Low Carb Diet Chest Pain
GOING carb-free may speed up your weight loss (temporarily), but it won't do your heart any favours.
Scientists have found that people who cut pasta, bread and grains to lose weight increase their risk of heart problems by a FIFTH.

Don't ditch the pasta - it may just save your life!Low-carb plans like the Keto, Atkins and paleo diets tend to see people getting fewer calories from grains, fruits and starchy veg.
But scientists in China warn cutting carbs increases the risk of atrial fibrillation (AFib) by 18 per cent.
It's the most common form of heart rhythm disorder - causing an irregular, often abnormally fast heart beat. Sufferers are at greater risk of stroke and heart failure.
Scientists looked at the health records of nearly 14,000 people over a 20-year period. None of them had AFib when they enrolled in the study, but nearly 1,900 went on to be diagnosed with it by the end.

All of the participants were asked to report their daily intake of 66 different food items.
Researchers then estimated each person's daily carb intake and the proportion of calories that came from carbs every day.
On average, carbohydrates made up half of the calories consumed.
Scientists then divided participants into three groups: low, medium and high carb intake.
Symptoms of atrial fibrillation?
AFib is a condition that causes an irregular and often abnormally fast heart rate.
A normal heart rate is thought to be between 60 and 100, but people with AFib will have one way above 100.
People with atrial fibrillation are at increased risk of having a stroke. In extreme cases, atrial fibrillation can also lead to heart failure.
When the heart beats normally, its muscular walls contract (tighten and squeeze) to force blood out and around the body.
They then relax so the heart can fill with blood again. This process is repeated every time the heart beats.
In atrial fibrillation, the heart's upper chambers (atria) contract randomly and sometimes so fast that the heart muscle cannot relax properly between contractions. This reduces the heart's efficiency and performance.
Atrial fibrillation occurs when abnormal electrical impulses suddenly start firing in the atria.
These impulses override the heart's natural pacemaker, which can no longer control the rhythm of the heart.
Symptoms include:
- heart palpitations
- tiredness
- breathlessness
- feeling faint
- chest pain
See your GP immediately if you notice a sudden change in your heartbeat.

They found that those on low-carb diets were 18 per cent more likely to develop AFib than those with moderate carb intake, and 16 per cent more likely than those with high carb intake.
So why should that be?
Well, lead author Dr Xiaodong Zhuang, a cardiologist at the hospital affiliated with Sun Yat-Sen University in Guangzhou, China, said one reason could be all the anti-inflammatories these people are missing out on.
Fruit, veg and whole grains are known to reduce inflammation - something we know is behind many chronic conditions.

Another explanation is that eating more protein and fat instead of carbs can increase oxidative stress - which is associated with AFib.
Low-carb diets have become increasingly popular in recent years as a means of losing weight via sugar restriction.
But previous studies have found that both low-carb and high-carb diets come with an increased risk of death.
And it doesn't matter what you replace that missing carb element with, your heart may suffer just the same.
"Low carbohydrate diets were associated with increased risk of incident AFib regardless of the type of protein or fat used to replace the carbohydrate," Dr Zhuang said.
Last summer, we reported that experts had found cutting carbs "increases the risk of early death".
But more research is still needed to work out if poor heart health is caused directly by eating fewer carbs.
Aid heart with a big breakfast
EATING a big breakfast helps to keep your heart healthy, a study found.
Having an energy rich meal with more than 20 per cent of daily calories lowers the risk of heart disease and stroke.
Scoffing milk, cheese, cereals, bread and honey reduced plaque build-up in people's arteries.
The Greek researchers, who studied 2,000 people, said those who ate a big breakfast tended to then have healthier food for the rest of the day.
Their study also found watching less telly was good for you. Spending 21 hours a week in front of the box increased the risk of high blood pressure by 68 per cent and diabetes by 50 per cent.
Lead researcher Dr Sotirios Tsalamandris said: "A high energy breakfast should be part of a healthy lifestyle."

At the moment all we can say is that there's an association.
"The long-term effect of carbohydrate restriction is still controversial, especially with regard to its influence on cardiovascular disease," said Dr Zhuang.
"Considering the potential influence on arrhythmia, our study suggests this popular weight control method should be recommended cautiously."
