Possible Health Benefits Of Hemp Seeds During Pregnancy

Hemp hearts are a highly nutritious pregnancy superfood that contains several nutrients and minerals beneficial for you and your baby. Here’s how regular consumption of hemp seeds in moderation and as a part of a healthy, well-balanced pregnancy diet may benefit you.

Your body requires these nutrients to carry out different body functions essential for a healthy pregnancy. For instance, hemp seeds contain a considerable amount of iron which could help avert iron deficiency anemia (IDA) in pregnancy. IDA may lead to complications in the newborn, such as premature birth, low birth weight, or poor growth (6).
  1. Aid baby’s growth and development: Hemp hearts contain significant amounts of plant-based protein that can contribute to your total protein requirement. Pregnant women need more protein during pregnancy to support the growth of fetal tissue (including the brain) and breast and uterine tissues. Also, it plays a pivotal role in increasing your blood supply (7). Additionally, hemp seeds have high amounts of omega-3 fatty acids, such as DHA (docosahexaenoic acid), which help in healthy fetal brain and eye development (8).

  1. Keeps digestive system healthy: Expecting mothers between the ages of 19 and 30 require 28 to 36g of fiber per 1000 calories (5). Three tablespoons of hemp seeds offer 1.2 grams of dietary fiber, which can contribute to your total fiber needs (4). Consuming optimum amounts of fiber is vital to add bulk to the diet and maintain healthy bowel movements, which helps keep constipation and related issues away.
