In bodybuilders' diets, protein plays a crucial role in supporting muscle growth and repairing damaged muscle tissue. These individuals meet their protein needs by combining dietary sources with supplements. Animal-based proteins are often preferred over plant-based proteins because they are believed to better support muscle protein synthesis. ⋯ Nutritional factors, including protein content, amino acid profiles, and fat levels, significantly influence the preferences of bodybuilders and high-level meat consumers. However, it is crucial to maintain a balance by incorporating other essential nutrients such as carbohydrates, healthy fats, vitamins, and minerals to ensure a complete and balanced diet. The findings from this review can inform strategies and product development initiatives tailored to the needs of bodybuilders and discerning meat enthusiasts.

The aim of this scoping review was to characterize the diagnostic criteria, their cutoff values, and the prevalence of cachexia in Asians. We systematically reviewed studies involving Asian adult patients with cachexia due to cancer and chronic diseases other than cancer, such as heart and renal failure. Sources in English and Japanese published between December 2008 and April 2022, including observational, longitudinal, cross-sectional, and clinical trials, were examined. ⋯ The prevalence rates of cachexia were 3.4% to 66.2% and 6.2% to 93% in non-cancer and cancer patients, respectively. Several diagnostic criteria, such as BMI and muscle mass, have been used, which are affected by racial differences in body size. However, few studies have used cutoff values for Asians.

We investigate the accuracy and reliability of ChatGPT, an artificial intelligence model developed by OpenAI, in providing nutritional information for dietary planning and weight management. The results have a reasonable level of accuracy, with energy values having the highest level of conformity: 97% of the artificial intelligence values fall within a 40% difference from United States Department of Agriculture data. ⋯ These findings suggest that ChatGPT can provide reasonably accurate and consistent nutritional information. Further research is recommended to assess the model's performance across a broader range of foods and meals.

Osteoporosis constitutes a serious challenge for public health. Dietary patterns belong to important, modifiable risk factors of this disease. Therefore, what and in what quantities we consume on a daily basis are extremely relevant. ⋯ These dietary components include carotenoids. This paper presents a broad review of studies on the influence of particular carotenoids (β-carotene, lutein, zeaxanthin, β-cryptoxanthin, and lycopene) on bones. The paper discusses up-to-date in vitro experiments and research on animal models and presents how the results translate into clinical effect in humans.
