GLOSSARY

High-Potassium Diet emphasizes potassium-containing foods when appropriate, with kidney function and medication affecting suitability.

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.

Cardioprotective eating commonly emphasizes vegetables, fruit, legumes, whole grains, nuts and suitable unsaturated-fat sources while improving the quality of fat and reducing excessive sodium. Benefits depend on what replaces the foods reduced. Clinical lipid and blood-pressure goals require broader assessment, including medication when indicated. Athletes should adapt portions and carbohydrate supply to training rather than assuming a heart-supporting pattern must be low in energy, extremely restrictive or unsuitable for fueling exercise.

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.
