Sweetcorn
Sweetcorn is safe throughout pregnancy in all forms — fresh, frozen, tinned, or on the cob. It provides fibre, folate, and B vitamins.

Sweetcorn is completely safe to eat during pregnancy in all its forms. Fresh corn on the cob, frozen sweetcorn, tinned sweetcorn, and popcorn are all safe. There is no specific concern about sweetcorn during pregnancy. It provides dietary fibre, which is helpful for managing constipation that is common in the second and third trimesters. It also contains folate, thiamine (vitamin B1), niacin (B3), vitamin C, and potassium. As a starchy vegetable, sweetcorn provides slow-release energy. Tinned sweetcorn is convenient, affordable, and retains most of its nutritional value during the canning process — drain and rinse if you want to reduce the sodium content of salted varieties. Frozen sweetcorn is equally nutritious and easy to add to soups, stir fries, and pasta dishes. Corn on the cob boiled or barbecued is a satisfying seasonal food. Popcorn (air-popped or lightly salted) is a reasonably nutritious snack option, though heavily sweetened or heavily buttered varieties are best in moderation. There is nothing in sweetcorn that is harmful or needs to be avoided during pregnancy.
