Why YSK: consuming too much sodium can lead to high blood pressure, increasing the risk of heart disease and stroke. In my country (USA), the average daily sodium intake is over 3,300mg, exceeding the recommended maximum of 2,300mg. The World Health Organization (WHO) recommends an even lower maximum of 2,000mg.
Also: with the rising cost of food, being mindful of additives that increase sell weight is important.
I’d also add that if you cook those plumped up chicken breasts, they will immediately release all that extra brine into your dish and ruin it. Buy normal-size chicken breasts and resist the urge to go for the “best” weight to price ratio.
