Dangerous fruits?

So yesterday, I did some grocery shopping and decided to buy more produce than I normally do. I bought some grapes and pineapple, among others. I had a pretty sizable bowl of grapes as a snack while playing a board game with my son. Fast forward to last night. I'm laying in bed, winding down. I usually google random things that pop into my head so I was looking up what's really healthy for pregnant women and what should be avoided. And to my surprise, it said that I should be avoiding GRAPES of all things! It said they have high levels of resveratrol which can cause toxicity issues in pregnant woman! So I started freaking out. I did more research and noticed that tons of pregnant women have eaten grapes often during pregnancy and they and their babies were fine. I've heard bad things about pineapple too but I've been told I'd have to eat tons of it to cause any problems. I noticed how old the conversations were so I decided to create a thread of my own to discuss it! So what are your experiences with grapes and pineapple or even papaya while pregnant? Did anything happen as a result of consuming said fruits? Has anyone heard of these precautions and asked your doctor? If so, what did they say? I emailed my doctor last night but I'm still waiting to hear back from her.

Any feedback would be appreciated! Thanks!
