If you want to live longer, reduce levels of inflammation throughout your body and delay the onset of age-related diseases — eat less food, say researchers.
According to a study, published in the journal Cell, researchers from the US and China provided the most detailed report of the cellular effects of a calorie-restricted diet in rats, say researchers.
According to a study, published in the journal Cell, researchers from the US and China provided the most detailed report of the cellular effects of a calorie-restricted diet in rats.
While the benefits of caloric restriction have long been known, the new results show how this restriction can protect against aging in cellular pathways.
“We already knew that calorie restriction increases life span, but now we’ve shown all the changes that occur at a single-cell level to cause that,” said study senior author Juan Carlos Izpisua Belmonte from the Salk Institute in the US
“This gives us targets that we may eventually be able to act on with drugs to treat aging in humans,” Belmonte added. For the findings, the research team compared rats who ate 30 per cent fewer calories with rats on normal diets.
The diet of animals in the age group of 18-27 months was controlled. (In humans, this would be roughly equivalent to someone following a calorie-restricted diet from the age of 50 to 70.) The research team isolated and analysed a total of 168,703 cells from 40 cell types in the 56 rats from starting as well as during the conclusion of the diet. The cells came from fat tissues, liver, kidney, aorta, skin, bone marrow, brain and muscle.
In each isolated cell, the researchers used single-cell genetic-sequencing technology to measure the activity levels of genes. They also looked at the overall composition of cell types within any given tissue. Then, they compared old and young mice on each diet.
Many of the changes that occurred as rats on the normal diet grew older didn’t occur in rats on a restricted diet; even in old age, many of the tissues and cells of animals on the diet closely resembled those of young rats.
Overall, 57 per cent of the age-related changes in cell composition seen in the tissues of rats on a normal diet were not present in the rats on the calorie restricted diet, the study said. “This approach not only told us the effect of calorie restriction on these cell types, but also provided the most complete and detailed study of what happens at a single-cell level during aging,” said study researcher Guang-Hui Liu from Chinese Academy of Sciences in China. According to the study, some of the cells and genes most affected by the diet related to immunity, inflammation and lipid metabolism.
The number of immune cells in nearly every tissue studied dramatically increased as control rats aged but was not affected by age in rats with restricted calories.
In brown adipose tissue–one type of fat tissue–a calorie-restricted diet reverted the expression levels of many anti-inflammatory genes to those seen in young animals, the research said. (IANS)

The author who named the book after her twin sons -- Puhor and Niyor -- is a parent who has seen and heard the tales of ridicule and discrimination suffered by many in India and beyond. She says the book is an artistic illustration for kids that details how different families can live and coexist. Whether it's children with two dads or two moms, children with a single dad or single mom, and even multiracial family units, Borthakur's book teaches love, understanding, and compassion towards unconventional families.
Beyond race, gender, color, and ethnicity which have formed the bases for discrimination since the beginning of time, this book aims to bring to light a largely ignored issue. For so long, single parents have been treated like a taboo without any attempt to understand their situations; no one really cares how or why one's marriage ended but just wants to treat single parents as villains simply for choosing happiness and loving their children.
Homosexual parents, a relatively new family system, is another form that has suffered hate and discrimination for many years. Pritisha emphasizes the need to understand that diversity in people and family is what makes the world beautiful and colourful. 'Puhor and Niyor's Mural of Family Stories' is a firm but compassionate statement against all forms of discrimination on the bases of sexual identity, gender, race, and even differences in background
The Guwahati-born author says, "With this book, I'm not trying to take away the job of parents in forming habits, I simply want to do my part as a parent. It is important that we impart the right values in our kids in a bid to build a better, more inclusive and tolerant global society that is fair to everyone." The author's first attempt at a book was an Assamese poetry 'Anubhav', published in 2010.
Set to be published under the label of Author's Channel, the book is like an adventure; a journey into uncharted territories, untouched subjects and matters long ignored. In her words. "The book takes a critical stand in defense of people in society who have had to undergo severe emotional torture for no cause of theirs. It is a terrible conception to think such people any less of a human just for being different," says publisher Aruna Naidu. By September 30, this title, priced at Rs 299, will be available online and in offline bookstores. (IANS/ MBI)
Rajesh U Pandya, Managing Director, KAI India, gives easy and completely doable tips to follow at home:
* Refrain from harsh soaps: You should be mindful of the soap you are using to wash your hands. Your soap can have a moisturizing element in it like aloe vera or shea butter. Ensure that you're washing your hands with normal water as hot water can make your hand's skin dry and scaly.

* Be aware of nail or cuticle inflammation or redness: If there are any signs of infection, disinfect the skin as soon as possible with an anti-bacterial or anti-fungal ointment.
