An Unfortunate and Lengthy Adventure in Misdiagnosis

Crap nutritionists strike again

with 2 comments

GP Wendy Denning and nutritionist Vicki Edgson, stars of Channel Five’s The Diet Doctors Inside And Out, have exclusively teamed up with Now to answer your diet and health questions.

Q I started drinking about a litre of fruit juice a day and eating grapes, pineapples, melons and oranges. But I got painful red cracks on the edge of my mouth. Could this be due to too much citrus fruit in my diet?

Vicki says I’m surprised you haven’t also had extreme bloating and wind! In fact, the only fruit you’re eating that strictly falls under the citrus category is oranges, but the others are highly acidic. Also, a litre of fruit juice every day will cause disruption to your blood sugar levels, causing highs and lows of energy.

May I suggest that you cut back your consumption of fruit to two to three portions a day and don’t have grapes on the same day as melon, as these are both very high in fruit sugars? Don’t get me wrong – fruit’s great, but vegetables should also be making up your five a day. You may also like to include the humble apple, pear and banana in your fruit diet, all of which contain pectin, which helps to remove toxins from the digestive tract, as well as providing fibre. – Now magazine, 23 Aug 2006

Did it not at all strike Vicki Edgson that “painful red cracks on the edge of my mouth” sounds exactly like riboflavin deficiency? Especially in the context of consuming huge amounts of fruit-sugar carbohydrates which are deficient in B vitamins?

True, occasionally the same symptoms can be caused by B6 deficiency (which in this case may be caused by the vast quantities of pyridoxine glycosides this girl must be consuming), or even iron deficiency anaemia, which wouldn’t be surprising as this sounds like it may well be a fruitarian diet.

These symptoms could well be caused by salicylates and polyphenols, but I doubt the great intellects that are Wendy and Vicki have ever heard of salicylate intolerance.

But surely not even considering riboflavin deficiency in the context of “cracks at corners of mouth” is tantamount to negligence?

  1. Umm, I got exactly the same thing immediately after eating fresh pineapple. I don’t have any vitamin deficiencies that I know of, and I don’t really care about preventing it since I know for a fact it was the pineapple that caused it, I just want it to go away!!

  2. I doubt you could get actual cracks at the corners of your mouth *immediately* from eating anything – cracks appear over the course of several days or weeks as the skin fails to renew itself properly. I assume instead that you got a rash or some inflammation around your mouth caused by pineapple? This isn’t very surprising. Pineapple is a pretty reactive food that contains a protease called bromelain which causes irritation. The answer is to not eat it.
