Final answer:
The recommended upper limit for daily sodium intake in the U.S. is less than 2300 mg. Checking food labels for sodium content and making dietary choices to consume less processed food can help maintain this recommended intake level.
Step-by-step explanation:
The upper limit for sodium intake per day in the U.S. is recommended to be less than 2300 mg. This recommendation is based on dietary guidelines aimed at maintaining a healthy lifestyle and avoiding excessive intake that could lead to health issues such as hypertension. Processed foods are a major source of added sodium, and it's important to avoid oversalting foods, check food labels for sodium content, and be aware of sodium in what you consume daily.
While the average sodium intake for Americans is around 3436 mg per day, it is important to strive for a lower intake as most adults only require about 500 mg of sodium each day for physiological functions. Foods considered low in sodium have less than 140 mg per serving or 5% of the daily value. By consuming less processed foods and being mindful of sodium intake, individuals can work towards maintaining a healthier intake level in line with dietary recommendations.
