The reason we are so sick is because we have turned our diet upside down.

When you understand that disease is actually slow-burn poisoning - it starts to explain everything.

If you need vitamin supplements - it means your small intestine is not absorbing nutrients properly. Why is that? It's because your gut has been damaged - and the most likely culprits are food toxins.

The very first nutrition advice was written by a nineteenth century American scientist, Mr Wilbur Atwater – a pioneer in measuring how the body generates energy from foods. Then the farmers got involved ... then the politicians ...

The protein in diet shakes is milk protein - which is not even available to the human digestive system. But what's worse - these shakes deliver toxins in large amounts.

We reach for the tablets because that is what medicine has taught us . . . but what if we could find the cause?

If probiotics make you feel better - what can you conclude from that? We need to think.

Take care about the rush to plant-based foods like beans, chickpeas and lentils. These contain toxins which cause anxiety and behavioural issues in children.

The small intestine is your body's gatekeeper. It keeps the good things in - and eliminates the unwanted stuff. But when it gets damaged - things go wrong.

If you have anaemia or an iron deficiency - it is because your small intestine is compromised. Why did that happen?

When the patients took food toxins out of their diet (say a dairy-free, gluten-free diet) - their disease markers improved.

They may seem innocent and delicious - but many familiar food choices carry toxins that slowly breed disease.

One major difference is that food allergic reactions are usually immediate … while food intolerance responses can be very slow. But the immune system is involved in both.

There are five types of tests for food intolerance . . .

Food toxins trigger a wide range of symptoms - from skin issues to inflammation to infertility and serious disease. Many of us underestimate the poisoning power of food toxins - eating them many times a day.

How can food intolerance be cured? We need to understand a little bit about how the body works and how the immune system responds to poisons.

An institute is a centre of discovery, research and publishing . . .

Deborah Manners, food intolerance expert is interviewed about the stealthy nature of food toxins and their impact on the body . . . and why gluten intolerance can be tricky to pinpoint.

The Food Intolerance Institute can guarantee results because all our programs are based on tried and proven methods. Thousands of our members have shared their personal stories.

A journal really sorts things out - because it’s so easy to forget what we ate for dinner.

Sometimes ‘life events’ can bring something to the surface. When the immune system is compromised (as when food toxins are present in the body) it can be a tipping point for a new symptom or illness.

It’s easy to get caught up in the one-a-day habit. But what’s really in all those vitamins and supplements? … And could they be doing you harm?

I see people suffering simple food intolerance symptoms all around me - but they don’t seem to understand that there’s such a simple solution.
