GLOSSARY

Kidney-Friendly Diet is an individualized kidney-related eating plan rather than one universal list of foods to avoid.

A renal diet is individualized to kidney function, laboratory results, treatment, medication and nutritional status. Protein, sodium, potassium, phosphorus and fluid are separate decisions, not automatic restrictions for everyone. Excessive restriction can worsen dietary adequacy and muscle loss. Potassium-containing salt substitutes and some supplements need particular review. An athlete with kidney disease should receive coordinated clinical nutrition care rather than importing a high-protein or electrolyte-loading strategy from healthy training partners without assessment.

Protein targets depend on body size, training, energy intake, age and clinical status. A high-protein label does not identify the actual amount, amino-acid quality or distribution. During weight reduction, adequate protein and resistance exercise can help preserve lean tissue, but neither removes the consequences of an excessive energy deficit. Kidney disease can require a different clinical approach. Do not transfer a healthy athlete's protein strategy directly to a person with impaired renal function.

An adequate diet provides sufficient energy and essential nutrients while fitting health needs. A high score for variety or a healthy food label cannot independently demonstrate adequacy. Review what is actually eaten, including foods excluded and suitable replacements. Athletes can consume many vegetables yet still lack enough energy or carbohydrate for training. Assess the overall pattern, distribution and relevant nutrient risks rather than assuming that a single food or supplement makes the entire diet balanced.

For example, a kidney-related laboratory change should prompt review of treatment, food and supplements with the renal team. Do not automatically remove every fruit, dairy food and protein source. Decide which nutrients actually need modification, retain adequate energy and review the plan as kidney function and laboratory findings change.

Blood pressure assessment depends on appropriate measurement and repeated interpretation, not one anxious or post-exercise reading. Sodium reduction and a suitable dietary pattern can help management, while potassium advice must account for kidney function and medication. Salt substitutes containing potassium are not suitable for everyone. An athlete's sweat-related electrolyte plan and a clinical hypertension plan require coordination. Do not assume that sweating heavily eliminates the need to assess persistent high blood pressure or prescribed treatment.

Clinical nutrition translates assessment into an individualized intervention and evaluates the response. A disease name alone cannot define the prescription: disease stage, medication, symptoms, laboratory findings, intake and functional goals matter. Screening identifies possible risk, whereas a full assessment supports a nutrition diagnosis and care plan. A sports context adds training demands but does not remove clinical requirements. Coordinate care when medical and performance objectives interact instead of applying a standard athlete menu to every patient.

Laboratory markers provide information within a clinical context rather than a complete nutrition diagnosis. Albumin and prealbumin are affected by inflammation, fluid balance, organ function and other processes, so they should not be interpreted as direct isolated measures of protein intake or muscle mass. A reference interval is not automatically the optimal target for an athlete. Combine relevant tests with intake, physical findings, symptoms and trends, and consider the method and timing before attributing a result to diet alone.
