Actually, all the potatoes that grow here are pretty much tasteless.
US: Speaking about tasteless vegetables. Carrots, in general are usually tasteless. There's a Spanish market nearby where the carrots are really yucky. When my father grew carrots, they had somewhat of a bitter taste. They were stubby because of the clay soil. "You", the vegetables, are what you eat.
I get migraines and the triggers are two fold:
1) How fast environmental variables change
1a) The absolute value of the magnitude of barometric pressure vs time (I have a value)
1b) how fast the temperature changes (15 degrees in 10 hours is too much)
2) Foods (probably additives)
#1: Neutrasweet and artificial sweetners - a small amount
#2: Vinegar: Vinegar and oil dressing - no; potatoe salad and cole slaw (maybe); Pickeled pigs feet: No
#3: Citric acid from a non-corn source: That was a tough one to figure out.
#4: Nitrates: dose dependent. One or two hot dogs is OK
#5: Dairy: particularly milk and ice cream. The product isn't totally avoided. Never liked milk since I was a baby.
#6: There is some ingredient in white bread that bothers me.
One oddity in this, is that I don't like milk and eggs, but they are a necessary ingredient. Egg Nog, I love.
I also have to limit chocolate.
The barometric pressure thing really messes everything up: blood pressure, breathing (Asthma), pulse oximitry, skin/hair oilyness
So, the environmental triggers and chocolate are acne vulgaris triggers. I have acne rosacia as well. It took a while to get this list together.
There might be a hereditary connection to skin diseases: e.g. seborehic dermatitis(dandruff), acne, psoriasis, ickthosis (fish skin)
