Briefly discuss why americans are encouraged to aim for the recommended levels of sodium and potassium in their diets in relation to disease prevention

Many Americans eat way too much sodium in their daily life, they are encouraged to have more potassium to counter act the sodium. High levels of sodium increases the risk of heart disease and even death. Reducing it or countering it with proper amounts of potassium reduces the risk of high blood pressure, stroke, heart failure, kidney damage, and heart disease.

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
