Typical Human Sleep Hypnogram: Progression of Sleep Stages Across Five Cycles (Light Sleep, Deep Sleep, and Increasing REM) What Insomnia Is Insomnia is a common sleep disorder marked by ongoing difficulty sleeping despite having enough time and opportunity. Symptoms fall into two groups: nighttime sleep problems and daytime consequences. Nighttime Symptoms Trouble falling asleep (taking >20–30 minutes). Trouble staying asleep with frequent awakenings. Waking too early and unable to return to sleep. Sleep that feels unrefreshing or poor‑quality. For a formal diagnosis, symptoms occur ≥3 nights/week for ≥3 months and cause distress or impairment. Daytime Symptoms Fatigue, low energy, or sleepiness. Difficulty concentrating, memory lapses, slower thinking, or more mistakes. Irritability, anxiety, low mood, or frustration about sleep. Reduced motivation, productivity, or performance; higher accident risk. Physical discomforts like headaches, tension, stomach issues, or feeling unwell. ...

Disclaimer: This article has been revised to incorporate recent scientific developments, including ongoing controversies and practical, inclusive consumer strategies. Pesticide risks are dose-dependent, and eating fruits/vegetables remains essential for health. Pesticides are substances designed to control pests, with nearly 11,000 products approved by the EPA for use in everything from agriculture to personal care. [1-4]  While these chemicals protect crops by poisoning target organisms, [25]   their widespread use has significantly impacted biodiversity, often stripping ecosystems of beneficial wildlife. “ Recent reporting warns that our pest ‑ control success has come at a steep ecological cost: in some Iowa cornfields, only cornstalks remain —no bees, no insects, nothing else. [5-7,40]  Other analyses show that widely used pesticides are driving steep declines in U.S. bird populations, accelerating a biodiversity loss that has been unfolding for more than fifty years...

One of the immune disorders is  celiac disease  ( CeD ). CeD is not an allergy , but a chronic autoimmune disease in which the immune system abnormally attacks the lining of the small intestine in response to gluten — a protein found in wheat, barley, and rye — in genetically susceptible individuals. This leads to inflammation and damage, impairing nutrient absorption. Untreated or active CeD can cause serious health problems, including stunted growth in children, osteoporosis, infertility, miscarriage, anemia, neurological issues, and increased risk of other autoimmune conditions or intestinal cancers. CeD affects approximately 1% of the global population (with seroprevalence around 1.4% based on blood tests and biopsy-confirmed rates around 0.7%, varying by region, sex, and age — higher in females and children). However, many cases remain undiagnosed, potentially underestimating the true burden. A landmark 2009 study by Rubio ‑ Tapia et al. (published in Gastroenterology) ...

Updated January 2026 with the latest research from 2024 –2025 studies Shingrix: A New Era in Shingles Prevention and Systemic Health The landscape of adult immunization shifted dramatically in 2017 with the introduction of a powerhouse vaccine that redefined expectations for efficacy. Beyond simply preventing painful skin eruptions, recent clinical insights suggest Shingrix® may offer broader protective benefits for both neurological and cardiovascular health: A Leap in Efficacy : Licensed by the FDA in October 2017 for adults 50 and older, Shingrix® boasts an impressive efficacy rate exceeding 90%, vastly outperforming its predecessor. [4] The Gold Standard Protocol : To ensure maximum immunity, the CDC advises a two-dose series, with the second shot administered two to six months after the first. Official Preference : In late 2017, the ACIP officially designated Shingrix® as the preferred vaccine, even for those who had already been immunized with the older version. Phasing Out the ...

Figure 1.  Fighting 10 hallmarks of cancer with diet 10 Hallmarks of Cancer 1.  Sustaining proliferative signaling Cancer cells generate their own growth signals—or respond continuously to external ones—resulting in uncontrolled cell division. In contrast, normal cells depend on specific growth factors and tightly regulate when they proliferate. 2.  Evading growth suppressors Cancer cells ignore or disable the signals that normally halt cell growth and division, often through mutations in tumor‑suppressor genes such as TP53 or RB. This effectively removes the brakes on proliferation. 3.  Resisting cell death Cancer cells avoid programmed cell death (apoptosis) and other death pathways by upregulating anti‑apoptotic proteins like BCL‑2 or blocking death‑receptor signaling. Normal cells undergo apoptosis when damaged or no longer needed. 4.  Enabling replicative immortality Cancer cells achieve unlimited replicative potential by activating telomerase or alternativ...

What DIAAS Measures The Digestible Indispensable Amino Acid Score (DIAAS) is the gold‑standard method recommended by the Food and Agriculture Organization (FAO) since 2013 for assessing the quality of dietary protein in foods intended for human consumption. It evaluates how effectively a protein source supplies indispensable (essential) amino acids after accounting for how well those amino acids are digested and absorbed in the small intestine. This makes DIAAS a more accurate reflection of true, bioavailable protein quality. Why DIAAS Matters Provides a more precise measure of bioavailable amino acids, including the impact of plant anti‑nutritional factors such as phytates that reduce absorption. Distinguishes high‑quality proteins more clearly (e.g., whey ≈ 109 vs. soy isolate ≈ 90). Avoids score truncation, allowing superior proteins—often animal-based or purified plant isolates—to be fully recognized. Helps optimize mixed diets by identifying limiting amino acids (e.g., lysine in ...
