If you have multiple food allergies, one of the best ways to help yourself is to “rotate” your foods, or eat a rotation diet. Four days allow you to keep track of what you are eating to avoid repetition and prevent you from forming new food intolerances

What is a rotation diet?

A rotation diet is a system of controlling food allergies by eating biologically related foods on the same day and then waiting at least four days before eating them again. Such a diet can help those with food allergies in several ways and may help prevent the development of allergies to new foods.

Why rotate your foods?

1. We are biologically designed to rotate foods.

Man is meant to eat with the seasons. We are not designed to eat avocado every single day, because nature does not allow for it. In nature (or even 100-150 years ago) we ate what was local and available.

2. Rotation allows for more nutrient diversity.

If we eat avocado as our main source of fat every day, we’re missing out on all of the healthy fats in olive oil, coconut, and beef tallow. Different foods come with different nutrients and we need variety for vibrancy!

3. Eating the same foods constantly can cause food intolerances and impede gut healing

Any food, if eaten repetitively, can cause food allergies especially if we have gut issues.
Why? Like we stated above, our bodies aren’t designed to eat the same thing over and over again. And if we have permeable intestines and are eating avocado daily, our immune system is reacting to the avocado over, and over, and over again. Eventually it becomes too much.
Surely, the goal is to heal the gut. However, an important piece of gut healing is to remove inflammation, and stopping new intolerances from forming. Thus, a rotation diet can be an amazing strategy within a gut healing template.

What’s New

Version 1.0.16

In this version we fixed a bug that prevented users from uploading their custom food pictures. We also added a new button in the Configuration screen to make it easier to add custom food.

I was really excited to find this app but I am already having issues with set up. It will not let me add foods in the new group I made for fats. So far that is as far as I have gotten. Haven’t put it to use yet to see if it is more helpful than the schedule I am currently using. I was hoping for more food options. The app looks like it has potential and would be a great resource for those of us that need to follow a rotation diet for gut health.

Glad This App Is Available

Hello. I am the first person to review this app. I usually don’t post reviews, but I want the developer to know I appreciate that this app is available. I like the simple design and can see how it will help me rotate foods and will also help me to think of foods I usually wouldn’t consider. At the moment it seems somewhat limited, but I think that is because it is new. In terms of improvements, I would like to see an option to add in foods that are not included in the current selection, such as Honeydew or Cantaloupe or different varieties of fish that are local to me. I would also like to see nuts and seeds added to the app. I’m looking forward to seeing how the app develops over time. Thank you for creating it.

Hello Futurepetvet,

Thank you so much for your words. You can now add your own custom foods and categories in the app. We hope you like it!

Thanks again for your review!

Yeah!!!!! Just what I need!!!

This app is amazing!!! I’ve been struggling with food sensitivities in and off for over 15 years and this is just what I need to avoid future sensitivities. As a feature request... can you add “fats/oils”? I’m sensitive to safflower, olive, coconut, and soybean oils so that doesn’t leave many options and I don’t want to create problems with the few remaining options like avocado, almond, apricot seed, sunflower, canola! Fingers crossed!

Hi! We are so glad you liked it :) We included a new feature to add your own ingredients to the app although we didn't give it much visibility. If you try searching for a new food and it's not there, you'll see a button to add your own. Let us know if that works for you.
