ABSTRACT
ABSTRACT Objective This research was conducted as a prospective, self-controlled, eight-week clinical trial to investigate the effect of kefir consumption on the lipid profile of individuals with normal and dyslipidemic properties. Methods Kefir microorganisms given to volunteer subjects were determined using classical microbial count methods and qReal-Time Polymerase Chain Reaction. The study was carried out with 23 volunteer hospital health personnel between the ages of 20 and 55 who met the research criteria and did not have any health problems. The volunteers regularly consumed kefir on an empty stomach for four weeks. In the last stage, the eight-week study was completed by making blood and anthropometric measurements of the subjects, who continued to be studied without kefir consumption for four more weeks. Results Considering the changes in the serum lipid profiles of 13 individuals with dyslipidemic symptoms during the 4-week period they consumed kefir, Total Cholesterol values decreased by 9.15% compared to initial values, LDL-Cholesterol values decreased by 10.64%, HDL-Cholesterol values decreased by 6.9%, and triglyceride values decreased by 2.46%. The changes in the serum lipid profiles of 13 individuals with dyslipidemic findings at the end of an eight-week study were a 5.71% decrease in total cholesterol values (p<0.018) considered statistically significant, as well as a 5.31% decrease in LDL-Cholesterol values (p<0.021); the HDL-Cholesterol results were found to be significant with an 8.58% decrease in the values (p<0.035) and insignificant with a 17.21% increase in the triglyceride values (p<0.926). We concluded that regular kefir consumption was effective in both women and men in lowering total cholesterol and LDL-Cholesterol from blood lipid profiles, especially in individuals with dyslipidemic symptoms, while this effect was not observed in normal individuals. Conclusion Kefir can positively affect the total cholesterol and LDL-Cholesterol blood parameters of dyslipidemic individuals with high serum lipid values.
RESUMO
RESUMO Objetivo Esta pesquisa foi conduzida como um ensaio clínico prospectivo e autocontrolado de oito semanas para investigar o efeito do consumo de kefir no perfil lipídico de indivíduos com propriedades normais e dislipidêmicas. Métodos Microrganismos kefir dados a voluntários foram determinados usando métodos clássicos de contagem microbiana e de reação em cadeia da polimerase em tempo real. O estudo foi conduzido em 23 profissionais de saúde de hospitais voluntários, com idades entre 20 e 55 anos, que atendiam aos critérios da pesquisa e não apresentavam problemas de saúde. Os voluntários consumiram kefir com o estômago vazio regularmente durante quatro semanas. No último estágio, o estudo de oito semanas foi concluído com medidas de sangue e antropométricas dos indivíduos, que continuaram a ser avaliados sem consumo de kefir por mais quatro semanas. Resultados Considerando as mudanças nos perfis lipídicos séricos de 13 indivíduos com sintomas dislipidêmicos durante o período de quatro semanas em que consumiram kefir, os valores de colesterol total diminuíram em 9,15% em comparação com os valores iniciais; os valores de LDL-Colesterol diminuíram em 10,64%, os valores de HDL-Colesterol diminuíram em 6,9% e os valores de triglicerídeos diminuíram em 2,46%. Ao final de um estudo de oito semanas, o resultado foi considerado estatisticamente significativo, com queda de 5,71% nos valores de colesterol total (p<0,018); de 5,31% nos valores de Colesterol-LDL (p<0,021) e de 8,58% nos valores de HDL-Colesterol (p <0,035), e insignificantes com aumento de 17,21% nos valores de triglicerídeos (p<0,926). Como resultado do estudo, concluiu-se que o consumo regular de kefir foi eficaz em mulheres e homens na redução do colesterol total e do LDL-Colesterol dos perfis de lipídios no sangue, especialmente em indivíduos com sintomas dislipidêmicos, enquanto esse efeito não foi observado em indivíduos normais. Conclusão O kefir pode afetar positivamente os parâmetros sanguíneos do colesterol total e do LDL-Colesterol de indivíduos dislipidêmicos com altos valores de lipídios séricos.
