Association between bacterial growth in the intestinal flora, and blood pressure of hypertensive elderly men after five weeks of consumption of soja (Glicine máx).

Objective: To determine the association between bacterial growth of intestinal flora and arterial pressure of hypertensive elderly men after five weeks of consumption of Soybean (Glycine max). Materials and methods: Quasi-experimental design to evaluate the association between changes in blood pressure and bacterial growth in 24 hypertensive men aged between 61 and 82 years living in Las Malvinas (southwest of Barranquilla), who added to the usual diet "Soy milk study whole" grain lactose (18 g. soy protein per day) for 6 weeks. In the microbiological analysis of stool gender and amount of bacteria were determined by traditional techniques. Blood pressure at the beginning and end of treatment was measured. Results: The counts of aerobic the start bacteria was 10 ⁵ to 10 ⁹, and the end 10⁶ to 10 ⁹ CFU / gram of sample, in anaerobic bacteria are the highest counts found: 10 ⁵ to 10 ⁹ before and 10 ⁶ to 1010 CFU /g at the end. After treatment with soy systolic pressure decreased by 37.5 % of participants, diastolic in 16.67 %, 45.83 % on average and 45.83 % in pulse, but there was no statistical significance in any case. The Pearson correlation coefficient between arterial pressure and bacterial growth was - 0.14. Conclusions: Aweak inverse association between increased intestinal microbiota and decrease in arterial pressure was observed.
