I’ve got some interesting stuff for this 9th edition of around the web. To new readers whose recently subscribed to my newsletter: Around the web is a set of posts where I highlight some of the latest research, videos, and articles on nutrition, exercise, microbes, and other aspects of human health. Don’t hesitate to post a link in the comment section of my blog posts if you find good articles online.
Okay, let’s get to it…
“A human being is more and more perceived as a super-organism consisting of a eukaryotic and a prokaryotic part”
Since there are few journalists, authors, and bloggers who use the term Superorganism to describe the human body, most people haven’t really encountered this idea before they stumble upon my blog. However, the word superorganism is sometimes used in the scientific literature to describe the expanding view of the human body as an ecosystem made up of human cells, bacteria, viruses, fungi, and other organisms. In a new scientific article, researchers discuss the essential role of the microbiome in regulating the immune system of the human superorganism.
2-year randomized trial shows that The Paleo Diet is superior to a diet based on the official dietary recommendations
Several studies have previously shown that a contemporary paleo diet is superior to other healthy diets such as The Mediterranean Diet for fat loss and health, but no long-term trials have been published until now. In this recent randomized study, obese postmenopausal women were divided into two groups and instructed to eat according to a paleo diet or a diet based on the Nordic Nutrition Recommendations. The results after 2 years show that the paleolithic diet has greater beneficial effects on fat mass, abdominal obesity, and triglyceride levels. For those of you who’ve read my posts on weight loss, this shouldn’t come as a big surprise.
While I definitely see the benefits of studying the ancestral human diet, I’m not convinced that properly prepared legumes, fermented dairy, cacao, potatoes, wine, and some other foods unknown to the paleolithic man can’t be a part of a healthy diet. However, I do recommend that people eliminate or reduce their consumption of cereal grains.
So, while you don’t have to emulate the foodways of our stone age ancestors to be healthy, the paleo diet provides a template for good nutrition in the 21st century.
Food packaging chemicals may be harmful to human health over long term
The synthetic chemicals used in the packaging, storage, and processing of foodstuffs might be harmful to human health over the long term, warn environmental scientists. This is because most of these substances are not inert and can leach into the foods we eat, they say. Despite the fact that some of these chemicals are regulated, people who eat packaged or processed foods are likely to be chronically exposed to low levels of these substances throughout their lives. And far too little is known about their long term impact. From Sciencedaily.com
Cavities are contagious
Since bacteria can be transferred from the microbiome of one person to another, health is contagious! In a recent study, researchers found that “mothers with cavities can transmit caries-producing oral bacteria to their babies when they clean pacifiers by sticking them in their own mouths or by sharing spoons”. Microbes that live in your mouth are easily transferred to other people (e.g., kissing, shared food and cutlery), so make sure you take care of your oral microbiome, not just for your own benefit, but also for your family’s and friends’ sake.
WE ARE NOT ALONE: How the Human “Planet” Is Colonized and a Gut Microbime Is Built
I stumbled upon a good video discussing the human microbiome. The video provided by YourekaScience focuses on the gut microbiome and its role in health and disease.
