The most common keto foods that people are allergic to are dairy, eggs, and nuts.
If you are allergic or intolerant to dairy, use these dairy alternatives:
- Replace Milk with Coconut Milk. In recipes, you can substitute coconut milk in for regular milk in a 1 to 1 ratio.
- Replace Heavy Cream with Coconut Cream. You may have to blend in a bit of water or skim some water out of the container depending on the creaminess of the coconut cream.
- Instead of Butter use Coconut Oil or Vegan Butter. Coconut oil has a slightly lower melting point than butter and the same smoke point as butter, which makes it a good butter replacement. If you are not a fan of the flavor of coconut oil, look for vegan butter in your local health food store. Make sure the vegan butter doesn’t contain any hydrogenated oils because these oils increase the risk of heart disease tremendously.
- Replace Dairy-Based Cheese with Nut-Based Cheese. There are plenty of vegan cheeses on the market right now. If you want to avoid soy (for the reasons we will discover later), then you can find coconut, cashew, and other tree-nut-based cheeses. My personal favorite vegan cheese-making companies are Treeline and Miyoko’s Kitchen. Their cheeses are some of the best I’ve ever tasted. In fact, many people think that they are better than traditional dairy cheese. If Treeline or Miyoko’s Kitchen doesn’t have the cheese you are looking for, then try Follow Your Heart’s vegan cheese. Follow Your Heart is another company that makes almost every type of vegan cheese you could ever want.
- Instead of Cream Cheese have Nut-Based Soft Cheese. Treeline makes a cashew-based soft cheese that is delicious and savory, and it has almost the same texture as cream cheese. You can also make some creamy cashew cheese on your own with this recipe.
- Replace Yogurt and Sour Cream with Nut-Based Yogurt. At your local health food market, you will probably be able to find plain almond, cashew, or coconut milk yogurt. Just make sure it has no added sugars or hidden carbohydrates.

If you are allergic to eggs, here’s what you can use instead:
- Flax Seeds. Finely ground flax makes an excellent binder. It has a nutty flavor that works best in recipes for almond or coconut flour baked goods and pancakes. Use one tablespoon of ground flax seeds and three tablespoons of water to replace one egg.
- Silken Tofu. Silken tofu is a softer, silkier form of tofu that makes a good egg and dairy replacement. It is relatively flavorless but it can make baked goods dense, so it’s best used in brownies and some keto quick breads and cakes. Use 1/4 cup of puréed silken tofu for 1 egg.
- Baking Soda and Vinegar. This is a decent egg substitute for fluffier baked goods. Use one teaspoon of baking soda mixed with one tablespoon of white vinegar for one egg.
- The Vegg. The Vegg is a 100% plant-based egg company. By using only natural ingredients, The Vegg has created products that simulate the taste, texture, and function of egg for use in your favorite dishes, all for about the same cost as real eggs.
- Follow Your Heart’s VeganEgg. Follow Your Heart is another plant-based company that makes vegan alternatives of everything from cheese to mayonnaise. They even make vegan eggs! Their VeganEgg is advertised as a vegan whole egg replacement that has the taste and texture of real eggs. You can use it to bake keto-friendly cookies, muffins, and cakes. The VeganEgg can also be used to cook up fluffy scrambled eggs and omelets as well.
The only problem with these egg replacements is that they don’t contain as much fat or protein as a whole egg, so make sure you are making up for this by having plenty of fatty meats, cheese, and plant-based fats and protein (you can learn more about plant-based keto nutrition by clicking here).
If you are allergic to nuts, here are some keto-friendly suggestions:
- Use seed based flour instead of nut-based flour. The simplest keto flour alternative you can use is Sunflower Seed Meal or Pumpkin Seed Meal. All you have to do with these alternatives is replace almond flour/meal with the same amount of sunflower seed or pumpkin seed meal. To learn more about these keto flours, click here.
- Snack on pumpkin seeds and sunflower seeds instead of nuts. Make sure you track the carb and calorie content of the seeds you are eating because they are higher in calories and net carbs than you may think.
- Use seed butter instead of nut butter. There are a handful of seed butter products on the market now. One of the most popular is sunflower seed butter. Just make sure you purchase the seed butters that have no added sugars and track the carb and calorie content of the seed butter product you use.
For those that have food sensitivities, we have some recommendations as well. The two main keto-friendly ingredients that people have a sensitivity to are nightshades and gluten.
Although you probably won’t encounter gluten while you are on the keto diet, make sure you read your labels carefully. Some keto-friendly products (e.g., keto baked goods and soy sauce) do have gluten in them.
Whether you are gluten-free or not, it is best to make most of your food at home using keto recipes and have the rest of your calories from minimally processed snacks like nuts and cheese.
Avoiding nightshade vegetables is a bit more difficult on the ketogenic diet because many keto recipes call for them. If you are sensitive to nightshades, you can either skip those recipes or use some of these substitutions:
- For Tomatoes — In certain dishes, strawberries or strawberry sauce can swap the acidic, slightly sweet profile of tomatoes. Pumpkin and squash-based sauce can replace tomato sauce for pasta-based dishes.
- For Bell Peppers — Zucchini, celery, and cucumbers can sub in for the crispy deliciousness that bell peppers provide in some dishes. Radishes, when used in cooked dishes, can sub in that peppery flavor that red and green bell peppers are known for.
- For Chili and Cayenne Pepper — Black and white pepper come from a different plant and aren’t nightshades. Use these, along with turmeric, cumin, cloves, and ginger, to add a kick to dishes that you want to keep nightshade-free. If you need to replace nightshade-based sauces, you can try fish sauce, coconut aminos, oyster sauce, or Worcestershire sauce.
- For Eggplant — Portobello mushroom caps can substitute for eggplants in baked dishes. For keto eggplant noodle recipes, try using zucchini noodles or shirataki noodles instead.
