“A staggering 60% of all calories Americans consume come from ultra-processed foods that fail to induce proper satiety, remain cheaper than whole foods, and hijack our dopamine reward pathways, pushing us to overeat, incentivizing unhealthy food choices, and reinforcing addictive eating behaviors.”

“Dr. Brooks pairs these relationships with practiced coping methods such as therapy, prayer, meditation, or journaling, creating a practical framework for meeting both everyday stress and major life changes.”

“There is so much to say when we talk about the NRF2 pathway and isothiocyanates like sulforaphane that we had to pack it into 47 minutes and break it into a few key sections. Key sections: For a more in-depth breakdown click the timeline link at the top of this page!”

“Uric acid adds another long-range signal. In the Swedish AMORIS cohort, 1,224 people who reached age 100 tended to have lower midlife glucose, creatinine, and uric acid than peers who did not become centenarians.”

“Older adults can have anabolic resistance and may need more protein per meal to reach a leucine threshold; Dr. Schoenfeld discusses roughly 2–3 grams of leucine as a flexible estimate, not a hard cutoff or a reason everyone needs isolated leucine.”

“Since then, countless studies have tested Pauling's theories about vitamin C, colds, and cancer (and many others), and a substantial body of evidence has emerged, identifying critical roles for vitamin C in immune function, cardiovascular and respiratory health, cognitive development and preservation, and many other aspects of human health.”

“A national survey analysis estimated 2.6% severe deficiency, 22% moderate deficiency, and 40.9% insufficiency among US adults, although prevalence changes with the threshold used. These categories should remain distinct because insufficiency is not the same as clinical deficiency.”

“A standard multivitamin may support selected older adults by filling dietary gaps, and population surveys show that many people consume less than estimated requirements for nutrients such as magnesium, calcium, and vitamins A and C.”

“Lutein and zeaxanthin also have evidence in age-related eye disease, although the AREDS2 trial did not find an additional reduction in progression to advanced macular degeneration in its primary comparison. Magnesium and creatine address different needs.”

“Even if mRNA could enter the nucleus, two other enzymes are missing to transform RNA into DNA and insert it into the human genome. Thus, the series of steps that would result in mRNA incorporating into nuclear DNA is biologically implausible.”
