In my home, my mother-in-law insisted I soak walnuts and almonds overnight because dry nuts produce 'garmi' in the body. It's a nice, simple ghar ki custom that really helped my digestion too.
Yes, walnuts are highly nutritious and good for early weeks. Even after my C-section, I continued eating them to help with healing and milk supply. Just start with 2-3 a day.
Walnuts are packed with DHA and folate which are excellent for baby's brain development. However, it's always best to ask your doctor about the exact quantity you should consume daily.
Personally, I ate 2-3 soaked walnuts every single day during my first trimester. I just found them easier to digest when soaked overnight rather than eating them dry.
When I was at my parents' house, my mom used to peel soaked walnuts for me every morning with my warm milk. It felt so comforting and kept my energy levels up during early months.
Yes, they are great for nutrients, but if you have thyroid issues like I did, make sure you don't take them close to your morning medicine. Always follow up with your doctor about your diet and reports.
