Why Book Your Immune & Nutrient Profile in London?
By Tharb Faisl
Why a Simple Meal Can Sometimes Turn Dangerous? Headlines about food recalls – like the recent blueberry listeria scare in the UK – are unsettling. But why do some people just get a mild stomach upset while others end up severely ill or even hospitalised?
The answer often hides deeper in your body, in the state of your immune system – and that depends heavily on your nutrient levels.

The Science: How Your Body Actually Fights Off Listeria & Other Bacteria
When you eat something contaminated (like produce with Listeria monocytogenes), your gut’s first line of defence is stomach acid and mucosal barriers. But if bacteria slip through, your body calls in cell-mediated immunity.
That’s driven by:
White blood cells (macrophages & T-cells) that engulf and destroy bacteria.
Zinc, vitamin D & B12, which directly support this cellular response.
A healthy gut lining, which needs folate & other B vitamins to regenerate quickly.
When any of these nutrients run low, your defence falters.

What Deficiencies Make You Most Vulnerable?
| Nutrient | Role in Fighting Infections | Impact if Low |
| Vitamin D | Primes innate immune cells (macrophages, dendritic), promotes antimicrobial peptides. | Slower initial response, higher infection risk. |
| Zinc | Essential for white blood cell activation & cytokine signalling. | More frequent or prolonged infections. |
| Vitamin B12 & Folate | Needed for DNA replication in rapidly dividing immune cells. | Poor antibody production, anaemia weakens body overall. |
| Iron (balanced) | Too low: immune cells starve. Too high: feeds bacteria. | Imbalance worsens infections or leaves cells underpowered. |
Studies show even mild vitamin D deficiency can increase susceptibility to respiratory & gut infections by 40-60%.
Zinc shortage is known to lengthen bacterial gastroenteritis duration.
Could This Be Why You React Worse to Food Poisoning?
Many London professionals eat on the go, skip meals, or rely on coffee — not exactly a recipe for optimal nutrient intake. Combine that with chronic stress (which depletes B vitamins and zinc), and you’re quietly setting up the perfect conditions for a bacterial invader to win.

The Tests That Reveal If You’re at Risk
At Marylebone Diagnostic Centre, we’ve designed comprehensive panels that look beyond simple GP checks.
| Test Profile | What It Tells Us |
| Vitamin D levels | If your innate defences can quickly engage. |
| Zinc (via Mineral Hair or Serum) | Long-term reserves vs immediate levels. |
| B12 & Folate | Needed for new immune cell growth. |
| Ferritin & Iron Panel | Checks balance critical for immune battles. |
| CRP & Full Blood Count (FBC) | Spots subtle infections your GP might overlook. |

Why Not Just Take Supplements?
Because too much of certain nutrients (like zinc or iron) can backfire, disrupting other minerals or even fuelling bacteria. Testing pinpoints exactly what you need, safely.

Real London Example from Our Clinic
“Jason, 36, came in after a nasty bout of gastroenteritis from takeaway chicken. He felt wiped out for weeks. Tests showed low zinc and borderline vitamin D — meaning he was poorly equipped to clear the infection quickly. Within three months of tailored replenishment & small diet changes, his energy, gut and skin all improved dramatically.”
