Myth: any vitamin D supplement works the same. Research suggests vitamin D2 can actually lower your body's D3 levels, and D3 is the form made by sunlight and better at raising overall levels.
Take: Check the label and choose D3 over D2 when possible; ask a clinician or pharmacist whether you need to supplement and at what dose.
Myth: every trans fat harms the heart. A large review found naturally occurring trans fats in milk, butter, yogurt and cheese show no meaningful link to heart disease or type 2 diabetes; the harmful ones are industrial trans fats from partially hydrogenated oils.
Take: Scan ingredient lists for 'partially hydrogenated oil,' but you don't need to give up milk or yogurt over their natural trans fats.
Myth: prescribing is purely objective. A Cochrane review found payments, gifts and free meals from drug companies heavily influence prescribing, leading to more prescriptions for pricier, less appropriate drugs.
Take: Ask your doctor whether there's an equally effective but cheaper alternative, and have a pharmacist review any new prescription for necessity.
Myth: the order you eat a meal in doesn't matter. Research shows eating vegetables or low-glycemic foods first, then carb-heavy foods, shifts short-term blood sugar and insulin responses after the meal.
Take: Start your meal with a couple bites of vegetables or salad before rice, noodles or potatoes — a zero-cost change you can try today.
Myth: diet doesn't matter during an antibiotic course. Research links eating more sugar while taking antibiotics to greater gut microbiome disruption and more growth of potentially harmful bacteria.
Take: During and shortly after antibiotics, go easy on sugary drinks and desserts to give your gut bacteria room to recover.
Myth: certain 'anti-cancer foods' can prevent or treat breast cancer. Experts interviewed during Breast Cancer Awareness Month say these are common food myths without solid evidence.
Take: Don't rely on a single food or pricey supplement for cancer prevention; balanced eating, weight control and recommended screening are more practical.
Myth: if the scale doesn't move, exercise isn't working. In mice, just seven strength-training sessions shrank visceral fat cells and reactivated fat-burning pathways, even with no change in overall body weight.
Take: Don't watch only the scale; when you start strength training, track waist size, fitness and energy — these may change before weight does.
Myth: NAD-boosting supplements help Parkinson's disease. A yearlong trial of 410 people with early Parkinson's found no clinical benefit from nicotinamide riboside (NR).
Take: Don't self-prescribe NAD-type supplements to 'treat' Parkinson's; talk to a neurologist about evidence-based options.
Myth: endless doomscrolling is just a willpower problem. NPR Life Kit offers practical tips to cut screen time and reconnect with real life.
Take: Try one small step today: charge your phone outside the bedroom, or set a fixed phone-free window — even just 20 minutes.
Myth: calcium in blood vessels seen on a mammogram is just incidental and not worth mentioning. A new Maryland law requires patients be told if mammogram results show calcium deposits in blood vessels, a possible heart disease warning sign.
Take: When you get a mammogram, ask whether the report notes vascular calcification; if it does, don't panic — ask a clinician to assess your overall heart risk.
