Bread/toast contain yeast/gluten/wheat, which all can cause very big problems in those with candida/mercury. In fact, when I used to consume those, I was extremely ill. I gave them and sugar up and after 3 weeks of detox/withdrawal, I made big improvements.

Fungus infections are also a sign of the fungus within. That and bloating are signs of yeast overgrowth yes. That and more! You can add cramps, depression/anxiety, fatigue, insomnia/oversleeping, itching (particularly in certain private areas), coated tongue etc. There are plenty more to add to the list. Candida causes it's own suffering in mercury toxic individuals that can add to, or even surpass the symptoms of mercury.

How do you know you don't have candida at the moment? If you have amalgam toxicity or anything else that challenges/lowers immunity, it is highly likely you will have candida. The body is unable to keep a healthy balance of yeast when it's been unbalanced by mercury and/or other toxins/chemicals/illnesses.

Tests for candida are not usually very reliable. The best test is to simply give up the sugars/gluten/high carbs/yeast/dairy (apart from butter which is the only true safe dairy for candida) foods and go from there and see if things improve. It may take a few weeks. And you may even feel worse temporarily as yeast start to die off.

You can google candida if you want to know more about the symptoms. There are plenty of articles that have them listed. You can also do a symptom check on yourself in doing so.

If you do have candida and it's highly possible, consuming the breads/toast and cheese etc will be causing big problems.

The safe foods for candida are meats (including chicken), eggs, low carbohydrate vegetables, sugar free acidophilus yoghurt (might be ok, but it cantains lactose in the form of galactose, which is still a form of sugar), raw nuts maybe ok (exclude peanuts). Herbal tea is good. Black tea maybe ok, but still has some caffeine. Coffee should be excluded! That has caused me to relapse completely.

Outside of this it becomes a bit risky. Candida can quite happily feed off the sugars in fruit, grain, potatoes/corn/peas/beans etc, milk/cream etc. Cheese is an issue also.
