The Hidden Truth of Food Sensitivity and Digestive Health

Roger Deutsch

CEO of Cell Science Systems

It’s estimated that at least 32 million people (and rising) suffer some form of food sensitivity in this country. Typically missing from the conversation surrounding food sensitivities, however, is the link between them and serious diseases.

“Anybody who has a gastrointestinal (GI) issue has a sensitivity to one or more foods,” says Roger Deutsch, CEO of Cell Science Systems and a pioneer of food sensitivity testing.

What you eat

“The gut is where everything starts,” Deutsch says. “The preponderance of what makes us what we are is what we eat. We can even take that a step further—if you’re eating animals that were fed things that are not normal for them, that impact is transmitted into their physiology, and then when you consume them, you’re consuming something which is already adulterated.”

The body’s reaction to what we eat can affect just about every part of us. “Most of your immune system is in your gut,” Deutsch notes, “because the immune system has to keep you safe from things that go in your gut. If something we eat is not appropriate for us, the immune system will reject it. And in the process of rejecting, it will induce an inflammatory response.”

That inflammatory response to food sensitivity can present as gastrointestinal disease which can lead to expensive treatments and even surgeries to remove all or part of the intestines.  Other conditions associated with chronic activation of the innate immune system are eczema, psoriasis, chronic fatigue, cognitive decline, respiratory illness, obesity, metabolic syndrome, thyroid illness, and the list goes on.  But such outcomes can be avoided if we identify the foods that we’re sensitive to and adjust our diet accordingly.


Cell Science System’s Alcat Test can do just that. “We’ve spent many decades developing this technology whereby we measure how your immune system responds to foods and other substances,” explains Deutsch. “It’s a simple blood test whereby we expose the immune system cells that are circulating through your blood to the foods in your diet and determine whether or not the immune system rejects them or accepts them.”  The Alcat Test has been validated at Yale School of Medicine and has been proven to benefit patients with irritable bowel syndrome (IBS). 

By identifying and eliminating foods that cause inflammation, Deutsch believes we can alleviate and even reverse conditions including Crohn’s disease and irritable bowel syndrome.  Following a personalized diet directed by the Alcat Test can also confer benefits to the gut flora which is critical for digestion,” Deutsch explains. “Our guts contain trillions of bacteria that assist in our digestion and other aspects of our health, breaking down foods, training immune cells, and helping to detoxify our bodies.   Consumption of certain modern agricultural products, like herbicides, can have a detrimental effect upon our gut flora.

But eliminating the foods that hurt us can have the opposite effect. “We have seen and documented in studies, benefits to dermatologic problems like eczema, psoriasis, angioedema, and to autoimmune disorders like arthritis, multiple sclerosis, and ulcerative colitis,” notes Deutsch. “We’ve seen a great benefit to people in terms of metabolic function. We see people lose weight if they need to lose weight.  We see those who are malnourished due to poor digestive health and local inflammation, gain weight if they need to gain weight ”

Deutsch says that in addition to being thoughtful about the food choices we make, including choosing cage free poultry, grass fed/finished beef, and fresh and organic produce whenever possible, testing to discover possible food sensitivities or allergies is essential. “Everyone should have these tests done,” he says. “Just about every disease process that we see—including fatalities from COVID-19—are related to underlying inflammatory processes that degrade various organs and tissue. What we eat becomes what we are.”
