Money-Saving Shopping Tips
Eating gluten-free on a budget is achievable with a few smart strategies. Here are some tips to help you save money on your grocery bills:
- Embrace Naturally Gluten-Free Foods: Build your meals around foods that are naturally gluten-free, such as fruits, vegetables, rice, potatoes, corn, beans, lentils, nuts, seeds, eggs, dairy products, and unprocessed meats. These are often more affordable than their specialty gluten-free counterparts.
- Buy in Bulk: Grains like rice and quinoa, as well as dried beans and lentils, are often cheaper when purchased in bulk. Look for these items in the bulk bins at your local grocery store or at wholesale clubs.
- Shop Seasonally and Locally: Fruits and vegetables are typically less expensive when they are in season. Visit local farmers’ markets for fresh, seasonal produce that may be more affordable than what you find at the supermarket.
- Plan Your Meals: This meal plan is a great start. Knowing what you’re going to eat for the week helps you create a focused grocery list and avoid impulse purchases.
- Cook at Home: Restaurant meals and pre-packaged foods are convenient but can be expensive. Cooking at home gives you control over your ingredients and your budget.
- Use Leftovers Wisely: This meal plan is designed to make use of leftovers for lunches, which saves you both time and money.
- Don’t Be Afraid of Frozen: Frozen fruits and vegetables are just as nutritious as fresh and are often more affordable, especially for out-of-season produce.
