Following DIY (do it yourself) diets as well as consuming supplements exceeding by far the recommended daily intake levels, is common among athletes; these dietary habits often lead to an overconsumption of some macro and/or micronutrients, exposing athletes to potential health risks. The aim of this study is to document the development of possible adverse effects in a 33 year-old amateur bodybuilder who consumed for 16 years a DIY high protein diet associated to nutrient supplementation. Body composition, biochemical measures and anamnestic findings were evaluated. We present this case to put on alert about the possible risks of such behavior repeated over time, focusing on the adverse gastrointestinal effects. We discuss the energy and nutrient composition of his DIY diet as well as the use of supplements.
This study provides preliminary data of the potential risks of a long-term DIY dietary supplementation and a high protein diet. In this case, permanent abdominal discomfort was evidenced in an amateur body builder with an intake exceeding tolerable upper limit for vitamin A, selenium and zinc, according to our national and updated recommendations. As many amateur athletes usually adopt self-made diets and supplementation, it would be advisable for them to be supervised in order to prevent health risks due to a long-term DIY diet and over-supplementation.
遵循自行搭配的饮食以及摄入远超推荐每日摄入量的补充剂，在运动员中很常见；这些饮食习惯往往会导致某些宏量营养素和/或微量营养素摄入过量，使运动员面临潜在的健康风险。本研究的目的是记录一名33岁的业余健美运动员的情况，该运动员连续16年食用自行搭配的高蛋白饮食并补充营养剂，评估其身体成分、生化指标和既往史。我们展示这个案例，以提醒人们长期重复此类行为可能存在的风险，重点关注胃肠道不良反应。我们讨论了他自行搭配饮食的能量和营养成分以及补充剂的使用情况。
本研究提供了长期自行搭配饮食补充营养剂和高蛋白饮食潜在风险的初步数据。在这个案例中，一名业余健美运动员出现了持续的腹部不适，根据我国最新建议，其维生素A、硒和锌的摄入量超过了可耐受上限。由于许多业余运动员通常采用自行搭配的饮食和补充剂，建议对他们进行监督，以预防长期自行搭配饮食和过度补充营养剂带来的健康风险。
