Consumption of Dairy Products Changed the Shape of Human Skull: Study

We all know milk makes our bones stronger. But a new study suggests that the consumption of milk and other dairy products did not make skulls of our ancestors stronger or bigger. Read on to know how!

  • According to a new study, change in Human skull structure could be due to the consumption of a specific diet
  • Researchers believe the practice of chewing altered face structures
  • Skull morphology also varies between people of different genders

New York, August 25, 2017: Do you belong to the category of people who read the label on every food item they purchase? Do you count your calories and keep an account of your daily calorie consumption? Are you the person who religiously reads articles on health and nutrition on the internet? Even if not, this article is going to take you by surprise. What if we tell you that an individual’s diet alters the construction of the human skull?

Having processed food that lacks several important nutrients exposes us to an increased risk of various medical problems like diabetes, hypertension, obesity, etc. However, recent studies have found that the diet you consume, particularly in your growing years, has a major impact on the development of your bones, jaws and even the face structure/human skull!

A team comprising of David Katz, a postdoctoral researcher at the University of Calgary, Professor Tim Weaver and statistician Mark Gote from the University of California-Davis accessed a collection of 559 crania and 534 lower jaws (skull bones) from different corners of the world that ranged from more than a two dozen population from the pre-industrial era. These bones were then studied to analyze the influence that the diet consumed had on the form, size and shape of the human skull during the time man shifted to consumption of agricultural products.

The research found that the advent of farming practices, especially the consumption of dairy products significantly affected the shape of human skull.

The researchers observed modest changes in human skull morphology for groups that were dependent on cereals, dairy, or a combination of the two. This effect was more evident in populations suspected to consume softer foods like cheese.

According to Katz, for the early farmers of the time, “milk did not make for bigger, stronger skull bones.”

Katz found that the primary difference between the skulls of a hunter-gatherer and that of a farmer “are where we would expect to find them, and change in ways we might expect them to.” This he believes, could happen if the demand of chewing decreased within the farming groups.

According to the study, different foods determined how often or how hard one had to chew. The constant movement of the bones in order to properly chew food is what is believed to have altered the shape.

Chewing on hard foods activates bone cells which promote the growth of strong and big jaws. Alternatively, consumption of softer foods like dairy products led to people having smaller jaws with tooth-crowding.

Apart from dietary consumption, the researches claim human skull morphology was also altered by the gender of the people, or between individuals who consumed the same diet but were from different populations.

The study has been published in the journal Proceedings of the National Academy of Sciences.

Poor Dental Health can Lead to Obesity in Children

  • Worried about your child’s obesity problems? It’s high time you curbed his love for sugary drinks and junk food. A little focus on dental care may also prevent your child gaining excess weight, says a new study.

The study found a direct relationship between poor dental health leading to a rise in BMI (Body Mass Index) and extra body fat.

“Weight can be a sensitive subject, but if you talk about eating behaviors alongside dental health, you are looking at the issue from a different angle,” said Louise Arvidsson, a doctoral student at the University of Gothenburg in Sweden.

“The question is whether a healthy diet can have the effect also in young children. There has been a lot of focus on physical activity and mental health in children, but diet is an increasingly recognized aspect.”

The researchers reviewed the eating behavior, body fat and dental health of 271 small children. The height, weight and food intake of the children were kept under observation for one day and then checked for the prevalence of cariogenic microorganisms in saliva.

The results found that the children who had a higher amount of carries bacteria also had higher BMI and worse eating habits.

The children were suggested to consume whole grain products, 400-500 grams of fruit and vegetables per day, fish two to three times a week and a low intake of sugar and saturated fat.

Arvidsson mentioned in the thesis, conducted at the University’s Sahlgrenska Academy, that with good food comes increased self-esteem, better relationships with friends and fewer emotional problems

Rather, parents who try to change the regime of their children by asking them to eat less during childhood can see serious repercussions of overweight problems in later life.(IANS)

  • Want to live longer? Charge up on your cup of coffee. According to a study, caffeine consumption may prolong the lifespan of patients with chronic kidney disease (CKD).

Drinking coffee can Reduce mortality 

The findings showed a dose-dependent inverse association between caffeine and all-cause mortality.

People who had the highest intake of coffee had 24 percent lower risks of dying, while those in the second, third quartile of caffeine consumption had 12 percent and 22 percent lower risk.

“These results suggest that advising patients with CKD to drink more caffeine may reduce their mortality. This would represent a simple, clinically beneficial, and inexpensive option,” said Miguel Bigotte Vieira from Centro Hospitalar Lisboa Norte, in Portugal.

However, “this benefit should ideally be confirmed in a randomised clinical trial”, Vieira added.

For the study, the team examined the association of caffeine consumption with mortality among 2328 patients with CKD. The results will be presented at the ongoing ASN Kidney Week 2017 in New Orleans.

Moreover, this observational study cannot prove that drinking coffee reduces the risk of death in patients with CKD, but only suggests the possibility of such a protective effect, Vieira stressed.

Drinking coffee can also reduce diabetes risk, revealed a reported in the American Chemical Society Journal of Natural Products.(IANS)

Health Benefits of eating more Whole Grains

Having a whole grain diet helps lose weight, as compared to refined grains -- rich in starch, gluten and devoid of natural fiber.

  • Regularly consuming whole grain foods such as barley, brown rice, millet, oatmeal and rye may help lose weight
  • It also decreases the risk of heart disease and diabetes, a study has claimed.

Why should you eat more whole grains? Here is all you need to know

The findings showed that study participants who ate whole grains had less inflammation, particularly in overweight people, which increases the risk of developing Type 2 diabetes.

Further, participants were also found to eat less when whole grain products were on the menu because whole grain consumption causes satiety.

Importantly, having a whole grain diet helps lose weight, as compared to refined grains — rich in starch, gluten and devoid of natural fiber.

“Our analysis confirmed that there is a sound scientific basis for the dietary recommendation to eat whole grains. This may particularly apply to people who are at increased risk of developing cardiovascular disease or Type 2 diabetes,” said Tine Rask Licht, professor at the Technical University of Denmark.

Additionally, the researchers used DNA sequencing to analyze stool samples from the participants in order to examine whether the different diet types affected the participants’ gut bacteria composition.

Overall, the analysis did not show major effects of the dietary grain products on the composition of the lose weight.

“However, even though the analysis did not reveal significant changes in the average gut microbiota after whole grain consumption, it may well be that the individual components of our gut microbes has an impact on the individual reaction of our body to dietary whole grains,” Licht explained.

For the study, described in the journal Gut, the team included adults at risk of developing cardiovascular disease or Type 2 diabetes. The participants were divided randomly into two groups, with whole grain diet and refined varieties for eight weeks.(IANS)
