Claim 1 of 6Not coveredResearchers analyzed before-and-after health data from 68 adult participants who received an average of 97 plant-based grocery packages over 2.7 years.View evidenceHide evidence

As stated68 adult participants; average of 97 packages

Why this verdict

The abstract-profile supports analysis of 68 adults with baseline-to-follow-up cardiometabolic outcomes over an average 2.7 years. However, the stated average of 97 packages received is not present in the supplied abstract-level profile, so that part cannot be verified at this depth.

Study evidence

Each 100 MTGs received was associated with a greater improvement in the rate of change in diastolic blood pressure from baseline to follow-up.-3.21 mm Hg (95% CI, -4.89 to -1.52) per 100 MTGs

“This study examined the association of weekly plant-based medically tailored groceries (MTGs) with cardiovascular-kidney-metabolic outcomes among patients with food insecurity.”
Claim 2 of 6Not coveredAmong participants with elevated blood pressure at baseline, the program was also associated with reductions in systolic blood pressure.View evidenceHide evidence

Why this verdict

The abstract-profile says systolic blood pressure was an outcome, but it does not report systolic blood pressure effect estimates, subgroup results, or findings among participants with elevated baseline blood pressure. This claim may come from full text, but it is not verifiable from the supplied abstract-level evidence.

Study evidence

Each 100 MTGs received was associated with a greater improvement in the rate of change in diastolic blood pressure from baseline to follow-up.-3.21 mm Hg (95% CI, -4.89 to -1.52) per 100 MTGs

“This study examined the association of weekly plant-based medically tailored groceries (MTGs) with cardiovascular-kidney-metabolic outcomes among patients with food insecurity.”
Claim 3 of 6Not coveredThere were no significant improvements in hemoglobin A1c across participants.View evidenceHide evidence

Why this verdict

The abstract-profile lists HbA1c as an outcome but does not provide an effect estimate, confidence interval, or significance result. Therefore the claim that there were no significant HbA1c improvements cannot be verified at abstract depth.

“This study examined the association of weekly plant-based medically tailored groceries (MTGs) with cardiovascular-kidney-metabolic outcomes among patients with food insecurity.”
Claim 4 of 6SupportedA new study led by Mass General Brigham researchers found that a longer-duration Food Is Medicine program was associated with dose-dependent improvements in cardiometabolic health in adults.View evidenceHide evidence

Why this verdict

The abstract-profile describes an observational longitudinal dose-response analysis in adults and reports that each 100 medically tailored grocery packages was associated with improvements in diastolic blood pressure, weight, and BMI. The story frames this as an association, not causation.

Claim 5 of 6SupportedParticipants who received weekly plant-based grocery packages for an average of 2.7 years showed dose-dependent reductions in diastolic blood pressure, body weight, and body mass index (BMI).View evidenceHide evidence

As statedaverage of 2.7 years

Why this verdict

The profile supports 68 adults followed for an average of 2.7 years and reports dose-dependent associations between MTG receipt and reductions in diastolic blood pressure, weight, and BMI. The wording is somewhat declarative, but it does not clearly assert causation.

“This study examined the association of weekly plant-based medically tailored groceries (MTGs) with cardiovascular-kidney-metabolic outcomes among patients with food insecurity.”
Claim 6 of 6SupportedOn average, every 100 food packages received were associated with a 3.21 mmHg reduction in diastolic blood pressure, a 2.6 kg reduction in weight, and a 1.04 kg/m2 reduction in BMI.View evidenceHide evidence

As stated3.21 mmHg, 2.6 kg, 1.04 kg/m2 per 100 packages

Why this verdict

The reported per-100-package estimates match the abstract-profile: diastolic blood pressure -3.21 mm Hg, weight -2.63 kg, and BMI -1.04 kg/m2 per 100 MTGs. The story’s 2.6 kg value is a reasonable rounding of -2.63 kg.

What the story left out

Important study details the story did not include.

  • Study population: 68 adults with food insecurity receiving medically tailored groceries from a food pantry program.

    The story reflects the sample size and adult population, but the supplied presentation does not mention that participants were food-insecure adults, which is important for generalizability.

    From Observational longitudinal dose–response analysis (linear mixed-effects models)

4 things the story did carry across
  • Central study design: observational longitudinal dose-response analysis of weekly plant-based medically tailored groceries, not a randomized controlled trial.
  • Exposure and follow-up: cumulative weekly MTG receipt over an average 2.7 years, analyzed per 100 packages received.
  • Main abstract-reported findings: each 100 MTGs was associated with improvements in diastolic blood pressure, weight, and BMI.
  • Small sample size: n=68.

Lead result

1Lead resulthuman in vivoAssess whether receipt (dose) of weekly plant-based medically tailored groceries (MTGs) from a food pantry is associated with longitudinal changes in adult cardiometabolic outcomes (blood pressure, HbA1c, weight, BMI) among patients with food insecurity over follow-up.Observational longitudinal dose–response analysis (linear mixed-effects models)Expand

In plain English

Observational longitudinal dose–response analysis of 68 food-insecure adults (mean follow-up 2.7 years) relating cumulative weekly plant-based medically tailored groceries (MTGs; program active Dec 20, 2019–Apr 1, 2025) to rates of change from baseline in cardiometabolic outcomes using linear mixed-effects models. The abstract reports that each 100 MTGs received was associated with greater improvements in diastolic blood pressure, weight, and BMI; effect estimates for systolic blood pressure and HbA1c are not reported in the abstract.

Key findings

  • Each 100 MTGs received was associated with a greater improvement in the rate of change in diastolic blood pressure from baseline to follow-up.-3.21 mm Hg (95% CI, -4.89 to -1.52) per 100 MTGs
  • Each 100 MTGs received was associated with a greater improvement in the rate of change in weight from baseline to follow-up.-2.63 kg (95% CI, -3.73 to -1.53) per 100 MTGs
“This study examined the association of weekly plant-based medically tailored groceries (MTGs) with cardiovascular-kidney-metabolic outcomes among patients with food insecurity.”
What this piece can’t prove
  • Observational association reported; abstract does not describe randomization or a controlled trial design.
