What are antioxidants?5 answersAntioxidants are substances that protect cells from oxidative damage caused by free radicals and chain reactions. They can be found in antioxidant-rich foods, supplements, and herbs. Antioxidants are used as food additives to prevent food spoilage, particularly in frozen or refrigerated food. They are also used in industrial goods, such as fuels and lubricants, as stabilizers. Antioxidants inhibit the oxidation of unsaturated components in fats and oils, thereby enhancing shelf life and preserving the quality of lipid-containing foods. Some common antioxidants include vitamins E and C, beta carotene, lutein, and lycopene. Antioxidants play a significant role in preventing diseases and chronic illnesses associated with free radicals, such as cancer, Alzheimer's disease, and arthritis. The use of antioxidants in food is regulated for safety and toxicology aspects.
How do antioxidants work?4 answersAntioxidants work by neutralizing and reducing the negative impact of oxidants in the body. They achieve this by donating an electron to oxidant compounds, inhibiting their activity. Antioxidants can be classified into two categories: antioxidant enzymes and non-enzyme antioxidants. Antioxidant enzymes include superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx). Non-enzyme antioxidants are found in many vegetables and fruits and include compounds such as reduced glutathione (GSH), vitamin C, vitamin E, β-carotene, flavonoids, isoflavones, flavones, anthocyanins, catechins, isocatechins, and lipoic acid. The effectiveness of antioxidants depends on their redox status, and in some cases, they can have pro-oxidant effects. The use of metal-based antioxidants and nanomaterial encapsulation has been explored to enhance antioxidant activities.
What does antioxidants do?3 answersAntioxidants are substances that protect cells from oxidative damage caused by free radicals. They have anti-aging, anti-inflammatory, and disease-preventing properties. Antioxidants can be found in various sources such as food, plants, and dietary ingredients. They work by preventing the oxidation of molecules and scavenging free radicals, thus reducing cellular damage. Antioxidants play a crucial role in maintaining cellular health and viability by protecting cellular components like DNA, proteins, and lipids. They are used as food additives to prevent food spoilage and as stabilizers in industrial goods. In the field of oral health, antioxidants have shown promise in treating oral lesions and diseases. Additionally, antioxidant supplementation has been found to improve oocyte maturation, cell division, and embryo quality in bovine. Non-enzymatic antioxidants have been found to be more effective in supporting embryonic development in vitro.

What is an adequate level of selenium?
5 answers
The adequate level of selenium varies depending on the population and health conditions. In the general adult Taiwanese population, a normal selenium range is considered to be between 125-183 μg/L, with levels below 98.8 μg/L indicative of deficiency and requiring supplementation. For patients with Ataxia-Telangiectasia (A-T), nearly 40% had selenium levels below the reference value, emphasizing the importance of assessing selenium status in such patients. In broiler chicks, the minimum selenium requirement for growth was found to be 0.025 μg Se/g diet, with enzyme activities showing defined plateaus above certain selenium levels. Patients with Common Variable Immunodeficiency (CVID) showed inadequacy in selenium levels, with a significant correlation between selenium plasma levels and apolipoprotein A-1 concentrations, highlighting the importance of selenium in reducing cardiovascular risk in these patients.
