Final answer:
The answer is b) False. The majority of adults do not meet the daily recommendation for potassium, which is 4700 mg per day. Consuming high-potassium foods is essential for maintaining a healthy balance of this nutrient in the body.
Step-by-step explanation:
Most adults do not meet or exceed their daily recommendation for potassium, so the correct answer is b) False. The daily intake of potassium should be 4700 mg. However, many individuals tend to consume too much sodium and too little potassium, disrupting the balance necessary for healthy cellular function. Potassium is vital for the maintenance of normal potassium concentration gradients between the intracellular fluid (ICF) and extracellular fluid (ECF) and is regulated by the kidneys, with the renal tubules actively and passively excreting potassium, influenced by aldosterone and reliant on basolateral sodium-potassium pumps.
A person who is deficient in potassium may experience disruptive effects on the membrane components due to excess sodium. Therefore, to achieve adequate potassium levels, individuals should increase intake of high-potassium foods such as bananas, leafy greens, and avocados.
