If you choose to be a vegetarian, the first thing you should care about is to have the right diet plan that includes all necessary nutrients. The main concern here is iron.  According to the regulations of the US National Institute of Health, the recommended dietary allowances of iron for adults is 8-27 mg per day, with pregnant and breastfeeding women tending to the higher end.

There are plenty non-meat options that contain the same amount of iron (or in some cases even more) than meat.

Here are top 14 of these vegetarian foods:

1. Spinach.
2. Broccoli.
3. Lentils.
4. Kale.
5. Swiss chard.
6. Bok choy.
7. Baked potato.
8. Sesame seed.
9. Cashew.
10. Soybeans.
11. Chickpeas.
