors claim (correctly) that the OD diet aims for >70% fat with (incorrectly) "no restriction on the type of fat (saturated or unsaturated) or cholesterol level". I think they meant that the OD does not ban saturated fats. This is of course true but the impression given is that the OD allows "healthy" fats, which are, of course, inedible. So the heavy emphasis on saturated fats is missed by the paper. A pity, anyone might be left thinking corn oil is a human food... The first positive aspect is that this is a multi author study, eleven authors from several medical centres/unversities. So it's not a one man band case report. I like that. The second is that it is remarkably positive about the findings throughout. Even the elevated LDL cholesterol levels are not taken as extreme and are not trumpeted from the rooftops as the portent of imminent cardiovascular doom. So refreshing!"

"Dr Jan Kwasniewski This Website is dedicated to Dr Jan Kwasniewski who has spent his lifetime developing and using the Optimal Diet bringing health and happiness to many people. Dr Jan Kwasniewski still lives in Poland, he has refused to commercialise his development and is not a very rich person. He does not sell any supplements. Compared with the standards enjoyed by Western medicos he lives a very ordinary, modest life."

Welcome to the English language website for the "Optimal Diet" movement. The Optimal Diet is a dietary model of human nutrition devised and implemented by Dr. Jan Kwasniewski. The Optimal Diet is a movement, which originated in recent years in Poland, and has rapidly spread to a number of countries worldwide, is to improve the well-being, health and biological value of people as individuals, and to correct nutritional mistakes of human kind as a whole, through promotion and implementation of the "optimal" model of human nutrition. Optimal Diet is based on the delivery of the most important nutritional elements, e.g., the most valuable proteins and fats, whilst leaving the body in charge of the distribution of these elements to the most critical areas. The ideal proportion between the main food components of protein, fat and carbohydrates should be in the range of : m m m m 1 : 2.5 - 3.5 : 0.5 In order to work out the correct daily food intake using this proportion, one has to know how many grams of protein needs to be ingested in a day to satisfy body's requirements.

Teenage girls and elderly women living in northern Europe have low winter vitamin D status. Andersen R, Mølgaard C, Skovgaard LT, Brot C, Cashman KD, Chabros E, Charzewska J, Flynn A, Jakobsen J, Kärkkäinen M, Kiely M, Lamberg-Allardt C, Moreiras O, Natri AM, O'brien M, Rogalska-Niedzwiedz M, Ovesen L. Eur J Clin Nutr. 2005 Apr;59(4):533-41. PMID: 15714215 doi:10.1038/sj.ejcn.1602108 CONCLUSION: Vitamin D status is low in northern Europe during winter. More than one-third of the adolescent girls have vitamin D status below 25 nmol/l and almost all are below 50 nmol/l. Two-thirds of the elderly community-dwelling women have vitamin D status below 50 nmol/l. Use of vitamin D supplements is a significant positive determinant for S-25OHD for both girls and women (P = 0.001).
