I spoke with Amelie Becher from Sanctuary Safe Spaces about what I've learned from being chronically ill and what I would pass on to others that need advice.

Nutrition - what do I eat?!
It’s the million-dollar question isn’t it? What to eat to optimize your health and wellbeing. This is especially important when you have some health challenges - either acute infection or chronic illness. There are so many schools of thought out there, and obviously everybody is different so you need to find out what works best for you, but here are some of the basics that I think are relevant for the majority of people...

So you’re chronically ill and feeling fatigued and unwell most days. You’ve either read or been told by a practitioner that you need to make significant diet and lifestyle change in order to improve your health, but how are you supposed to make these changes when you can hardly get out of bed? Bit of a catch 22 right?

This conundrum is one of my clients’ biggest gripes, so as a practitioner I’m always looking for ways to help out and provide guidance around the day-to-day tasks that suck energy and prevent clients from sticking to the therapeutic plan. Check out this blog post for my top three tips.

When it comes to biotoxin exposure, we need to break the cycle of enterohepatic recirculation and systemic absorption of toxins. Enterohepatic circulation is a critical system of the body that governs the progression of bile from the liver, through the gallbladder, into the small intestine and back again to the liver. Almost all bile is naturally recirculated in this manner, so unless there are specific insoluble fibres and binders present in the GI tract, they will be reabsorbed by the hepatic portal vein and continue to put a strain on the detox organs.

If the GI tract is permeable (AKA leaky gut), toxins can also leak into the blood stream through lack of tight junction integrity. A high insoluble fibre diet can be incredibly helpful, but unfortunately many biotoxins like those produced by mould are not so easy to bind and need to be specifically targeted with certain binders.
Here is a table summarising the best binders to use for each specific mycotoxin that may show up on your urine analysis. Credit goes to Joe Mather, Neil Nathan, Jill Crista and Beth O'Hara for putting this information together.
