Fitness Optimisation

Food Intolerance & Fitness

Whether you are training for an athletic event or just looking to get in shape, diet is an important factor in improving your health and fitness.(1) .

Whilst trying to hit nutritional goals, it makes sense to ensure that the foods and drinks we are consuming are agreeing with us, and not causing us problems!

For example, If you are following a calorie-controlled diet, whilst consuming foods you are intolerant to – feeling bloated and lethargic may have a negative impact on your weight loss progress.

Smartblood Story - Kathryn's Weight Issues.

Kathryn, a keen hill walker, has always had problems with her energy levels, as well as experiencing fluctuations in her weight with no discernible cause.

Recently, one of Kathryn’s friends recommended that she take a Smartblood Food Intolerance Test – this test identified her IgG trigger foods which she replaced with non reactive foods with the help of a Smartblood Nutritional Therapist – now she feels better, and climbs bigger hills!

After taking the test and changing my diet, I noticed a big improvement in my energy levels and weight, as well as less pain from bloating! - Kathryn

Smartblood could help you to identify causes of your joint pain.

Smartblood Laboratories are Food Intolerance Specialists. We provide you with an accurate testing service based upon a 45 year old Laboratory method known as ELISA Plate Testing.

By testing a small sample of your blood, we will show you your IgG reactions to 134 food and drink ingredients – if you test positive to any of them then research shows that it is possible that you have a sensitivity to that food type. By eliminating that food type with the help of one of our nutritional therapists you could take control of your joint pain.

Instant Results Access

At Smartblood, we know how frustrating it can be waiting for a postal copy of your food intolerance test to arrive, especially if you are keen to know what trigger foods could be responsible for how you are feeling.

As soon as full Smartblood programme results have been approved for release by our Laboratory Director your full results report will be sent to you via email. View a summary of all reactive food groups and delve further in with interactive charts for each food or drink section, including one specifically for wheat, gluten, and other grains.

Matt's Food Intolerance to Gluten

Maggie's Story - Food Intolerance and Fatigue

A 2012 study looked at eliminating IgG antibody food reactions from the diet, and it’s effect on body composition and quality of life. 120 subjects over the age of 18 took part in a study, involving elimination of their IgG reactive foods for 90 days. Those who eliminated their IgG reactive foods from their diet experienced reductions in weight, BMI, waist & hip circumference. Subjects also saw improvements in all quality of life measures after 90 days.
