In chemistry, an amino acid is a molecule that contains both amine and carboxyl functional groups. In biochemistry, this term refers to alpha-amino acids with the general formula H2NCHRCOOH, where R is an organic substituent.[1] In the alpha amino acids,

Vitamin D in pregnancy and lactation: maternal, fetal, and neonatal outcomes from human and animal studies. Kovacs CS. Am J Clin Nutr. 2008 Aug;88(2):520S-528S. Review. PMID: 18689394 Dosing recommendations for women during pregnancy and lactation might be best directed toward ensuring that the neonate is vitamin D-sufficient and that this sufficiency is maintained during infancy and beyond. A dose of vitamin D that provides 25(OH)D sufficiency in the mother during pregnancy should provide normal cord blood concentrations of 25(OH)D. Research has shown that during lactation, supplements administered directly to the infant can easily achieve vitamin D sufficiency; the mother needs much higher doses (100 µg or 4000 IU per day) to achieve adult-normal 25(OH)D concentrations in her exclusively breastfed infant. In addition, the relation (if any) of vitamin D insufficiency in the fetus or neonate to long-term nonskeletal outcomes such as type 1 diabetes and other chronic diseases needs to be investigated.

"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!"

High dietary methionine intake increases the risk of acute coronary events in middle-aged men. Virtanen JK, Voutilainen S, Rissanen TH, Happonen P, Mursu J, Laukkanen JA, Poulsen H, Lakka TA, Salonen JT. Nutr Metab Cardiovasc Dis. 2006 Mar;16(2):113-20. Epub 2005 Nov 2. PMID: 16487911 doi:10.1016/j.numecd.2005.05.005 Conclusions The main finding of this study is that long-term, moderately high dietary methionine intake may increase the risk of acute coronary events in middle-aged Finnish men free of prior CHD. More prospective research is needed to confirm the role of dietary methionine in the development of CVD, and whether its effects are independent of homocysteine.

Are omega-3 fatty acids options for prevention and treatment of cognitive decline and dementia? Cederholm T, Palmblad J. Curr Opin Clin Nutr Metab Care. 2009 Dec 16. [Epub ahead of print] PMID: 20019606 PURPOSE OF REVIEW: To report recent data on the potential role of omega-3 fatty acids (n-3 FA) found in oily fish, especially docosahexaenoic acid (DHA), to prevent and treat cognitive decline and Alzheimer's disease. RECENT FINDINGS: Observational studies still provide conflicting results, in which the majority indicate beneficial effects on cognition, both when assessed as a continuous variable or as incident dementia, mainly Alzheimer's disease. Experimental studies have demonstrated potentially ameliorating effects of eicosapentaenoic acid (EPA) and DHA on amyloid fragment formation, signal transduction including upregulation of the apolipoprotein receptor SorLA, as well as on angiogenesis. The role of EPA and DHA metabolites on Alzheimer's disease pathology is under investigation. Recently, three randomized intervention studies, with duration up to 6 months have been reported. In contrast to a small study from Taiwan, no positive overall effects were reported from the Swedish OmegAD Study or from a Dutch study, although post hoc analyses indicate that selected individuals with mild forms of Alzheimer's disease or cognitive decline may respond to treatment. SUMMARY: No firm conclusions can be drawn. Based on epidemiological data, fish including oily fish could be advised as part of a balanced diet for public health purpose, although the evidence for better cognition is only fairly consistent. It is unlikely that n-3 FA will emerge as a treatment option in general for improving cognitive function in patients with Alzheimer's disease. n-3 FA, especially DHA, may turn out as an adjuvant therapy in selected cases. Further long-term intervention studies on individuals with mild cognitive reductions are awaite"

"We are fond of grumbling about Britain's grey skies, but there may be a good medical reason for doing so. It seems the dreary weather is bad for our hearts - worse, even, than raised cholesterol and an unhealthy diet. That's the controversial claim being made by Dr David Grimes, a gastroenterologist from Blackburn. He's been gazing at the sky for 20 years for clues about why his patients get more sick than those in the south of the country. And what he's found turns key assumptions about heart disease on their head. 'It's not diet or cholesterol levels that raise your risk of heart disease,' he claims. 'It's where you live. People in the north are more likely to be ill because they get less sunshine Basically they are suffering from 'latitude' sickness. The link is vitamin D. While we get some from our diet, the main source is the sun - sunlight converts a compound in the skin into vitamin D, so the amount you make is directly related to the amount of sunshine you get. In a new book Dr Grimes argues the higher the level of vitamin D in your blood, the lower your risk of heart disease and a range of other illnesses. If he's right, what we need is not diet and lifestyle advice, but food fortified with vitamin D. For years the vitamin was thought to be useful only for preventing rickets. So how does he treat them? 'You can do it with diet,' he says 'One Bangladeshi woman eats oily fish every day and now has a vitamin D blood level of 40. 'We give supplements of 1,000 international units (IU) a day or we can give an injection of 300,000 IU that lasts for a year. 'The patients respond well,' says Grimes 'but what's needed is a proper controlled, long-term trial and who is going to fund that? Not a drug company.'"

Comparison of the Atkins, Zone, Ornish, and LEARN diets for change in weight and related risk factors among overweight premenopausal women: the A TO Z Weight Loss Study: a randomized trial. Gardner CD, Kiazand A, Alhassan S, Kim S, Stafford RS, Balise RR, Kraemer HC, King AC. JAMA. 2007 Mar 7;297(9):969-77. Erratum in: JAMA. 2007 Jul 11;298(2):178. PMID: 17341711 Conclusions In this study, premenopausal overweight and obese women assigned to follow the Atkins diet, which had the lowest carbohydrate intake, lost more weight and experienced more favorable overall metabolic effects at 12 months than women assigned to follow the Zone, Ornish, or LEARN diets. While questions remain about long-term effects and mechanisms, a low-carbohydrate, high-protein, high-fat diet may be considered a feasible alternative recommendation for weight loss.

Correlation of symptoms with vitamin D deficiency and symptom response to cholecalciferol treatment: a randomized controlled trial. Arvold DS, Odean MJ, Dornfeld MP, Regal RR, Arvold JG, Karwoski GC, Mast DJ, Sanford PB, Sjoberg RJ. Endocr Pract. 2009 May-Jun;15(3):203-12. PMID: 19364687 Conclusions: Compared with participants in the placebo group, patients in the treatment group showed mild short-term improvement in the overall fibromyalgia impact score, but did not show significant improvement in most musculoskeletal symptoms or in activities of daily living.

"(NaturalNews) The emu, a native of Australia, is a large, ostrich looking bird that doesn't fly. The Australian Aborigines first discovered the benefits of emu oil and have been using it for thousands of years for bone, muscle and joint pain, as an anti-inflammatory and for many skin conditions. The west is finally taking notice of this remarkable oil. Red Meat with No Worries Although a bird, the emu meat is red and a healthy alternative to traditional red meat. It's naturally 97% fat free, high in iron and vitamin B12 and low in calories and cholesterol. As the meat is packaged and sold, the oil is purified and sold separately. Benefits of Emu Oil Emu oil consists of oleic acid (a mono-unsaturated omega-9 fatty acid), linoleic acid (omega-6 fatty acid) and linolenic acid (an omega-3 fatty acid). The benefits are thought to be due to the ability of the oil to deeply penetrate the skin layers. Linoleic acid (omega-6 fatty acid) is believed to ease muscle aches and joint pain. Oleic acid (omega-9 fatty acid) is considered to have local anti-inflammatory effect (similar to ibuprofen). Studies suggest emu oil is bacteriostatic (does not promote growth of bacteria) and hypoallergenic (won`t cause irritation); it does not leave a greasy feel, and it is non-comedogenic, which means it won`t clog pores. Side effects are virtually unknown with emu oil. Several small clinical studies reported successful results for temporary relief of muscle and joint pain, specially related to arthritis. Emu Oil and Burn Wounds A long-term study by Dr. John Griswold, Director of the Timothy J. Harner Burn Center (affiliated with Texas Tech University Medical Center, Lubbock, Texas) in 1995 found that there was statistically significant difference in scar reduction and inflammation of the emu oil treated wounds. Other benefits found from studies from Department of Dermatology, at Texas Medical School in Houston, proved emu oil does not clog skin pores and has anti-aging properties."

Tofu and cognitive function: food for thought. Grodstein F, Mayeux R, Stampfer MJ. J Am Coll Nutr. 2000 Apr;19(2):207-9. Review. PMID: 10763901 In addition, a plausible biologic hypothesis is generally an important part of judging epidemiologic relations. While high tofu intake may lead to lower plasma estrogen levels [12], we do not know how tofu influences estrogen levels in the brain; we also know very little about estrogen effects in men. Furthermore, data have not even consistently indicated that low endogenous estrogen levels are directly related to cognitive function in non-demented subjects [13]. The authors also posit a non-estrogen mediated hypothesis for the effects of tofu, namely that soy inhibits hippocampal tyrosine kinase and may block long-term potentiation (the likely mechanism by which humans learn and remember). Still, considerably more work must be done to substantiate this hypothesis. Finally, the single measures of outcome used in this study may have limited value, as cognitive function and brain structure change over time. Factors which predict these measures at one point may or may not be the same as those which predict decline over time; fundamentally, the public health interest is in preventing cognitive decline, as the steepness of the decline trajectory likely provides an early marker for risk of the more clinically relevant result-dementia.

A prospective nested case-control study of vitamin D status and pancreatic cancer risk in male smokers. Stolzenberg-Solomon RZ, Vieth R, Azad A, Pietinen P, Taylor PR, Virtamo J, Albanes D. Cancer Res. 2006 Oct 15;66(20):10213-9. PMID: 17047087 Higher vitamin D concentrations were associated with a 3-fold increased risk for pancreatic cancer (highest versus lowest quintile, >65.5 versus <32.0 nmol/L: OR, 2.92; 95% CI, 1.56-5.48, Ptrend = 0.001) that remained after excluding cases diagnosed early during follow-up. Contrary to expectations, subjects with higher prediagnostic vitamin D status had an increased pancreatic cancer risk compared with those with lower status. Our findings need to be replicated in other populations and caution is warranted in their interpretation and implication. Our results are intriguing and may provide clues that further the understanding of the etiology of this highly fatal cancer. In conclusion, contrary to expectation, subjects with higher 25(OH)D concentrations were at greater risk for pancreatic cancer compared with those with lower concentrations in our prospective study with long-term follow-up. Caution is warranted in the interpretation and implication of our findings, however, as vitamin D inadequacy is an important public health problem and adequate status is desirable to prevent bone and other diseases (5). Our results, however, are intriguing and may provide clues that further the understanding of the etiology of this highly fatal cancer.

The term disability usually signifies incapacity to exercise all the legal rights ordinarily possessed by an average person. Convicts, minors, and incompetents are regarded to be under a disability.

Relationships especially the long term ones need constant love and attention. Sexual intimacy is the wonderful expression of love and no one can ever deny this. But there are couples which are unable to enjoy sex due to erectile dysfunction and that are what most frustrating for them.

Vitamin D is available naturally in some foods and are often added to food products. But most people get vitamin D from supplements or sunshine. Vitamin D is produced when sunlight on the skin. The term "vitamin" is actually not very precise because vitamin D is more like a hormone. Overdose can occur in almost all the vitamins, but generally harmless.

Benoquin is chemically composed of monobenzone. This active constituent is known as monobenzyl ether of hydroquinone in chemical terms. Benoquin (monobenzone) is known to decrease the pigmentation of the skin and treats the uneven appearance of the skin color. Benoquin helps in vitiligo and improves skin color permanently and quickly.

Food Choices and Coronary Heart Disease: A Population Based Cohort Study of Rural Swedish Men with 12 Years of Follow-up. Sara Holmberg, Anders Thelin and Eva-Lena Stiernström. Int. J. Environ. Res. Public Health 2009, 6(10), 2626-2638; doi:10.3390/ijerph6102626 - published online 12 October 2009 Coronary heart disease is associated with diet. Nutritional recommendations are frequently provided, but few long term studies on the effect of food choices on heart disease are available. We followed coronary heart disease morbidity and mortality in a cohort of rural men (N = 1,752) participating in a prospective observational study. Dietary choices were assessed at baseline with a 15-item food questionnaire. 138 men were hospitalized or deceased owing to coronary heart disease during the 12 year follow-up. Daily intake of fruit and vegetables was associated with a lower risk of coronary heart disease when combined with a high dairy fat consumption (odds ratio 0.39, 95% CI 0.21-0.73), but not when combined with a low dairy fat consumption (odds ratio 1.70, 95% CI 0.97-2.98). Choosing wholemeal bread or eating fish at least twice a week showed no association with the outcome.

Metabolic and physiologic improvements from consuming a paleolithic, hunter-gatherer type diet. Frassetto LA, Schloetter M, Mietus-Synder M, Morris RC Jr, Sebastian A. Eur J Clin Nutr. 2009 Aug;63(8):947-55. Epub 2009 Feb 11. PMID: 19209185 doi:10.1038/ejcn.2009.4 Conclusions: Even short-term consumption of a paleolithic type diet improves BP and glucose tolerance, decreases insulin secretion, increases insulin sensitivity and improves lipid profiles without weight loss in healthy sedentary humans.

What is PāNu? PāNu is an approach to living centered on the thesis that the diseases of civilization are largely related to abandonment of the metabolic conditions we evolved under - what I have termed the "evolutionary metabolic milieu" - EM2. Returning to EM2 is not based on paleolithic food re-enactment. You don't have to eat bugs or wooly mammoths. Unlike many popular "diets", it doesn't require a calculator, or even a recipe book once you learn some basic science about food.

"Researchers at Johns Hopkins are reporting what is believed to be the first conclusive evidence in men that the long-term ill effects of vitamin D deficiency are amplified by lower levels of the key sex hormone estrogen, but not testosterone. In a national study in 1010 men, to be presented Nov. 15 at the American Heart Association's (AHA) annual Scientific Sessions in Orlando, researchers say the new findings build on previous studies showing that deficiencies in vitamin D and low levels of estrogen, found naturally in differing amounts in men and women, were independent risk factors for hardened and narrowed arteries and weakened bones. Vitamin D is an essential part to keeping the body healthy, and can be obtained from fortified foods, such as milk and cereals, and by exposure to sunlight.

"Aug. 31, 2009 -- Eating a Mediterranean-style diet may help people with type 2 diabetes keep their disease under control without drugs better than following a typical low-fat diet. A new study from Italy shows that people with type 2 diabetes who ate a Mediterranean diet rich in vegetables and whole grains with at least 30% of daily calories from fat (mostly olive oil) were better able to manage their disease without diabetes medications than those who ate a low-fat diet with no more than 30% of calories from fat (with less than 10% coming from saturated fat choices). After four years, researchers found that 44% of people on the Mediterranean diet ended up requiring diabetes medications to control their blood sugars compared with 70% of those who followed the low-fat diet. It's one of the longest-term studies of its kind, and researchers, including Katherine Esposito, MD, of the Second University of Naples, say the results "reinforce the message that benefits of lifestyle interventions should not be overlooked.""
