Fried fish raise heart failure risk

A new study has warned that consuming fried fish and chips even once a week increases the risk of heart failure, compared to baked or grilled fish which reduces the chances by 30 per cent.

Researchers have claimed that frying fish not only nullifies the beneficial effects, but also reverses them and increases the risk of heart failure by almost 50 per cent.  They analysed the eating habits of 84,493 women aged 50 to 79 over a period of eight years.

The results showed that those who consumed five or more portions of baked or boiled fish in a week were found to reduce their heart attack risk by 30 per cent.

On the other hand, those who ate fried fish increased their chances of heart failure by as much as 48 per cent. The women were also more likely to be overweight . The researchers concluded that people who had baked or grilled fish regularly, were more active, fit and less likely to smoke. “Using healthier methods, such as baking, grilling or steaming instead of frying, will help us look after our hearts in the long term,” said Victoria Taylor, senior heart health dietitian .

Strength training in old age maintains mobility

A new study has revealed that regular strength (resistance) training in old age is important to maintain mobility and to manage everyday tasks independently.

People lose 30 per cent of their muscle strength between the ages of 50 and 70 years. However, the study found that regular strength training increased muscle strength, reduced muscular atrophy, and that tendons and bones adapt too.

These successes in turn had a preventive effect in terms of avoiding falls and injuries. The authors investigated the extent of the effects that could be achieved by strength training in elderly persons and which intensities of exercise are useful and possible in persons older than 60 years.

They found that greater intensities of training yielded greater effects than moderate and low intensities. In order to increase muscle mass, an intensity of 60-85 per cent of the one-repetition-maximum is required and to increase rapidly available muscle force, higher intensities, more than 85 per cent is required. They also said that the optimum amount of exercise for healthy elderly persons is 3 to 4 training units per week.
