…according to an article at Annals of Internal Medicine. The study was done in a U.K. population over decade of observation. The 10% or greater reduction in all-cause mortality was seen at a habitual consumption level of two or more cups of black tea daily. Most prior similar studies I’ve seen focus on green tea.

Myopia, aka nearsightedness, is extremely common and can start in childhood or young adults. Over time it can lead to early-onset cataract, retinal detachment, and glaucoma. MedPageToday has an eye-opening article on treatments that can prevent myopia progression and complications. For example:
Common evidence-based treatments that offer both statistically significant and clinically meaningful efficacies include daytime multifocal soft contact lenses (MFSCL), overnight orthokeratology (ortho-k), and topical low dose atropine (LDA). Novel spectacle lenses also showed a promising myopia-inhibiting effect, albeit with limited availability in U.S. at the current moment. On average, these options slow myopia progression by 30-70% compared to conventional single vision glasses or contacts. With properly selected early interventions, not only the development of myopia stabilizes at younger ages, the endpoint of the progression is also much lower, resulting in significantly lower risk of complications. Furthermore, with lower level of myopia at stabilization, many myopic patients could be good candidates for refractive surgery with given corneal thickness.
I get the impression from the article than treatments need to be started in childhood.

No, according to these three credentialed experts at The Conversation. A snippet:
There is a common belief that “good” posture is important to protect the spine from damage, as well as prevent and treat back pain. Good posture is commonly defined as sitting “upright”, standing “tall and aligned”, and lifting with a squat technique and “straight back”.
Conversely, “slump” sitting, “slouch” standing and lifting with a “round back” or stooped posture are frequently warned against. This view is widely held by people with and without back pain, as well as clinicians in both occupational health and primary care settings
Surprisingly, there is a lack of evidence for a strong relationship between “good” posture and back pain. Perceptions of “good” posture originate from a combination of social desirability and unfounded presumptions.

From ScienceDaily:
Starting twice daily flushing of the mucus-lined nasal cavity with a mild saline solution soon after testing positive for COVID-19 can significantly reduce hospitalization and death, investigators report.
They say the technique that can be used at home by mixing a half teaspoon each of salt and baking soda in a cup of boiled or distilled water then putting it into a sinus rinse bottle is a safe, effective and inexpensive way to reduce the risk of severe illness and death from coronavirus infection that could have a vital public health impact.
The irrigation, aka lavage, was not done by simply filling a spray bottle with the saline solution and squirting it up your nose. Participants used one of two high pressure devices: NAVAGE or Neilmed Sinus Rinse. The manufacturer’s of those devices provided at least partial funding for the study.

From the European Journal of Preventive Cardiology:
Decaffeinated, ground, and instant coffee, particularly at 2–3 cups/day, were associated with significant reductions in incident cardiovascular disease and mortality.
“Cardiovascular disease” includes coronary artery disease (e.g., heart attacks), heart failure, and ischemic strokes.
The study was done by Australian researchers using a UK database.

I’m at my one year anniversary of getting Pfizer’s COVID-19 vax. I’m starting to worry less about adverse effects, not that I ever lost much sleep over it. Fortunately, I’m hearing no chatter at my hospital about requiring the boosters. Yet I don’t hear any of the vax mandators saying “we were wrong.” A relative of mine is searching for a job now and reports that the great majority of posted jobs still require the vax. Unbelievable!
Many people assumed the vaccine kills you quickly (in the first two weeks) because that’s when people notice the association and report it to VAERS [Vaccine Adverse Event Reporting System in the U.S.]. This is still true; it does kill some people quickly: half of the deaths reported in VAERS are in the first few weeks.
But the key words are “reported in VAERS.” It turns out that if we don’t have that restriction but are just wondering when most of the deaths after COVID vaccination happen, the answer is different.
Thanks to a helper [whistleblower] who works at HHS [Health and Human Services in the U.S.], we can now clearly see that most of the deaths from the vaccine are happening an average of 5 months from the last dose. That is for the second dose; it may be getting shorter the more shots you get but there are arguments both ways (since there can be survivor bias). Using data from the UK, we can see more clearly that the delay time is around 23 weeks (so a bit more than 5 weeks). We’ll dive into that shortly.
This delay explains why the life insurance companies got off-the-charts all-cause mortality peaks for people under 60 in Q3 and Q4 [3rd and 4th quarters of 2021] rather than right after the shots rolled out.
The five month delay is also consistent with death reports where people are developing new aggressive cancers that are killing them over a 4 to 6 month period.
The 5 month death delay was also confirmed using only European data. That analysis was posted Aug 11, but I learned about it after I wrote this post.
So when you hear of a death from stroke, cardiac arrest, heart attack, cancer, and suicide that is happening around 5 months after vaccination, it could very well be a vaccine-related death.
Kirsch concludes that:
The UK data shows statistical proof of causality of deaths (p<.001): the vaccine doses track with the excess deaths 23 weeks later. Dose dependency is key to showing causality. If no one can explain this, the precautionary principle of medicine requires any ethical society to halt the vaccines now.
In what is possibly related news, guess what’s the top killer in Alberta, Canada, at this time. “Ill-defined and unknown causes.” I’d expect that out of an undeveloped, third-world country, but not Canada. Are they trying to hide something?

Frontiers In Nutrition in July, 2022, published “Fad Diets: Facts and Fiction.” Thank you, FIN, for making it available at no cost. The authors are based in Pakistan and Romania. They attempted to summarize the literature on popular fad diets. I am shocked that they included the Mediterranean diet. Read the article and 134 references then form your own opinion. Some snippets:
Regarding the Atkins Diet: “AD provides several benefits including weight reduction and cardio-metabolic health improvement, but limited evidence exists as compliance is the major barrier to this dietary regimen. Strict supervision by health professionals is advised as adverse metabolic sequelae can result from this type of diet.”
The Paleolithic Diet: “More randomized trials need to be done to highlight the consequences of such diets that eliminate one or more food groups. PD is powerful at advancing weight reduction for the time being but its efficacy in cardiovascular events is not well established as limited long-term data is available.”
Mediterranean Diet: “No evidence of adverse effects associated with MD is available in the literature. Rather, MD has preventive and therapeutic potential for many chronic diseases. It is highly suitable for the general public for the prevention of micronutrient deficiencies and specifically for those patients who are more health-conscious than just weight loss oriented.”
Vegetarian Diet: “No evidence of adverse effects associated with MD is available in the literature. Rather, MD has preventive and therapeutic potential for many chronic diseases. It is highly suitable for the general public for the prevention of micronutrient deficiencies and specifically for those patients who are more health-conscious than just weight loss oriented.”
Intermittent Fasting: “Despite the effectiveness of IF in weight loss as indicated by several studies, the current evidence is non-conclusive. The prime focus of available literature is weight loss but little is known about its sustainability and long-term health effects. More long-term trials should be conducted to draw a clear conclusion.”
Detox Diets: “Energy-restricted DDs are capable of short-term weight loss. But still, there is a high likelihood of health risks from detox products because of their nutritional inadequacy. As no convincing evidence exists in this domain so such diets and products need to be discouraged by health professionals and must be subjected to regulatory review and monitoring.”
Ketogenic Diet: difficult to summarize.

An article earlier this year in the European Journal of Nutrition reported that high consumption of ultra-processed foods is linked to worse-than-average performance on one particular test of cognitive function in older U.S. adults (60+ years-old) who did not have chronic diseases such as diabetes or cardiovascular disease. The particular test was “Animal Fluency.” Never heard of it? Me either. Keep reading.
The study included 2,700 participants, average age 69. Participants were asked to recall what they ate in the prior 24 hours. Foods were “classified according to NOVA, a food classification based on the extent and purpose of industrial food processing, into four mutually exclusive groups: (1) unprocessed or minimally processed foods, (2) processed culinary ingredients, (3) processed foods, and (4) UPFs [ultra-processed foods].”
Ultra-processed foods? “…most foods described as “Frozen meals” or “Lunchables”, as well as some items described as consumed in “Restaurant fast food/pizza” or acquired at a “Vending machine” were classified as UPFs.” Furthermore, the authors write in the introduction that “UPFs, according to NOVA classification system, are industrial formulations of processed food substances (oils, fats, sugars, starch, and protein isolates) that contain little or no whole food and typically include flavourings, colourings, emulsifiers, and other cosmetic additives. UPFs are becoming dominant in diets globally and are replacing traditional diets based on unprocessed and minimally processed foods.
Of the entire study population at hand, UPFs were about half of all calories consumed but ranged from 30 to 70%.
“Cognitive performance was assessed using the Consortium to Establish a Registry for Alzheimer’s Disease (CERAD), Word Learning test, Animal Fluency test, and the Digit Symbol Substitution test (DSST).”
The Animal Fluency test “evaluates categorical verbal fluency (executive function).” “For the Animal Fluency test, the participant is requested to name as many animals as possible within a 60-s [60 seconds, I assume] time period. Each animal corresponds to 1 point and the result is presented as the total sum of points.”
The test subjects were given two other tests of cognitive function but the investigators found no differences in performance based on ultra-processed food consumption. Here are these other two tests:
The two parts of the CERAD Word Learning test consist of (1) three consecutive learning trials, where the participant is requested to recall a list of ten unrelated words immediately after their presentation. Each word corresponds to one point, and the result is presented as a total score across the three trials (range 0–30); and (2) a delayed word recall test, performed after the two other cognitive tests. The result ranges from 0 to 10. … For the DSST, the participant is presented a single sheet of paper where they are asked to match a list of nine symbols to numbers according to a key located on the top of the page. The task had 133 numbers and the participant had 2 min to complete it. The result is shown as the total number of correct matches. For all the tests, higher scores represent better cognitive function.
The authors conclude: “Consumption of UPF was associated with worse performance in Animal Fluency, a cognitive test that assesses language and executive function in older adults without pre-existing diseases such as CVD [cardiovascular disease] and diabetes, while no associations were observed for those with these conditions. While longitudinal studies are required to provide stronger evidence, these results suggest that decreasing UPF consumption may be a way to mitigate age-associated cognitive decline and reduce the risk of dementia.”
I agree these results aren’t very strong.

Comments Off on Ultra-Processed Foods May Impair Cognition in Elderly

An article in the Journal of the Academy of Nutrition and Dietetics found an association between overweight/obesity and consumption of ultra–processed foods in U.S. adolescents.
The study looked at 3,600 adolescents who reported their food intake over a 24-hour period. The results are pretty strong: the more ultra-processed food consumed, the greater the odds of overweight and obesity.
Jan at The Low Carb Diabetic blog reported that:
Ultra-processed foods make up ‘two-thirds of calories consumed by children and teens’
Experts from Tufts University in Massachusetts studied two decades of dietary data to 2018 and found that the amount of calories young people consumed from ultra-processed foods jumped from 61 per cent to 67 per cent.
I’m not paying for the JAND scientific report so I don’t know how they defined ultra-processed foods. The definition varies quite a bit over time, by researcher, and by research goals. From the U.S. National Library of Medicine:
The definitions [of ultra-processed foods] used in 2009, 2010, 2012, 2014, and 2016a represent the definitions used from publications devoted solely to that purpose and are heavily referenced in the literature on ultra-processed foods. The definitions used in years 2015, 2016b, and 2017 are from articles that focused on the relation between ultra-processed food intake and public health nutrition, in which definitions of ultra-processed foods are presented in detail in the article. The first definition alludes mainly to the use of both food additives and salt in food products (6). The second introduces the putative impact of ultra-processed foods on accessibility, convenience, and palatability of ultra-processed foods (8). Subsequently, the definitions become longer and include more elements. Thus, the third definition builds on previous definitions but introduces 2 new angles (9). One is the nonavailability of ingredients used in ultra-processed foods from retail outlets such as supermarkets, and the second introduces food additives as the most widely used ingredients, in numerical terms, in the manufacture of ultra-processed foods. The next definition now introduces the role of food fortification as a defining element of ultra-processed foods (4). Further definitions introduce new elements such as the importance of foods synthesized in a laboratory, based on organic materials such as oil- and coal-based additives and flavoring compounds (10), a specification for the minimal number of ingredients to be found in these foods (5), and then an emphasis on the inclusion of salt, sugars, oils, and fats as a starting point for defining ultra-processed foods. This definition gives details of specific categories of food additives and highlights how the intended use of these additives is to imitate sensory qualities of fresh or minimally processed foods (group 1) or to specifically disguise undesirable qualities of ultra-processed foods (11). The final definition from 2017 (12) is quite similar to that used in the 2016b publication (11).
If you want to dive deep, you can download a list of ultra-processed food examples from that NLM article. I didn’t. But I figure the way to avoid over-processed foods is to eat food closer to the way God made it rather than man-made.

I’ve long been an advocate for price transparency in healthcare. The Centers for Medicare and Medicaid Services (aka CMS) has recently taken action that requires hospitals to post their prices online, which should boost competition and help you shop around to save money. If memory serves, the price posting only applies to a limited number of services. I presume the rare hospitals that don’t accept Medicare and Medicaid payments are exempt.
This week [June 2022], CMS handed down their first penalties to two hospitals in Georgia for failing to comply with the price transparency law that went into effect Jan. 1, 2021.
Northside Hospital Atlanta in Sandy Springs and Northside Hospital Cherokee in Canton were both fined for a lack of readily available standard charges for hospital services online, despite warnings.
The fines were on the order of $200,000 and $900,000.
If you find a hospital breaking the law, report ’em to CMS!
