But Marks points out that the FDA typically follows the advice of its independent advisory committees — and the one that evaluated MDMA in June overwhelmingly voted against approving the drug, citing problems with clinical trial design that the advisers felt made it difficult to determine the drug’s safety and efficacy. One concern was about the difficulty of conducting a true placebo-controlled study with a hallucinogen: around 90% of the participants in Lykos’s trials guessed correctly whether they had received the drug or a placebo, and the expectation that MDMA should have an effect might have coloured their perception of whether it treated their symptoms.

Another concern was about Lykos’s strategy of administering the drug alongside psychotherapy. Rick Doblin, founder of the Multidisciplinary Association for Psychedelic Studies (MAPS), the non-profit organization that created Lykos, has said that he thinks the drug’s effects are inseparable from guided therapy. MDMA is thought to help people with PTSD be more receptive and open to revisiting traumatic events with a therapist. But because the FDA doesn’t regulate psychotherapy, the agency and advisory panel struggled to evaluate this claim. “It was an attempt to fit a square peg into a round hole,” Marks says.

But for the general public, the implications of the study are simpler. “A microwave is not a pure, pristine place,” Porcar says. It’s also not a pathogenic reservoir to be feared, he says. But he does recommend cleaning your kitchen microwave often — just as often as you would scrub your kitchen surfaces to eliminate potential bacteria.

From the article:

As predicted, studies with younger cohorts and separating former and occasional drinkers from abstainers estimated similar mortality risk for low-volume drinkers (RR = 0.98, 95% CI [0.87, 1.11]) as abstainers. Studies not meeting these quality criteria estimated significantly lower risk for low-volume drinkers (RR = 0.84, [0.79, 0.89]). In exploratory analyses, studies controlling for smoking and/or socioeconomic status had significantly reduced mortality risks for low-volume drinkers. However, mean RR estimates for low-volume drinkers in nonsmoking cohorts were above 1.0 (RR = 1.16, [0.91, 1.41]).

Studies with life-time selection biases may create misleading positive health associations. These biases pervade the field of alcohol epidemiology and can confuse communications about health risks. Future research should investigate whether smoking status mediates, moderates, or confounds alcohol-mortality risk relationships.

Forskerne bag det nye studie har sammenholdt resultaterne fra tre enorme amerikanske sundhedsundersøgelser. Undersøgelserne strækker sig over 20 år og inkluderer næsten 400.000 sunde amerikanere, der ikke havde alvorlige kroniske sygdomme.

I løbet af de 20 år døde cirka 165.000 af deltagerne. Studiet viser, at de, der tog multivitamin, ikke levede længere end dem, der ikke gjorde.

Men generelt anbefaler hun, at kosttilskud i form af mineraler og vitaminpiller tages i samråd med lægen.

»Man skal ikke bare tage kosttilskud, man skal gøre det, fordi man har behov for det.«
