Too many times I hear friends say, "not too much salt!" or, "oh, I don't add salt to anything" or, "salt is bad for you", to which I usually respond, "SALT IS GOOD!!" And it is. Let me explain why:
1) Salt enhances food's flavour. Salt brings to food far more than one of the five basic taste sensations (sweet, salty, sour, bitter and umami). Sweets taste sweeter. Salt masks bitter tastes, making naturally bitter foods like chocolate and broccoli become delicious. It brings flavours together, making them play in unison far better than without. I always recommend cooking with either sea salt or kosher salt versus table salt (or iodized salt). Kosher salt is additive-free, and has a lighter taste than iodized salt. Sea salt is, well, made from salt water; it contains trace minerals that aren't found in mined salts (Kosher and iodized are both mined).
2) You actually need salt in your diet.
