Actually, I am also trying to conceive and my mother-in-law said simple green veggies like turai are very good. It is light on the stomach and keeps your system clean.
Haan beta, turai toh bahot acchi hoti hai pregnancy mein. Hamare ghar pe toh sab bolte hain ki yeh thandi hoti hai aur digestion ke liye sabse best hai, bilkul khao.
Honestly, my gynac said turai is highly recommended because it has high water content and dietary fiber. It prevents constipation which is a huge issue during pregnancy, so definitely include it in your diet.
In my family, they make a wonderful turai kootu and my MIL insists it's very cooling. But I also checked with my doctor and she agreed it's highly nutritious, so you can have it without any worry.
Yes, you can surely eat turai, it's very safe and healthy. I had PCOS before conceiving so I was super careful about everything I ate, but simple home-cooked ridge gourd is great for digestion.
