[CN: this post discusses nutrition and medical diets]
This post is part of a continuing series on eating with MCAS, and specifically the interactions between the immune system, the gut microbiome, and plant defenses (aka plant secondary metabolites, a type of phytochemical).
I’m working on more posts that have a lot of citations and explain some of the science behind why I think that the inflammatory potential of plants isn’t dependent on what plant you’re eating.
Instead, I believe it’s a combination of both:
- how the plant is prepared (including growth and storage along the supply chain)
- if your particular gut microbiome has the right combination of microbes to digest the plant compounds our bodies can’t (eg fiber, oxalates, phytase, etc). Different microbes help digest different things.
Unfortunately, writing takes energy and I find looking up citations especially fatiguing. (This is unfair because it literally uses to be my job when I was briefly a research assistant in academia, specifically in history which is all about citations.)
So this post is more a list of things specific ways of preparing plants that have worked for me, with less of the explanation of how I think it works. I’m saving that info for later posts.
Every body is different, and these methods may not work for you. I would encourage you to discuss them with a registered dietitian/nutritionist if you have access to one, and/or other members of your medical team.
Step one: plants that are more forgiving
As I mentioned above, any plant has the potential to be inflammatory (because all plants need inflammatory compounds to defend themselves from herbivores).
If you think of plant defenses sort of like a bee sting, I find these plants more like a carpenter bee than a wasp or even a honeybee.
This is a list of produce that tends to be easier to prepare. These are the plants I was typically able to digest when nothing else was acceptable to my body.
As a key point, if you haven’t been able to eat much produce for awhile, eating these plants may help regenerate the parts of your microbiome that digest plants. That means it will be better equipped to digest more types of plants in the future.
Please also note that it’s better to increase your fiber intake slowly to avoid digestive issues. (This is true of anyone, but especially people with MCAS and/or dysbiosis, and for anyone who hasn’t eaten many plants in awhile).
Also please note that the specific preparation methods are important. Additionally, I typically have more luck with fresh local produce versus something pre-cut or frozen. Love to have conflicting access needs with myself.
I understand that these are not necessarily accessible options for everyone (including myself). If you’re not able to get local produce, I have had luck starting with the “happiest” looking produce I can find. (I am sorry, I do not have a solution here for food apartheid, and I understand that some of these recommendations may simply not be an option for everyone.)
I unfortunately also do not have an affordable solution for not being able to chop vegetables, which is something that makes me very nervous because I know that is an ability I currently have that is temporary.
At some point I’m hoping to also write about some of the cooking/prep methods I use to help make cooking more accessible. But I have yet to find a solution to cooking while bedbound (other than hiring someone, which costs money many of us simply do not have).
If you find yourself experiencing a lot of bloating and upper gastric pain, you may want to ask your doctor about SIBO and other types of intestinal overgrowth. It’s possible you will need to treat the intestinal overgrowth before eating a lot of fiber.
Root vegetables
Peel your root vegetables. Yes, a lot of the nutrients are in the peel (and you can save it to make broth!). But a lot of the plant defenses are centered in the peel, too. After all, it’s the first thing herbivores typically bite into.
I’m specifically talking here about tubers that are basically where plants store extra complex carbohydrates and high in soluble fiber.
Note that certain cooking methods can break down the complex carbohydrates too much, so you get a higher glycemic load and less food for your microbiome.
Additionally, certain cooking methods (eg grilling/roasting at high temperatures) can reduce the colorful antioxidants that your body probably needs from dealing with so much inflammation.
Eating a wider variety of colorful tubers can provide your body with different antioxidants. Heirloom vegetables are your friends (if you can find them).
- Sweet potatoes (any color)
- Beets (especially red ones)
- Heirloom purple or blue potatoes
- Carrots, especially rainbow carrots
- Sun chokes (aka Jerusalem artichokes)
- Fennel root
- Jicama (note: peel with gloves away from food preparation surfaces such as cutting boards, and discard the skin as it is toxic)
Turnips, rutabagas, and onions in my experience tend to be more finicky about how they are prepared. (That is, tubers from the Brassica or Allium family)
I find that these are the cooking methods that work best for me:
Prep:
Peel and chop vegetables.
May reserve peels in a bag in the freezer for broth (recommended).
If you need to prep them ahead, then freeze raw prepped root vegetables in a zip lock or other freezer safe container and cook from frozen. (If you’re using a plastic container, then soak it in water for about 20 minutes to loosen the vegetables so you can remove them.)
Instant pot:
Place chopped root vegetables in instant pot and cover with water or broth.
Secure lid and set to high pressure cook for zero minutes. (Note: this just brings the water up to a high temperature and then lets it depressurize.)
Natural pressure release. Note that sweet potatoes and potatoes may dissolve using this method. I typically cook meat on the stove or in the oven, then add it into the vegetable medley.
May also finish them with dried herbs, turmeric, sumac berry powder, or sea salt. Note remove from heat immediately after incorporating herbs or sumac.
You can also puree the vegetables and broth for a cream of vegetable soup. Just add the cream (or coconut milk, etc) directly before serving so it doesn’t curdle. I typically freeze cubes of coconut milk in an ice cube tray, and then add them to my soup as I’m reheating it. Note that pureeing or mashing the vegetables will increase the glycemic index of your meal.
Sheet pan method:
I know everyone loves roasted root vegetables these days with a little bit of browning. My body does not like too much browning/char. So I’ve come up with an alternative method that is still relatively easy.
Preheat oven to 275F. Coat stainless steel pan or Pyrex roasting dish with oil with a high smoke point (I use expeller pressed canola oil, YMMV). If using frozen vegetables, you can cook directly from frozen.
Spread vegetables on roasting trays leaving room between them for steam to escape. Steam them in the oven for 10-20 minutes (longer if cooking from frozen) until most of the water has evaporated, and you can easily poke them with a fork.
If desired, coat with oil and a little salt. Increase temperature to 375F, and roast for 3-5 minutes (just until the vegetables start to become aromatic, but stop before much browning takes place).
If desired, coat with dried herbs, lemon juice, sumac berry powder, ground turmeric and/or more sea salt.
Note: for red/purple/blue tubers, avoid the second higher temperature cook as it can degrade the anti-oxidants. Adding turmeric powder before cooking at low temperature (or sumac berry powder afterwards) can help stabilize/brighten these colorful anti-oxidants.
If you find that roasted vegetables provoke a reactive hypoglycemia flare, then you may need to cook them til they are just fork tender and refrigerate (or freeze and defrost) to avoid that. This cooking process increases the amount of resistant starch, which means a lower glycemic load and more food for your microbiome.If you have a condition such as diabetes, these starchy vegetables may aggravate your condition. I would suggest consulting with your doctor, a nutritionist, and looking for recipes from a reputable diabetes organization.
Summer and Winter Squash
Squash (Cucurbitae) were originally cultivated by Indigenous people in what is currently known as the Americas, specifically Mexico and Central America. There are now many varieties cultivated around the world, so if you’re not a fan of zucchini, you might try experimenting with different kinds of squash.
Prepping your squash:
Again, I would recommend peeling even summer squash as you first introduce it, as I find the peel can be harder to digest if you haven’t eaten squash in awhile. Over time, you may want to try reintroducing it, as many of the anti-oxidants and micronutrients in summer squash are found in the skin.
Winter squash generally have a tougher peel; whether it’s eaten depends on the specific variety. Again, I had better luck introducing the peel slowly
Winter squash can be tough to peel, especially when they have ridges (such as acorn squash). Butternut squash tend to be the easiest winter squash to peel, in my experience. I would also include ridge gourds used in Indian cooking in the category of “squash to always peel.”
For winter squash, you will also need to remove the seeds. You can scoop these and the stringy bits out with a spoon. If someone in your household is planning to eat the seeds, then the easiest way to separate them is actually picking them out from the strings with your fingers, and then removing the strings with a spoon.
It is easier to roast a deseeded winter squash and then remove the peel. This is probably ok as long as all of the seeds are removed, but I haven’t experimented with it much during my severe food intolerance days.
Cube, slice, dice, or chop squash to your desired size. Smaller pieces will cook more quickly and dissolve more easily. Larger pieces will take longer to cook, and take longer to dissolve.
You can freeze your prepped squash here to use it for later. Just bear in mind that you may need to take steps to remove excess water when you defrost it, and it may change the texture slightly.
Avoiding soggy squash:
Much of the fiber in squash is soluble fiber. This means it dissolves in water. If you take your fresh squash and add it to a soup or pot of cooking water at the same time as sturdy root vegetables like carrots, then you risk it dissolving almost completely.
If that is not the texture you are going for, one way you can combat this problem by cooking your squash with oil before adding it to any liquids. The layer of oil forms a barrier between the soluble fiber and your soup of the day.
Defrosting squash:
Frozen squash already has excess liquid left over from the freezing process. So you will need to extract some of the liquid before cooking it in oil.
A few methods for defrosting squash, which can each transition fairly seamlessly to cooking your squash with oil:
- Put squash in a microwave safe container and defrost for 30 second intervals just until it’s no longer frosty. (If you make a note of the amount and time, you can reuse those settings on your next batch.) Note: this method works best for winter squash and other more sturdy squash.
- Preheat oven to 290F (265F for convection). Grease a sheet pan or another oven safe container with low sides. When oven is heated, place squash on sheet pan with plenty of space between them and heat in the oven for around 10 minutes (depending on the size of the squash and your oven), or until you can just puncture the squash with a fork.
- Heat a wok over medium low heat. Place squash inside wok. Do not add any extra water! Cover and heat until steam starts to coat the inside of the lid. Then remove lid, and stir as excess water evaporates.
- This is my least favorite flavor wise, but most favorite in terms of ease and bulking up a meal. Prepare a soup or stew of your choice. After it’s done, leave it at an extremely gentle simmer. Add frozen squash at the end and cover with a lid, allowing it to cook in the broth for around 3 minutes or until desired texture. This works better with squash that is not zucchini. This method will preserve more fiber than other methods listed.
Pro tip: you can speed up water extraction for any of these methods by adding a dash of salt. To preserve anti-oxidants, you can also include a pinch of turmeric.
A collander and paper towels can also help with removing excess water. For recipes where you want truly dry squash (such as fritters), you can physically squeeze the water out of the squash.
Cooking your squash
There are obviously many ways you can cook squash, from zucchini bread to fritters to curry. These are just some suggestions to get you started.
As mentioned above, many of these techniques flow naturally from the defrosting methods mentioned above.
- Oven: cook at lower temperature (above 275F) until you can just start to use a fork to pierce the squash. Remove squash from oven and increase the temperature to 425F (400F convection/toaster oven). Meanwhile, drizzle or brush a small amount of oil over the squash. Return to oven, and bake until it smells fragrant and the edges just start to brown. Remove from oven, and top with ground spices/herbs (if desired) or seasonings of your choice. Or allow to cool and top with fresh herbs.
- Stove top (saute-steam): heat wok over medium and add oil. Add squash and fry until just fork tender (about 3 minutes) with seasonings of your choice. Add salt and ground turmeric, reduce heat, and cover. Cook on low heat for around 20 minutes, allowing the squash to steam in its own juices. (Much appreciation and credit to Bong Eats for sharing this Bengali technique for cooking mixed vegetables.)
- Stove top (steam-saute): Heat wok over medium low heat and add squash and a small amount of water. (If using frozen, omit water.) Cover, and allow squash to steam until the color begins to brighten (1-3 minutes). Remove lid and stir squash, allowing water to evaporate. Add oil, increase heat to medium, and saute squash with oil and aromatics of your choice until desired crispness. (I learned about this technique from How to Cook without a Book, which attributes the technique to East Asian stir fry methods. I’m sure there’s a more precise culinary source, but I am not sure what it is.)
Ideas for flavoring your squash:
What flavoring or seasonings your body tolerates can vary greatly with MCAS. Here are some very general ideas for inspiration:
- Fresh or dried herbs
- Many cultures dry a sour fruit and grind it into a powder (eg sumac berry powder in Middle Eastern cooking; amchoor powder in Desi cooking); I found that I tolerated this better than citrus for a long time.
- Any spices that you tolerate (for example: cumin, coriander, etc)
- Add grated ginger or any aromatics you tolerate; this is especially delicious when using sauted in oil on stove top.
- Make a bastardized stir fry sauce out of fat, sugar, salt and acid (eg maple syrup, coconut oil, salt and rice vinegar, which is typically low histamine.)
- Coconut aminos
- Sea salt and the natural flavor of the vegetables
Disclaimers
