Why I Seldom Recommend Vitamins or Supplements
By HANS DUVEFELT
People here in northern Maine, as in my native Sweden, don’t get a whole lot of natural sunlight a good part of the year. As a kid, I had to swallow a daily spoonful of cod liver oil to get the extra vitamin D my mother and many others believed we all needed. Some years later, that fell out of fashion as it turned out that too much vitamin A, also found in that particular dubious marine delicacy, could be harmful.
This is how it goes in medicine: Things that sound like a good idea often turn out to be not so good, or even downright bad for you.
Other vitamins, like B12, can also cause harm: Exce...

In conclusion, we showed that addition of resistance exercise training, but not dietary EAAs, to the myostatin inhibition further increased muscle mass through the attenuation of muscle protein breakdown with proportionate improvements in muscle strength. Interestingly, addition of dietary EAAs to the myostatin inhibition with or without resistance exercise training improved muscle quality. Thus, dissection of the underlying mechanisms behind the combined positive effect of dietary EAAs and resistance exercise training on muscle mass and quality can shed light on the discovery of effective therapeutics against muscle wasti...

On Balance, Vegetarians Exhibit Better Biomarkers than Non-Vegetarians
There is a fair amount of epidemiological data to suggest that vegetarians have, on balance, better long-term health prospects than people who consume meat. The usual caveats apply, in that vegetarianism in many wealthier study populations is correlated with a range of other potentially relevant line items, such as education, wealth, and better lifestyle choices. Further, the average vegetarian may well be mildly calorie restricted in comparison to the average meat eater, and that may be enough in and of itself to explain health effects. Other suggested contributing factors include dietary advanced glycation end-products, ...

This study suggests that some of those changes contribute to age-related hypertension, providing yet another reason to put resources into the near term development of therapies that can reverse the aging of the gut microbiome, such as flagellin vaccination or fecal microbiota transplantation.
"Previous studies from our lab have shown that the composition of the gut microbiota in animal models of hypertension, such as the SHRSP (spontaneously hypertensive stroke-prone) rat model, is different from that in animals with normal blood pressure. Further, transplanting dysbiotic gut microbiota from a hypertensive animal ...

An Assessment of Various Lifestyle Interventions to Treat Sarcopenia
In this study, we performed secondary analyses of data in a randomized controlled trial of multi-domain lifestyle interventions (6-month duration physical exercise, nutritional enrichment, cognitive training, combination and standard care control) among 246 community-dwelling pre-frail and frail elderly, aged ≥65 years, with and without sarcopenia.
We observed that multi-domain physical, nutritional, and cognitive interventions among pre-frail and frail older adults were associated with favorable changes in sarcopenia and blood biomarkers underlying the muscle mass and physical functional response to intervention...

VITAL trial on vitamin D
Role of vitamin D in cardiovascular disease has been suggested by observational studies. Low blood levels of vitamin D was found to be associated with higher risks of heart disease, stroke, hypertension and diabetes mellitus [1]. But the 2011 Institute of Medicine (United States) guidance concluded that the evidence is inconsistent and inconclusive, not meeting the criteria for a cause effect relationship [2].
VITAL study was a randomized placebo controlled trial of vitamin D3 (cholecalciferol) at a dose of 2000 IU per day and omega-3 fatty acids at a dose of 1 g per day for prevention of cancer and cardiovascular diseas...

Do vitamin D, zinc, and other supplements help prevent COVID-19 or hasten healing?
In this study, people whose symptoms did not require hospital admission were randomly assigned to receive
only vitamin C, 8,000 mg/day (the recommended daily amount is 75 mg/day for women and 90 mg/day for men)
only zinc, 50 mg/day (the recommended daily amount is 8 mg/day for women, 11 mg/day for men)
both supplements at the doses above
neither supplement.
The researchers found that people receiving the supplements, whether individually or combined, had no improvement in symptoms or a faster recovery when compared with otherwise similar patients receiving neither supplement.
Proponents of melatonin for COVID-19 have enc...

4 essential nutrients — are you getting enough?
The newest dietary guidelines for Americans say that many Americans don’t get enough of four vital nutrients. Over time, a shortfall of these nutrients may affect different aspects of your health, from teeth and bones to your heart, gut, muscles, blood pressure, weight, and more.
What is a nutritional shortfall?
Nutritional advice can be confusing. Eat more of this, less of that. Make sure you get enough — but not too much. It’s no wonder many people have so-called nutritional shortfalls, where their diet lacks sufficient essential nutrients.
So, which nutrients do you really need and how much? And what key nutri...

Could what we eat improve our sleep?
We think of eating a nutritious diet and exercising as healthy behaviors, but sleep is one of the pillars of a healthy lifestyle. Why is this? Sleep sets the stage for our days. If we experience sound sleep for seven to eight hours, we arise energized in the morning. Diet, exercise, and sleep work synergistically, and affect one another. All three can have an effect on our daily well-being and longevity.
To be well and vital and help prevent certain diseases, like obesity, heart disease, high blood pressure, stroke, diabetes, and many other conditions, we need to prioritize sleep. When we make sleep a priority, we can impr...

Correlative Adventures with COVID
By ANISH KOKA
“The patient in room 1 should be a quick one, its an addon, they just need a prescription for ivermectin”
I’m a bit puzzled by this sentence from my assistant doing his best to help me through a very busy day in the clinic that I’m already behind in. I walk into the room, a script pad stuffed into my hand as I enter the room, to meet a very nice couple. The wife sits patiently with hands crossed on the exam table.
“So, you’re here for Ivermectin?”, I ask.
Why yes, a trip to Texas is planned.. COVID is in the air, the internet, and some important people who have ‘inside ...
