AI Article Synopsis
- Dairy products are crucial for calcium intake, but declining consumption leads to health issues like osteoporosis and fractures in adults.
- The study explores creating a homemade calcium-enriched, lactose-reduced milk using eggshell and kefir, measuring key components during preparation.
- Results indicate the new beverage has lower lactose and higher calcium than untreated milk, with similar intestinal absorption rates, while increasing urinary calcium excretion in human participants.
Article Abstract
Dairy products are the main source of calcium (Ca), but the loss of the consumption habit contributes to low consumption in adulthood, which leads to osteoporosis and increased fracture risk. Domestic use of kefir is straightforward and the eggshell is a natural discarded source of Ca. This paper proposes the development of an enriched Ca reduced lactose milk using eggshell and kefir. During the in vitro preparation, the pH, Ca and lactose contents were measured. Ca intestinal absorption of untreated milk and milk with kefir was compared. Finally, human volunteers consumed this dairy product and 24-h urine Ca was measured. Results showed that the beverage has lower lactose and higher Ca than untreated milk and milk with kefir. Intestinal Ca absorption was not different between both milks and an increase in urinary Ca excretion was observed in humans. This study provides a methodology to prepare at home a dairy product that could contribute to improve the Ca intake in adults.

This study investigated the protective effects and Pb-excretion mechanisms of yeast glucans (YG) with varying oxidation degrees in Pb-exposed mice. Results demonstrated that all three glucans effectively reduced blood lead levels, alleviated inflammation, and mitigated liver damage in Pb-exposed mice, with highly oxidized yeast glucan (OYG2) exhibiting the greatest efficacy. Furthermore, the glucans attenuated Pb-induced oxidative stress and pathological changes in the kidney by elevating glutathione and superoxide dismutase levels, thereby restoring renal excretory function (blood urea nitrogen and creatinine).

Increasing prevalence of childhood obesity has emerged as a critical global public health concern. Recent studies have challenged the previous belief that obesity was solely a result of excessive caloric intake. Alterations in early-life gut microbiota can contribute to childhood obesity through their influence on nutrient absorption and metabolism, initiation of inflammatory responses, and regulation of gut-brain communication.

Small intestinal organoids are similar to actual small intestines in structure and function and can be used in various fields, such as nutrition, disease, and toxicity research. However, the basal-out type is difficult to homogenize because of the diversity of cell sizes and types, and the Matrigel-based culture conditions. Contrastingly, the apical-out form of small intestinal organoids is relatively uniform and easy to manipulate without Matrigel.

Vitamin B, or riboflavin, is essential for maintaining healthy cellular metabolism and function. However, its light sensitivity, poor water solubility, and gastrointestinal barriers limit its storage, delivery, and absorption. Selecting suitable nanomaterials for encapsulating vitamin B is crucial to overcoming these challenges.
