Is milk, butter, cheese, meat & eggs bad for cholesterol. My LDL is high & was put on welchol (colesevelam) just for 4 months. Is dairy ok for people with diabetes.

Yes yes yes yes yes. Granted, lowfat or skim milk wouldn't contain too much fat, and neither would egg whites isolated from the yolks, but in general the foods you listed are good sources of bad fats and should generally be limited.
