Why eating with your hands is good for health

Most Indians eat with their hands. But today as we adopt more traditions of the western world, it is common to see people using spoons and forks to eat. But did you know that eating with your hands has a number of health benefits? Here are the top 4 reasons you should start eating with your hands.

Why eating with your hands is good for health

Keeps all your vital life energies in balance: According to Ayurvedic texts, we are all made up of five main pranas or life energies and these five elements correspond to each finger on our hand (your thumb indicates fire, index finger correlates with air, middle finger indicates sky, ring finger stands for earth and little finger indicates water). An imbalance of any one of these elements can lead to diseases. When we eat with our hands we usually join our fingers and thumb to eat, this is actually a mudra that is a form of mudra vigyan, or the study of mudras and their healing power on the body. Therefore when we eat we are putting together all the five elements and energizing the food we eat so it helps us become healthy and keep all our pranas in balance.

Improves digestion: Touch is one of the most strong and often used sensation in the body. When we touch our food with our hands, the brain signals our stomach that we are about to eat. This in turn, readies the stomach to digest the food it will receive, aiding in better digestion.

Promotes mindful eating: Eating with your hands requires you to pay attention to what you are eating. You often need to look at the food and focus on what you are putting into your mouth. Also known as mindful eating, this practice is much more healthier than eating with a fork and spoon that can be done mechanically. Mindful eating has a large number of benefits for your health and one of the most important benefits is the fact that it improves the assimilation of nutrients from the food you eat, enhances digestion and makes you healthier.

Protects your mouth from getting burnt: Your hands also act as a very effective temperature sensor. When you touch food it is easy for you to gauge how hot it actually is, and you are less likely to put food that is too hot into your mouth – effectively preventing you from scalding your tongue.

Four myths about corn you should stop believing

Four myths about corn you should stop believing

There is nothing like sinking your teeth in a crisp cob of sweet corn. But few myths keep people away from the vegetable and it is time to know the truth.

Here are some of the biggest misconceptions surrounding sweet corn (only in the form of a vegetable):

  •  Corn is unhealthy – No! Corn is a vegetable that contains a lot of nutrients. The idea that corn is unhealthy likely came about because corn is high in starch.
  •  Your body cannot digest corn – While it’s true that corn has high amounts of insoluble fiber but this is not at all a bad thing. Insoluble fiber has been shown in research to help feed the “good” bacteria in our gut.
  • Corn isn’t a good source of nutrients – Corn contains a certain amount of vitamin B and C, as well as magnesium and potassium. Yellow corn is also a good source of antioxidants, which are good for eyes.
  •  You shouldn’t eat corn because it’s really high in sugar – You don’t stop having bananas just because you think they’re high in sugar. Then why should you do the same for corn? A cob of corn has around 6 to 8 grams of sugar, while a banana has about 15.

Milk Drinking Still a Mystery

The mutation for milk-drinking evolved independently in different parts of the world over the last 10,000 years as a result of strong natural selection, but why was it so advantageous?

Among the more momentous developments in human evolution was the ability to digest milk beyond early childhood.

Milk: Does It Really Do A Body Good?
Add it to the list of things that are bad for you: milk!
Mutations that enabled lifelong milk drinking appeared independently in several parts of the world over the last 7,500 years, according to growing evidence. And those genes spread rapidly. Today, about a third of adults around the world can drink milk without stomach problems, a trait known as lactase persistence.

But why was milk drinking so advantageous to humankind?

A new study debunks one leading theory: that milk provided a valuable source of vitamin D, which would’ve helped people absorb its calcium.

Newly analyzed human skeletons from an ancient site in Spain show that the milk-drinking gene spread just as rapidly in that sun-drenched climate as it did in other places, suggesting that milk must have been beneficial there for some reason other than its vitamin D content.

“Throughout the years, I have heard so many evolutionary hypotheses about lactase persistence because they are so fun to coin,” said Oddný Sverrisdóttir, an evolutionary biologist at the University of Uppsala in Sweden. “For decades now, people have hypothesized that it was because of lack of sunlight in the north of Europe that people would have had to supplement the lack of calcium and vitamin D by drinking milk.”

“Now, looking at this picture from Spain,” she said, “the calcium-assimilation hypothesis either didn’t affect the evolution of lactase persistence at all, or other forces were there as well.”

Sverrisdóttir has long been interested in how and why Europe’s early farmers began drinking milk, so she was excited when she got her hands on well-preserved samples of skeletal remains from eight people who lived in northeastern Spain about 5,000 years ago. That was well after the milk-drinking mutation had appeared in northern Europe, and she was eager to find out if those ancient Spaniards were drinking milk, too. So the first thing she did was test their DNA for lactase persistence.

“I thought at least one would have the mutation,” since so many of today’s Spanish adults can drink milk without health consequences, Sverrisdóttir said. “None did.”

To figure out whether the recent and rapid spread of lactase persistence in Spain was a fluke or if natural selection was at play, Sverrisdóttir and colleagues compared the mitochondrial DNA of modern Spaniards with the ancient samples. Mitochondrial DNA changes very slowly, making it ideal for tracing family trees over time.

And, the researchers report today in the journal Molecular Biology and Evolution, analyses showed that the ancient cave dwellers were indeed ancestors of people who live and frequently drink milk in Spain today.

Tummy `clock` tells us how much to eat

Scientists have found the first evidence that the nerves in the stomach act as a circadian clock, limiting food intake to specific times of the day. The discovery, by University of Adelaide researchers , could lead to new information about how the gut signals to our brains about when we’re full, and when to keep eating.

In the University’s Nerve-Gut Research Laboratory, Dr Stephen Kentish investigated how the nerves in the stomach respond to stretch, which occurs as a consequence of food intake, at three-hourly intervals across one day. “These nerves are responsible for letting the brain know how much food we have eaten and when to stop eating,” said Kentish, who is the lead author of the paper.

“What we’ve found is that the nerves in the gut are at their least sensitive at time periods associated with being awake. This means more food can be consumed before we feel full at times of high activity, when more energy is required,” Kentish added.

“However, with a change in the day-night cycle to a period associated with sleeping , the nerves in the stomach become more sensitive to stretch, signalling fullness to the brain quicker and thus limiting food intake.

“This variation repeats every 24 hours in a circadian manner, with the nerves acting as a clock to coordinate food intake with energy requirements ,” he said. So far this discovery has been made in lab studies, not in humans. “Our theory is that the same variations in nerve responses exist in human stomachs , with the gut nerves being less sensitive to fullness during the day and more sensitive at night,” he said.
