- People with a reduced ability to absorb dietary fat. Because vitamin A is a fat-soluble vitamin, fat is required for its absorption. Some conditions that can cause fat malabsorption include Crohn's disease, cystic fibrosis, celiac disease, pancreatic enzyme deficiency, and liver disease.
- Children living in developing countries.
Tips for Increasing Your Vitamin A Intake:
- Pack cut carrots in your lunch for an afternoon snack.
- Slice a peach, mango, or apricot on to your breakfast cereal or oatmeal.
- Substitute a sweet potato for your baked potato.
- Eat fruits and vegetables raw whenever possible. Vitamin A can be lost during preparation and cooking.
- Steam vegetables, and braise, bake, or broil meat instead of frying. This will help retain some of the vitamin content.
