What really makes people obese?

Thursday, April 18th, 2013

If we are to make any progress in tackling the obesity crisis, we have to look again at what really makes us fat, an expert has claimed.

Gary Taubes, co-founder of the Nutrition Science Initiative, argued that our understanding of the cause of obesity may be incorrect, and that rectifying this misconception is “absolutely critical” to future progress.

“What we want to know,” he said, “is what causes us to gain weight, not whether weight loss can be induced under different conditions of semi-starvation.”

The history of obesity research is a history of two competing hypotheses of energy balance and endocrinology, Taubes wrote in an article published in this week”s BMJ.

Since the 1950s, conventional wisdom on obesity has been that it is caused by a positive energy balance – in other words we get fat because we overeat. The alternative hypothesis – that obesity is a hormonal or regulatory disorder – was dismissed after the second world war as being unworthy of serious attention.

Causes and treatment for hiccups

Thursday, April 18th, 2013

It’s not because someone is missing you, there is more of science to it! Hiccups – what are they? Read on to understand.

The sudden involuntary contraction of a powerful muscle called the diaphragm causes the vocal cords to shut producing the characteristic `hic’ sound of the hiccup. The diaphragm is a muscle separating the chest from the abdomen and it helps in breathing.

Causes of hiccups

  1. Most often, no cause can be determined for a hiccup. It stops as suddenly as it starts producing temporary discomfort.
  2. Drugs like diazepam, lorazepam , drugs  used to treat acidity, ondansetron used to control vomiting and others may cause hiccups as a side-effect.
  3. Hiccups commonly occur as a result of eating too fast, consuming fatty or spicy foods or swallowing a lot of air while eating. They may also occur due to having carbonated drinks or alcohol during the meal. The gas in the drink makes the stomach expand which irritates the phrenic nerve leading to hiccups.
  4. In some chronic conditions like kidney failure, diabetes, alcoholism, brain tumours involving the brainstem, liver disease, pneumonia and other lung problems, hiccups are reported.
  5. Breathing in poisonous fumes can also result in hiccups.
  6. Abdominal surgery may irritate the phrenic nerve resulting in hiccups.

All you need to know about walnuts

Thursday, April 18th, 2013

Ever since WebMD published a list of super foods, they have been taken up by every gullible business involved and taken to unprecedented proportions. And when joined the list, it created a few ripples. Looks like our forefathers had better insight and the Romans thought it was for better sexual health and infertility, ancient British doctors used it to treat mental disorders because the shape looks like a miniature brain and and
Greek doctors used to treat memory loss.

Today research shows us that the walnut does all of this and more. Infact, walnuts have more antioxidants in them than any other nut. They also contain very high amounts of omega 3 fatty acids which themselves have tonnes of goodness in them. It also has high amounts of alpha linonelic acid which is a type of omega 3 fatty acid but one with lots of effects on both the heart and brain.
