Some fats (and the fatty acids they contain) are very important during pregnancy because they support your baby’s brain and eye development both before and after birth (see DHA supplementation below as a critical supplement).
Fats also help the placenta and other tissues grow. Some studies show that some fats may help prevent preterm or low birth weight. Stick to mono and polyunsaturated fats that include safflower, olive, canola, avocado and nut butters, cold-water fish oils and flax oil.
Avoid saturated and partially hydrogenated trans fats like high-fat meats, tropical oils, butter, margarine and lard. Also avoid trans fats that are found often in many processed foods like cookies, crackers and other snacks.
