It is packed with saturated fat which can raise "bad" cholesterol, says the American Heart Association in updated advice.

Coconut oil is commonly sold as a health food and some claim the fat in it may be better for us than other saturated fats.

The AHA, however, says there are no good studies to support this.

Many doctors recommend a glass of wine or beer a night as part of diet plans such as the Mediterranean diet and the DASH diet, which have been proven to keep your heart and brain healthy. However, a new study suggests that even moderate drinking may not be great for your brain.

Of the 4 million deaths attributed to being overweight in 2015, nearly 40% were not considered clinically obese.

The study found more than 2 billion children and adults suffered from health problems linked to being overweight.

These include type 2 diabetes, heart disease and some cancers.

But an increasing percentage had a body mass index (BMI) of less than 30, the threshold for obesity.

Men, especially in the older age group, and people living in the most deprived areas, were also more also vulnerable to premature death.

Influenza kills about 500 New Zealanders each year and probably the biggest single infectious disease killer, the study from the University of Otago, Wellington said.

Researchers found that in the 65-79 year age group, Māori were 3.6 times more likely to die of influenza than those of European or other ethnicity.

A loving spouse might spur you on to look after yourself better, they told a heart conference, based on their study of nearly a million UK adults.

The right GP can make a big difference to how healthy you are and may ultimately save your life.

As well as diagnosing illness, a good GP can draw your attention to problems you never knew mattered, decide if you need certain tests, refer you to the right specialists, monitor your progress, offer reassurance or advice, and keep you out of hospital or limit the care you need there.

If you have a chronic or serious illness, your GP relationship will be especially important.

So what should inform your choice?

The sea of weird and wonderful classes now available has had most people contemplating at least one new talent or skill that they believe will make them more fit, limber or relaxed.

Trampolining, meditation, barre classes and pole dancing are fairly well-established. Various iterations of yoga are joining in, including more unusual formats alongside goats or cats, or encouraging laughter as you hold that downward dog.

But observations and research show this is generally not the case.

Instead, people tend to make choices based on how food tastes. Typically, the more sugar, salt and fat in the food, the more we will like it.

Genetics, experience and environment also influence our perception of food and the consumption choices we make.

Who would have thought silkworms could be used to repair damaged eardrums?

A team with researchers based in Perth and Melbourne is moving towards clinical trials of a device that incorporates silk in an ear implant.

Named "ClearDrum", it looks like a contact lens, but is instead a device on which the patient's cells can grow.

Perth-based surgeon Professor Marcus Atlas said silk was the preferred choice because it was flexible.

I can have the requisite eight hours, no screens, fresh air and dim light and still wake up feeling knackered.

So, when a stranger sees me gazing at breathing apparatus in the local chemist and introduces herself as a 'CPAP disciple', I'm happy to listen.

CPAP stands for Continuous Positive Airway Pressure and it is basically a mask you wear on your face that is powered by a machine which pushes air into your throat to stop your airway closing while you're asleep.
