Midnight snacks may up heart risk, diabetes

midnight-snacking

New York, Nov 8: Are you in the habit of late night snacking? Beware, as people with this habit have a higher risk of developing various heart diseases and diabetes, says a new research.

Late night eating habits disrupt the working of the body’s biological clock. It is out-of-sync with the 24-hour cycle, resulting in high blood-fat levels and heart problems, the researchers found.

“The fact that we can ignore our biological clock is important for survival; we can decide to sleep during the day when we are extremely tired or we run away from danger at night,” said Ruud Buijs, Professor at the University of Mexico in Mexico City.

“However, doing this frequently — with shift work, jet lag, or staying up late at night — will harm our health in the long-term, especially when we eat at times when we should sleep,” Buijs added.

The researchers studied rats who were subjected to a challenge. They were fed during the beginning of rest phase (day) and the beginning of active phase (night).

The results showed that after feeding the rats at the beginning of their rest period, the level of blood fat spiked more drastically than when fed during the beginning of their active phase.

The research, published in the journal Experimental Physiology, revealed no change in the blood fat levels when the researchers removed the part of the rat’s brain that controls the 24-hour cycle.

It was evident that the presence of blood fat in high levels not only affected the metabolism rate but also increased the chance of various heart diseases and diabetes.

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

Published

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

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.
