Are grapes safe for pregnancy? (1st trimester)

I'm 7w now, have been taking grapes for the past few days. (15 per serving). This morning I read an article here that grapes are a no-no because it has risk of resverastrol toxicity. 😵 My 1st scan and gynae visit is only Wed. Can anyone share if grapes are alright? What fruits should I avoid, and what should I eat? 😭
