Reactions: study links emulsifier consumption by pregnant mice to health problems in offspring

A study in mice found "mild metabolic and neuropsychological malprogramming" in the offspring of females who, during gestation and lactation, had ingested emulsifiers, substances used to improve the texture of ultra-processed foods. The article, led by a team from IDIBAPS in Barcelona and published in PLoS Biology, states that the consumption during these periods of carboxymethylcellulose and polysorbate 80 - two common emulsifiers - diluted in water was associated with metabolic and cognitive deficits in the mouse offspring.

Reactions: aspartame sweetener is classified as possibly carcinogenic to humans, although the acceptable daily intake remains unchanged

The International Agency for Research on Cancer (IARC) and the Joint FAO/WHO Expert Committee on Food Additives (JECFA) have published a health impact assessment of the sweetener aspartame. Citing "limited evidence" of carcinogenicity in humans, IARC has classified aspartame as possibly carcinogenic to humans (Group 2B). For its part, JECFA has not changed the acceptable daily intake of this sweetener, which is set at 40 mg/kg body weight. According to these bodies, with one can of diet soft drink containing 200-300 mg aspartame, a 70 kg adult would need to consume more than 9-14 cans per day to exceed the acceptable daily intake - assuming no other intake from other dietary sources.

Reaction to the first meta-analysis studying the effect of a Mediterranean diet on women's cardiovascular health and mortality

A review of studies of more than 700,000 women has estimated that those who follow a Mediterranean diet faithfully have about a 25% lower risk of cardiovascular disease and death. This effect is greater than had been found in other studies, many of which included a majority of men and did not differentiate results by sex. According to the authors, the study underscores the need for this type of targeted analysis. The results are published in the journal Heart.
