| Walnut Cognition Meta-Analysis | This review synthesizes current evidence on the effects of both plant- and animal-derived foods on cognitive outcomes from early development through older adulthood. | 4 | Hardaway C (2026) | Brain Foods: A Narrative Review of Food Items and Their Impact on Cognition over the Life Course. |
| Walnut Cognition Meta-Analysis | Evidence was evaluated across life stages, considering nutrient bioavailability, dietary patterns, and the interplay between structural, socioeconomic, and environmental factors that influence access to these foods. | 4 | Hardaway C (2026) | Brain Foods: A Narrative Review of Food Items and Their Impact on Cognition over the Life Course. |
| Walnut Cognition Meta-Analysis | In early childhood, eggs, meat, and nuts were linked to improved neurodevelopment and reductions in developmental delays, while evidence for seafood and dairy was more mixed. | 4 | Hardaway C (2026) | Brain Foods: A Narrative Review of Food Items and Their Impact on Cognition over the Life Course. |
| Walnut Cognition Meta-Analysis | Background/Objectives : Cognitive function is fundamental to daily life, and nutrition is a key modifiable determinant of brain health across the lifespan. | 4 | Hardaway C (2026) | Brain Foods: A Narrative Review of Food Items and Their Impact on Cognition over the Life Course. |
| Walnut Cognition Meta-Analysis | Among participants with three brain and VAT MRI scans, lower long-term VAT was associated with a slower rate of brain atrophy. | 4 | Pachter D (2026) | Sustained visceral fat loss is associated with attenuated brain atrophy and improved cognitive function in late midlife. |
| Walnut Cognition Meta-Analysis | Improved glycemic control parameters, rather than lipid or inflammatory markers, were mostly related to the favorable longitudinal brain outcomes. | 4 | Pachter D (2026) | Sustained visceral fat loss is associated with attenuated brain atrophy and improved cognitive function in late midlife. |
| Walnut Cognition Meta-Analysis | This long-term, large-scale intervention and follow-up MRI study suggests that sustained visceral fat loss, rather than weight loss, is linked to better cognition and attenuation of brain atrophy years later, mainly via improved glycemic control. | 4 | Pachter D (2026) | Sustained visceral fat loss is associated with attenuated brain atrophy and improved cognitive function in late midlife. |
| Walnut Cognition Meta-Analysis | We examined whether long-term exposure to visceral-adipose-tissue (VAT) influences brain atrophy and cognitive performance years after lifestyle intervention. | 4 | Pachter D (2026) | Sustained visceral fat loss is associated with attenuated brain atrophy and improved cognitive function in late midlife. |
