It’s crucial to spot B12 deficiency promptly to be able to start the treatment. Otherwise, you could be risking developing “irreversible” damage. Apart from the traditional symptoms linked to this condition, your food choices could also hold clues.
It can be completely normal to want a specific food, however, Sas Parsad founder of The Gut Co explained that craving certain foods could be pointing to a bigger problem.
Mr Parsad said: “When you are low in vitamin B12, you have an iron deficiency.
“Our bodies crave nutrients we are lacking to let us know we need more of that substance for optimum body function.
“Our gut-brain axis controls this, with our gut and brain communicating through complex signals that communicate the health of both systems.”

This could trick your body into wanting specific foods.
The expert added: “Your body can crave foods that are high in iron such as marmite, twiglets, milk, salmon, egg yolks, tuna, chicken and other meats.
“These are all good sources of vitamin B12, so if your body is craving them, listen to it.”
However, if you follow a plant-based diet, you might not be able to replenish your levels through these options.

Fortunately, the NHS explains that there are some foods that still offer vitamin B12.
Sources include yeast extract, fortified breakfast cereals and soy products.
Although food cravings might signal the “sneaky” deficiency, as dubbed by the Harvard Medical School, there are also symptoms to spot.
From mouth problems to depression, the NHS detail the tell-tale signs of lacking this vitamin.
The health service warns it’s important for it to be treated “as soon as possible” to avoid any further problems.
It states: “Although many of the symptoms improve with treatment, some problems caused by the condition can be irreversible if left untreated.
“The longer the condition goes untreated, the higher the chance of permanent damage.”
From diet swaps to injections, there’s plenty you can do to replenish your levels once you get the condition confirmed.
