Hair loss affects self-image and mental well-being, yet evidence on whether diet can prevent or improve it has been inconsistent. To clarify the picture, researchers systematically reviewed human studies examining how individual foods, nutrients, and supplements influence hair health. They analyzed 17 studies involving over 61,000 participants, mostly women, spanning childhood to older age. Only studies on specific foods or nutrients were included, not whole-diet patterns. The studies examined a range of hair-related conditions, including alopecia areata (a patchy, autoimmune form of hair loss... diet micronutrients protein supplements vitamin d Hair

[toc position='left'] Introduction Lactobacillus reuteri is a bacterium found in the digestive tracts of mammals, including humans, and in fermented foods. It is a member of the genus Lactobacillus, which comprises most of the bacteria that live on and in the human body. Lactic acid-producing bacteria, such as those in the Lactobacillus genus, are commonly used in probiotic supplements.[ref doi='10.1016/j.tim.2021.01.003'] Furthermore, some online resources provide step-by-step instructions for at-home bulk production of yogurt with L. reuteri enrichment.

Bone mass decreases markedly with aging, compromising overall fitness and contributing to fractures and falls, especially among older adults living in residential care. Evidence indicates that nutritional factors play critical roles in maintaining bone mass and overall health. Findings from a recent study suggest that dietary protein and calcium reduce the risk of fractures and falls in older adults. Calcium participates in many aspects of human health, but it is perhaps best known for its role in bone health. The body maintains very tight control over the calcium circulating in the blood at ... dairy nutrition bone calcium protein

Depression and anxiety are neuropsychiatric diseases characterized by neurological dysfunction and poor mental health. Oxidative stress, which is caused by an imbalance in the concentration of reactive oxygen species and antioxidant compounds, may be one driver of neurological damage in the development of depression and anxiety. Findings of a new report demonstrate the ability of methyl donor supplementation to reduce oxidative stress in the brain and relieve depression and anxiety symptoms in rats eating a high-sugar diet. Methyl donors (e.g., choline, betaine, folate, vitamin B12) are nutrie... brain depression anxiety
