While peanut butter may feel like a guilty pleasure food, it's actually full of valuable nutrients (via Healthline). If your body is in need of the nutrients that peanut butter contains, you're likely to get a craving for it. Peanut butter is high in antioxidants, which are an important part of any diet, and you may be craving peanut butter when your body is looking for an extra boost. As a low-carbohydrate food, peanut butter can be a great snack for folks with gestational diabetes who need to keep their carbs in check.

Peanut butter is a great way to get plant-based protein which makes it a perfect choice for pregnant folks who don't eat meat or dairy (via Cary OB/GYN). In addition to protein, it's also a source for healthy fats, and peanut butter is a high-fiber food. Since many pregnant folks struggle with constipation, the fiber in peanut butter can be an easy way to keep those symptoms at bay.
