Final answer:
The USDA recommends an intake limit of 2,300 milligrams of sodium per day for Americans, as excessive intake from processed foods can lead to health risks such as hypertension.
Step-by-step explanation:
According to the most recent Dietary Guidelines by the United States Department of Agriculture (USDA), it is recommended that Americans consume a maximum of 2,300 milligrams of sodium per day.
The use of sodium as a preservative in processed foods significantly contributes to the average American's intake, which exceeds this recommended amount. Reading food labels is suggested to monitor and manage sodium consumption effectively, aiming to limit intake for better health outcomes and reducing the risk of hypertension.
