RESUMEN
Reference values for Fatty Acids (FAs) are not well defined in the Indian population. Therefore, it is critical to establish FAs reference range for the healthy non-pregnant and pregnant Indian population. The present multi-centric, and cross-sectional study determines the 95% reference interval for FAs in an apparently pregnant Indian population and compare it to the healthy non-pregnant women. Physicians identified 164 reference individuals as healthy (56 non-pregnant and 108 pregnant) at various government and private hospitals of northern India. The 95th and 97.5th percentile reference limits were used to estimate the 95 percentile of the reference distribution. The reference ranges observed for Alpha-linolenic acid (0.29-0.42%; 0.36-0.58%), Docosahexaenoic-acid (3.38-4.23%; 3.8-4.55%), Eicosapentaenoic-acid (1.24-1.76%; 1.09-1.62%), Docosapentaenoic-acid-3 (0.61-0.69%; 0.65-0.76%), Linoleic-acid (18.44-20.75%; 19.51-21.88%), gamma-linolenic-acid (0.24-0.35%; 0.32-0.42%), Eicosatrienoic-acid (0.26-0.32%; 0.34-0.39%), Arachidonic-acid (9.29-11.02%; 10.02-11.56%), Docosatetraenoic-acid (0.62-0.89%; 0.79-1.09%), Docosapentaenoic-acid-6 (0.23-0.31%; 0.33-0.41%), Eicosatrienoic-acid (1.17-1.41%; 1.43-1.74%), Eicosenoic-acid (0.28-0.38%; 0.37-0.49%), Nervonic-acid (1.39-1.69%; 1.41-1.74%), Palmitoleic-acid (1.17-1.58%; 2-2.66%), Oleic-acid (19.8-22.26%; 19.68-22.94%), Myristic-acid (1.16-1.68%; 0.82-1.3%), Palmitic-acid (20.05-21.8%; 20.7-22.43%), Stearic-acid (11.34-12.56%; 10.29-11.02%), Arachidic-acid (0.17-0.2%; 0.18-0.23%), Lignoceric-acid (0.81-1.08%; 0.77-1.08%), trans-palmitoleic-acid (0.22-0.29%; 0.26-0.37%), trans-oleic-acid (0.55-0.72%; 0.68-0.84%), trans-linoleic-acid (0.38-0.54%; 0.42-0.59%) respectively for non-pregnant and pregnant women. Furthermore, total FAs were significantly (p ≤ 0:05) higher in women aged 31-45 years than in women aged 16-30 years. whereas, there was no significant change in total FAs profile based on omega-supplementation, diet category, preterm-birth history, and gestation period. Thus, the current study provides information about an individual who is deficient in FAs and the dose required to increase FA concentrations in the body.
RESUMEN
Prebiotics are either natural or synthetic non-digestible (non-)carbohydrate substances that boost the proliferation of gut microbes. Undigested fructooligosaccharides in the large intestine are utilised by the beneficial microorganisms for the synthesis of short-chain fatty acids for their own growth. Although various food products are now recognized as having prebiotic properties, several others, such as almonds, artichoke, barley, chia seeds, chicory, dandelion greens, flaxseeds, garlic, and oats, are being explored and used as functional foods. Considering the benefits of these prebiotics in mineral absorption, metabolite production, gut microbiota modulation, and in various diseases such as diabetes, allergy, metabolic disorders, and necrotising enterocolitis, increasing attention has been focused on their applications in both food and pharmaceutical industries, although some of these food products are actually used as food supplements. This review aims to highlight the potential and need of these prebiotics in the diet and also discusses data related to the distinct types, sources, modes of action, and health benefits.
