Tiny Mitochondrial Proteins May Explain the Health Benefits of the Mediterranean Diet
A study in Frontiers in Nutrition found that older adults who closely follow the Mediterranean diet have higher circulating levels of the mitochondrial microproteins Humanin and SHMOOSE, both linked to protection against heart disease and cognitive decline. The research compared 49 seniors in Rome with high versus low diet adherence and revealed an inverse relationship between Humanin and the oxidative enzyme Nox2, suggesting reduced oxidative stress. These tiny proteins appear to translate dietary patterns into cellular resilience, offering a potential biomarker for nutritional compliance. The observational design and modest sample size, however, preclude definitive causal conclusions.

Experts Say These 9 Superfoods Can Help You Live a Longer, Healthier Life
A team of registered dietitians identifies nine superfoods—kimchi, turmeric, blueberries, avocado, spinach, kale, lentils, chia seeds, and tempeh—that contain antioxidants, fiber, healthy fats, and micronutrients linked to reduced inflammation and chronic disease risk. The experts explain how each food supports...
Ultra-Processed Foods Linked to Measurable Drops in Human Attention Span
A new cross‑sectional study of over 2,100 Australian adults links higher consumption of ultra‑processed foods (UPFs) to measurable declines in attention span, even among those following otherwise healthy diets. Researchers found that a 10 percent increase in UPF intake—roughly one extra...
How to Know If You Have a Vitamin B12 Deficiency—And What to Do About It
Vitamin B12 (cobalamin) is essential for nerve health, red‑blood‑cell formation and DNA synthesis. Deficiency affects roughly one in ten people over age 75 and presents with fatigue, neurological signs and skin changes. High‑risk groups include seniors, vegans, those with gastrointestinal...
Here’s How to Reduce Your Sugar Intake (Including Six Foods to Avoid)
Dietitians Fareeha Jay and nutritionist Sas Parsad stress that added sugar isn’t needed and should be limited to roughly 33 g (about eight teaspoons) per day. They recommend sourcing natural sugars from fruits, vegetables, dairy, and whole foods while cutting back...
The Best Time to Eat Breakfast? It’s Not Right When You Wake Up
Nutrition experts argue that the optimal breakfast isn’t eaten immediately after waking but delayed until mid‑morning. Waiting extends the overnight fast, supports time‑restricted eating, and encourages the body to burn fat rather than carbs. They recommend rehydrating with salted water...
Nonlinear and Sex-Specific Associations of Maternal Vitamin D in Early- and Mid-Pregnancy with Childhood Growth Trajectories From Birth to 6 Years...
A prospective cohort of 1,100 Chinese mother‑child pairs found nonlinear, sex‑specific associations between maternal vitamin D levels in early and mid‑pregnancy and offspring growth trajectories from birth to age six. Low early‑pregnancy vitamin D increased odds of rising height‑for‑age and BMI‑for‑age Z‑scores,...
The Relationship Between Nutrition Status Indicators and Vitamin D Deficiency in Patients with Type 2 Diabetes Mellitus
A cross‑sectional analysis of 285 hospitalized type 2 diabetes patients in Hebei found that 62% were vitamin D deficient (25‑hydroxyvitamin D < 20 ng/mL). Lower total protein levels were significantly linked to higher odds of deficiency, with an adjusted odds ratio of 0.933 per gram‑per‑liter increase....
Maternal Serum Ferritin Across Gestation and Risk of Small-for-Gestational-Age: A Longitudinal Cohort Study
A longitudinal cohort of 17,451 Chinese pregnancies found that elevated maternal serum ferritin in the third trimester is linked to a higher incidence of small‑for‑gestational‑age (SGA) infants. Women with ferritin ≥18.1 ng/mL at 29‑31 weeks had a 42% greater adjusted odds of...
Socioeconomic Stratification in the Association Between Tea Consumption and Skeletal Muscle Mass Among Oilfield Workers
A cross‑sectional study of 2,574 Chinese oilfield workers found that habitual tea consumption is linked to higher appendicular skeletal muscle mass (ASM). In fully adjusted models, low‑level tea intake raised the skeletal muscle index by 0.105 units and high‑level intake...
Vitamin D Status and Site-Specific Fracture Pattern Associations in Older Adults with Fragility Fractures: A Cross-Sectional Analysis of 2543 Patients
Researchers analyzed 2,543 patients aged 60 and older hospitalized for fragility fractures in China. They found that 35.9% were vitamin D deficient and 44.2% insufficient, with deficiency linked to older age, female sex, winter admission, and prior cerebral infarction. Serum 25(OH)D...

Is Orange Juice Actually Good for You? Here’s What Dietitians Want You to Know
Orange juice delivers a dense micronutrient package—vitamin C, potassium, magnesium, folate and flavonoids—often meeting or exceeding 100% of the daily vitamin C recommendation in an 8‑ounce serving. Store‑bought varieties are pasteurized, shelf‑stable and may be fortified with calcium and vitamin D, but many...
Research Finds This Sustainable Food Source May Help Prevent Diabetes
A recent Clinical Nutrition study examined 152 pre‑diabetic adults who added 200 grams of sardines per week to their diet. Over 12 months, the sardine group’s high‑risk rate fell from 37% to 8%, while a control group saw only a slight...
This Anti-Inflammatory Spice May Be The Key To Better Brain Health
A new research review highlights turmeric’s curcumin as a potent anti‑inflammatory agent that may protect brain health. Clinical data suggest ½–1 teaspoon of culinary turmeric or 500‑1000 mg of standardized extract can improve inflammatory markers and support neurogenesis. Bioavailability remains the...
Research Shows This Underconsumed Fat Improves Inflammation
A recent review in *Nutrients* confirms that increasing omega‑3 fatty acids can markedly reduce systemic inflammation, a condition affecting roughly 34.6% of Americans. Meta‑analyses across 45 studies show improvements in insulin sensitivity, cholesterol, triglycerides and HbA1c, while higher‑dose EPA/DHA (over...
