AI Article Synopsis
- A study with 25 healthy young adults used a randomized crossover design to assess mood changes after following high and low tryptophan diets for 4 days each, separated by a 2-week washout period.
- Participants reported significantly higher positive mood scores (p<.01) after the high tryptophan diet, but the difference in negative mood was not significant (p>.05).
- The results also indicated that increased dietary tryptophan was associated with lower depressive symptoms and decreased anxiety (p<.05).
Article Abstract
Using a randomized crossover study design, 25 healthy young adults were examined for differences in anxiety, depression, and mood after consuming a high tryptophan and a low tryptophan diet for 4days each. There was a 2week washout between the diets. A within-subjects analysis of the participants' mood indicated significantly (p<.01) more positive affect scores after consuming a high tryptophan diet as compared to a low tryptophan diet. Negative affect differences between the diets were not statistically significant (p>.05). Also, consuming more dietary tryptophan resulted in (p<.05) less depressive symptoms and decreased anxiety.

Background: It is now widely acknowledged that diet, lifestyle, and environmental exposures largely affect an individual's metabolic state in health and disease, including the brain. Metabolomics has demonstrated its potential to enable exciting discoveries in brain health, facilitated by advances in analytical and informatics techniques. Here, we highlighted the use of MS/MS-based untargeted metabolomics to study the diet and medication exposure of cognitively declined cohorts through the newly developed FoodMASST and DrugMASST tools.

Applications of metabolomics in pharmacology are starting to enable a Systems Pharmacology approach, where the outcome of a treatment is considered to evolve from effects on complex molecular networks, enabling insights into response variations. We bring the power of these approaches to the study of the MIND, a Mediterranean DASH diet for prevention of cognitive decline.

Faba bean (Vicia faba L.) offers a rich nutritional profile with high protein content and abundant vitamins and minerals. Processing of faba beans for freezing requires blanching, yielding liluva (legume processing water), possibly containing leached macronutrients, with potential for upcycling.

Objectives: Cancer-related fatigue (CRF) is highly prevalent in patients with breast cancer, resulting in undesirable outcomes and even reduced survival rates. This cross-sectional study investigated the relationship between dietary quality and CRF in patients with breast cancer, and the potential role of gut microbiota (GM) in this association.
Methods: Dietary intake and CRF were evaluated in 342 patients, with 64 fecal samples collected for 16sRNA sequencing and 106 plasma samples for tryptophan (TRP) metabolite determination.

Unlabelled: Dysfunction in the prefrontal cortex can lead to cognitive inflexibility due to multifactorial causes as included cardiometabolic disorders, stress, inadequate diets, as well as an imbalance of the gut-brain axis microbiota. However, these risk factors have not been evaluated jointly. The purpose of this study was to evaluate the effect of physical stress (MS: Male Stress and FS: Female Stress) and high-fat diet (MD: Male Diet and FD: Female Diet) supplementation on the gut microbiota and cognitive flexibility.
