Sesame Seeds: A Nutrient-Rich Superfood

Sesame seeds (Sesamum indicum L.) have been cultivated for thousands of years and have long been celebrated for their culinary versatility. Beyond their delightful nutty flavor and crunchy texture, sesame seeds have also gained recognition for their remarkable health benefits. This article provides an in-depth exploration of the numerous ways in which sesame seeds contribute to overall well-being. Sesame seeds are a powerhouse of phytochemicals, including lignans derivatives, tocopherol isomers, phytosterols, and phytates, which have been associated with various health benefits, including the preservation of cardiovascular health and the prevention of cancer, neurodegenerative disorders, and brain dysfunction. These compounds have also been substantiated for their efficacy in cholesterol management. Their potential as a natural source of beneficial plant compounds is presented in detail. The article further explores the positive impact of sesame seeds on reducing the risk of chronic diseases thanks to their rich polyunsaturated fatty acids content. Nevertheless, it is crucial to remember the significance of maintaining a well-rounded diet to achieve the proper balance of n-3 and n-6 polyunsaturated fatty acids, a balance lacking in sesame seed oil. The significance of bioactive polypeptides derived from sesame seeds is also discussed, shedding light on their applications as nutritional supplements, nutraceuticals, and functional ingredients. Recognizing the pivotal role of processing methods on sesame seeds, this review discusses how these methods can influence bioactive compounds. While roasting the seeds enhances the antioxidant properties of the oil extract, certain processing techniques may reduce phenolic compounds.

Blood Phytosterol Concentration and Genetic Variant Associations in a Sample Population

The main objective of this study was to determine plasma levels of PS and to study SNVs rs41360247, rs4245791, rs4148217, and rs11887534 of ABCG8 and the r657152 SNV at the ABO blood group locus in a sample of a population treated at our hospital, and to determine whether these SNVs are related to plasma PS concentrations. The secondary objective was to establish the variables associated with plasma PS concentrations in adults. Participants completed a dietary habit questionnaire and a blood sample was collected to obtain the following variables: campesterol, sitosterol, sitostanol, lanosterol, stigmasterol, biochemical parameters, and the SNVs. In addition, biometric and demographic variables were also recorded. In the generalized linear model, cholesterol and age were positively associated with total PS levels, while BMI was negatively related. For rs4245791, homozygous T allele individuals showed a significantly lower campesterol concentration compared with C homozygotes, and the GG alleles of rs657152 had the lowest levels of campesterol compared with the other alleles of the SNV. Conclusions: The screening of certain SNVs could help prevent the increase in plasma PS and maybe PNALD in some patients. However, further studies on the determinants of plasma phytosterol concentrations are needed.

Hepatic dysfunction in patients receiving intravenous lipid emulsions

PURPOSE

Until recently, intravenous lipid emulsions (ILEs) have consisted of soybean oil (SO) only. This review addresses recent developments in the field, including the problem of intestinal failure associated liver disease (IFALD) that can occur with the use of ILEs in children and adults, and newer ILEs that may minimize and reverse IFALD.

RECENT FINDINGS

Cholestasis is the primary manifestation of IFALD in premature infants receiving ILEs, whereas in older children and adults, steatosis is predominant. Two alternative ILEs have been extensively investigated for both safety and efficacy. SMOF, an ILE containing medium chain triglyceride, soybean oil, olive oil and fish oil (FO), is now widely used in both children and adults. A newer FO ILE is approved for use in children only. However, in case reports FO ILE has been shown to improve IFALD in adults. A number of new studies suggest that cholestasis from ILEs is dose-related. IFALD does not improve in many patients after transition from SO to SMOF, but partial or complete replacement with FO can halt and reverse IFALD.

SUMMARY

Adverse hepatic effects from ILEs are to some extent dose-related. Overfeeding with fat or with carbohydrate, or simply providing excessive calories in general, may be responsible. More research is needed investigating dose-related effects of macronutrients on liver injury.
