I dont normally use much salt in cooking or at the table. - a running joke at my house is that I say things are too salty or too sweet.  Lately, Ive noticed that I can pick up on an extra salty taste in many foods (things like processed meats are out of the question).  I donate plasma 2x a week and have been OK for blood pressure.  59 years old.  Dont eat much meat, dont eat/enjoy sweets, drink lots of water, juice  veggies/fruits 2x/week.  1 - 2 wine/day.
Hello, Thanks for posting your query. Since you donate plasma, sodium concentration in your blood stream will be high, resulting in increased salty taste in your mouth. It can also be due to altered taste sensation. Depapillation of tongue also can cause this. I would advise you to take a balanced diet. This is not a serious concern. Please avoid unnecessary worries. I wish you good health. Take care.
