okay thanks for the info re very active and fit. can you give me some idea of your diet? a sample showing 3 days' worth (2 work days, 1 day off) of breakfasts, lunches, dinners, snacks, and fluids could be very telling.
sorry this abstract comes across a little condescending in tone, i didn't write it
Practical issues in nutrition for athletes
http://www.tandfonline.com/doi/abs/10.1 ... 9508732281"Many athletes do not achieve sound nutritional practices to optimize their sports performance. Factors include poor nutrition knowledge, dietary extremism, poor practical skills in choosing or preparing meals, and reduced access to food due to a busy lifestyle and frequent travel. Education in nutrition for the athlete needs to be practical, so as to address eating strategies and key food and fluid choices that will help to achieve the goals of sound nutrition. Strategies that can achieve a number of nutritional goals simultaneously are most useful, since athletes often find it difficult to integrate separate issues. Athletes with extreme nutrient requirements, or with nutritional problems, should seek individual assessment and counselling from a sports nutrition expert."
here's a decent one
Elite Athlete Immunology: Importance of Nutrition
https://www.thieme-connect.com/ejournal ... -2000-1451"Immunosuppression in athletes involved in heavy training is undoubtedly multifactorial in origin. Training and competitive surroundings may increase the athlete's exposure to pathogens and provide optimal conditions for pathogen transmission. Heavy prolonged exertion is associated with numerous hormonal and biochemical changes, many of which potentially have detrimental effects on immune function. Furthermore, improper nutrition can compound the negative influence of heavy exertion on immunocompetence. An athlete exercising in a carbohydrate-depleted state experiences larger increases in circulating stress hormones and a greater perturbation of several immune function indices. The poor nutritional status of some athletes may predispose them to immunosuppression. For example, dietary deficiencies of protein and specific micronutrients have long been associated with immune dysfunction. An adequate intake of iron, zinc and B vitamins is particularly important but the dangers of over-supplementation should also be emphasized; many micronutrients given in quantities beyond a certain threshold will in fact reduce immune responses and may have other toxic effects that are detrimental to health. Although it is impossible to counter the effects of all of the factors that contribute to exercise-induced immunosuppression, it has been shown to be possible to minimize the effects of many factors. Athletes can help themselves by eating a well-balanced diet that includes adequate protein and carbohydrate, sufficient to meet their energy requirements. This will ensure a more than adequate intake of trace elements without the need for special supplements. Consuming carbohydrate (but not glutamine) during exercise attenuates rises in stress hormones such as cortisol and appears to limit the degree of exercise-induced immunosuppression. By adopting sound nutritional practice, reducing other life stresses, maintaining good hygiene, obtaining adequate rest and spacing prolonged training sessions and competition as far apart as possible, athletes can reduce their risk of infection."
i have a friend who is very athletic and had some health issues. i suggested she start on a supplement regimen as she was doing so poorly i thought it would be a bad idea for her to wait until some baseline testing was done. anyway long story short she is seeing major improvements using a regimen i suggested, and all her bloodwork came back suboptimal. the doc said everything was normal but all her levels are right at the bottom end of the normal range, which does in fact include a lot of sick people. in some cases, the 'normal range' is pretty much all sick people.
docs don't tend to do adequate nutritional bloodwork, and they're even less likely to understand what they're looking at when they do. but, if you're interested in the nutrition angle, the next step is that 3 day diet diary. then the bloodwork. it doesn't pay to just throw things in willy nilly without knowing exactly what you're trying to achieve and then afterwards, whether your efforts were effective.
