Supplementation with Folic Acid or 5-Methyltetrahydrofolate and Prevention of Neural Tube Defects: An Evidence-Based Narrative Review.

Folic acid (FA), which in its chemical form is pteroylglutamic acid, is the fully oxidised, water-soluble, monoglutamic form of vitamin B9. This compound is part of the folate group but with higher bioavailability, and it is found in vitamin supplements and fortified foods and drugs. Folate metabolism is complex and associated with various metabolic pathways, all of which confer protection on the cell and allow its survival.

Impact of nutrition on hearing loss.

The incidence of hearing disorders is rising at an alarming rate, aggravated by increasing longevity, without sufficient social awareness and attention from public health officials. The etiology of hearing loss (HL) is multifactorial, including both genetic and environmental factors, such as noise, ototoxic drugs, and nutritional status. Therefore, it is necessary to expand knowledge about the relationship between the different factors involved as a first step towards prevention and potential repair of hearing damage before it becomes irreversible and significantly limits the quality of life.

Drug Consumption and Hydration Status: Analysis of the Associations in an Elder Population.

Hydration status plays a key role in healthy ageing, and it is potentially affected by several factors, including drug consumption. However, research on this issue to date is scarce, especially in highly vulnerable groups, such as the elderly. We aimed to study the relationship linking hydration status, analysed by means of a validated questionnaire, 24 h urine analysis, body composition assessment, and drug consumption in a sample of old adults.

Nutritional Status of Breastfeeding Mothers and Impact of Diet and Dietary Supplementation: A Narrative Review.

Adequate nutrition during breastfeeding is crucial for ensuring the good health of mothers and babies. Despite the high energy and nutrient demands of breastfeeding, lactating women are often vulnerable from a nutritional perspective. The nutritional focus during breastfeeding tends to be on the newborn, often neglecting the mother's diet.

Hearing Function and Nutritional Status in Aviation Pilots from Spain Exposed to High Acoustic Damage.

Noise-induced hearing loss is the most frequent and preventable occupational disease. Aviation pilots are a vulnerable population, as they spend many hours exposed to noise pollution in their working environment. Different studies suggest that certain dietary compounds may play a key role in the etiology and prevention of this pathology.

Association between Hydration Status and Body Composition in Healthy Adolescents from Spain.

At present, obesity and overweight are major public health concerns. Their classical determinants do not sufficiently explain the current situation and it is urgent to investigate other possible causes. In recent years, it has been suggested that water intake could have important implications for weight management.

Influence of Water Intake and Balance on Body Composition in Healthy Young Adults from Spain.

The increasing prevalence of overweight and obesity has become an epidemic public health problem worldwide. In the last years, several investigations have suggested that water intake and retention could have important implications for both weight management and body composition. However, there is a lack of information about this issue globally, and mainly specifically in Spain.
