Thanks for visiting! My goal here is to discuss the latest scientific research to separate the good from all that "guff" in nutritional sciences and all aspects of human health. Because the more you Know, well...the more you Know!

In Case of Emergency, Eat Chocolate

According to the latest study on my favourite health food, 50 g of dark chocolate a couple of hours before a stressful event can blunt the rise in cortisol and epinephrine (stress hormones).

In this new study, Swiss scientists used the commercial dark chocolate “Noir 72%," which contained 125mg of epicatechin per 50 g serving. The researcher recruited 65 healthy men aged 20 - 50 years, and then randomly assigned them to receive either dark chocolate or placebo two hours before the stressful event, which subjected each participant to a mock job interview and a mental arithmetic task in front of an audience.


Pistachios and Body Weight

Many people continue to wrongly assume that consuming nuts, due to their high fat content, causes weight gain. So, in an effort to learn the effects of regular pistachio consumption on body composition and blood lipids in healthy subjects, researchers asked a group of healthy women in their 20s to add a couple servings of pistachios to their daily diets, accounting for up to 20% of their daily calorie needs.


Probiotics for the Common Cold

While most people take probiotics to support their immune system, results from clinical research have been mixed. Of course, considering that about 80% of our immune system resides in the gastrointestinal tract, it makes sense that by improving conditions within the GI tract, the immune system will benefit.


Can Vitamin D Supplements Help Treat Depression?

Here is a quick post on a recent study showing vitamin D's efficacy for treating depression. Up until now, the use of Vitamin D supplements in depression was controversial. Biological flaws in primary studies is a possible reason meta-analyses of Vitamin D have failed to demonstrate efficacy. This newly published systematic review and meta-analysis of Vitamin D and depression compared studies with and without biological flaws.


Gut Bacteria and Multiple Sclerosis

Researchers have recently made some intriguing discoveries about the intestinal microbiome of patients with multiple sclerosis (MS). In this new study, researchers collected foecal samples from 168 MS patients and 43 healthy control patients. The study excluded patients who had recently used antibiotics or probiotics, recently had gastroenteritis, or had a history of inflammatory bowel disease, rheumatoid arthritis, or bowel surgery.

There were no significant differences in dietary patterns between patients with MS and control patients. About 13% of the MS and 24% of the control groups had a history of vegetarian dieting, 52% of both groups had high milk consumption, and 67% of the MS and 48% of control groups had a high level of yogurt consumption.


CoQ10 May Reverse Cognitive Deficits in Menopause

Now, before anyone gets too excited, I have to make it clear that this was just a study on mice, but does add confirmatory evidence to other studies that also suggest CoQ10 has the potential to improve cognition (and not just in menopausal women).

The mechanisms associated with cognitive decline in a post-menopausal state (driven by a loss of ovarian function and reduced estrogen levels) are not well understood. The aim of this present study was to investigate the role of mitochondrial dysfunctions in cognitive impairment in post-menopausal state and to evaluate the protective effect of coenzyme Q10 (CoQ10).


Elder's Vitamin D Status and Cognitive Function

A new prospective cohort study was conducted to examine the relationship between 25-hydroxyvitamin D (25(OH)D) levels (the storage form of vitamin D) and cognitive performance over time in older adults. 2,777 community-dwelling participants aged 70 to 79 (at baseline) in Pittsburgh, Pennsylvania, and Memphis, Tennessee volunteered for the 4-year study.

Vitamin D status was categorized as 25(OH)D levels of less than 20.0 ng/mL, 20.0 to 29.9 ng/mL, or 30.0 ng/mL or greater. Cognition was measured using the modified Mini-Mental State Examination (3MS) and Digit Symbol Substitution Test (DSST).


Brown Fat Induced by Lactate and Ketone Bodies

The presence of brown adipose tissue (BAT) in human adults opens attractive perspectives to treat metabolic disorders. This is because BAT dissipates energy as heat via the uncoupling protein-1 (UCP1). So instead of storing energy (calories from our diet), it's burned off as heat. In fact, this is the basis behind being "warm-blooded" and non-shivering thermogenesis (heat production without the use of shivering).


Fibre Intake Linked to Better Survival After a Heart Attack

Well, last month was the slowest month in terms of new studies I covered--just one! With the CHFA show in Vancouver, then family illnesses, including having the flu myself, this website was neglected. Interestingly, it was still the fourth-best month in the site's history in terms of traffic, so that indicates to me that the site has become a valuable resource for anyone looking recent research on a number of different topics I've covered over the last few years. So I appreciate everyone's support, and I hope to get back into the swing of things here; starting with this new study showing the benefits of fibre consumption after a heart attack.
