The most reliable places to find sound nutritional advice are:

1. A registered dietitian nutritionist — RDN
   This is the best source for personalized advice, especially for pregnancy, weight loss, diabetes, cholesterol, digestion, or athletic goals. You can search for one through the Academy of Nutrition and Dietetics’ “Find a Nutrition Expert” directory.

2. Your OB/GYN or midwife
   For pregnancy nutrition, start with the clinician managing the pregnancy. They can advise on prenatal vitamins, iron, folic acid, weight gain, nausea, gestational diabetes risk, and food-safety concerns.

3. ACOG — American College of Obstetricians and Gynecologists
   ACOG has patient-friendly pregnancy nutrition guidance on healthy eating, vitamins, minerals, and food choices during pregnancy.

4. USDA MyPlate / Nutrition.gov
   Good for basic food-group guidance, meal planning, pregnancy and breastfeeding nutrition, and practical plate-building advice. Nutrition.gov has a pregnancy section that includes foods to eat, foods to avoid, supplements, and weight gain.

5. CDC and FDA
   Best for food safety: listeria, mercury in fish, deli meats, unpasteurized foods, raw seafood, and other pregnancy-related food risks. CDC notes pregnant women are more likely to get sick from certain foodborne germs such as Listeria.
