Using the calibration approach for attenuating the systematic error of self-reported EI, we aimed to compare trends in BMI and EI with and without calibration in adults from the USA and Japan. This cross-sectional study included 38,370 Americans evaluated in the National Health and Nutrition Examination Survey 2003-2018, and 200,629 Japanese evaluated in national nutrition surveys in Japan 1995-2019. EI was estimated using at least 1 day of 24-h diet recalls for Americans and 1 day of household-based dietary records for Japanese. The calibrated EI was calculated using a previously developed equation based on total energy expenditure (TEE) measured by doubly labelled water method. Using data from a review, uncalibrated EI was -20.2% and calibrated EI was -4.1% compared to the TEE; the calibration approach attenuated EI underestimation. In the USA, uncalibrated EI decreased (annual percentage change [APC]: -0.24%), but calibrated EI and BMI increased (calibrated EI, APC: 0.04%; BMI, APC: 0.32%). In Japan, the decrease was smaller for the calibrated EI than for the uncalibrated EI (uncalibrated EI, APC: -0.23%; calibrated EI, APC: -0.04%). Uncalibrated EI decreased and BMI increased in the USA and Japan, and calibrated EI increased in the USA and decreased slowly in Japan.

Lower-income areas exhibited significantly higher hypertension prevalence (EE = 1.233, 95% CI: 1.128-1.347 for incomes under $14,999), neighbourhoods with greater food resource density showed protective associations (EE = 0.549, 95% CI: 0.474-0.636 for supermarket access).

Our proposed 'Food Environment Synergy Model' helps frame these findings by conceptualising food environments through three interacting dimensions: physical access, economic accessibility, and cultural dietary patterns. This integrated approach highlights how these dimensions collectively relate to unique risk and resilience profiles within communities, challenging conventional binary classifications of 'food deserts' versus 'food secure' areas. These findings indicate that addressing food access disparities, promoting walkable neighbourhoods, and preserving beneficial cultural dietary traditions may be related to lower hypertension prevalence and advance health equity in diverse communities.

This study aimed at assessing the association between legume consumption and nutritional status in children aged 6-59 months in rural Malawi. A community-based cross-sectional study was conducted in Mzimba, Mchinji, and Mangochi districts, involving 1275 children. Data were collected on dietary intake, socioeconomic status, and anthropometry using semi-structured questionnaires.

Over half of the children did not consume legumes. Pigeon pea consumption significantly reduced odds of wasting (AOR = 0.14), and common beans were associated with lower odds of both wasting and stunting. Conversely, groundnut consumption was linked to increased underweight (AOR = 1.68). Animal food consumption was associated with lower underweight but higher odds of wasting. Legume consumption showed both protective and adverse associations with child malnutrition.
