I'm a nutritionist who loves to shop at Costco — but there are 11 things I never buy there

• I don’t buy produce or spices in bulk because my two-person household won’t use them up fast enough.
• Frozen breakfast sandwiches and premade soups aren’t on my grocery list, either.

For me, vitamin supplements are not necessary.

If I’m going to eat pizza, I want to go all in.

It’s worth checking in with a healthcare provider or professional to see if you even need additional protein in your diet before committing to such bulk buys.
