(1) Background: We aimed to associate the degree of food processing with blood pressure levels in adult women. (2) Methods: A cross-sectional study was carried out on 85 adult women. The participants were subdivided into three groups: normal weight (NW: 27.05%), overweight (OW: 34.1%) and obesity (OB: 38.8%). Their anthropometric parameters, food consumption and blood pressure (BP) were evaluated. The groups were compared using one-way ANOVA or the Kruskal–Wallis test, and correlations were established using Spearman’s correlation, partial correlations (adjusted for age, medications and pathologies) and simple linear regression. Significance was set at <i>p</i> < 0.05. (3) Results: Women with obesity had higher systolic and diastolic blood pressure (SBP = NW: 106.5 ± 11.6; OW: 111.60 ± 11.8; OB: 123.63 ± 14.0; <i>p</i> < 0.001 and DBP = NW: 66.5 ± 9.9; OW: 70.2 ± 8.7; OB: 80.6 ± 11.0; <i>p</i> < 0.001) and a lower consumption of unprocessed or minimally processed food (MPF) (NW: 0.25 ± 0.1; OW: 0.27 ± 0.09; OB: 0.21 ± 0.07; <i>p</i> = 0.027). Moreover, we found an inverse association among the consumption of MPF and diastolic blood pressure that remained after adjustments for covariates (r: −0.27; <i>p</i> = 0.01), suggesting that lower consumption of MPF is related to higher levels of DBP. (4) Conclusions: Our data suggest that women with obesity seem to have a lower consumption of MPF. In addition, MPF is negatively correlated with BP, suggesting an association with obesity and cardiovascular health.
