[toc position='left'] Introduction Light does much more than help us see. It tells the brain what time it is. That signal coordinates sleep and wakefulness, hormone release, metabolism, mood, and hundreds of other processes that follow a roughly 24-hour rhythm. Its effects depend not simply on how much light reaches the eye, but when it arrives. Bright light in the morning and throughout the day strengthens the body's daytime signal. Dim evenings and dark nights allow the biological night to unfold. Modern life often reverses that pattern, giving us biologically dim days and unusually bright n... metabolism sleep depression mental health melatonin eyes circadian rhythm

(https://www.foundmyfitness.com/newsletter) Protein is still (somehow) controversial. Should we restrict protein in favor of longevity and reducing cancer risk, or should we maximize our intake in favor of building muscle mass and enhancing performance? The answer lies somewhere in the middle. But one thing is for certain—the current recommendations don't accurately reflect the scientific evidence. That's why I sat down with Dr. Peter Attia as a guest on his ... aging cancer muscle strength protein exercise
Read moreWhen it comes to managing knee and hip arthritis, resistance exercise might be the ticket. A recent meta-analysis found that resistance exercise dramatically reduces pain and improves daily function in people with knee and hip arthritis. Researchers analyzed data from randomized controlled trials comparing resistance exercise to other interventions, including no treatment, other forms of exercise, non-exercise interventions, or a combination of these. They examined the effects on pain and function and the relationship between increased leg strength and improved outcomes. They included 250 stud... exercise arthritis

Cardiovascular disease is a major public health threat, with deaths from cardiovascular diseases expected to reach 23 million by 2030 (https://www.sciencedirect.com/science/article/pii/S0735109712053715). A diet rich in fruits and vegetables is known to reduce heart disease risk, in part due to the antioxidant and anti-inflammatory compounds provided by the diet that reduce oxidative stress and improve vascular function. Findings from a new report show that a supplement containing bromelain and anthocyanin antioxidants imp... polyphenol inflammation muscle blood pressure antioxidant cardiovascular supplements
Read more[toc position='left'] Polyphenols comprise a group of antioxidant compounds found in a variety of plants consumed as foods and beverages. Polyphenols are one of the most common classes of bioactive compounds found in plants, along with alkaloids (e.g., berberine (https://www.foundmyfitness.com/topics/berberine)), organosulfur compounds (e.g., sulforaphane), and terpenoids (e.g., beta carotene). A growing body of evidence suggests that polyphenols have disease-fighting properties, although the evidence to support these claims varies in quality. Research has demonstrated some degree of efficacy ... polyphenol brain cancer heart disease green tea gut diet microbiome microbes
Read moreBreast milk is a complex and highly dynamic fluid that contains both nutritional and non-nutritional components. Some of these components provide breast milk aroma and taste aspects, such as those associated with garlic or coffee, potentially influencing the breastfed infant's dietary preferences later in life (https://pubmed.ncbi.nlm.nih.gov/30982867/). Findings from a new study suggest that the non-nutritional compound piperine transfers into breast milk, providing pungent flavor aspects. Piperine is a bioactive compound found in black pepper that exerts anti-inflammatory, anti-pain, and an... nutrition breast milk

History The importance of zinc in the human diet first became apparent in the early 1960s, after a patient with a rare syndrome presented to Dr. Ananda Prasad, a physic... nutrition interesting zinc
Read more[toc position='right'] Resveratrol is a natural compound found primarily in the skin of red grapes and the root of Polygonum cuspidatum (also known as Japanese knotweed). It is also present to a lesser degree in peanuts and blueberries. Resveratrol protects the plants in which it is present from fungal attack and the damaging effects of ultraviolet radiation. Originally extracted in the 1940s, resveratrol attracted little interest in terms of human health until 1992 when research suggested that it could mediate some of the cardioprotective effects of red wine.[ref doi='10.3390/molecules220202... exercise resveratrol alzheimer's metabolism cardiovascular
