An urgent warning has been issued over 'deadly salt tooth' after government figures showed Brits' daily salt intake is on average above the recommended amount.
Campaigners are urging people to curb their salt tooth to safeguard their health and reminding people that excessive salt can significantly increase the risk of heart attack and stroke.
Some salt is vital for our health - table salt, aka sodium chloride, contains around 40 per cent sodium, an essential nutrient.
Eaten in a small quantity, sodium helps the conduction of nerve impulses, muscle contraction and relaxation, and helps maintain the balance of water and minerals. A lack of salt can lead to muscle cramps, nausea, fatigue and light-headedness
However, consuming more than the 6g a day recommended by the NHS for adults – equating to around one teaspoon – can be detrimental for your health .
However, a person living in the UK’s average daily intake is 8g, according to Government figures, which is of major concern as excess salt leads to hypertension and high blood pressure, reports MyLondon.
For every 1g of salt cut from the average daily UK diet there would be an estimated 4,147 fewer premature deaths, saving the NHS £288 million each year.
Launching for Salt Awareness Week, Season With Sense is calling on people to take part in its ‘Stick to Six’ challenge, which invites participants to begin monitoring their salt intake.
Olivia Burley, registered associate nutritionist who is currently working on the NHS Diabetes Prevention Programme said: "A high salt intake disrupts the natural sodium balance in the body.
"Hypertension is a condition where blood pressure remains elevated over time, which can increase the risk of heart and circulatory diseases."
Examples of foods high in salt can be canned fish or poultry, frozen foods such as breaded meats, salted nuts, canned beans, cured meats, soup and sandwiches.
And just because you’ve drunk enough water to quench your thirst doesn’t mean you’re negating the effects of too much salt, which is why it’s important to be aware of other health indicators..
Four signs you’ve eaten too much salt
Headaches
The dehydration caused by excess salt intake can lead to severe headaches. Pippa Hill, nutritionist and founder of The Weight Loss Guru said:
“These headaches tend to be more painful than a mild one, giving a throbbing sensation as the blood vessels are being expanded,” Hill says.
“They tend to come on between an hour or two after you’ve eaten, as sodium levels rise through the body.”
They may come on quicker if you have high blood pressure or suffer from chronic headaches in general, but can often be solved by rehydrating.
Hill added: “As your water levels are imbalanced, by drinking more water you’re able to minimise and get rid of the headache.”
Swollen feet and hands
Also known as edema, swelling of the fingers, ankles or feet can be a delayed reaction to a spike of sodium.
“When too much salt is consumed, the body retains the extra sodium and increases the fluid outside of the cells, Burley explains.
“This causes the kidneys to have reduced function, remove less water and therefore increase blood pressure.”
Swelling may occur more when sitting down for too long or on long journeys.
“This isn’t an instant response after eating, but if in the next 24 hours of having eaten salty foods you notice swelling in these areas, it could be a link,” Hill says.
“It’s best to seek medical advice if this is an ongoing occurrence, as it could be a sign of a more serious health concern.”
High blood pressure
“Salt is the largest cause of high blood pressure,” Hill warns. “Within just 30 minutes, eating excess salt will have a bodily reaction to the blood vessels.”
Also called hypertension, if left untreated it can increase your risk of serious problems such as heart attacks and strokes.
Hills says: “If after eating a salty diet, your symptoms include blurred vision, chest pain such as a tight feeling, palpitations, shortness of breath or sudden nosebleeds, it could mean you have a raised blood pressure.”
Hypertension can often have no symptoms and the only way to know your blood pressure is to get it monitored using a machine.
Frequent urination
Excessive thirst is a common response to eating salty foods and naturally leads to an increase in fluid consumption, causing excessive urination.
By sending the signal that you need to guzzle lots of liquid, the body aims to remove the excess salt build-up.
Although drinking more fluids in response to an increase in salt is one of the main reasons for urine production, it could be a symptom of other conditions like polyuria, therefore medical checks are best, nutritionists advice.
