"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!"

Benefit-risk assessment of vitamin D supplementation.

PMID: 19957164

Conclusion Our analysis suggests that mean serum 25(OH)D levels of about 75 to 110 nmol/l provide optimal benefits for all investigated endpoints without increasing health risks. These levels can be best obtained with oral doses in the range of 1,800 to 4,000 IU vitamin D per day; further work is needed, including subject and environment factors, to better define the doses that will achieve optimal blood levels in the large majority of the population.

No one can dispute that mother's milk is the ideal nutrition, as far as the biochemical composition is concerned. It contains 3 to 11 grams of fat per 1 gram of protein (0.4% unsaturated fat). The conclusion is obvious - if Nature included such a minute quantity of that constituent in such a wonderful food, then we should respect it. Meanwhile, people are being persuaded that plant-derived fats containing polyunsaturated fatty acids which do not exist in mother's milk, are healthy. Nothing is more misleading.

The best are the fats which contain the highest percentage of energy contributing constituents, or in other words, such in which COOH group is attached to the longest fatty acid chain. Short fatty acid chains contain around 30-40% of energy-contributing constituents, the longest ones over 90%.
Long-chain fatty acids fully saturated with hydrogen, yields approx. 10 cal/g when metabolised, the same as petrol. Fat's value as a "fuel" for our body increases with the increase in the amount of hydrogen per gram of carbon in its molecule, with the increase in the energy-contributing constituents.
Chemically, the best are long-chain fully saturated fatty acids, that is to say, solid fats of animal origin. Only fats with the length of the chain above 10 carbon atoms are suitable to be utilised by our cells and tissues without conversion. These fats are directed straight to the blood stream via the lymphatic system, and they do not have to be converted and made suitable by the liver, as is the case with inferior fats (with shorter chains), or all other constituents of consumed and digested foods

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.

You can't have too much of a good thing. Obviously Stephan's recent posts on lard prompted me to put this one up. The imported nutritionist doesn't seem quite as dismissive as you might expect! But notice in the last paragraph that the big bogeyman is protein overload damaging the kidneys! On 60g/d of protein??? Sobor clearly knows nothing about high fat diets, certainly not the one he is commenting so authoritatively about in this case!"

"This website is about Vitamin D and MS

Multiple sclerosis (MS) is a chronic disease of the central nervous system (CNS), with an uncertain cause. Colleen Hayes and Donald Achaeson have suggested that insufficient sunlight exposure and chronic viral infections might be unrelated environmental risk factors for MS. These risk factors may act synergistically to enable the pathogenic autoimmune response.

The prevalence of MS is highest where environmental supplies of vitamin D are lowest. Sunshine enables the production of vitamin D3 (VD3) in the skin. Epidemiological studies have shown that higher vitamin D blood levels are associated with lower risk, less relapses and a slower progression of multiple sclerosis. Higher vitamin D levels can be achieved in part by increased oral intake of VD3.

Optimal health requires serum 25 hydroxyvitamin D levels higher than 20 ng/ml (50 nmol/L) P Lips, 40 ng/ml (100 nmol/L) P Heaney or at least 40 ng/ml (100 nmol/L) R Vieth. "

Optimal serum 25-hydroxyvitamin D levels for multiple health outcomes.
Bischoff-Ferrari HA.
Adv Exp Med Biol. 2008;624:55-71. Review.
PMID: 18348447
DOI: 10.1007/978-0-387-77574-6_5

Recent evidence suggests that higher vitamin D intakes beyond current recommendations may be associated with better health outcomes. In this chapter, evidence is summarized from different studies that evaluate threshold levels for serum 25(OH)D levels in relation to bone mineral density (BMD), lower extremity function, dental health, risk of falls, admission to nursing home, fractures, cancer prevention and incident hypertension. For all endpoints, the most advantageous serum levels for 25(OH)D appeared to be at least 75 nmol/l (30 ng/ml) and for cancer prevention, desirable 25(OH)D levels are between 90–120 nmol/l (36–48 ng/ml). An intake of no less than 1000IU (25 meg) of vitamin D3 (cholecalciferol) per day for all adults may bring at least 50% of the population up to 75 nmol/l. Thus, higher doses of vitamin D are needed to bring most individuals into the desired range. While estimates suggest that 2000 IU vitamin D3 per day may successfully and safely achieve this goal, the implications of 2000 IU or higher doses for the total adult population need to be addressed in future studies.

In conclusion, we still need further studies to evaluate the association of vitamin D insufficiency and cancer incidence and mortality, but the multiple health benefits of vitamin D and the easy, safe and inexpensive way by which vitamin D can be supplemented should already guide current public health strategies to achieve 25(OH)D levels of at least 75 nmol/l (30 ng/ml) in the general population.

Conclusions: SBP is inversely associated with serum vitamin D concentrations in nonhypertensive white persons in the United States. This observation provides a rationale for studies on the potential effects of vitamin D supplementation as a method to reduce SBP in persons at risk of hypertension.

Using these functional indicators, several studies have more accurately defined vitamin D deficiency as circulating levels of 25(OH)D ≤ 80 nmol or 32 µg/L. Recent studies reveal that current dietary recommendations for adults are not sufficient to maintain circulating 25(OH)D levels at or above this level, especially in pregnancy and lactation.
