The gut and hormones.
Hormones are typically produced by the endocrine system, which includes the following group of glands and the pancreas: pituitary, pineal, thymus, thyroid, and adrenal.
Your gut microbiome also produces hormones, and in addition, sends signals to the glands in your body that dictate how much of each specific hormone we release.
These include your thyroid hormones (more below), estrogen, serotonin, and more.
Gut dysbiosis (an imbalance of good and bad bacteria) can lower the levels of thyroid hormones T3 and T4, which can lead to what's called hypothyroidism (where your thyroid gland doesn't produce enough hormones). Symptoms include "tiredness, weight gain, dry skin, cold intolerance, constipation, muscle weakness, puffiness around the eyes, hoarse voice, and poor memory.". (study)
So much like our immune system, that ecosystem of microbes in your gut are affecting our hormones. Who'd have thought what many see as just our "stomach" had such a widespread influence...
The gut and the immune system.
A whopping 70-80% of your immune system resides in the gut, and the gut microbiome and the immune system work in harmony with one another.
The gut microbes help to regulate your immune system, and your immune system helps your body form a healthy balance of microbes. “What’s present in the gut determines what education immune cells get." - David Herber, MD, PhD, professor at UCLA Health.
So to summarise, your gut health plays an important role in your immune system.
Another angle to consider is the immune response caused by damage to the lining of your gut. This "breaking of the gut wall" is otherwise called leaky gut, or increased intestinal permeability – which is where holes and cracks form in the gut lining and things seep through that shouldn’t.
What breaks through is called bacterial endotoxin, and this activates the immune system and results in inflammation.
I hope this gives you context on how important maintaining your gut health is to not just the way your stomach feels and how you digest foods, but all corners of your health and wellbeing - including your immune system.
A gut-healthy holiday season.
The holiday season can be the hardest time of year to manage your gut health, I've been there myself with IBS...
But it doesn't have to be!
Here are my top 10 tips for keeping your gut healthy this holiday season:
1. Make gut-friendly swaps. Many of the foods found in a classic Christmas meal are perfectly good for your gut, including carrots, brussels sprouts, potatoes, and more. Refined foods and desserts are where the opportunities for swaps can be found! Instead of indulging in regular chocolate, try switching it for dark!
If you're looking to get into the kitchen and bake, search for some refined/sugar-free recipes - trust me, there are plenty out there! As always, trust your intuition, find the next best, and don't let the situation over-ride you with stress.
2. If you're suffering from a gut issue, as you'll have heard from me by now, cutting out alcohol is my first recommendation. If you are looking to drink alcohol, however, these are my recommendations: red w**e, dry white w**e, c***r, and spirits in their purest form (vodka, gin, wh**ky, tequila, etc.). B**r, flavoured spirits, and liqueurs fall on the "no-go" side for me.
3. Stay hydrated. What it says on the tin... don't forget to get some water down you in the midst of all the chaos!
4. Improve digestion and avoid flare-ups. Supplements like digestive enzymes (which can come in natural forms), apple c***r vinegar, ginger, turmeric, and similar blends can be taken before meals. If you suffer from a flare-up, my go-to's are mint and fennel tea, lemon and ginger tea, peppermint oil, cayenne pepper and turmeric (cooked into meals), cucumber, and yogurt.
5. Stay active! Although much of the festive period is spent static, try to get active whether that be yourself or with your friends and family. Go for a walk, continue exercising on the surrounding days, and start the day with a good stretch and some movement.
6. Relax. Do not, I repeat... do not let the stress of managing your gut over-ride the festive period. Sometimes you'll have to accept the "next best", and others you might deviate from what you otherwise know to be "good for your gut".
That's okay, all is not lost. If you decide to consume something and riddle yourself with guilt, it's a lose-lose. If you're going to consume it, enjoy the moment, let it satisfy you, and soldier on!
7. Plan ahead. Preparation is everything! For all of the tips listed here, a level of planning is required to either stock up or carve out some time to support your gut. Don't wait until you're caught on the back foot. Make a plan so that you can kick back and enjoy yourself.
8. Practice moderation! Something that I want you to consider; going overboard with the festivities isn't going to make your time more enjoyable! This is for two reasons... guilt (mind) and discomfort (body). If you practice moderation and enjoy yourself without setting yourself back.
9. Continue fasting. Fast in the early hours of the day and your gut will thank you for it. Your gut might take a beating from the types of food you're eating or the quantities that you're eating them. Give your body time to digest, process, and tidy up after itself in the morning, ready for the day's festivities.
10. Get back on track the moment that it's all over. No matter what happens, wipe the slate clean and start fresh when the dust settles... hopefully with a smile on your face.
