5.Greens and Kidney Stones?
These greens have a lot of oxalate, which can cause kidney stones. If you’re at risk, your doctor may recommend no more than 40-50 milligrams (mg) of oxalate a day. And half a cup of greens can have close to 10 mg of it. So you can have a couple of servings, but don’t pack huge amounts into your green smoothies. One cup of raw spinach leaves has about 656 mg of oxalate.
6.Too Much of the Wrong Fish
Fish are rich in protein, low in saturated fats, and high in good fats your body needs. The catch? They absorb mercury. That’s a problem for anyone, but especially pregnant women because it can harm the baby’s nervous system.
Each week, you can eat 8 to 12 ounces — about two meals — of low-mercury fish like shrimp, canned light tuna, or salmon.
