Summary
The mind and the body are always inextricably connected.
Here’s the truth: multiple food sensitivities are rarely about the food alone. And if you’re eating in fight-or-flight, you’re physiologically set up to react before the first bite even hits your stomach.
This episode connects gut-immune mechanisms with nervous system reality. Erin walks through what actually drives multiple food sensitivities from the body up and the mind down, and where she gets hot to trot: the expectant state. She explains why fear-based eating can amplify symptoms and how belief alone can shift physiological response.
If you’ve been stuck in restriction cycles or reacting to “everything,” this will help you stabilize instead of spiraling.
In this episode:
- The two vitamins that can REALLY help to stabilize the immune system if we are reacting to a lot of foods
- Dr. Alia Crumb’s milkshake study that proves belief can shift hormone output and hunger signaling
- How overactive dendritic cells act like “Pac-Man” in your small intestine and flag too many foods for destruction
- Erin’s recommended pre-meal practices that can shift Secretory IgA levels and improve tolerance

| 0:00.0 | We also need to look to the mind. We have to look to the thoughts, the beliefs, the emotions, |
| 0:05.4 | the attitudes, and the expectations that you bring to your food. What is your expectant state |
| 0:12.8 | when you sit down to eat food? Are you expecting to react negatively to food? If so, |
| 0:20.2 | you are telling your mind. You are essentially putting a |
| 0:23.5 | placebo effect on your body. You're telling yourself. You are instructing yourselves. You're |
| 0:29.6 | instructing your digestive system in your body to do exactly that. React negatively. |
| 0:35.4 | Welcome to the functional nutrition podcast. Sp it with a K, because we do |
| 0:38.8 | things a little differently around here. I'm your host, Erin Holt, and I've got 15 years of |
| 0:43.0 | clinical experience as a functional nutritionist and mindset coach, creating a new model that I |
| 0:47.8 | call intuitive functional medicine, where we combine root cause medicine with the innate |
| 0:52.3 | intelligence of your body. This is where science |
| 0:55.4 | meets self-trust. Your body already knows how to heal and this show is going to show you how. |
| 1:01.5 | If you're looking for new ways of thinking about your health, be sure to follow and share with |
| 1:05.4 | a friend because you never know whose life you might change. Hello, my people, my health junkies, my wannabe health |
| 1:13.5 | junkies, my practitioners, my people, whoever's out there listening, hello, hello. We've been |
| 1:19.1 | doing some long-ass episodes lately, so I'm going to try to cut her down a little bit. I'm going to |
| 1:23.1 | try to do this in 30 minutes or less. Today we're talking about food sensitivities. So this episode is for |
| 1:29.8 | you if you have a lot of food reactions, food sensitivities. If you've got a friend that deals |
| 1:36.1 | with the same thing, send them this episode because I'm going to be really comprehensive. |
| 1:40.7 | I'm going to attempt to be really comprehensive, but also succinct. So let's see if I can do it. |
| 1:45.1 | This was inspired by a recent live class in FNA, the Functional Nutrition Academy, where we |
| 1:51.9 | discussed how to best support our clients with multiple food reactions, because this is just |
