Qualitative Analysis of Acid-Base Nutrition and its Effect on the Human Body

Abstract

Introduction. The influence of diets on the acid-base balance (pH) of a person has not been studied enough in our time. The substances contained in food products, entering the body, are able to exert an acidic or alkaline load, affecting the pH value. The purpose of the study to identify the dependence of the psychoemotional state of a person on the acid load in the diet. Materials and methods. On the Google platform in the autumn season, a survey was conducted of 64 residents of the Sverdlovsk Region aged 18 to 52 years (average age — (23.84±5.2)) for the presence in their diet of products that affect the acid-base balance. The study of the psycho-emotional status of respondents was carried out using a questionnaire that allows you to give a subjective assessment of their well-being, activity and mood (SAN) on a scale from 1 to 7 points. Based on the data obtained, 2 groups were formed: 1 — with a labile mood (≤4.5 points), 2 — with a good mood (>4.5 points). After assessing the Potential Renal Acid Load Index (PRAL), the respondents received recommendations for adjusting their diets to include foods that form a negative and neutral pH value. After 14 days of consumption of the adjusted diets, the SAN questionnaire was repeated. Results. Initially, the average PRAL value of the respondents was (36.95±9.83) m‑Eqv. At the end of the study, the mean PRAL was (1.37±1.20) m‑Eqv. In the group before correction of the diet, WAN was (4.40±0.35) points, after correction it was (4.60±0.47) points (p = 0.016). Conclusions. An increase in the diet of plant products has a positive effect on the psycho-emotional state of a person, which is confirmed by the SAN indicator.
