Sunscreen Chemicals Linked to Male Infertility

A recently published study has shown that certain chemicals used in sunscreens to protect against ultraviolet (UV) rays can impair a man's ability to father children. Earlier research findings from the same Longitudinal Investigation of Fertility and the Environment (LIFE) Study have linked reduced fertility to high cholesterol levels in women and couples and to high concentrations of phthalates and Bisphenol A (BPA) in men.

Now this study adds to a growing list of chemicals used in everyday products that affect not only our environment, but human health too (which is logical since human health is critically dependent on environmental health). This study is released just in time too, since many in Canada will be heading south over the next couple weeks to soak up the sun during the holiday season. Here is more incentive to choose natural alternatives, or better yet stay in the shade (and just top up on vitamin D with just a few minutes daily of sun exposure).

Inhibit Serotonin to Help Burn Fat

A newly published adds more insight into how we can regulate brown fat (brown adipose tissue, or BAT), which was discussed in some detail in my recent book, LIFE - The Epic Story of Our Mitochondria. This study comes out of McMaster University in Hamilton--not too far from me--and suggests we can turn back the clock on the body's metabolism to that of teenagers, when we could eat all the high-calorie junk we wanted, and still stay slim/buff.

Could Alzheimer's Patients Benefit from Marijuana?

It's time to celebrate Chanukah...and smoke your marijuan-ukha

I'm often asked about how marijuana can have such wonderful potential benefits to the brain and cognitive health, when on the surface--from its recreational use and stigma/government propaganda--most people would think it does the opposite. Well, here is a recently published study that shows how it can possibly reduce the risk of Alzheimer's and/or slow it's progression.

In fact, this isn't the first study I covered on this topic, and almost exactly a year ago, I covered another study that suggested marijuana could prevent Alzheimer's, so the evidence is slowly building, and it appears quite positive.

Exercise for Stress-Induced Depression

We all know by now how healthy regular physical activity is. We also know that it's one of the best anti-depressants known, and there are various reasons for its benefits. First are the endorphins, those compounds produced in our body that act as effective pain-killers and responsible for the “runner’s high.” Next, came the endocannabinoids, the pleasure-inducing molecules released during hard exercise that provide benefits to numerous body systems, including the brain.

Now, decades after scientists first speculated on the effects of exercise on the brain, researchers have discovered a new reason to get active: exercise not only feels good, it protects the brain from depression.

Bacterial Influence on the BBB

We now have enough evidence to know that the health of the gut, and more specifically its microbiome, has significant effects on the brain and cognition. Here is a new study that looks at how the intestinal microbiome can protect the brain from toxic substances.

How Alzheimer's can Spread

Here's my last post before the American Thanksgiving, and living in Canada, you can read my old rant on the Black Friday that follows.

Anyway, ok, so here's a short post on a new study I came across that sheds light on how the toxic proteins associated with Alzheimer's--amyloid-beta--and how it gets transmitted.

MCT Oil Helps Prevent Brain Ageing

Here's my first post in almost a couple weeks, and in that time, I had the privilege of being an "expert guest" (I know, sounds special right?) on a couple radio interviews: one on cognitive health and the nutrient called PQQ, and the other one just a couple nights ago on medical marijuana. Part of that interview on marijuana focused on it's incredible therapeutic value for a rare form of epilepsy that a number of children suffer from.

Now to make the transition to today's topic of discussion, another therapy shown to help some individuals with epilepsy is a ketogenic diet and the use of MCT oil (medium-chain fatty acids), which is another less known natural health product that's been gaining traction--especially with respect to Alzheimer's disease.

And just as I've been talking more and more about the benefits of MCT oil, here's a brand new study that shows how great this increasingly popular and healthy oil actually is--and again, it all boils down to mitochondria and cellular energetics, the topic of my recently released book.

In this new study, researchers suggest that signs of brain ageing can be postponed in mice when placed on a high-fat diet using MCT oil. This opens the possibility of treatment of children suffering from premature aging (Cockayne syndrome), but also adults with Alzheimer's and Parkinson's disease.

Zeaxanthin (and Lutein) for Cognitive Enhancement

We should all know by now the value of lutein and zeaxanthin for improving eye health. Recently, new evidence has been suggesting that it's great for cognitive health as well. This newly published study shows lutein and zeaxanthin may boost visual processing speed even in young people at their peak in cognition.

Probiotics for Liver Health

Hey, why not... I'll finish this week with a probiotics/microbiome theme. According to this newly published scientific review, probiotics may have beneficial effects on the prevention--and treatment--of non-alcoholic fatty liver disease (NAFLD) and related conditions.

Dietary Modulation of the Microbiome and Autoinflammatory Diseases

Since the only show I watch is the Bachelor/Bachelorette... :)
...I didn't know about David Garibaldi (was a contestant on America's Got Talent) until my partner showed me some videos. If you don't know who I'm talking about, you got to check him out. There are many portraits he's done, but for this post, I chose a person famously known for one of my favourite subjects.

Check out some of his other videos too. Incredible! Now back to the program...

Just like the last study I posted discussed how the food we eat can alter the intestinal microbiome, here is another one that showed one's diet may alter susceptibility to autoinflammatory bone disease by changing the intestinal bacteria balance.

An Apple a Day, Will Make the Doctors Go Broke.

OMG... almost 2 months of travel for presentations and tradeshows, and now finally back to getting some new studies on this blog!

...and since the last study posted, I got my new iPhone 6. But this post isn't about Apple and my new phone. No. It's about the real apples--the kind you can eat.

Aluminum's Health Risks Summarized in New Systematic Review

So I recently launched my inaugural book, LIFE: The Epic Story of Our Mitochondria, during a presentation to about 150 colleagues at the CHFA East show in Toronto. The event was a big success and I want to thank everyone for their support, glowing reviews, and excitement over the future of mitochondrial medicine.

As you may have guessed from above, the topic of my book is mitochondrial health and cellular energetics. It's an incredibly fascinating area with a tonne of research being published every week. Seriously. I'm talking on average about 300 new peer-reviewed publications (every week) that are in one way or another connected to mitochondria. That's insane! Anyway, I think you'll hear MUCH more about the topic in the near future, so if you want to get your hands on a copy of the book and give yourself a head start in understanding this rapidly growing area, you can buy the book online through these various retailers:
  • Zwell.ca - my exclusive online healthfood retailer for the softcover copy
  • Amazon - where you can also purchase the Kindle ebook version
  • Chapters/Indigo - where you can buy the Kobo ebook version
  • many health food stores across Canada will soon stock the book in their literature section

I mention this since today's new study of discussion partly looked at the mitochondria, in relation to aluminum exposure. So, with that said, let's talk about this new study...

"Low" Doses May Be Effective for Vitamin K2 (as MK-4)

It's been a while since a new vitamin K study has been published. Now here is a study that suggests we can still get the bone benefits of MK-4 (a form of vitamin K2) at much lower doses than previously studied (which was about 45,000 mcg/day, and up to 60,000 mcg/day). For this new study, researchers recruited 15 healthy men (average age of 25) to participate in this newly published non-placebo controlled dose-finding study.

CoQ10 and Low Birth Weight's Future Complications

Those born with low birth weight will typically experience rapid postnatal growth that allows these individuals to catch up to their peers. Although the underlying mechanisms are poorly understood, studies indicate that low birth weight followed by rapid growth increases the risk of cardiovascular-disease (CVD) as adults.

Mitochondria Behind Age-Related Exercise-Induced Fatigability

With age, we tend to see an increase in "fatigability" while the capacity for mitochondrial energy production decreases. Logically, this correlation makes sense; diminished mitochondrial function may contribute to higher levels of fatigability the older we get.

To confirm whether this is truly due to mitochondrial function (or dysfunction as we age), researchers investigated the relationship between fatigability and skeletal muscle mitochondrial function in 30 participants with an average age of 78.5 years. Fatigability was defined using rating of perceived exertion after a 5-minute treadmill walk at 0.72 m/s. Phosphocreatine recovery in the quadriceps was measured using magnetic resonance spectroscopy and images of the quadriceps were captured to calculate quadriceps volume. ATPmax (amount of ATP--the energy currency in cells--replenished per second) and oxidative capacity (the capacity to product energy via aerobic respiration in the mitochondria) of the quadriceps (ATPmax·Quadriceps volume) were calculated. Peak aerobic capacity (VO2peak) was measured using a modified Balke protocol.

Coffee Can Reduce Parkinson's Disease Risk (Depending on Your Genes)

Swedish researchers have discovered the epigenetics of caffeine on Parkinson’s Disease (PD) risk. Epigenetics is the field of study where environmental factors, including diet, can alter the expression of genes (turn them on or off).

The study identified that when combined with a high caffeine intake (over 237.8 mg/day via coffee consumption), those with the CC-type variant of the GRIN2A gene saw a 47% reduction in PD risk. There was a dose-response curve and risk reduction increased to 58% with 200 - 400 mg of caffeine daily, 80% with 400 – 600 mg/day, and leveled off at 79% with  more than 600 mg/day.

Bacopa's Antioxidant Benefits

Here's a new study that adds weight to one of Bacopa's mechanism of action (Bacopa is a botanical used for 1000s of years in traditional medicine in India). Hydrogen peroxide (H2O2), a major free-radical produced during oxidative stress and is toxic to the cells. Hence, H2O2 has been extensively used to study the effects of antioxidant and cytoprotective role of phytochemicals. In this new study, H2O2 was used to induce oxidative stress via free-radical production, and the protective effects of Bacopa were investigated.

New Study: Organic vs. Conventional Foods

The question of whether organically-grown foods offer any nutritional benefit has been hotly debated for many years. In my opinion, this is an issue "developed" by Big Agri and the biotech industries to shift focus from the central environmental issues, and focus on vitamins and mineral content. Of course, one would logically think that organic foods--based on the fact they improve soil conditions--would be more nutritionally sound, but the research has not be convincing (mind you, if you're just looking at vitamins and minerals, your overlooking the 100s of other beneficial compounds in the food).

Probiotics Help to Lower Blood Pressure

A new meta-analysis has shown that probiotics can lower blood pressure to a small--but statistically significant--degree. This is positive news since even a small reduction of blood pressure may have important cardiovascular health benefit.

This new meta-analysis included nine clinical trials with 543 participants. Probiotic species used were varied among the trials, and the studies lasted three to nine weeks.

Feel Pain When Walking? Try Dark Chocolate!

Here's another new study linking to two passions of mine: dark chocolate and mitochondria. Mitochondria are very susceptible to damage from free-radicals, and the primary site for free-radical production in the electron transport chain (the series of complexes in the mitochondria responsible for energy production) is Complex I.

Omega-3s for Mitochondrial Function & Alzheimer's Prevention

Here is a quick post to discuss more reason to take your omega-3 supplements (krill oil, fish oil, etc.) This study investigated the effects of omega-3 fatty acids on mitochondrial function and processing of the amyloid precursor protein (APP) in brains of young and aged mice.

Antioxidants Alter Gene Expression

Here is a new study that confirms what I've been saying about "antioxidants" over the last few years now. Since free-radicals are typically seen as bad (but not always, as I recently discussed HERE), many started pumping themselves full of antioxidants with the assumption they would mop up those harmful molecules. Of course, much of this was based on in vitro studies (test tube or laboratory studies), and most with even a small understanding of the human body would quickly realize that you can't use what happens in a test tube as a reliable indication of what happens in a living biological system.

Melatonin for Diabetes and Weight Loss?

I know most think of melatonin as a sleep aid, and that's mostly right, but it's been studied for far more than that. Take for instance, this newly published animal study that shows it's potential for diabetic patients and as an ingredient for weight loss.

Free-Radicals Extend Life?!

For most, understanding the basics behind the Free-Radical Theory of Ageing would lead you to believe that free-radicals are bad. And for the most part, that's right--free-radicals cause critical damage to membranes, proteins, fatty acids, DNA, etc. However, if you remember me saying that nothing is 100% good and nothing is 100% bad, it's true for free-radicals as well. In fact, this is a significant point of discussion in my soon-to-be-published book (yes, my first book! ...excited!).

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.

Calorie-Restriction May Extend Human Lifespan

Here's a really cool and exciting study that was published last week. If you haven't heard about calorie-restriction, it's the only proven way to extend lifespan across numerous species, from single-celled yeast, to insects (like fruit flies), to rodents (like rats). This is where calorie intake is restricted to about 30-40% less than what you would normally consume if you were able to just eat as much as you desired (while continuing to provide all the necessary nutrients--a key differentiation between calorie-restriction and malnutrition/starvation).

However, confirming that this could happen in humans was a far leap. In 2012, the first long-term study was published on monkeys, which didn't show benefits to calorie-restriction. However, there are reasons for this, and the researchers behind this newly published study suggest that the control group monkeys in the 2012 study were also inadvertently calorie-restricted due to the study's design.

Omega-3s Have Powerful Benefits on Blood Pressure

Before I get to the study, just wanted to quickly remind everyone that Earth Hour is tomorrow. Remember to turn off all lights and unplug non-essential appliances from 8:30 pm to 9:30 pm tomorrow.

Now, here is a newer study published earlier in the month. I didn't cover it here since I wrongly assumed that mass media would have picked this up and made a big deal out of it...but what followed was media silence! That doesn't do much to counter the argument that mass media relies too heavily on Big Pharma's advertising dollars. So here I am, three weeks later, covering an amazing study that should have made headlines everywhere.

Is Alzheimer's Now the 3rd Leading Cause of Death?

A new analysis using US data shows that upwards of 500,000 deaths a year, or more than a third of death in older adults, are due to Alzheimer's disease (AD). According to this, it would make AD the third leading cause of death in the US, after heart disease and cancer! That's a staggering jump over the 80,000 deaths that the Centers for Disease Control and Prevention (CDC) attributed to AD in 2010.

To determine this, the researchers behind the latest analysis used a statistical method called population attributable risk, which estimated the percentage of deaths due to AD that were in excess of what would be expected in participants if they didn't have AD.

Even Decaffeinated Coffee Protects Against Diabetes

Previously, meta-analyses identified an inverse association of coffee consumption with the risk of type 2 diabetes. I covered a couple related studies before:
However, an updated meta-analysis was needed because new studies comparing the trends of association for caffeinated and decaffeinated coffee have since been published.

Physical Activity and CoQ10 Status in our Elders

Here's a quick summary of a study that showed being physically active can impact CoQ10 levels, and of course health conditions linked to CoQ10.

This study involved a group of healthy, community-dwelling elderly people who were divided according to gender and fitness. Results revealed that people with higher levels of functional capacity had lower levels of cholesterol and lipid peroxidation. Further, they had higher levels of CoQ10 in their plasma, and the ratio of CoQ10/cholesterol and CoQ10/LDL were higher as well.

Vitamin D's Mechanism Discovered: How it Affects Mood & Cognition

A new study has discovered how vitamin D has a critical influence on levels of serotonin in the brain and how it may directly effect social behaviours associated with Autism Spectrum Disorder (ASD). This study suggests that sufficient levels of vitamin D are required to produce the neurotransmitter called serotonin in the brain, which shapes the structure and wiring of the brain and influences social behaviour.

Another Study Confirms Pantethine Lowers Cholesterol

Back in 2011, I covered a study that showed pantethine (the metabolically active form of B5) can lower LDL (bad) cholesterol. This study is just more confirmation of that (and other previous studies).

This study investigated the efficacy of pantethine on cardiovascular risk markers in a randomized, triple-blinded, placebo-controlled study, in a North American population with low to moderate cardiovascular disease (CVD) risk. Each volunteer in the study was eligible for statin therapy based on the National Cholesterol Education Program (NCEP) guidelines.

EPA Better than DHA for Cognitive Function

 I'm a few weeks late on this one, but it's a nice study to cover anyway. This study found that omega-3 supplements particularly high in EPA may improve cognitive performance with a reduction in neural activity observed (indicating that the brain didn't have to work as hard).

Omega-3s Can Clear Beta-Amyloid to Fight Alzheimer's

Another new study has shown that supplementation with omega-3 fatty acids could help to prevent and even reverse the progression of Alzheimer’s disease. This study confirms some other studies I've covered,  suggesting that omega-3 fatty acid derivatives stimulate the uptake of amyloid-beta proteins (proteins that are suggested to kill brain cells and form the plaques that are a hallmark of Alzheimer's disease). For your review, here are some previous studies:

Cooked Meat Linked to Alzheimer's

Here's a new study that shows cooking meat at high temperatures, which produces "advanced glycation end products" (AGEs) may increase the risk of developing dementia. The results from this new study suggest that a particular type of AGE may be one possible cause of the accumulation of amyloid plaques that are characteristic of dementia and Alzheimer’s disease.

High Dose CoQ10 for Parkinson's Disease

For those familiar with the use of CoQ10 in Parkinson's Disease, or heard me discuss this during a seminar or presentation, you may remember that the dose for this neurological condition can go as high as 3000 mg per day! One published study even used 3600 mg daily. Comparatively, this study used lower doses, but still in line with most research in this area where the effective dose falls in the 1200-3000 mg/day range.

Vitamin D for Fibromyalgia

Here is a study that shows the potential value of vitamin D against fibromyalgia. In this placebo-controlled study involving 30 women with fibromyalgia, oral supplementation with cholecalciferol (vitamin D3) for 20 weeks was administered with a goal of achieving serum calcifediol between 32 and 48 ng/mL. 

Results found a marked reduction in pain over the treatment period in the group treated with vitamin D, and a significant group effect was found according to visual analog scale scores, which was correlated with scores on the physical role functioning scale of the SF-health survey 36.

Furthermore, "Optimization of calcifediol levels in fibromyalgia had a positive effect on the perception of pain."

Thiamine May Fight Pancreatic Cancer

Ok, so the next few posts are going to be short and sweet. This study was just an in vitro study, but I cover it here since we know the pharmacology/pharmacokinetics of thiamine (vitamin B1). This means it's a relatively smaller step to extrapolate these results to its potential benefit in humans.

This study involved pancreatic cancer cells, and high dose thiamine was found to reduce "cancer cell proliferation by a mechanism similar to that described for dichloroacetate" (DCA). Administration of thiamine was found to exhibit a lower IC50 value, as compared to DCA, and both thiamine and DCA reduced the extent of PDH phosphorylation, reduced glucose consumption, lactate production, and mitochondrial membrane potential, and increases caspase-3 activity.

Basically, this means that thiamine was effective at inhibiting the growth of pancreatic cancer cells.

Omega-3s Help Slow Brain Shrinkage in Elderly

This study reflects the results of another study I covered almost two years ago. In this new study, researchers analysed data from 1,111 women who were part of the Women's Health Initiative Memory Study. Levels of the omega-3 fatty acids, EPA and DHA, were measured in the women's red blood cells (RBC), and brain volumes were measured by MRI eight years later (when the women were an average age of 78).

Heart Patients' Memory Problems

Similar to THIS study I covered last year, another new study is confirming the link between a healthy heart and healthy brain--or more specifically, a bad heart and a bad brain.

In this new study, almost half of the 912 people in the study (with heart failure and who were at least 70 years old) had memory loss--but in most cases, their cardiologists failed to recognize the cognitive impairment.

This Study is Just Nuts

After the back-to-back studies on nuts I covered in November, here is another positive study showing their health benefits. This study's results showed that high tree nut consumption is strongly linked to a lower risk of obesity and metabolic syndrome.

Tree nuts included almonds, Brazil nuts, cashews, hazelnuts, macadamias, pecans, pine nuts, pistachios, walnuts, and even peanuts (which aren't really nuts). Their consumption varied from daily to never, with average consumption being 16 g/day among the highest consumers, and 5 g/day among the lowest.

Father's Health Influences Unborn Child

It's been a slow start to the new year in terms of interesting studies, but I'll send you away on your weekend with this new study. Now, I would guess most will think it's common sense that the mother's health while pregnant will have a significant impact on the health of the child, but this new study shows that the father's health can also impact the unborn child's future health.

Drinking Alcohol Protects Against Multiple Sclerosis

Interesting results from two new studies suggest drinking alcohol may reduce the risk of developing multiple sclerosis (MS). The data for the studies come from 1) the Epidemiological Investigation of Multiple Sclerosis (EIMS) that included 745 patients with MS (cases) and 1761 controls, and 2) the Genes and Environment in Multiple Sclerosis (GEMS) study that had 5874 cases and 5246 controls.

Mom's Prenatal Vitamin D Intake Linked to Child's Muscle Development

Almost 3 years ago, I covered a study that suggested what this new study confirms. This new vitamin D study has linked the maternal blood level of the vitamin (at 34 weeks of gestation) to the child's lean mass and muscle strength at 4 years of age. These new results indicate that exposure to vitamin D during the late stages of pregnancy might influence the child's muscle development.

This may have consequences for a child's health later in their life--because muscle strength peaks in young adulthood before slowly declining in older age. Low grip strength in adulthood has been associated with poor health outcomes including diabetes, falls and fractures.

Antidepressants Linked to Liver Damage

Happy New Year! KnowGuff.com just came off its 2nd best month ever for traffic, and nearing its 3-year anniversary. So I want to say "thanks!" to all my subscribers, regular visitors, and supporters for making this website an increasingly popular resource in the Natural Health Products industry.

As we enter the heart of winter, we have to be mindful of those who experience seasonal affective disorder (SAD). While many may resort to pharmaceutic antidepressants, we have to know the risks involved, and this what I'll base my first post of the New Year on.
