Who was studied112,395 NutriNet-Santé cohort participants, average 7.9 years

What changedCardiovascular disease rates were higher in the highest versus lowest food coloring intake third (hazard ratio 1.18)

The catchParticipants’ dietary records can misestimate food coloring intake

Who was studied46,563 Indian adults aged 50 and older

What changedOdds of multiple cardiometabolic conditions were higher with weak grip and obesity than with neither (odds ratio 3.14)

Who was studied1,131 women going through the menopause transition
