April nutrition notes from Roc Nutrition Investigator

Dear partners in health,

Here are updates for April. We are getting settled in, and I hope to begin work on the essays I promised, while also pursuing my business plans. Yet still I read exciting news to share. Thanks for paying attention.

Why I supplement with niacin daily: Additional investigations targeted to elucidate the cellular pathways responsible for the ability of nicotinamide to modulate both lifespan extension and cytoprotection may offer critical insight for the development of new therapies for nervous system disorders.

A recent article in Science explains a lot about depression, and how there is a legitimate scientific for its cause.  Stress is one of the primary causes of depression, and SAMe is the natural metabolic means children have for managing stress. As we age, it is useful to take as a supplement. Otherwise, stress decreases nerve function in the brain leading to depression.  “Don’t worry, be happy!”

 Laughing less than once a week doubles your risk of dying!

Zinc and copper dosage in AREDs may lower risk of death by 20% during the studies. A meta-analysis of 7 studies indicates those getting a bit of zinc and copper each day maintain their health significantly better than others.

Reader question: How much vitamin K should one consider taking on a daily basis? Vitamin K functions as a coenzyme for vitamin K-dependent carboxylase, an enzyme required for the synthesis of proteins involved in hemostasis (blood clotting) and bone metabolism, and other diverse physiological functions [3,5]. Prothrombin (clotting factor II) is a vitamin K-dependent protein in plasma that is directly involved in blood clotting. Warfarin (Coumadin®) and some anticoagulants used primarily in Europe antagonize the activity of vitamin K and, in turn, prothrombin [8]. For this reason, individuals who are taking these anticoagulants need to maintain consistent vitamin K intakes.

The Adequate intake for men and women is 120 and 90 μg/day, respectively. No adverse effect has been reported for individuals consuming higher amounts of vitamin K, so a Tolerable Upper Intake Level (UL) was not established.

Reader question: Please comment on the Apr. 16th NIH study “no benefit for dietary supplements.”  First, here are many great quotations from the NIH report: “people who took more than 1,000 milligrams of supplemental calcium per day were more likely to die of cancer than those who didn’t… more than half of the study’s participants had inadequate intake of vitamins D, E, and K, as well as choline and potassium… people who took supplemental vitamin D at a dose exceeding 10 micrograms (400 IU) per day without a vitamin D deficiency were more likely to die from cancer… study participants who reported taking dietary supplements generally had a higher level of education and income. They also tended to enjoy a healthier lifestyle. They ate more nutritious food, were less likely to smoke or drink alcohol, and exercised more. So, it appears that people who take dietary supplements are likely to live a longer and healthier life for reasons that are unrelated to their supplement use.”

Roc’s response: This is a survey of everyone taking supplements, not a study of people who take particular supplements. I disagree totally. Random people taking random supplements, e.g. big calcium pills, are worse off. But choosing supplements wisely, as I think I do, has proven rewards in many cases, e.g. AREDs to delay macular degeneration. I am concerned about the vitamin D result, as the top expert on vitamin D has told me every 2 of the past 6 years to take 2,000 IU daily, and I still do.

From Kevin Fickenscher’s newsletter: the addition of 10 primary care physicians for a population cohort of 100,000 resulting in a “51.5 day increase in life expectancy whereas an increase in 10 specialist physicians per 100,000 population corresponded to a 19.2-day increase.”  A large study from the US reports that people who engage in high levels of leisure activity throughout their entire lives had a 1/3 lower in their risk of death.

Autism spectrum disorder (ASD) is a term used to describe a range of conditions that affect communication, social interaction and behaviour. This includes Asperger syndrome. ASD is relatively common, with around 1 in every 100 people affected by the condition to some degree. there are various techniques that can be used to help children and adults with ASD fall asleep more quickly and have better-quality sleep when they do. https://www.sleepreports.com/autism-and-sleep-problems-advice/.

 We investigated the effect of cognitive task difficulty and motor task type (walking versus an upper-extremity function [UEF]) in identifying cognitive impairment in older adults. This study demonstrated that counting backward by threes within a UEF dual-task experiment was a pertinent and challenging enough task to detect cognitive impairment in older adults.  https://www.dovepress.com/article_44979.t100749627
