Previous claims that one or two alcoholic drinks a day doesn’t do any harm and could actually be protective are now in significant jeopardy following the publication of a large genetic study in The Lancet. According to the UK and Chinese researchers who followed 500,000 Chinese people over a 10-year period, the findings of the study are the best evidence yet on the direct effects of alcohol. While the negative health implications of heavy drinking are understood, the impact of consuming small amounts of alcohol on a regular basis has remained unclear. The researchers, from the University of Oxford, Peking University and the Chinese Academy of Medical Sciences, found that: drinking one to two alcoholic drinks every day increased stroke risk by 10-15% drinking four alcoholic drinks every day increased stroke risk by 35% For the purposes of the study, one drink was defined as either: a small glass of wine a bottle of beer a single measure of spirits In other words, even light-to-moderate drinking can increase blood pressure and a person’s chances of having a stroke. Prof David Spiegelhalter, from the University of Cambridge, said drinking alcohol on a daily basis gives the “opposite effect of taking a statin” (drugs that are used to lower cholesterol levels). The bottom line, according to Prof Richard Peto, professor of medical statistics and epidemiology at the University of Oxford, is the “claims that wine and beer have magical protective effects is not borne out”.
Do you know how much salt you consume on a daily basis? If you’re a fan of Chinese takeaway meals, it could be far more than you ever imagined, according to a campaign group. For their research, Action on Salt analysed more than 150 Chinese takeaway dishes from both restaurants and supermarkets. They found that most contained way too much salt – almost half the average person’s recommended daily amount of salt (6g) in some cases. When it comes to the saltiest meals, dishes like beef in black bean sauce topped the list. If a person adds a portion of egg fried rice, their salt intake could rise by as much as 5.3g in one meal. In fact, one portion of beef in black bean sauce and a side of vegetable noodles was found to contain as much salt as five Big Macs. While it’s vastly more difficult with Chinese takeaway food, Action on Salt recommends people check the nutritional information on supermarket bought food to see how much salt it contains. The campaign group says that many Chinese takeaway meals should carry health warnings because of the amount of salt they contain. Too much salt can lead to increased blood pressure, which can in turn increase a person’s risk of heart attack and stroke. Public Health England (PHE) has been encouraging the food industry to reduce the amount of salt found in food. Dr Alison Tedstone, chief nutritionist for PHE, said: "A loaf of bread has 40% less than it used to. "However, some products are still too high in salt and we know this can be reduced further. "We've been very clear with the food industry on the importance of meeting the 2017 salt targets. "We'll report on their progress this year and on any necessary advice to government on the next steps." So, the next time you reach to grab your favourite Chinese takeaway meal from the supermarket, just have a quick read of the nutritional information. What you discover might just make you choose something else instead.
Just one cigarette a day can increase a person’s risk of heart disease and stroke, a study has found, dispelling the myth that cutting back, not quitting altogether, can eliminate health issues. The study found that just one cigarette a day can increase a person’s chances of heart disease by about 50% and chances of a stroke by 30% than people who have never smoked. The bottom line is that there is no safe level of smoking when it comes to heart disease and stroke. Cardiovascular disease, not cancer, remains the greatest mortality risk for smokers, accounting for approximately 48% of smoking-related premature deaths. And while the number of people who smoke in the UK has been falling, the percentage of people smoking one to five cigarettes a day has been steadily rising, researchers said. However, cutting down on cigarettes is always a good start and people who do so are more likely to quit in the long-run. Prof Allan Hackshaw from the UCL Cancer Institute at University College London, who led the study, said: "There's been a trend in quite a few countries for heavy smokers to cut down, thinking that's perfectly fine, which is the case for things like cancer. "But for these two common disorders, which they're probably more likely to get than cancer, it's not the case. They've got to stop completely." For the study, the researchers at UCL analysed data from 141 separate smoking-related studies and published their findings in the BMJ.
