Costco is not only about bulk buying; it also offers a variety of healthy food options. In this guide from Dr. Gundry, we explore some of the best choices for maintaining a nutritious diet while shopping at this popular warehouse store.

When looking for seafood, always opt for wild-caught options. Costco generally offers fresh and frozen wild Alaskan salmon, which is darker in color compared to farm-raised alternatives. Alaskan salmon is a reliable choice as it is legally required to be wild-caught, unlike Canadian or European options.

• Choose wild-caught Alaskan salmon for better health benefits.
• Canned sardines are recommended for their omega-3 content and natural calcium from bones.

For tuna, select those labeled as low in mercury. They primarily come from smaller, less-contaminated fish.

• Prefer goat or sheep milk cheeses over cow's milk for added health benefits.
• Check labels to ensure authenticity of origin, especially for Italian cheeses.

Nuts like pistachios, walnuts, and macadamia can be healthy options. However, it's advisable to select nuts still in shells as this slows consumption and controls intake. For meats, traditional Italian salami is a quality choice. Macadamia nuts are particularly high in calories, making them ideal for those needing to gain weight but should be consumed in moderation otherwise.

• Look for nuts in their shells to moderate consumption effectively.
• Macadamia nuts are calorie-dense, so they should be consumed in measured amounts.

Costco provides excellent options for cold-pressed organic oils. When buying olive oil, avoid large plastic bottles that can lead to faster rancidity. Instead, opt for products in smaller glass bottles that are genuine in origin, such as those labeled from Italy or Spain.

• Select cold-pressed, organic oils in small glass containers to ensure quality.
• Avoid purchasing oils stored in large plastic jugs to prevent spoilage.

Shopping at Costco offers many health-conscious options if approached with an informed eye. Always read labels carefully and prefer products with higher nutritional value while avoiding those with harmful additives. This approach empowers you to make smarter decisions for a healthier lifestyle.
