Eating too much sweets bad for heart

Published

on

London, Oct 5, 2017: Drinking too many soft drinks and eating a lot of sweets may put even otherwise healthy people at increased risk of heart disease, warns new research.

The study, published in the journal Clinical Science, showed that healthy men had increased levels of fat in their blood and fat stored in their livers after they consumed a high sugar diet.

“Our findings provide new evidence that consuming high amounts of sugar can alter your fat metabolism in ways that could increase your risk of cardiovascular disease,” said Bruce Griffin, Professor of Nutritional Metabolism at the University of Surrey in England.

The researchers looked at two groups of men with either high or low levels of liver fat and fed them a high or low sugar diet.

The low sugar diet contained no more than 140 calories a day worth of sugar – an amount close to the recommended intake – while the high sugar diet contained 650 calories worth.

After 12 weeks on the high sugar diet, the men with a high level of liver fat – a condition known as non-alcoholic fatty liver disease (NAFLD) – showed changes in their fat metabolism that are associated with an increased risk of cardiovascular disease, heart attacks and strokes.

Fat metabolism is the biochemical process by which fats are transported and broken down in the blood, and used by the cells of the body.

The results also revealed that when the group of healthy men with a low level of liver fat consumed a high amount of sugar, their liver fat increased and their fat metabolism became similar to that of the men with non-alcoholic fatty liver disease.

“While most adults don’t consume the high levels of sugar we used in this study, some children and teenagers may reach these levels of sugar intake by over-consuming fizzy drinks and sweets,” Griffin said.

“This raises concern for the future health of the younger population, especially in view of the alarmingly high prevalence of NAFLD in children and teenagers, and exponential rise of fatal liver disease in adults,” Griffin added.

Sunscreen can reduce skin cancer risk by 40% in youth: Study

sunscreen Skin care

Sydney, July 20: Young adults who regularly use sunscreen to reduce their risk of skin cancer by 40 percent, a study has found.

According to the World Health Organization (WHO), between two and three million non-melanoma skin cancers and 1,32,000 melanoma skin cancers occur each year globally.

The global incidence of melanoma continues to increase, however, the main factors that predispose to the development of melanoma seem to be connected with recreational exposure to the sun and a history of sunburn. These factors lie within each individual’s own responsibility.

“The association of sun exposure and sunburn with melanoma risk, particularly in childhood, is well established and this study showed that regularly using sunscreen was protective against the harmful effects of sun exposure,” Xinhua news agency quoted lead researcher Anne Cust, Associate Professor at the University of Sydney in Australia, as saying.

Cust noted that it is still difficult to get people to regularly apply sunscreen, and that likelihood to do so depended on a number of factors.

“Regular users of sunscreen were more likely to be female, younger, of British or northern European ancestry, and have higher education levels, lighter skin pigmentation, and a strong history of blistering sunburn,” Cust said.

“People were less likely to use sunscreen if they were male, older, less educated, or had skin that was darker or more resistant to sunburn.”

For the study, the team analysed data of around 1,700 people aged between 18 to 40 years.

“This study confirms that sunscreen is an effective form of sun protection and reduces the risk of developing melanoma as a young adult,” Cust said.

5 natural methods to beat stress

stress work tension

New Delhi, July 19: A study of 200,000 respondents by Optum has found that 46 per cent of the Indian workforce reports suffering from some form of stress.

Stress is the body’s natural response to pressure. It can have a negative effect on your body, mood, as well as behaviour, with wide-ranging effects like headaches, anxiety, fatigue and irritability.

The causes of stress vary from one person to the next, and so do the effects. Stress can be harmful for the body, and is the cause of many health and lifestyle problems. Managing stress should be a priority, but is often difficult to achieve due to lack of time or effective and simple methods to do so.

Dr Hariprasad, Ayurveda Expert at The Himalaya Drug Company, recommends the following natural methods to cope with stress:

Unwind with physical activity: All forms of physical activity are useful in managing stress. Exercising has many benefits such as releasing endorphins and calming the mind, with a reduction in stress levels being an added bonus. Even 45 minutes of physical activity a day goes a long way towards managing stress levels.

Organise your life: Organising one’s workload leads to a sense of control and peace of mind, and there are many ways to achieve this. One way to do this is through adopting good time management, by prioritising tasks, and scheduling time to complete them. Switching between tasks and having them pile up often becomes an additional source of stress. Decentralisation of tasks or asking for help as and when required is also a good way to reduce stress levels.

Use herbs in daily diet: Herbs like Ashvagandha have been proven to be effective in managing the negative effects of stress. According to Ayurveda texts and modern research, Ashvagandha helps reduce the damaging effects of long-term stress by rejuvenating the mind and body. It is an adaptogen that helps the body stabilise physiological processes, maintain a healthy balance between different biological systems, and support better resilience to stress.

Eat the right food: Your eating habits have a significant impact on stress levels. Following a healthy diet with a good balance of different food groups and all the required nutrients is essential. A diet rich in different food groups such as vegetables, fruits, whole grains, dairy, fish, and poultry would help you get the carbohydrates, proteins, fat, vitamins and minerals you need. A well-nourished body is better able to cope with the physical and emotional effects of stress.

Get enough sleep: Sleep is essential in stress management. Not getting enough sleep typically leads to irritability and fatigue. Oversleeping can make us sluggish, depressed — and puts our health at a higher risk. Getting the right amount of sleep, between 7-8 hours, is a good way to stay energised and effectively manage the challenges of the day.

In this busy and stressful life, these simple and natural methods can help you manage stress and maintain good mental and physical health.

Decoded: How Omega-3 fatty acid helps inhibit cancer’s spread

Published

New York, July 16: While eating foods rich in omega-3 fatty acids, such as fatty fish, certain nuts and seeds, have been known to prevent heart diseases and arthritis, a new research, led by one of Indian-origin, showed that omega-3 fatty byproducts may also have anti-cancer effects.

The new study, led by Aditi Das from University of Illinois at Urbana-Champaign, US, showed that when the human body metabolises omega-3 fatty acids, it produces a class of molecules called endocannabinoid epoxides, or EDP-EAs. These have anti-inflammatory properties and can inhibit cancer’s growth and spread.

The EDP-EAs have similar properties to cannabinoids found in marijuana — but without the psychotropic effects — and they target the same receptor in the body that cannabis does.

“We have a built-in endocannabinoid system which is anti-inflammatory and pain-reducing. Now we see it is also anti-cancer, stopping the cells from proliferating or migrating,” said study leader Aditi Das from University of Illinois at Urbana-Champaign.

“These molecules could address multiple problems: cancer, inflammation and pain,” Das added.

For the study, published in the Journal of Medicinal Chemistry, the team studied the effect of the molecule in mice with tumours of osteosarcoma — a bone cancer that is not only painful but also difficult to treat.

The results showed that the endocannabinoids slowed the growth of tumours and blood vessels, inhibited the cancer cells from migrating and caused cancer cell death.

The higher concentrations of EDP-EAs did kill cancer cells, but not as effectively as other chemotherapeutic drugs on the market. But, the compounds slowed tumour growth by inhibiting new blood vessels from forming to supply the tumour with nutrients. They also prevented interactions between the cells, and most significantly, they appeared to stop cancerous cells from migrating.

While dietary consumption of omega-3 fatty acids can lead to EDP-EAs, for those with cancer, something concentrated and fast acting is needed, Das said.

“That’s where the endocannabinoid epoxide derivatives come into play – you could make a concentrated dose of the exact compound that’s most effective against the cancer. You could also mix this with other drugs such as chemotherapies,” she added.
