PMID: 18567762
Compared with baseline, serum parathyroid hormone decreased with both fortification (P = 0.003) and supplementation (P = 0.012). These data demonstrate that vitamin D is equally bioavailable from fortified hard cheeses and supplements, making cheese suitable for vitamin D fortification

The effect of fish consumption on plasma lipoprotein subfraction concentrations was studied in 22 men and women (age > 40 y). Subjects were provided an average American diet (AAD, 35% of energy as fat, 14% as saturated fat, and 35 mg cholesterol/MJ) for 6 wk before being assigned to a National Cholesterol Education Program (NCEP) Step 2 high-fish diet (n = 11, 26% of energy as fat, 4.5% as saturated fat, and 15 mg cholesterol/MJ) or a NCEP Step 2 low-fish diet (n = 11, 26% of energy as fat, 4.0% as saturated fat, and 11 mg cholesterol/MJ) for 24 wk. All food and drink were provided to study participants. Consumption of the high-fish NCEP Step 2 diet was associated with a significant reduction in medium and small VLDL, compared with the AAD diet, whereas the low-fish diet did not affect VLDL subfractions. Both diets significantly reduced LDL cholesterol concentrations, without modifying LDL subfractions. Both diets also lowered HDL cholesterol concentrations. However, the high-fish diet significantly lowered only the HDL fraction containing both apolipoprotein (apo) AI and AII (LpAI:AII) and did not change HDL subfractions assessed by NMR, whereas the low-fish diet significantly lowered the HDL fraction containing only apo AI (LpAI) and the large NMR HDL fractions, resulting in a significant reduction in HDL particle size. Neither diet affected VLDL and LDL particle size. Our data indicate that within the context of a diet restricted in fat and cholesterol, a higher fish content favorably affects VLDL and HDL subspecies

Are statins analogues of vitamin D? : The Lancet
Are statins analogues of vitamin D?

There are many reasons why the dietary-heart-cholesterol hypothesis should be questioned, and why statins might be acting in some other way to reduce the risk of coronary heart disease. Here, I propose that rather than being cholesterol-lowering drugs per se, statins act as vitamin D analogues, and explain why. This proposition is based on published observations that the unexpected and unexplained clinical benefits produced by statins have also been shown to be properties of vitamin D. It seems likely that statins activate vitamin D receptors.
Prospective study of serum 25(OH)-vitamin D concentration and risk of oesophageal and gastric cancers - British Journal of Cancer
Prospective study of serum 25(OH)-vitamin D concentration and risk of oesophageal and gastric cancers.

Br J Cancer. 2007 Jul 2;97(1):123-8. Epub 2007 Jun 5.
PMID: 17551495
We prospectively examined the relation between pretrial serum vitamin D status and risk of oesophageal and gastric cancers among subjects who developed cancer over 5.25 years of follow-up, including 545 oesophageal squamous cell carcinomas (ESCC), 353 gastric cardia adenocarcinomas, 81 gastric noncardia adenocarcinomas, and an age- and sex-stratified random sample of 1105 subjects.
We found no associations for gastric cardia or noncardia adenocarcinoma. Among subjects with low vitamin D status, higher serum 25(OH)D concentrations were associated with significantly increased risk of ESCC in men, but not in women. Further refinements of the analysis did not suggest any factors, which could explain this unexpected result.
In conclusion, we found a direct association between higher serum 25(OH)D concentration and increased risk of ESCC in men but not women in a large population-based prospective cohort study from rural China. We found no association with risk of gastric cardia or noncardia adenocarcinoma in either sex. Greater than 50% of our cohort had an inadequate serum 25(OH)D concentration, yet higher concentrations were associated with increased risk of ESCC compared to lower concentrations.
Coconut Oil - American Society for Nutrition
Giving saturated fat another chance.
Saturated fat has long held a bad rep and been noted for its potential to contribute to cardiovascular disease. So you might understand why I was a bit skeptical of all the hype surrounding the supposedly miracle-working power of coconut oil, which is composed of saturated fatty acids. However, if there's one thing I have learned as a nutrition student, it is that research has the potential to change our views as we continue to expand our knowledge and make new discoveries.
Coconut oil may prevent and alleviate disease.
Both research and clinical studies have shown that MCFA may be useful in treating and preventing diseases such as diabetes, osteoporosis, virus-related dieases (mononucleosis, hepatitis C, herpes, etc.), gallbladder disease, Crohn's disease, and cancer. The smaller size of MCFA (compared to LCFA) allows them to be digested more easily, making them ideal for those suffering from digestive diseases. Coconut oil may assist in the absorption and retaining of calcium, thereby benefiting bones.
Coconut oil has antimicrobial, antiviral, and antifungal properties.
Lipid-coated bacteria and viruses contain a lipid coat which encloses their DNA among other cellular materials. When consumed by humans, coconut oil disrupts the lipid membrane, killing the pathogens without damaging the host or harming health-promoting intestinal bacteria. The antimicrobial properties stem from the monoglycerides and free fatty acids (mainly lauric acid and capric acid) that compose coconut oil.
Coconut Oil is the Antiviral of Nature
(NaturalNews) In a time when strange viruses are making headlines around the world, perhaps it's time you knew about the most powerful natural antiviral around: coconut oil. The antiviral activity in coconut oil is unparalleled, even among the most resistant viruses, and the best part is, if it's virgin and organic, there isn't a man-made chemical in the mix.
Think it's too good to be true?
Bruce Fife, C.N., N.D. and author of The Coconut Oil Miracle shares, "Laboratory tests have shown that the MCFAs (medium chain fatty acids) found in coconut oil are effective in destroying viruses that cause influenza, measles, herpes, mononucleosis hepatitis C, and AIDS; bacteria that can cause stomach ulcers, throat infections, pneumonia, sinusitis, urinary tract infections, meningitis, gonorrhea, and toxic shock syndrome; fungi and yeast that lead to ringworm, candida, and thrush; and parasites that can cause intestinal infections such as giardiasis." Sounds like a powerhouse to me.

Ecological studies of ultraviolet B, vitamin D and cancer since 2000.
Grant WB, Mohr SB.
Ann Epidemiol. 2009 Jul;19(7):446-54. Epub 2009 Mar 9. Review.
PMID: 19269856
CONCLUSION: These findings provide strong evidence that vitamin D status plays an important role in controlling the outcome of cancer. Support for the UVB-vitamin D-cancer theory is now scientifically strong enough to warrant use of vitamin D in cancer prevention, and as a component of treatment. More research studies would help to explore whether there are benefits beyond the substantial effects that have been observed.

Evidence for alteration of the vitamin D-endocrine system in obese subjects. - Journal of Clinical Investigation
Evidence for alteration of the vitamin D-endocrine system in obese subjects.
Bell NH, Epstein S, Greene A, Shary J, Oexmann MJ, Shaw S.
J Clin Invest. 1985 Jul;76(1):370-3.
PMID: 2991340
The results provide evidence that alteration of the vitamin D-endocrine system in obese subjects is characterized by secondary hyperparathyroidism which is associated with enhanced renal tubular reabsorption of calcium and increased circulating 1,25(OH)2D. The reduction of serum 25-OHD in them is attributed to feedback inhibition of hepatic synthesis of the precursor by the increased serum 1,25(OH)2D.

There is increasing evidence that urokinase-type plasminogen activator (u-PA) and matrix metalloproteinases (MMPs) play an important role in cancer metastasis and angiogenesis. Inhibition of u-PA and MMPs could suppress migration and invasion of cancer cells. Berberine, one of the main constituents of the plant Rhizoma coptidis, is a type of isoquinoline alkaloid, reported to have anti-cancer effects in different human cancer cell lines. There is however, no available information on effects of berberine on migration and invasion of human tongue cancer cells. Here, we report that berberine inhibited migration and invasion of human SCC-4 tongue squamous carcinoma cells. This action was mediated by the p-JNK, p-ERK, p-p38, IκK and NF-κB signaling pathways resulting in inhibition of MMP-2 and -9 in human SCC-4 tongue squamous carcinoma cells. Our Western blowing analysis also showed that berberine inhibited the levels of urokinase-plasminogen activator (u-PA). These results suggest that berberine down-regulates u-PA, MMP-2 and -9 expressions in SCC-4 cells through the FAK, IKK and NF-κB mediated pathways and a novel function of berberine is to inhibit the invasive capacity of malignant cells.

Am J Clin Nutr. 2004 Jul;80(1):58-63.
PMID: 15213028
Results: The subjects were categorized into 5 egg consumption groups on the basis of their responses to a questionnaire (≥2/d, 1/d, 1/2 d, 1–2/wk, and seldom). There were 69, 1396, 1667, 1742, and 315 women in each of the 5 groups, respectively. Age-adjusted total cholesterol (5.21, 5.04, 4.95, 4.91, and 4.92 mmol/L in the 5 egg consumption categories, respectively) was related to egg consumption (P < 0.0001, analysis of covariance). In women, unadjusted IHD mortality and all-cause mortality differed significantly between the groups [IHD mortality: 1.1, 0.5, 0.4, 0.5, and 2.0 per 1000 person-years, respectively (P = 0.008, chi-square test); all-cause mortality: 14.8, 8.0, 7.5, 7.5, and 14.5 per 1000 person-years, respectively (P < 0.0001, chi-square test)]. In men, egg consumption was not related to age-adjusted total cholesterol. Cox analysis found that, in women, all-cause mortality in the 1–2-eggs/wk group was significantly lower than that in the 1-egg/d group, whereas no such relations were noted in men.
Conclusion: Limiting egg consumption may have some health benefits, at least in women in geographic areas where egg consumption makes a relatively large contribution to total dietary cholesterol intake.

DIETARY RECOMMENDATIONS FOR INTAKE OF LONG-CHAIN n-3 PUFAS
It is clear from the forgoing discussion that long-chain n-3 fatty acids have been proven to be effective in secondary prevention of MI, with a particularly marked effect on sudden death. Thus it would be prudent to advise post-MI patients to increase long-chain n-3 PUFA consumption. Epidemiological studies, studies investigating effects on classic and emerging risk factors and mechanistic studies indicate that long-chain n-3 fatty acids also play a key role in primary prevention. This is supported by studies in animal models, including monkeys. Thus long-chain n-3 fatty acid consumption should be promoted for all individuals especially those at risk of developing cardiovascular disease. This is the reason why a number of organizations have now made recommendations relating to the intake of fatty fish (for example [3]) and of long-chain n-3 PUFAs (Table 6). It is clear that there is a wide gap between current intakes of long-chain n-3 PUFAs and many of these recommendations (Table 6). To meet these recommendations strategies other than increased consumption of fatty fish may be required.
