Vitamin A is a nutrient that the body needs in small amounts to function and stay healthy. Vitamin A helps in vision, bone growth, reproduction, growth of epithelium (cells that line the internal and external surfaces of the body), and fighting infections. It is fat-soluble (can dissolve in fats and oils). Vitamin A is found in liver, egg yolks, and whole milk dairy products from animals and in fish oils. It can also be made in the body from a substance found in some fruits and vegetables, such as cantaloupes, carrots, spinach, and sweet potatoes. Vitamin A is being studied in the prevention and treatment of some types of cancer. Also called retinol.
According to a new study reported in Nature Scientific Reports, Methylene Blue, a century-old medication, can be a very efficient, broad-spectrum UV irradiation protector that absorbs UVA and UVB, repairs ROS and UV irradiation-induced DNA damage, and is safe for coral reefs.
Researchers have genetically engineered a probiotic yeast to produce beta-carotene in the guts of laboratory mice. The advance demonstrates the utility of work the researchers have done to detail how a suite of genetic engineering tools can be used to modify the yeast.
Neuroscientists agree that a person's brain is constantly changing, rewiring itself and adapting to environmental stimuli. This is how humans learn new things and create memories. This adaptability and malleability is called plasticity.
Scientists from Peter the Great St. Petersburg Polytechnic University (SPbPU) have successfully produced microalgae biomass that has a high content of carotenoid pigments, which is suitable for the food sector.
The study concludes that vegan diet has a broad effect on children's metabolism. Serum biomarker levels for vitamins A and D, cholesterol forms and essential amino acids were significantly lower in children on vegan diet compared to age-adjusted omnivores.
Carrots are a good source of beta-carotene, which is a precursor of vitamin A. But to get the full health benefits of this superfood, you need an active enzyme to produce this vitamin.
Whether tomatoes are fresh, cooked, juiced, or sun-dried, they are arguably one of the most multipurpose fruits on Earth.
In breakthrough colon cancer research, scientists at ChristianaCare's Helen F. Graham Cancer Center & Research Institute have discovered a link between two key signaling pathways crucial to the development and growth of colon cancer. The study is published today in the journal PLOS ONE.
More than two billion people worldwide suffer from micronutrient malnutrition due to deficiencies in minerals and vitamins.
A rice-based diet is a traditional food among certain east-Asian population and has ushered in several genomic adaptations that may play a role in obesity.
A new collaborative study led by researchers from the Spanish National Research Council (CSIC) at the Centre for Research in Agricultural Genomics (CRAG) in Barcelona and the Institute for Plant Molecular and Cellular Biology (IBMCP) in Valencia describes a promising strategy to improve the nutritional benefits of crops.
Cambridge scientists have developed a new way to fortify shellfish to tackle human nutrient deficiencies which cause severe health problems across the world. The team is now working with major seafood manufacturers to further test their microencapsulation technology, or "Vitamin Bullets".
Sweet potatoes are cultivated worldwide and are considered a major source of nutrition, especially in Asian and sub-Saharan African diets.
A team at the Centro Nacional de Investigaciones Cardiovasculares, working in partnership with researchers at Mount Sinai Hospital in New York, has discovered a new molecular mechanism mediated by nuclear receptors that determines the identity and expansion of macrophages--one of the cell types that act as immune sentinels in the body.
