A snapshot of the current thinking in medicine, fitness and lifestyle trends that impact your life.
Anxiety raises risk of death in heart patients
People with heart disease who have anxiety are twice as likely to die compared to those without anxiety, a new study shows. And those with both anxiety and depression have a tripled risk, reports the Journal of the American Heart Association.
Studies show that depression is about three times more common in heart patients. The American Heart Association recommends that heart patients be screened for depression.
The link between depression and mortality is more related to behavioural risk factors, such as overeating, smoking and drinking.
Zinc, vitamins C and E benefit eye health
High levels of antioxidants and zinc, in the form of a nutritional supplement, reduce the risk of advanced age-related macular degeneration (AMD) - a leading cause of blindness in older people after cataract. These supplements are not a cure for AMD, but they reduce the further risk.
Carrot has long been connected with improving vision due to its high level of beta-carotene but that's only isn't enough. Few things to have are:
Fruits and vegetables - Vitamin C can help minimise cataracts and AMD
Fleshy fish (tuna or salmon) and lean meats - Fatty acids protect against AMD
Red meats and whole grains - Zinc deficiency can lead to cataract
Vegetable oil - Vitamin E can slow progression of AMD.
Work stress driving Britons to drink
Work stress is the biggest factor in driving Britons to drink, drugs and depression, say mental health experts. More than a third (34%) of adults say their job is the most stressful aspect of their lives - more so than money (30%) or health worries (17%).
Apart from alcohol, people also turn to sleeping pill, anti-depressants and smoking to cope. Almost six in 10 (57% ) of people hit the bottle after work - with one in seven (14%) even drinking during the day, a survey for mental health charity Mind found.
Walking protects women from stroke
Women who walk at least three hours every week are less likely to suffer a stroke than women who walk less or not at all, shows new study. Past studies have also linked physical activity to fewer strokes, which can be caused by built-up plaque in arteries or ruptured blood vessels in the brain.
Women who were regular walkers showed a 43% reduction in stroke risk compared to the inactive group, reports the journal Stroke. There was no reduction seen for men based on exercise type or frequency.
Those who walked briskly for 210 minutes or more per week had a lower stroke risk than inactive women but also lower than those who cycled or did other high-intensity workouts for short duration.
Soybean proteins fight cancer
Proteins found in soybeans, could inhibit growth of colon, liver and lung cancers, a new study has revealed. Soybean is rich in protein, which usually makes up around 40% of the nutritional components of the seeds and dependent on the line, and can also contain high oleic acid (a monounsaturated omega-9 fatty acid).
The study found that soybean significantly inhibited cell growth by 73% for colon cancer, 70% for liver cancer and 68% for lung cancer cells using human cell lines. This shows that oleic acid-packed soybeans have a potential nutraceutical affect in fighting cancer, reports the study published in Food Research International.
