Whole Health Source: Omega-3 Eggs
"Not everyone has access to pastured eggs. "Omega-3 eggs" come from hens fed an omega-3 enriched diet*. Not only do they have a much higher omega-3 content than conventional eggs, they also contain less AA. One study found that omega-3 eggs contain 39% less AA than conventional and organic eggs. Omega-3 eggs were also rich in short- and long-chain omega-3 fats. Omega-3 eggs are certainly not nutritionally equivalent to pastured eggs, but they're a step in the right direction. "

"Is there a whole food more effective than:
* Coenzyme Q10 for supporting heart function?
* Echinacea in enhancing immunity?
* Oat bran in lowering cholesterol?
* St. John’s Wort for treating depression?
* Lutien for preserving vision?
* Milk Thistle in regenerating the liver?
* Insulin for controlling diabetes?
* Is there a food that has been shown to combat cancer in multiple clinical studies?
Hundreds of studies conclude that a little known fruit from Northern China may, in fact do all of the above.
The Goji Berry has been found to be the most nutritionally dense food on earth!"
Vitamin D Newsletter Mar 2006 | Dr. Wactawski-Wende, New England Journal of Medicine, and Ethics
"Good research is good for medicine. The only thing more important than good research is ethical research. The February 16th issue of the New England Journal of Medicine (NEJM) had a research paper on vitamin D and colon cancer. Was it good research? Was it ethical research? At stake are the lives of 36,000 older American women who agreed to participate in the Women's Health Initiative. "
The effects of conjugated linoleic acid on human health-related outcomes
The effects of conjugated linoleic acid on human health-related outcomes.
Tricon S, Burdge GC, Williams CM, Calder PC, Yaqoob P.
Proc Nutr Soc. 2005 May;64(2):171-82. Review.
PMID: 15960862
Conjugated linoleic acid (CLA) is a collective term for a mixture of positional and geometric isomers of conjugated dienoic derivatives of linoleic acid. CLA has received considerable attention as a result of animal experiments that report anti-carcinogenic, anti-atherogenic and anti-diabetic properties, and modulation of body composition and immune function. Several studies of CLA supplementation in human subjects have now been published, but in contrast to animal studies there has been marked variation between reports on the health-related outcomes. The consensus from seventeen published studies in human subjects is that CLA does not affect body weight or body composition. Some detrimental effects of the trans-10,cis-12 CLA isomer have also been reported in terms of altered blood lipid composition and impaired insulin sensitivity. Finally, CLA has only limited effects on immune functions in man. However, there have been reports of some interesting isomer-specific effects of CLA on the blood lipid profile, but not on immune function. These isomer-specific effects need further investigation. Until more is known, CLA supplementation in man should be considered with caution.

NephroPal: Summer vs Winter mode
"My goal is to gather the basic science and apply it to nutrition - NUTRIGENOMICS. What do I mean? How does what we eat signal our genes in the nucleus. By our food choices, we are sending different signals to our genes. High carbohydrate and high fructose intake signals it is summer time and winter is coming -- grow and store the energy (insulin). High fat, low carbohydrate diet with calorie restriction signals our genes that winter is here -- use the stored energy, repair the genes, and slow down growth (i.e. Sirt1/Foxo pathway). The Sirt1/FoxO1 pathway is important as it aids in repairing DNA. Damaged DNA can lead to uncontrolled cellular replication (i.e. cancers). The immune system (phagocytes) has a mechanism to remove old and unwanted cells called apoptosis (cellular death). "
Effects Of Vitamin D Deficiency Amplified By Shortage Of Estrogen
"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.
Health benefits of eating fish far outweigh risks from contaminants, report concludes - theheart.org
October 17, 2006 | Steve Stiles
Boston, MA - A review of the literature on the health effects of dietary fish or fish-oil intake has a reassuring message for seafood lovers, anyone eating fish for health reasons, and perhaps most everyone else [1]. Levels of mercury and other contaminants in commercially bought fish are low, and their potential risks are overwhelmed by likely reductions in cardiovascular mortality, according to a report in the October 18, 2006 issue of the Journal of the American Medical Association.
"The main message is really that everybody should be eating one or two servings of fish or seafood per week for their health," Dr Dariush Mozaffarian (Harvard School of Public Health, Boston, MA) told heartwire.
In his analysis, coauthored with Dr Eric B Rimm (Brigham and Women's Hospital, Boston, MA), regular "modest" intake of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), the two long-chain n-3 polyunsaturated fatty acids (PUFAs) abundant in finfish and shellfish (collectively referred to as "fish" in the article), is associated with a 36% drop in coronary disease mortality (p<0.001) and a 17% fall in total mortality (p=0.046). The n-3 PUFAs, they also conclude, appear to be important to early brain development.
"Potential risks of fish intake must be considered in the context of potential benefits," according to Mozaffarian and Rimm. "Avoidance of modest fish consumption due to confusion regarding risks and benefits could result in thousands of excess CHD deaths annually and suboptimal neurodevelopment in children."
Those potential benefits are immense compared with the highly publicized but apparently low health risks associated with methylmercury, dioxins, and polychlorinated biphenyls (PCBs) that have been found in some fish species, they write. The evidence suggests a potential for neurodevelopmental deficits from early exposure to methylmercury, but the risk is likely diminished by limiting intake of fish with high methylmercury concentrations
Whole Health Source: Palmitic Acid and Insulin Resistance: a New Paradigm
"We've been having an interesting discussion in the comments about a recently published paper by Dr. Stephen C. Benoit and colleagues (free full text). They showed that a butter-rich diet causes weight gain and insulin resistance in rats, compared to a low-fat diet or a diet based on olive oil. They published a thorough description of the diets' compositions, which is very much appreciated!
They went on to show that infusing palmitic acid (a 16-carbon saturated fat) directly into the brain of rats also caused insulin resistance relative to oleic acid (an 18-carbon monounsaturated fat, like in olive oil). Here's a representation of palmitic acid. The COOH end is the acid end, and the squiggly line is the fatty end. Thus it's called a "fatty acid", various forms of which are the fat currency of the body."

Wheat is Invading China
Dr. Michael Eades linked to an interesting study yesterday on his Health and Nutrition blog. It's entitled "Vegetable-Rich Food Pattern is Related to Obesity in China."
It's one of these epidemiological studies where they try to divide subjects into different categories of eating patterns and see how health problems associate with each one. They identified four patterns: the 'macho' diet high in meat and alcohol; the 'traditional' diet high in rice and vegetables; the 'sweet tooth' pattern high in cake, dairy and various drinks; and the 'vegetable rich' diet high in wheat, vegetables, fruit and tofu. The only pattern that associated with obesity was the vegetable-rich diet. The 25% of people eating closest to the vegetable-rich pattern were more than twice as likely to be obese as the 25% adhering the least.
The authors of the paper try to blame the increased obesity on a higher intake of vegetable oil from stir-frying the vegetables, but that explanation is juvenile and misleading. A cursory glance at table 3 reveals that the vegetable-eaters weren't eating any more fat than their thinner neighbors. Dr. Eades suggests that their higher carbohydrate intake (+10%) and higher calorie intake (+120 kcal/day) are responsible for the weight gain, but I wasn't satisfied with that explanation so I took a closer look.

Vitamin D and MS
"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. "

Health Canada Licenced Finger Pulse Oximeters, COPD Pulse Oximeters, Sport Pulse Oximeter.
"Our Finger Pulse Oximeters are high quality, Health Canada licenced finger pulse oximeters suitable for both medical use and use by athletes, pilots or anyone travelling, working or training at high altitudes.
Hypoxia is a pathological condition in which the body as a whole (generalized hypoxia) or a region of the body (tissue hypoxia) is deprived of adequate oxygen supply. Generalized hypoxia occurs in healthy people when they ascend to high altitude, where it causes altitude sickness leading to potentially fatal complications: high altitude pulmonary edema and high altitude cerebral edema. Hypoxia also occurs in healthy individuals when breathing mixtures of gases with a low oxygen content, e.g. while diving underwater especially when using closed-circuit rebreather systems that control the amount of oxygen in the supplied air. A mild and non-damaging intermittent hypoxia is used intentionally by athletes during altitude trainings to develop an athletic performance adaptation at both the systemic and cellular level. A Finger Pulse Oximeter is invaluable for monitoring blood oxygen saturation for these situations."
Whole Health Source: Butter vs. Margarine Showdown
"came across a gem of a study the other day, courtesy of Dr. John Briffa's blog. It's titled "Margarine Intake and Subsequent Coronary Heart Disease in Men", by Dr. William P. Castelli's group. It followed participants of the Framingham Heart study for 20 years, and recorded heart attack incidence*. Keep in mind that 20 years is an unusually long follow-up period.
