Performance is important at every stage of our lives, whether we're young and in school, or as we age, during both work and play -- whether mental, physical (e.g., endurance vs. strength), or even creative performances.   Our performance can be affected by the interplay between our genetics and many aspects of our environment, including being breast fed as infants. Genetic variations can interact with certain vitamins, dietary fats including omega-3 fatty acids, stress, social environment, quality of sleep, or exposure to oxidative stress or environmental contaminants like lead (Pb).  Information on elite athleticism, and even controversial approaches to enhancement of performance and appearance are beginning to emerge.   Below are just a few examples of recent articles which touch on performance. Members can stay abreast of new research on topics of special interest to themselves, family members, or colleagues.  Join us today.     Nature and Nurture®
