For certain people with salt-sensitive blood pressure or diseases such as Ménière's disease, this extra intake may cause a negative effect on health. WHO guidelines [4] [5] state that adults should consume less than 2,000 mg of sodium/day (i.e. about 5 grams of traditional table salt), and at least 3,510 mg of potassium per day. [6]
UK: The Food Standards Agency defines the level of salt in foods as follows: "High is more than 1.5 g salt per 100 g (or 0.6 g sodium). Low is 0.3 g salt or less per 100 g (or 0.1 g sodium). If the amount of salt per 100 g is in between these figures, then that is a medium level of salt."
This change has been shown to blunt the effects of excess salt intake on hypertension and cardiovascular disease. [1] [40] It has also been suggested that salt substitutes can be used to provide an essential portion of daily potassium intake, and may even be more economical than prescription potassium supplements. [41]
During the high-salt week, people ate their normal diet, along with two bouillon packets, each containing 1,100 milligrams of sodium. During the low-salt week, people ate foods with low sodium ...
A bit of salt in the diet is necessary for good health. The seasoning is also a kitchen staple and taste booster, but Americans consume way too much — usually without even picking up a saltshaker.
A low sodium diet has a useful effect to reduce blood pressure, both in people with hypertension and in people with normal blood pressure. [7] Taken together, a low salt diet (median of approximately 4.4 g/day – approx 1800 mg sodium) in hypertensive people resulted in a decrease in systolic blood pressure by 4.2 mmHg, and in diastolic blood pressure by 2.1 mmHg.
The recommended adequate intake of sodium is 1,500 milligrams (3.9 g salt) per day, and people over 50 need even less." [13] The Daily Value for potassium, 4,700 mg per day, was based on a study of men who were given 14.6 g of sodium chloride per day and treated with potassium supplements until the frequency of salt sensitivity was reduced to 20%.
