This topic is about someone who has suddenly developed an intolerance to homemade French fries after a year of eating them without any issues. They experience stomach pain and a feeling of partial blockage when eating fries, although other potato dishes like mashed, hash browns, and baked potatoes are still fine. They are curious if others have experienced a similar late-onset intolerance to a food that was previously safe.

Here are some helpful insights and advice:

1. It's common for reactions to foods to be inconsistent. One day potatoes might be fine, and the next they might cause issues. Keeping a food diary can help you track what works and what doesn't.

2. Intolerances can develop over time. Pay attention to how often and how much you eat certain foods. This can help prevent discomfort, especially if you're dehydrated.

3. Try eating fries with other foods, like a burger, and chew everything thoroughly. Avoid eating fries alone and keep portions small.

4. Overeating fries, especially thicker styles, can lead to problems. Moderating the amount you eat can help reduce the risk.

5. Balance foods that tend to bind, like fries, with those that help maintain regularity.

6. For some, the issue might be with fried or high-starch foods in general, which can cause gas and discomfort. Reducing these foods and limiting starches, and possibly dairy, might help.

7. If changes in food tolerance persist or worsen, it's a good idea to consult with a stoma therapy nurse or healthcare professional.
