Background: Cystic fibrosis (CF) is an autosomal recessive monogenic disease marked by a mutation in the cystic fibrosis transmembrane conductance regulator gene. Cystic fibrosis transmembrane conductance regulator gene mutations affect respiratory, digestive and reproductive functions and impede bicarbonate, bile acid, and sweat secretion. Moreover, the current trend indicates that CF is no longer only a paediatric disease, but has progressively become a disease that also affects adults. This calls for addressing the condition with an appropriate nutraceutical approach.
Objective: The study aims to find and collate nutritional targets in the management of cystic fibrosis.
Methods: Studies highlighting the benefits of nutrients or nutraceuticals in the management of cystic fibrosis were included from previously published research articles (1971 to 2020). Data including nutrients, nutraceuticals, study design, study model, sample size, age, dose and duration of the dose of the supplement were extracted from the studies included and explored to understand their role.
Results: About 26 studies were included in the present review. It was found that nutrient interventions comprising nutraceuticals, including dietary fibre, proteins and amino acids (taurine, arginine, glutathione), fats (medium-chain triglycerides, polyunsaturated fatty acids (omega-3 fatty acids), phytochemicals (apigenin, genistein, quercetin, curcumin, allicin, beta-carotene, Pulmonaria officinalis L, Epigallocatechin-3-gallate), micronutrients, including vitamin A, vitamin D, vitamin K, magnesium and zinc in addition to antioxidants exhibit improvement in the symptomatic condition of cystic fibrosis patients.
Conclusion: The advent of nutraceuticals in the food industry and studies indicating their promising benefits have paved a path for targeted therapies in cystic fibrosis.
