What foods to avoid

Week 8.5 here, first pregnancy. Have stopped my usual daily morning coffee since suspecting my pregnancy. Changed the tea at home to caffeine-free tea. Still drinking cold drinks esp when outside because the hot drinks are all coffee/tea and hot milo at hawker/coffeeshops can be way too sweet. My gynae says it's totally fine though, no need to avoid, 1 cup of coffee/tea a day is definitely okay.
