Young does not equal healthy. We routinely see 30 year olds with strokes, heart attacks, and on dialysis mainly due to high blood pressure and diabetes. We've covered articles previously that most of the adult population has a chronic disease and chronic disease onset is occuring at earlier ages over time. We keep heading in the wrong direction.

The efficacy of Nigella sativa L. oil on serum biomarkers of
inflammation and oxidative stress and quality of life in patients
with knee osteoarthritis: A parallel triple-arm double-blind
randomized controlled trial

DOI:10.1002/fsn3.3708
https://onlinelibrary.wiley.com/doi/full/10.1002/fsn3.3708

As someone who has had chronic pain for most of their life, I am always looking for human studies on alternative agents for pain conditions. Chronic osteoarthritis (OA) can be a debilitating condition, and prescription drug treatments such as opioids and NSAIDs can result in serious side effects. This study sought to look at inflammation, oxidative stress, and quality of life in patients with osteoarthritis in a gold standard double-blind, randomized controlled trial.

What they found was after six weeks of supplementation, oral Nigella sativa (black seed oil) decreased hs-CRP (a marker for inflammation), MDA (a marker of oxidative stress), and increased total antioxidant capacity (TAC). Still, compared to placebo, only the decrease in hs-CRP was significant. Significant improvements were seen in general, physical, and mental health scales related to N. sativa oil compared to the placebo group. The authors concluded that six weeks of supplementation effectively improved inflammatory markers and quality of life in knee OA. The topical version was effective in improving quality of life.

In the oral N. sativa group, two cases of eczema were reported, and one incidence of contact dermatitis was reported in the topical group. These effects were labeled as mild. Adherence was high, 86% in the oral group and 84% in the topical group.

This study adds to the body of evidence that N. sativa appears to be safe and effective in treating musculoskeletal pain. Have you tried black seed oil? Let us know in the comments.

What's up, beautiful people! I am back from a content hiatus. I was working on several new projects, and content had to take a backseat until I figured out how to sustainably create new content while maintaining all of my other responsibilities. I will do my best to provide new videos every Tuesday and Thursday at noon CT. These videos will continue to focus on various aspects of lifestyle medicine.

I also have something in the works that I will announce soon with my family. Well actually, two things, but you didn't hear that from me. Have a blessed day y'all!

Associations of Accelerometer-Measured Physical Activity and
Sedentary Time With All-Cause Mortality by Genetic Predisposition
for Longevity

PMID: 36002033
https://pubmed.ncbi.nlm.nih.gov/36002033/

One of the things we frequently hear as healthcare providers is, "Well, it's in my family, so it's just inevitable that it happened." Could your mindset become a self-fulfilling prophecy, and changes to your thought patterns and subsequent behaviors could have influenced the outcome? I love when I come across studies examining the intersection of our behaviors and genetic predispositions.

Exercise and physical activity has been shown to decrease all-cause mortality risk; however, the association of exercise with longevity genes is unknown. This study sought to examine the associations of exercise with longevity weighted by a genetic risk score (GRS) for longevity. The authors looked at three different SNPs associated with longevity in genetic studies and compared the effects of exercise on those with a high, medium, or low genetic predisposition for longevity. They found a significant reduction in mortality for light and moderate to vigorous physical activity measured by an accelerometer. There was also a significant increase in mortality for those with higher sedentary time. There was no significant association with mortality results for a given class of genetic predisposition for longevity.

These findings further support decreasing sedentary time and increasing physical activity to reduce mortality risk as we age. Genetic associations are highly relevant to our health, but we should not just throw up our hands, say it's in our genes, and not actively try to mitigate familial risks.

Incident type 2 diabetes attributable to suboptimal diet in 184 countries

PMID: 37069363
https://pubmed.ncbi.nlm.nih.gov/37069363/

Globally, rates of diabetes are increasing even among younger populations. Diet is one factor that plays a role in the development of diabetes. This study was a risk assessment model looking at how 11 dietary factors influenced new cases of type 2 diabetes stratified by age, s*x, education, urban vs. rural, and geographical location.

The model estimated that in 2018 14.1 million cases (70.3% of total cases) of diabetes were attributable to suboptimal diet. Of the 11 factors examined, the three with the highest attributable burden of new cases were insufficient intake of whole grains (26.1%), excess refined wheat and rice (24.6%), and excess processed red meat intake (20.3%). Excess intake of 6 harmful factors comprised more of the attributable fraction than five protective factors (60.8% vs. 39.2%). In general, the diet-attributable burden of type 2 diabetes was higher for men, in urban vs. rural settings and higher vs. lower educational attainment. There was also an inverse association noted for age.

This study has limitations; as a modeling study, some assumptions must be made, and it does not prove causation. Also, the study did not account for non-dietary factors associated with type 2 diabetes. However, nutrition is part of the big 5 of lifestyle medicine and should be part of a preventative and treatment strategy for type 2 diabetes.

Dietary magnesium intake is related to larger brain volumes and lower
white matter lesions with notable s*x differences

PMID: 36899275
https://pubmed.ncbi.nlm.nih.gov/36899275/

I frequently talk about brain health because neurodegenerative diseases run in my family, and I am an APOE4 carrier. It's estimated that around 50% of Americans consume a nutritional plan with inadequate magnesium intake.

This study looked at a population from the UK biobank utilizing five 24-hour dietary recalls and MRI brain imaging to correlate magnesium intake with brain size and white matter lesions (indicative of brain injury). They found that as magnesium intake increased, brain size increased, and white matter lesions decreased, but the difference was only statistically significant for women. The reference intake was 350 mg daily, and someone who ate more than 550 mg of magnesium would have a brain one year younger, based on their analysis. The study controlled for several variables, including diabetes, lipids, blood pressure medication, alcohol intake, physical activity, smoking, and BMI.

I supplement with magnesium and regularly consume magnesium-rich foods as part of my brain health strategy.

Association Between Daily Alcohol Intake and Risk of All-Cause Mortality

A Systematic Review and Meta-analyses

PMID: 37000449
https://pubmed.ncbi.nlm.nih.gov/37000449/

Low amounts of alcohol are good for overall health, right? It's a question/statement you hear all the time. Previous research showed a j-shaped association between alcohol consumption, meaning lower risk at low consumption and higher risk at higher consumption. What has become evident in observational studies is that light and moderate drinkers have better health markers on a range of health metrics than abstainers (many of whom may have stopped drinking for health reasons). A previous meta-analysis that followed young adults to old age did not show significant cardioprotective benefits from low daily alcohol use. (PMID: 28499102). This study was an updated meta-analysis looking at all-cause mortality and alcohol consumption.

The study looked at five groups of people across 107 cohort studies: lifetime abstainers, former drinkers now abstaining, occasional drinkers (less than 9.1g/week), low volume drinkers (1.3g to 24g per day), medium volume drinkers (25g to 44g per day) high volume drinkers (44g to 64 g per week) and highest volume drinkers (more than 65g per week). In the fully adjusted model (using lifetime abstainers as the baseline), the authors found a slight nonsignificant increase in mortality for low-volume, occasional, and medium-volume drinkers. There was a 19% and 35% increased mortality risk for the high and highest-volume drinkers, respectively.

In another model, when using occasional drinkers as the reference group, there was no significant difference in mortality with low-volume drinkers; a nonsignificant increase in mortality was seen with abstainers and medium-volume drinkers. Higher and highest volume drinkers saw a 24% and 41% increased mortality risk. This study was done in such a way as to minimize different biases and confounders that have been associated with previous findings related to low-volume alcohol consumption.

Brief structured respiration practices enhance mood and reduce physiological arousal

PMID: 36630953
https://pubmed.ncbi.nlm.nih.gov/36630953/

Stress management is broken down into two parts, perceived stress reduction (how to acutely lower stress in the moment) and stress resilience (how to make your body and mind more resilient to stress). Mindfulness and breathwork are both tools that are used in stress management. The pattern and depth of breathing can also affect heart rate, blood pressure, blood oxygenation, and respiratory rate. This study's authors sought to answer whether voluntary controlled breathing would affect mood and physiology differently than mindfulness meditation, which includes passive breath observation. The breathwork interventions were cyclic sighing, box breathing, and cyclic hyperventilation.

108 patients were randomized to the groups and told to practice the breathwork or mindfulness interventions for 5 minutes daily for one month. Mindfulness and breathwork groups significantly reduced state anxiety and negative affect and increased positive affect. There were no significant differences between the groups in state anxiety and negative affect, but the cyclic sighing group saw a statistically significant increase in positive affect. The greater the adherence to the breathwork protocol, the larger the improvement in positive affect. The breathwork group also saw a significantly higher reduction in respiratory rate compared to the mindfulness group. The participants with the greatest respiratory rate reduction also had the highest increase in positive affect throughout the study. No significant changes were seen in heart rate variability, resting heart rate, or sleep over the study duration.

Currently, I aim to do 20 minutes of mindfulness daily (usually while I use my infrared/pemf mat) and do 5 minutes of breathwork daily.

The global burden of high fasting plasma glucose associated with zinc deficiency: Results of a systematic review and meta-analysis

PMID: 36963036
https://pubmed.ncbi.nlm.nih.gov/36963036/

Zinc is the 2nd most abundant trace metal in the human body, behind iron. About 2 to 4 g of zinc is distributed throughout the human body. It has several essential bodily functions, including protein and glucose metabolism and immune system function. Previous human trials have shown that zinc supplementation can reduce blood glucose, hba1c, and blood lipids (PMID: 32722790). The effect size was greater in those with metabolic dysfunction (diabetes or obesity) than in healthy participants. (PMIDL 23137858).

This study aimed to systematically review studies that examined fasting glucose levels in people with and without zinc deficiencies and then measure the association between elevated fasting glucose and zinc deficiency. Two more aims were to determine the population-attributable risk (PAR) and the Disability-Adjusted Life Years (DALY) from elevated fasting glucose attributable to zinc deficiency. For reference, one DALY represents the loss of one year of full health due to premature mortality or years lived with a disability. Zinc deficiency was defined as a serum or plasma level less than 70 ug/dL, and high fasting glucose was defined as greater than 126 mg/dL.

Zinc deficiency was associated with a 134% increased risk of elevated fasting glucose. The PAR of high fasting glucose to zinc deficiency was 6.7% (12.45% in the USA). The DALYs in the USA were slightly greater than 1 million. Zinc is often included in high-quality multivitamins in clinically relevant amounts (10 to 30 mg). I supplement with 25 mg of zinc daily via my multivitamin.

Effects of Time-Restricted Eating on Nonalcoholic Fatty Liver Disease The TREATY-FLD Randomized Clinical Trial

PMID: 36930148
https://pubmed.ncbi.nlm.nih.gov/36930148

Nonalcoholic fatty liver disease (NAFLD) is a growing public health problem affecting 20 to 30% of adults. More than 70% of obese or diabetic individuals have NAFLD. We often see it co-exist with hypertension and hyperlipidemia as well. Early-stage NALFD is usually detected by abnormal liver function tests that prompt an ultrasound. It has no symptoms, but if left untreated, it can progress to severe liver damage and cirrhosis.

This study looked to compare the effects of time-restricted eating (TRE) compared to a daily calorie restriction (DCR) strategy, which aimed to reduce overall calorie intake over 24 hours. The trial was a 12-month intervention that confirmed the presence of NALFD by MRI. A dietary intervention of 1500 to 1800 kcal/d for men and 1200 to 1500 kcal/d for women with a macronutrient profile of 40 to 55% carbohydrates, 15 to 20% protein, and 20 to 30% fat was prescribed for the two groups. The TRE group was instructed to eat between 8 AM and 4 PM. Trained nutritionists provided dietary counseling, participants were encouraged to weigh food for accuracy, and they were required to keep a food log and enter pictures of their food in an app. There were also regular telephone and individual meetings with the nutritionist. The primary outcome of interest was intrahepatic triglyceride (IHTG) content at the end of the study. Secondary outcomes of interest were body weight, BMI, waist circumference, body fat, lean mass, liver enzymes, and several cardiometabolic risk factors.

Vitamin D supplementation and incident dementia: Effects of s*x, APOE, and baseline cognitive status

PMID: 36874594

https://pubmed.ncbi.nlm.nih.gov/36874594/

We are back with what, by now, you know, is one of my favorite things to talk about: vitamin D. Dementia cases are predicted to triple by 2050. Recent evidence points to numerous lifestyle and other modifiable risk factors that can reduce the incidence of dementia (PMID: 35793088). It is estimated that nearly 1 billion people worldwide suffer from vitamin D deficiency. Mechanistically, it is thought that vitamin D may provide neuroprotection from the degenerative changes associated with Alzheimer's disease (AD). Low serum vitamin D levels are associated with an increased risk of dementia and AD.

A new paper examined vitamin D supplementation and the risk of developing dementia. They followed 12,388 patients for ten years without dementia and grouped them into those with vitamin D exposure and those without. Vitamin D exposure was associated with a 40% lower risk of developing dementia and a higher dementia-free survival period after adjustments for age, s*x, education, cognitive status, depression, and APOE4 status. The effects were more substantial in women, those without mild cognitive impairment at baseline, and those without APOE4 carrier status.

As a carrier of an APOE4 allele and watching my grandfather pass from dementia, I am always interested in studies that shed light on lowering the risk of developing dementia. Vitamin D supplementation is cheap, effective at raising blood levels, and has been proven safe in multiple studies (many of which we have discussed before).

Lecanemab in Early Alzheimer's Disease

https://www.nejm.org/doi/full/10.1056/NEJMoa2212948

I saw this trial was making waves across the news as a potential savior for Alzheimer's disease. I am an APOE4 carrier, so I pay close attention to developments in brain health.

This study leaves me with more questions than answers. The population selected as those with mild cognitive impairment or dementia due to Alzheimer's disease by the Clinical Dementia Rating - Sum of Boxes score. The primary endpoint was a change in the CDR-SB over 18 months, and the secondary endpoints included a change in the amyloid burden on PET scans and a few other rating scales.

There was a statistically significant difference in the primary endpoint of -0.45 (1.66 vs. 1.21) in the CDR-SB. So the patients who received the infusion had a slower rate of cognitive decline. There was a significant reduction in amyloid plaque burden in the lecanemab group to a mean level below the threshold for elevated brain amyloid levels. However, according to a recently published study examing the clinical relevance of changes in several different scoring mechanisms, a 0.5 change is the threshold for clinical significance (PMID: 35835560). That study also found a combination of tests that had a high AUC (a measure of predictive accuracy) for predicting composite clinical measures. The tests used in the Lecanemab study (outside of the delayed recall test, which approached clinical significance based on the measures seen in PMID: 35835560) were not the same used in the predictive study.

Also, 26.4% of the intervention participants had infusion-related reactions, which were mainly mild, and 12.6% had brain imaging abnormalities with edema or effusions. However, the deaths were similar in both groups (0.7% lecanemab vs. 0.8% placebo).

My main concerns are two-fold. 1. Are these changes seen in these scoring systems clinically relevant? Over the course of a longer treatment duration, would there be a meaningful difference in outcome measures that patients care about? 2. If they are clinically relevant, are they cost-effective compared to other clinical modalities like exercise?

Association of Ultraprocessed Food Consumption With Risk of Dementia A Prospective Cohort Study

PMID: 35896436
https://pubmed.ncbi.nlm.nih.gov/35896436/

The WHO estimates that nearly 50 million people live with dementia, which is projected to triple by 2050. Dementia is the 6th leading cause of death in the US.

I am a carrier of the APOE4 gene, which confers an increased genetic risk of developing Alzheimer's dementia (AD). I am very intrigued by brain health and how we can increase or decrease our risk of dementia through our behaviors and mindset.

This trial was a prospective cohort study where nearly 72,000 people were followed for a median duration of 10 years. In the fully adjusted model (adjusted for things like s*x, age, education, smoking, drinking, BMI, sleep, total energy intake, APOE4 status, etc.), for every 10% increase in UPF, there was a 25% increased risk of developing dementia, a 14 % increased risk of developing AD, and a 28% increased risk of developing vascular dementia. Replacing 10% of UPF by weight in our nutrition plans with an equivalent amount of unprocessed or minimally processed foods was estimated to lower the risk of dementia by 19%. The portion of a person's total food intake in the US may be as high as 65%.

Research continues to show that our behavior set can modify and ameliorate significant amounts of the risk of developing what many consider one of the most devastating diseases. I watched my grandfather pass from AD. Much of what I do daily is to help lower my risk and protect my brain. The quantity and caliber of your food matter!
