A study published in the European Journal of Nutrition found that higher estimated dietary exposure to flavoring agents, coloring agents, and sweeteners was dose-dependently associated with a higher risk of incident depression. [^1]

Researchers published findings in the European Journal of Nutrition stating that higher consumption of fruits and vegetables after treatment is associated with a lower risk of recurrence for non-muscle-invasive bladder cancer. [^2]

The study found that every additional 100 grams of fruits and vegetables consumed daily three months after diagnosis was associated with approximately a 9% reduction in the risk of the first recurrence. [^3]

Compared with the modeled intake level associated with the lowest depression risk, having 40% of total food intake represented by foods likely to contain flavoring agents was associated with a 46% higher risk of incident depression. [^4]

Having 20% of total food intake represented by foods likely to contain coloring agents was associated with a 49% higher risk of incident depression compared to the lowest-risk intake level. [^5]

Researchers at Justus-Liebig University of Giessen, Germany, analyzed data from 171,818 UK Biobank participants who completed at least one 24-hour dietary recall questionnaire. [^6]

Patients who increased their fruit and vegetable consumption by 100 grams per day after diagnosis had a risk of recurrence that was approximately 10% lower. [^7]

The authors emphasized that the work was observational and does not prove that fruits and vegetables prevent the return of the tumor. [^8]
