Always avoid: All grilled chicken, salad dressings, onions, chili, and wheat buns

How to Order

When ordering at Wendy’s on a low FODMAP diet:

1. Start with a baked potato - Your best bet for a satisfying, safe meal
2. Or choose bunless burgers - Plain beef patties are safe
3. Skip ALL chicken - Even grilled chicken contains garlic and onion marinade
4. Add safe toppings - Cheese, bacon, lettuce, tomato
5. Avoid dressings - Bring your own or use plain oil
6. No onions - Always specify when ordering

The Baked Potato Advantage

Why Wendy’s baked potatoes are perfect for low FODMAP:

Wendy’s is one of the few fast-food chains offering baked potatoes, making it an excellent choice for low FODMAP dieters.

Safe baked potato options:

Plain Baked Potato

• Just potato, no toppings
• Completely safe
• Very filling
• Good source of potassium and fiber

Cheese Baked Potato

• Baked potato with cheddar cheese
• Cheese is low FODMAP in typical amounts
• Great for added protein and fat
• Very satisfying meal

Bacon Cheese Baked Potato

• Adds bacon for extra protein
• Verify bacon doesn’t have problematic seasonings
• One of the best low FODMAP fast food meals available

AVOID: Broccoli Cheese Baked Potato

• While 1/2 cup broccoli is low FODMAP
• The serving on this potato often exceeds that amount
• The cheese sauce may contain additional ingredients
• Better to stick with plain cheese version

The Chicken Problem

Important: All Wendy’s chicken is marinated with garlic and onion.

Why you can’t have chicken at Wendy’s:

Even though many older low FODMAP guides suggested Wendy’s grilled chicken, corporate communications have confirmed:

• The fajita chicken used in salads contains garlic and onion
• Grilled chicken has garlic and onion in the marinade
• These marinades are not removable

Avoid ALL chicken items:

• Grilled chicken sandwiches
• Crispy chicken (also has wheat breading)
• Chicken nuggets (wheat coating)
• All salads with chicken
• Fajita chicken
• Chicken wraps

What about the sausage patty? Natural flavors in the sausage patty are unclear - Wendy’s did not answer questions about these ingredients. Proceed with extreme caution or avoid entirely.

Bunless Burger Strategy

Wendy’s beef patties are your safe protein option:

What to order:

• Hamburger or cheeseburger - no bun
• Single, double, or triple patty (based on hunger)
• Add lettuce and tomato
• Add bacon if desired
• Add cheese if you tolerate dairy

What to skip:

• The bun (wheat/fructans)
• Onions (always specify “no onions”)
• Special sauces (likely contain garlic/onion)
• Ketchup (high in fructans, though small amounts may be OK)

How to order:

“Can I get a hamburger with cheese and bacon, but without the bun? Just the patty with lettuce and tomato, no onions. Can you put it in a container?”

Most Wendy’s locations will accommodate this request in a salad container or burger container.

French Fries: Generally Safe

Good news about Wendy’s fries:

• Fried in vegetable oil
• Should be safe for most low FODMAP dieters
• No wheat derivatives (unlike McDonald’s)

One caution:

• Verify they’re not cooked in the same fryer as onion rings
• Cross-contamination could be an issue if you’re very sensitive
• Ask staff about their frying procedures

Salad Options (With Major Modifications)

Wendy’s salads are beautiful but problematic for low FODMAP dieters:

Why the salads don’t work:

• All include grilled chicken with garlic and onion marinade
• Chicken is mixed throughout, hard to pick out
• All dressings contain garlic, onion, or fructose

Problem salads:

• Parmesan Caesar Salad (chicken with garlic/onion)
• Southwest Avocado Salad (chicken, beans, problematic dressing)
• Apple Pecan Salad (apples are high FODMAP, chicken issue)

Possible workaround: Order a side salad (just greens) and:

• Bring your own low FODMAP dressing
• Add a plain beef patty for protein
• Skip croutons
• Keep it simple with lettuce and tomatoes

What About Ketchup?

The ketchup controversy:

Ketchup is high in oligos-fructans (a FODMAP type), which can be problematic.

Your options:

1. Skip it entirely - Safest option
2. Use sparingly - Very small amounts might be tolerated
3. Bring your own - Low FODMAP ketchup from home
4. Use mustard instead - Usually safer (check ingredients)

Staff Communication Tips

Wendy’s staff are generally helpful with modifications:

For baked potatoes:

“Can I get a baked potato with just cheese and bacon? No broccoli, no other toppings.”

For burgers:

“I’d like a cheeseburger with bacon, but no bun and no onions. Can you put it in a container with lettuce and tomato?”

For clarity on ingredients:

“I have a digestive condition and need to avoid garlic and onion. Can you confirm the beef patty doesn’t have any seasonings besides salt and pepper?”

Beverage Choices

Safe beverages:

• Water (always the safest)
• Unsweetened iced tea (verify no added flavors)
• Some diet sodas (check ingredients)
• Coffee, black (no milk or cream if lactose intolerant)

Proceed with caution:

• Regular sodas (high fructose corn syrup, carbonation can cause bloating)
• Lemonade (check for high fructose ingredients)

Avoid:

• Frosty (dairy-based, likely high FODMAP)
• Milkshakes
• Flavored iced coffees (may contain milk and sweeteners)

Breakfast at Wendy’s

Wendy’s breakfast menu is limited in some locations. If available:

Potentially safe options:

• Plain eggs (if you can order them)
• Sausage (verify ingredients - natural flavors are unclear)
• Avoid all breakfast sandwiches (wheat buns)

Better strategy: If you need breakfast, Wendy’s isn’t your best option. Consider McDonald’s for plain eggs and breakfast items.

Making It More Satisfying

Without the bun and chicken options, here’s how to make Wendy’s more satisfying:

Add extra protein:

• Double or triple beef patties
• Add bacon to everything
• Get bacon cheese baked potato instead of plain

Add healthy fats:

• Cheese on burgers and potatoes
• Bacon
• Bring your own avocado (small amount is low FODMAP)

Add volume:

• Large baked potato
• Extra side salad
• French fries
• Bring your own low FODMAP crackers or chips

The Value Menu Strategy

Wendy’s value menu can help you eat low FODMAP on a budget:

Budget-friendly options:

• Jr. Hamburger (no bun) - cheap protein
• Value fries
• Side salad
• Plain baked potato (not always on value menu but affordable)

Money-saving tip: Order multiple Jr. burgers without buns for protein at a lower cost than larger burgers.

Allergen Menu Notes

Wendy’s provides nutrition and allergen information on their website.

How to access: Visit wendys.com/nutrition-allergens for:

Key allergens at Wendy’s:

• Wheat (buns, breading, croutons)
• Dairy (cheese, Frosty)
• Soy (various items)
• Eggs (some items)

Remember: Allergen menus show top 8 allergens, not FODMAPs. You still need to ask about garlic and onion specifically.

Cross-Contamination Considerations

Potential cross-contamination sources:

• Grills may have residue from garlic/onion seasoned items
• Fryers might be shared with onion rings
• Preparation surfaces might contact problematic ingredients

What to do:

• Ask about cooking procedures if you’re very sensitive
• Request fresh gloves for food prep
• Accept that some cross-contact is inevitable in fast food
• Save Wendy’s for when you can tolerate minor exposure
