It's the same advice that mothers everywhere have been giving for years, but now there's science to back it up: Eating veggies is good for the eyes. A new study from the University of Wisconsin confirmed that women who have a healthy diet, exercised regularly and didn't smoke were less likely to suffer macular degeneration as they got older. Macular degeneration is the leading cause of vision problems in older people in the United States, researchers said.
The study of 1,313 women from Oregon, Iowa and Wisconsin is the first to look at several lifestyle factors that influenced age-related macular degeneration (AMD), according to a release from the university. These findings show a healthy lifestyle can improve the chances of good eyesight for those who inherit the condition, according to Dr. Julie Mares of the UW School of Medicine and Public Health.
According to the study, 18 percent of women deemed to have unhealthy lifestyles developed early AMD while just 6 percent of women in the healthy-lifestyle group developed the condition. Researchers found that the association of healthy eyes and healthy overall diets was stronger than what they observed for any single nutrient. Women whose diet score was the in top 20 percent had a 50 percent lower prevalence of early stages of macular degeneration than woman with the lowest percent for healthy diet scores. Higher scores were given to those with more leafy green and orange vegetables, fruits, dairy, grains and legumes, according to the release.
Mares said this was the first study where researchers found higher levels of physical activity lowered the likelihood of early macular degeneration. However, this study didn't show obesity was related to AMD, but obese women were more likely to have more macular degeneration. That trend was explained by a poor diet and low physical activity, according to the university. The study also confirmed other studies that smoking played a role in eye disease.
The university said the study is being published online in the Archives of Ophthalmology, a journal of the American Medical Association. The research was funded by the National Institutes of Health, National Eye Institute. It was also supported by the Research to Prevent Blindness and the Retina Research Foundation.
The American Heart Association has compiled its annual list of the top 10 major advances in heart disease. “We have come far in the past decade, reducing heart disease deaths by more than 27 per cent,” said Ralph Sacco of the University of Miami. “But we know there is still much to be done in improving the lives of heart disease and stroke patients – and more importantly, in preventing these devastating diseases in the first place. Scientific research will help us lead the way,” said Sacco.
The highlights of the top ten advances in cardiovascular research in 2010:
1. Tailoring treatment for people with diabetes to reduce their risk of cardiovascular disease
New research from the ACCORD Study Group offered insight into specific treatments that can reduce their risk of cardiovascular disease (CVD). The first study found that aggressive blood pressure control does not reduce CVD risk in people with type 2 diabetes at high risk for CVD. In a second study, a combination therapy with a statin plus a fibrate was no better at reducing risk than a statin alone in patients with type 2 diabetes at high risk for CVD.
2. New advances for patients who aren't candidates for conventional valve surgery
Two new studies have supported evidence that Transcatheter aortic valve implantation (TAVI) can improve symptoms and outcomes – including quality of life – even over the course of several years. While there are some risks associated with TAVI, including strokes and other major cardiovascular events, the catheter-based procedure offers significant progress in this area.
3. Improving the way we reverse sudden cardiac arrest
Significant studies reported that chest compression only, or ''Hands Only CPR'' for adults by bystander lay rescuers improves survival outcome. Public awareness campaigns resulted in increased use of hands only CPR, as well as improved survival rates. While the new procedure appeared successful in adults, it is important to note that using conventional chest compressions with rescue breathing is still important for children stricken with sudden cardiac arrest.
4. More options for reducing stroke risk in atrial fibrillation
For the first time in more than 20 years there are viable alternatives to the primary prevention of stroke for patients with atrial fibrillation (AF). Warfarin (Coumadin) has long been the standard anti-clotting drug used to reduce the risk of stroke for these patients. But it carries its own complications from bleeding, and managing the dose requires regular blood tests, making it difficult to manage for both patients and doctors. Now, several new drugs have been found to work as well as warfarin – and are simpler for patients to take – offering an important advance in this field.
5. Adjusting pacing therapies can improve outcomes for heart failure patients
New studies showed that adding additional resynchronization pacing to ICD therapy could lead to improved outcomes in an expanded group of heart failure patients. In addition, new types of ICDs (defibrillators without leads, for example) can offer options that reduce some of the risks associated with traditional devices.
6. Hopeful new procedure for infants with congenital heart disease
The Pediatric Heart Network's randomized trial of Norwood shunt types in infants with single-ventricle lesions showed that the type of shunt used makes a difference in outcomes. Better transplantation-free survival at 12 months is a possibility with this new understanding of the better shunt choice for these patients. This was the first large-scale randomized trial in congenital heart surgery, offering an approach that should provide answers to other questions in the future.
7. Finding the right anti-clotting (anti-platelet) therapy
New research from the PLATO investigators has found that ticagrelor may improve outcomes and reduce adverse events better than the current standard, clopidogrel. The CURRENT-OASIS 7 Trial is exploring the optimal dosing of clopidogrel and aspirin in patient undergoing invasive surgery. These studies will help providers better understand the situations where new choices and dosages may improve results for the patient.
8. Basic science findings offer insight into future progress
Several studies this year brought the future of medicine closer to the present with new insight into emerging technologies. Findings from stem cell therapy have shown improved quality of life and survival in several early studies of patients with chronic heart failure and support the development of future cell-based therapeutics. A large animal study defined the basic mechanisms for heart muscle regeneration initiated by specific types of stem cells. The results demonstrated that these stem cells repair scarred myocardium through promotion of the generation of new heart muscle and blood vessel).
9. Using science to support healthy lifestyle behaviours
New science examining lifestyle behaviours in adults and children, with particular emphasis on physical activity and consumption pattern, show that such conditions as obesity and hypertension are positively influenced by a change in diet with decreasing sodium levels. Results from the school setting suggest that the earlier one starts to adopt healthy behaviours the better the effect on health outcomes.
10. Get With The Guidelines participation eliminates disparity gaps in care
Racial and ethnic disparities have been found in the quality of care delivered to patients with cardiovascular disease and achieving equity and addressing disparities has implications for quality, cost, risk management, and community benefit. These findings are the first to show that participating in a quality improvement program, such as Get With The Guidelines-Coronary Artery Disease, can eliminate racial and ethnic disparities of care while increasing the overall use of evidence-based care for heart attack patients.
Individuals with either type 1 or type 2 diabetes know that maintaining a nutritious diet is one of the most important things they can do to control their disease. The findings of a new study suggest that the services of a registered dietitian may help individuals accomplish this goal.
A team of investigators from the American Dietetic Association reviewed evidence from previous research and summarized their findings in a report published in the Journal of the American Dietetic Association.
In their write-up, researchers laid out a set of exhaustive dietary guidelines for individuals affected by diabetes. Researchers said that the services of registered dietitians may be key in helping individuals follow the guidelines, which could help them significantly improve their condition.
“The evidence is strong that medical nutrition therapy provided by registered dietitians is an effective and essential therapy in the management of diabetes. Registered Dietitians are uniquely skilled in this process,” said Marion Franz, who led the investigation.
The guidelines developed by the research team lay out 29 nutritional points that can help diabetics improve their blood sugar control.
The new study comprised 366 people with RA from eight separate trials. Fasting followed by eating a vegetarian diet for 13 months or eating a Mediterranean style diet replete with fruits, vegetables, healthy fats, and legumes for 12 weeks may relieve pain, the study showed. These diets did not improve morning joint stiffness or physical function when compared to regular diets.
There was not enough data to draw any conclusions about how vegan and/or elimination diets affect RA symptoms.
The positive changes seen with vegetarian and Mediterranean diets may be a result of simply adapting a healthier way of eating as opposed to any specific diet, the study researchers conclude.
People with RA who were put on special diets were more likely to drop out of the studies, suggesting that some people may have difficulty adhering to the eating plans.
Some special diets also resulted in weight loss which may not always be a good thing people with RA who are already at risk for nutritional shortfalls.
“There is a need for more and better research on dietary interventions for RA,” conclude researchers led by Geir Smedslund, PhD, a senior researcher at the Centre for Rehabilitation in Rheumatology at the Diakonhjemmet Hospital in Oslo, Norway.
Due to loss of loved ones, health problems, trouble paying bills, or other reasons, many older people feel lonely, sad, or stressed in their daily lives.
