Quick answer
Costco can be helpful if you buy repeat-use staples rather than oversized foods you may not finish. Focus on lean proteins, yogurt, eggs, freezer vegetables, gentle carbs, broth, and hydration options. Availability varies by location, and labels can change, so check current packaging.
Lean proteins
- Rotisserie chicken, with skin removed if grease bothers you
- Chicken breast, turkey breast, tuna packets, salmon, shrimp only if tolerated and appropriate for your household
- Eggs, egg whites, Greek yogurt, cottage cheese, and low-sugar protein shakes
- Extra-lean ground beef or lean ground chicken when available
Easy breakfasts
Look for Greek yogurt cups, eggs, oatmeal, cottage cheese, low-sugar protein shakes, fruit, and whole-grain toast options. Smaller breakfast portions may be easier than a large plate.
Freezer and pantry foods
- Frozen vegetables that can be steamed until soft
- Frozen fruit for smoothies
- Microwave rice or potatoes for small sides
- Broth, chicken soup, tuna, crackers, and applesauce for low-appetite days
Foods to be careful with
Large bakery items, fried appetizers, creamy dips, high-fat prepared meals, giant bags of chips, rich desserts, and oversized cheese-heavy meals may be harder to portion and may worsen nausea, reflux, burping, or fullness for some people.
