Drinking soft drinks is associated with higher blood pressure, according to a study of over 2,500 people reported this week in the journal Hypertension. High blood pressure is a major risk factor for heart disease, which is the leading cause of death worldwide. Someone with a blood pressure level in millimetres of mercury (mmHg) of 135 over 85 is twice as likely to have a heart attack or stroke as someone with a reading of 115 over 75.
The new research shows that for every extra can of soft drink consumed per day, participants on average had a higher systolic blood pressure by 1.6 mmHg and a higher diastolic blood pressure by 0.8 mmHg. This difference was statistically significant even after adjusting for factors such as weight and height. The study did not examine the mechanism that might link soft drinks with blood pressure. However, the researchers suggest that raised uric acid, which has been linked to soft drink consumption, might raise blood pressure by reducing the levels of nitric oxide, a chemical that relaxes the lining of the blood vessels.
The association between soft drinks and higher blood pressure was especially strong in people who consumed a lot of salt as well as sugar. Diet drinks were linked with lower blood pressure levels in some analyses, but the association was not consistent or strong. Professor Paul Elliott, senior author of the study, from the School of Public Health at Imperial College London, said: “It’s widely known that if you have too much salt in your diet, you’re more likely to develop high blood pressure. The results of this study suggest that people should be careful about how much sugar they consume as well.”
The researchers analysed data from 2,696 volunteers aged between 40 and 59, in eight areas of the US and two areas of the UK. On four separate occasions over a period of three weeks on average, the participants reported what they had eaten in the preceding 24 hours, as well as giving urine samples and having their blood pressure measured. The volunteers were taking part in INTERMAP, the International Study of Macronutrients, Micronutrients and Blood Pressure.
The researchers also found that people who drink more soft drinks tended to have more unhealthy diets in general. As well as consuming more sugar, those consuming more than one soft drink a day consumed more calories by 397 kilocalories per day on average, and less fibre and minerals. Those who did not consume soft drinks had a lower body mass index (BMI) on average than those who consumed more than one drink per day. “Individuals who drink a lot of sugar-sweetened beverages appear to have less healthy diets,” said Dr Ian Brown, the study’s first author, also from the School of Public Health at Imperial College London. “They are consuming empty calories without the nutritional benefits of real food. They consume less potassium, magnesium and calcium.” “This is a population study,” Dr Brown added. “It can’t say definitively that sugary drinks raise your blood pressure, but it’s one piece of the evidence in a jigsaw puzzle that needs to be completed. In the meantime, we would advise people who want to drink sugar-sweetened beverages should do so only in moderation.”
Women consuming too much red meat may have a higher risk of stroke than women eating less, says a new study. Red meat is high in saturated fat and cholesterol; both are risk factors for cardiovascular disease, heart attack, and stroke. The United States Centers for Disease Control and Prevention suggests lowering saturated fat intake and eating more fresh fruits and vegetables to help reduce your risk of stroke. Writing in the journal Stroke, researchers examined nearly 35,000 Swedish women, ages 39 to 73. None of the women had heart disease prior to the start of the study in 1997.
After ten years, results showed 4% of the study participants, 1,680 women, had a stroke. Those consuming the most red meat had the highest risk of stroke. Women in the top tenth of red meat intake, consuming at least 3.6 ounces each day, were 42% more likely to have a stroke, compared to women who ate just under one ounce of red meat daily.
Eating processed meat also increased stroke risk. Women eating 1.5 ounces of processed meat each day were 24% more likely to suffer a cerebral infarction, compared to woman consuming less than half an ounce of processed meat each day. Processed meat was not linked to any other form of stroke. Cerebral infarction is a type of stroke caused by a disturbance in the blood vessels supplying blood to the brain. Other types of stroke involve a rupturing of a blood vessel, called hemorrhagic strokes.
The scientists blame red meat and processed meat’s effect on raising blood pressure for the increased stroke risk. According to the World Health Organization (WHO), every year an estimated 17 million people die due to cardiovascular diseases, most notably stroke and heart attack. The WHO lists physical inactivity and unhealthy diet as the main risk factors for heart disease and major cardiac events.
Tomatoes are rich in cell-protecting antioxidants. Antioxidants are known cancer-fighters, such as prostate and breast cancer. And now lycopene – one of the antioxidants found in tomatoes – is being linked to reduce risk of osteoporosis. Osteoporosis is a degenerative bone disease, usually developing in old age, especially in post-menopausal women.
But the new study at the University of Toronto in Canada, says drinking tomato juice may help stave off osteoporosis. Published in the journal Osteoporosis International, scientists claim consuming 30mg of lycopene from tomato juice (about two glasses) is enough to help prevent osteoporosis. For the research, experts restricted a group of post-menopausal women, ages 50 to 60, from consuming anything containing lycopene for one month, then the study participants were split into four groups for four months. Groups were given either a 15mg lycopene supplement, a glass of tomato juice naturally containing 15mg of lycopene, a gourmet tomato juice with 35mg of lycopene, or a placebo.
After four months, results showed supplementing with lycopene raised serum lycopene, compared to the placebo group. The women consuming lycopene had significantly increased antioxidant capacity, decreased oxidative stress, and decreased bone markers for osteoporosis.
Here is another reason to make the tasty almonds a part of your daily diet. The humble tidbit nuts that combine tons of essential nutrients in one delicious package are an effective weapon in fighting type 2 diabetes and cardiovascular diseases, claims a new study. According to researchers, almonds added to the diet have a favorable effect on blood cholesterol levels and insulin sensitivity, two vital risk factors that can trigger diabetes and heart problems.
Lead author of the study, Dr. Michelle Wien, Assistant Research Professor in Nutrition at Loma Linda University’s School of Public Health stated, “We have made great strides in chronic disease research from evidence of effective treatment to evidence of effective prevention. “It is promising for those with risk factors for chronic diseases, such as type 2 diabetes and cardiovascular disease, that dietary changes may help to improve factors that play a potential role in the disease development.”
In a bid to assess the impact of almond enriched diet as a prescription for physical wellness, the researchers conducted a study. The focus of the study was to analyze the effect of the humble nut on the progression of type 2 diabetes and cardiovascular disease. The investigators enrolled a group of 65 adults comprising 48 women and 17 men with pre-diabetes in their mid-50s. The study subjects were split into two groups. As a part of the study, one group was assigned to almonds while the second formed the control group. The control group followed a diet recommended by the American Diabetes Association (ADA).The group assigned to almonds conformed to a similar diet but also added 20 percent calories from almonds. All the participants were asked to consume the same amount of calories from carbohydrate-containing foods, such as pasta, bread, and rice. However, those consuming the almond-enriched diet reported a lower intake of carbohydrate-containing food items.
After a period of 16 weeks, the investigators compared the insulin and cholesterol levels of both the groups. It was noticed that people consuming almond-enriched diet exhibited marked improvement in their insulin sensitivity and a dramatic reduction in LDL cholesterol as opposed to those eating the nut-free regular diet.
The study was conducted at the University of Medicine and Dentistry of New Jersey. The findings of the research are published in the ‘Journal of the American College of Nutrition
Good nutrition is important at every stage of life, from infancy through late adulthood. The basics of a balanced diet remain the same but individual nutritional needs change as you grow older. No matter what your age, it is never too late to start living a healthier life.
Whether you are 50 or 85, active or homebound, your food choices will affect your overall health in the years ahead. The risk for certain diseases associated with aging such as heart disease, osteoporosis and diabetes can be reduced with a lifestyle that includes healthy eating. Good nutrition also helps in the treatment and recovery from illness. While healthy living can't turn back the clock, it can help you feel good longer.
Eating healthfully means consuming a variety of good foods each day. Food provides the energy, protein, vitamins, minerals, fiber and water you need for good health. For one reason or another your body may not be getting the right amounts of these nutrients.
There are several factors that indicate an increased risk for poor nutrition. If you have three or more of the risk factors listed below consult with Nastaran or your doctor:
- ill health
- poor eating habits
- unexpected weight gain or loss
- taking medications
- poor dental health
- economic hardship
- loneliness and lack of social contacts
- the inability to care for yourself
