Many people complain of frequent colds and upper respiratory infections. Perhaps even every month. This is an especially big problem for those suffering from chronic sinusitis, because every cold and sore throat also leads to a sinus infection. So a goal is to try to reduce the number of infections, and daily vitamin D supplements may be the answer.

Many studies have looked at vitamin D supplementation, at all sorts of doses, for all sorts of health conditions, including cancer. Unfortunately, when properly done studies with people randomly assigned to different groups are done, then all sorts of correlations don't hold up, or mixed results. Right now it appears that the main positive benefit of vitamin D supplements is lowering the incidence of upper respiratory illnesses that a person gets. Another study just confirmed this finding.

An international team of researchers reviewed data from 43 studies (48,488 participants), and found a small but significant protective effect of vitamin D supplementation in lowering the risk of getting a respiratory infection (when compared with a placebo). The studies revealed that the protective benefits of vitamin D supplements were strongest in 1 to 16 year olds who took between 400 to 1000 IU daily for up to 12 months.

Interestingly, and this may really bother high dose vitamin D advocates, the researchers found that lower doses (400 to 1000 IU daily) had a positive health effect, but NOT larger daily doses. They found that data from 4 recent good studies (with persons randomly assigned to different groups) in which vitamin D was given at daily dose equivalents of 2000 IU/day or more for 2 to 5 years had NO EFFECT. In other words: null data.

These differing findings suggest that frequency (daily is better then weekly or monthly), dose, and duration (no more than 12 months) of vitamin D supplementation are key to its protective effects against respiratory illnesses. It is unclear why higher doses are NOT protective, while smaller doses are protective. It's like the saying: Less is more.

Excerpts from Medical Xpress, which actually is misleading in how the conclusions of the study are described: New research on vitamin D and respiratory infections important for risk groups

Studies have shown that supplementary vitamin D seems to provide a certain degree of protection against respiratory infections. A new study involving researchers from Karolinska Institute has now made the most comprehensive synthesis to date of this connection. The study, which is published in The Lancet Diabetes & Endocrinology, confirms that vitamin D protects against respiratory infections, a result that can have significance for the healthcare services. [NOTE: Protective effect was seen in the 1 to 16 year old age groups, and not other age groups.] ...continue reading "Fewer Respiratory Infections With Vitamin D Supplements"

Covid-19 infections are linked to many long-term health problems, but now a surprising one - an increased risk for erectile dysfunction in sexually active men. University of Rome researchers found that the risk of developing erectile dysfunction (ED) increased six-fold after a COVID-19 infection. They also found that a person who already has erectile dysfunction is at five times higher risk for a COVID-19 infection.

They thought that erectile dysfunction after COVID-19 could be either a short or long-term effect  - meaning it might or might not go away over time.

Why would a coronavirus infection lead to erectile dysfunction? Evidence is finding that even "silent" asymptomatic COVID-19 infections may have an effect on small blood vessels so that there is endothelial dysfunction, which is impaired functioning of the inner lining of blood vessels. This means that arteries and arterioles are unable to dilate fully, and so blood supply to the penis can be blocked or narrowed.

Erectile dysfunction (ED) has been often considered a sign (a hallmark) of endothelial dysfunction. Higher rates of erectile dysfunction occur among men suffering from hypertension, obesity, diabetes, and heart disease.

The University of Rome researchers summed it up as get vaccinated or "Mask up to keep it up."

A related finding: Last year a study (conducted in China) that autopsied 12 persons who had died of COVID-19 found that they had damage in the testicles - with inflammation, fluid accumulation, and reduced numbers of Leydig cells (which normally produce testosterone).

Excerpts from Medscape: Risk for Erectile Dysfunction Sixfold Higher in Men With COVID-19

COVID-19 increases the risk of developing erectile dysfunction (ED) by nearly sixfold, according to data from the first study to investigate the association between ED and COVID-19 in young men in a real-life setting. ...continue reading "COVID-19 Infection Linked to Increased Risk of Erectile Dysfunction"

Back in 2017 the world was shocked by a major study that focused on dropping sperm counts in men living in Western countries - a drop of over 50% in 4 decades, or about 1% per year. Along with an increase in infertility. If the drop in sperm counts continues at its current pace, it ultimately means that humans soon will not be able to reproduce. Worse case scenario: extinction of humans.

Dr. Shanna Swan, who an author of the study, has a just published an excellent eye-opening book about this topic. The cause for these sperm count drops and increasing infertility are the hormone (endocrine) disrupting chemicals in everyday products all around us. In plastics, in many pesticides, in personal care products, in our foods (from the packaging)... Yes, all around us. It turns out these chemicals have all sorts of harmful health effects, not just lowering of sperm counts and increasing infertility. [see below]

Good news: we can't escape all the harmful chemicals around us, but we can really decrease our exposures and so decrease the levels of these chemicals in our bodies. And it's better for our health! For tips on ways to reduce your exposures and the levels of harmful chemicals in your body - see Avoiding Harmful Chemicals.

The highly recommended book is written by Shanna Swan, PhD and Stacey Colino: Count Down: How Our Modern World Is Threatening Sperm Counts, Altering Male and Female Reproductive Development, and Imperiling the Future of the Human Race. Scribner, 2020. With many pages of references at the end.

An interesting short interview with Dr. Shanna Swan. From The Intercept: TOXIC CHEMICALS THREATEN HUMANITY’S ABILITY TO REPRODUCE

..a book that ties industrial chemicals in everyday products to a wide range of changes taking place in recent years, including increasing numbers of babies born with smaller penises; higher rates of erectile dysfunction; declining fertility; eroding sex differences in some animal species; and potentially even behaviors that are thought of as gender-typical.

This is now the 9th year of successfully using only probiotics to treat sinusitis - both chronic sinusitis and regular sinus infections. This means no antibiotics or any other antibacterial has been used in more than 8 years! This is amazing – ten years ago I didn't believe this to be possible.

We (myself and family members) have accomplished this by using the amazing probiotic (beneficial bacteria) Lactobacillus sakei. This bacteria occurs naturally (in tiny amounts) in healthy sinuses, but is depleted or missing in those with sinusitis. I started using kimchi back in 2013 after reading research. The last few years I've used the refrigerated product Lanto Sinus, which contains a kimchi-derived strain of Lactobacillus sakei. 

I have heard from hundreds of people since the blog started, and the majority agree - Lactobacillus sakei works great as a sinusitis treatment! (Other probiotic species just don't work.) [See Best Probiotics For Sinusitis for details on results and products used.]

What I've learned about Lactobacillus sakei:

  1. Only use it when needed, when there are some sinus symptoms or you're sliding towards sinusitis. Just like with antibiotics, you shouldn't take it daily and routinely.
  2. Swishing a product like Lanto Sinus in the mouth alone is a gentle and cautious way to use the product. Using it in the nostrils is a stronger way to use the product.
  3. Don't overdo it. Using a little bit in the nostrils (as described in Sinusitis Treatment Summary) is sufficient. Let the little buggers travel on their own throughout the sinuses!
  4. Use for a few days and evaluate whether you can stop or whether you need to keep using it longer. Frequently the sinuses keep improving even after stopping Lactobacillus sakei. One can always use more if needed.
  5. If Lactobacillus sakei works for a person, it can feel miraculous as sinusitis symptoms disappear, frequently within a few days. Others have slower improvement. Unfortunately, it doesn't work for everyone and only self-experimentation determines whether it does - after all, everyone's sinus microbiome is different.
  6. Lactobacillus sakei alone is enough to treat sinusitis. Don't need fancy concoctions or fancy protocols when using it. Using it should take under 1 minute a day!
  7. The sinus microbiome slowly improves, so we are using less and less of Lanto Sinus over time. There have been improvements in the sinuses – for example, this past year my snot is like it used to be decades ago before sinus problems. We are also getting fewer upper respiratory infections.
  8. My sense is that Lactobacillus sakei is colonizing in the sinuses, at least in the short term (weeks or months).

Hopefully this offers hope to sinus infection sufferers.

I also want to mention that I'm a consultant for Lanto Health, but that's because I really like the product and use it whenever needed.

Good health!

Once again a study finds that more exercise and less sitting improves glucose metabolism and so reduces the risk of diabetes. Is anyone surprised anymore by the health benefits of physical activity?

A study conducted in Finland found that in 660 adults 67 to 69 years of age, those who were most active throughout the day had the fewest glucose metabolism disorders (e.g. impaired glucose tolerance) and their insulin sensitivity was better - when compared to less active adults, especially sedentary couch potatoes. The best is to be active and move around a lot during the day, and not just be physically active during a short period.

Other studies find that the prevalence of type 2 diabetes is about twice as common in sedentary adults compared to active older adults. Study after study finds that increasing physical activity (as compared to being sedentary or less active) improves a person's health numerous ways and lowers the risk of all sorts of diseases.

From Medical Xpress: Moderate-to-vigorous physical activity and less sitting reduce the risk of diabetes in older adults

According to a recent study, moderate-to-vigorous physical activity and less sedentary time improve glucose metabolism and reduce the risk of type 2 diabetes in older adults. Based on the results, it is important to encourage older adults to avoid sedentary time and increase moderate-to-vigorous physical activity to improve their glucose metabolism.

Good news for coffee lovers! Drinking 1 or more cups of coffee a day was associated with a reduced risk of heart failure in three large heart disease studies. However, drinking decaffeinated coffee was not.

Researchers analyzed results of the 3 studies, in which more than 21,000 adults were followed at least 10 years. The studies did not differentiate between type of coffee consumed and how it was prepared (drip, espresso, percolated, French press). The researchers point out that other studies have similar findings - that increased consumption of coffee is associated with decreased heart disease deaths or deaths from any cause.

Many studies also find other benefits from daily coffee consumption, such as lowered risk of diabetes, some cancers, and some neurological conditions. However, avoid caffeine when trying to conceive and during pregnancy - then it is associated with harm to the pregnancy and fetus (e.g. with miscarriage, stillbirth, low birth weight and/or small for gestational age).

Excerpts from Science Daily: Coffee lovers, rejoice! Drinking more coffee associated with decreased heart failure risk

Dietary information from three large, well-known heart disease studies suggests drinking one or more cups of caffeinated coffee may reduce heart failure risk, according to research published today in Circulation: Heart Failure, an American Heart Association journal.  ...continue reading "Drinking Coffee Associated With Lower Heart Failure Risk"

Bleeding gums are usually considered a sign of gingivitis, and the typical advice is to brush and floss more. However, new research suggests that bleeding gums can also be due to low vitamin C levels, and that extra vitamin C in the diet or supplements could help reverse the bleeding in these cases.

After reviewing fifteen studies, the authors found that bleeding in the eye (retinal hemorrhaging) and cerebral strokes are associated with an increased tendency for gum (gingival) bleeding, and that vitamin C supplementation (e.g. ascorbic acid) reverses the retinal bleeding associated with low vitamin C  levels in the blood.

These bleeding tendencies may reflect trouble in the person's microvascular system (microvascular fragility), which can be reversed with increased vitamin C (ascorbic acid) intake. [microvascular means the tiny vessels (e.g.venules and capillaries) of the circulatory system.] The researchers point out that current recommended vitamin C (ascorbic acid) doses are enough to prevent scurvy, but may be too low to prevent microvascular fragility.

Getting more vitamin C in the diet is easy to do by eating more fruits and vegetables. Especially high levels of vitamin C are in orange juice, oranges, citrus fruits, kiwis, red peppers, broccoli, strawberries, brussels sprouts, and grapefruit.

From Medical Xpress: Bleeding gums may be a sign you need more vitamin C in your diet

Current advice from the America Dental Association tells you that if your gums bleed, make sure you are brushing and flossing twice a day because it could be a sign of gingivitis, an early stage of periodontal disease. And that might be true. So if you are concerned, see your dentist. However, a new University of Washington study suggests you should also check your intake of vitamin C.  ...continue reading "Bleeding Gums Can Be Sign Of Low Vitamin C Levels"

Have you wondered whether a totally vegan diet for young children is healthy? Are they missing nutrients? A study from Finland attempted to answer this question by comparing young children eating vegan diets with those eating vegetarian and omnivore (both meat and plants) diets. A vegan diet contains no animal products, including eggs and dairy.

The researchers studied 40 healthy Finnish children, average age 3 1/2 years. They found that a vegan diet, even with recommended levels of supplementation (vitamin B12, iodine, vitamin D), resulted in significant effects on the children's metabolism and lower levels of certain nutrients, such as Vitamin A, vitamin D, and retinol-binding proteins (RBP). The vegan children also had a lower protein intake and lower levels of essential amino acids.

A vegan diet is practically devoid of cholesterol, EPA, and DHA, and so the children had significantly lower total cholesterol, HDL, LDL, and DHA (docosahexanoic acid) levels. DHA is a fatty acid needed for development of visual function. The researchers were concerned about the visual health of the vegan children due to the combination of low vitamin A and DHA levels. On the other hand, folate levels were high in the vegan children.

It is interesting that these differences occurred, even though all the children received nutritionist planned daily meals at high quality day care. The intake of vitamins D and A were the same in the different groups. All vegan children had followed a vegan diet since birth and were breastfed for 13–50 months by vegan mothers.

The researchers said that while a vegan diet is generally viewed as having health benefits in adulthood, they have concerns with a vegan diet for young developing children. The vegan children had low cholesterol levels, but the researchers said cholesterol is "essential for cellular growth, division, and development of physiological systems due to its major role in the synthesis of cell membranes, steroid hormones, bile acids, and brain myelin".

We currently don't know long-term health effects (whether good or bad) of a strict vegan diet from birth. Studies are needed! But we do know that young developing children need cholesterol. Another very important nutrient that may be lacking in vegan diets is choline, which is critical for brain health - a good source is eggs.

From Science Daily: Vegan diet significantly remodels metabolism in young children

The study concludes that vegan diet has a broad effect on children's metabolism. Serum biomarker levels for vitamins A and D, cholesterol forms and essential amino acids were significantly lower in children on vegan diet compared to age-adjusted omnivores. In addition, docosahexaenoic acid is absent from vegan diet. The results were recently published in a high-profile international scientific journal EMBO Molecular Medicine.  ...continue reading "Some Concerns With A Vegan Diet In Young Children"

There is strong evidence for a link between the foods a person eats, the microbes that live in the person's gut (gut microbiome), and the person's health, according to a large international study. Yes, it's all related.

The researchers were able to find clear patterns of the types of foods eaten and the microbes in the gut. They found that the presence of 15 specific bacteria are consistently associated with good health ("good microbes") and some other bacteria ("bad microbes") are associated with poor metabolic health (including inflammation, blood sugar control).

Study researcher Tim Spector (of King's College London) said: "When you eat, you're not just nourishing your body, you're feeding the trillions of microbes that live inside your gut."

They found that a diverse diet rich in minimally processed plant-based foods (e.g. fruits, vegetables, seeds, nuts, whole grains, dietary fiber) and fish supports and feeds "good" gut microbes associated with health, with favorable blood sugar levels (glucose control), lower levels of inflammation, improved metabolism, and thus lower risk of heart disease and other chronic conditions (e.g. type 2 diabetes).

On the other hand, persons that ate more highly processed foods, added sugars (desserts!), low fiber foods, artificial sweeteners, foods with additives were more likely to have "bad" microbes linked to poor health, inflammation, unfavorable blood sugar levels, and obesity.

They were able to see that specific foods clearly had an effect on specific bacteria, for example eating tomatoes with an increase in beneficial species of Roseburia. Eating a variety of plant based foods was also associated with an increase in diversity of bacteria (this is considered good), and also with the presence of beneficial keystone bacteria such as  Faecalibacterium prausnitzii.

VERY IMPORTANT: The beneficial bacteria the researchers list are NOT in probiotic supplements. Instead, you must eat a variety of foods that feed beneficial bacteria (e.g. eating a Mediterranean style diet). In fact, some of the microbes the researchers found have not yet been named. Foods also contain bacteria, and these are ingested. For example, an apple contains about 100 million bacteria!

Diets rich in healthy and plant-based foods encourages the presence of gut microbes that are linked to a lower risk of common illnesses including heart disease, research has found.  ...continue reading "Your Diet, Your Gut Microbes, And Your Health"

Well... once again a study found that frequently eating fried food is not good for health - that it is linked to a higher risk of major heart disease and major cardiovascular events (e.g. heart attack, stroke).

Apparently there has been some debate over this issue, so researchers at  Shenzhen University in China reviewed 19 studies on fried food consumption. They found that there is a linear increase - the more fried food is eaten each week, the higher the risks of heart disease, major cardiovascular events, and heart failure.

The risk for a major cardiovascular event or heart disease increases by 2 to 3% with each additional serving (one serving = 114 g or 4 oz) of fried food per week. Which bring us to the bottom line: Eat fried food sparingly!

From Science Daily: Fried food intake linked to heightened serious heart disease and stroke risk

Fried-food intake is linked to a heightened risk of major heart disease and stroke, finds a pooled analysis of the available research data, published online in the journal Heart. And the risk rises with each additional 114 g (4 oz) weekly serving, the analysis indicates.  ...continue reading "Fried Foods and Risk of Heart Disease"
