Food Intolerances to Protein Isolates

Those of use that take Protein Powders after a workout expose ourselves to large quantities of individual proteins. If the powders are tolerated then personal goals are more easily achieved due to the a high bioavailability of the protein molecules. However, if you are intolerant to the protein powder you are using, this can present as a food intolerance.

Manifesting as bloating, Irritable Bowel Syndrome (IBS), weight gain, fatigue, skin problems, migraines or joint pain, even a mild food intolerance to protein powders may have a major impact upon exercise and appearance, as well as a person’s day to day activities. The possibility of a sensitivity to protein types should therefore be high priority for those that take their exercise seriously.

Smartblood Story - Matt's Intolerance to Whey Protein.

Matt is currently studying Maths and Physics at the University of Bristol. Matt has had Eczema all of his life – although steroid creams help during flare-ups, when he stops using the creams, the Eczema returns. 

View Matt’s video story to see how a Smartblood food intolerance test helped Matt identify his trigger foods, one of which was Whey Protein, and how a consultation with a Smartblood Nutritional Therapist helped him switch to Pea Protein Isolate, which helped his skin health.

I've had eczema on my hands for most of my life. I struggled to find out what was causing the problems, even steroid creams didn't really help. The Smartblood Food Intolerance Test found I had reactions to whey protein, gluten & cherries. After cutting them from my diet, my eczema almost completely cleared up within a month. - Matt

Matt's Food Intolerance to Gluten

Maggie's Story - Food Intolerance and Fatigue

The Science behind the story

In a Randomised Controlled Trial Conducted by Atkinson, Sheldon, Shaath et al, a clinically significant improvement in symptomatology was observed in patients eliminating foods to which they were found to exhibit sensitivity, as identified by an ELISA test for the presence of IgG antibodies to these foods - see more details and studies on our scientific studies page.
