Globally, added sugar now makes up around 10% of total calories consumed, ranking just behind grains and produce. But while those provide some nourishment, sugar contributes little and harms much.

UCLA researchers uncovered four distinct “roadmaps” leading to Alzheimer’s by analyzing longitudinal health records from nearly 25,000 patients and validating findings in the All of Us cohort. These sequential diagnostic patterns predicted dementia better than any single risk factor.

A 2025 pooled cohort study of 1.56 million UK adults found that those diagnosed with autoimmune or chronic inflammatory conditions had a 86% higher likelihood of experiencing affective disorders (depression, anxiety, bipolar) compared to people without these conditions.

A 2025 study reported in ScienceDaily highlights that a single dose of psilocybin produced significant and sustained reductions in depression for cancer patients—lasting up to 2 years after treatment.

A 2024 systematic review in BMC Public Health found that children with higher screen use were more likely to develop depressive symptoms later, especially between ages 9 to 12—or teens who spend much time on screens showing increased depression, anxiety, inattention, and aggression.

A 2025 feasibility trial by Meinlschmidt et al. studied 54 women with and without obesity after a 10-hour daytime fast.

A 2025 study from Shanghai Jiao Tong University showed that food allergies don’t just cause rashes or stomachaches—they can lead to anxiety, depression, attention issues, and social withdrawal. In this mouse model, food allergy triggered brain inflammation, impaired behavior, and disrupted the gut microbiota.
