“The UK’s Food Inflation Crisis is a Slow-Burn Public Health Emergency” Says Longevity Expert
It has been revealed by Food Foundation that food inflation has risen to 3.7% in the year up to March 2026, with the price of some foods, such as olive oil, more than doubling. Due to this more than half of the households in the UK are sadly cutting back on essential fruit and vegetables in the last month alone, according to the Food Foundation.
According to longevity expert Ralph Montague, author and founder of The Longevity Clinic, and recently featuring in BBC Good Food, cutting fruit and vegetables from diets will trigger a cascade of biological consequences that may take years to show up in NHS statistics. Ralph is calling on health journalists, policymakers and the British public to help educate them on what is actually happening when they cut out essential vitamins, as well as eating a lot worse than they were six months ago.
Ralph comments: “When people cut fruit and vegetables from their diets, they won’t feel the effects straight away, but it will be a gradual depletion of essential vitamins.
Your body will be missing antioxidants and micronutrients that regulate inflammation, support immune function and protect cellular integrity. There is a huge biological cost of dietary downgrading, things we may not necessarily notice on the outside, but are definitely going on inside.
We’re not talking about clinical malnutrition that may show up on blood tests, but you’ll be missing out on essentials to help with your day-to-day functioning, like zinc, magnesium, B vitamins, vitamin C etc.
Each one of these has an absolute critical role in helping the body; whether this is immune regulation, neurological function, supporting cardiovascular health or even the body’s ability to repair any cellular damage.”
When looking at individual systems, Ralph discusses the consequences of lacking on specific nutrients:
Immune Suppression
Ralph says, “Micronutrient deficiencies, particularly in vitamins C, D and zinc, directly impair both innate and adaptive immune responses, increasing susceptibility to infection and slowing recovery. These vitamins are absolutely essential to supporting your immune system.”
Accelerated biological aging
“Ensuring that you’re taking in a good amount of organic foods, protein and good fats ensure that your biological age isn’t increasing years above your actual age.” Ralph tells us. “Sustained oxidative stress shortens telomeres and impairs cellular repair mechanisms, the biological equivalent of aging faster, which can be found in fruits and vegetables.”
Increased systemic inflammation
“Diets low in plant-based antioxidants allow oxidative stress to accumulate unchecked, driving low-grade chronic inflammation. This is a primary accelerant of cardiovascular disease, type 2 diabetes, and cognitive decline, all of which need to be taken incredibly seriously.” Ralph further comments.
Gut microbiome disruption
“Consuming foods that have reduced fibre and goodness degrades the diversity and stability of the gut microbiome within days. You’ll notice a huge effect on your mood, stress levels, immune function and metabolic regulation.” He says.
Ralph is extremely concerned about the intersection of food inflation with the UK Government’s ongoing welfare reform programme, which reduces financial support for some of the UK’s most vulnerable households.
He is calling for the government’s 10 Year Health Plan, which commits to shifting the NHS from sickness to prevention, to explicitly address food security as a health infrastructure issue, not merely a consumer affordability one.
“You cannot build a prevention-first NHS while the conditions that generate preventable disease are being actively worsened by geopolitical events and domestic policy simultaneously. Food is medicine. It is the most fundamental intervention in longevity and health span that exists. Right now, millions of people are being priced out of it.” Ralph concludes.
