Ladies, please take note. Consuming a high-fibre diet may reduce the risk of preeclampsia during pregnancy, researchers have found.

“Simple recommendation to ‘eat real food, mostly plants and not too much’ might be the most effective primary prevention strategy for some of the most serious conditions of our time.

“The mother’s gut bacteria and diet appear to be crucial to promoting healthy pregnancy,” said study lead author Ralph Nanan, Professor at the University of Sydney.

The study, published in the journal Nature Communications, showed that pregnancy outcomes and infant immunity are linked to gut bacteria.

Plant-based fibre is broken down in the gut by bacteria into factors that influence the immune system. The research team investigated the role of these metabolic products of gut bacteria during pregnancy.

The researchers found that in humans, reduced levels of acetate, which is mainly produced by fibre fermentation in the gut, is associated with the common and serious pregnancy-related condition preeclampsia.

Preeclampsia occurs in up to 10 per cent of pregnancies and is characterized by high blood pressure, protein in the urine and severe swelling in the mother’s body.

It also interferes with the child’s immune development whilst in the womb, with some evidence suggesting a link to higher rates of allergies and autoimmune diseases later in life.

The study found that preeclampsia affected the development of an important foetal immune organ – the thymus – which sits just behind the breastbone.

Foetuses in preeclamptic pregnancies were found to have a much smaller thymus than children from healthy pregnancies.

The cells the thymus normally generates — called ‘T’ cells, and specifically those associated with the prevention of allergies and autoimmune conditions such as diabetes — also remained lower in infants after preeclampsia, even four years after delivery.

The mechanisms of acetate on the developing foetal immune system were further examined in separate experiments involving mice that showed acetate was central in driving foetal thymus and ‘T’ cell development.

The results showed that promoting specific metabolic products of gut bacteria during pregnancy might be an effective way to maintain a healthy pregnancy and to prevent allergies and autoimmune conditions later in life. (IANS)

The unhealthy habits of modern-day living with a diet high in calories may cause brain health to deteriorate faster, according to an Australian study published on Thursday.

Compared to 50 years ago, people currently consume an average of around 650 extra kilocalories each day, which is equivalent to a fast-food meal of a burger, fries and a soft drink, said the study’s lead author, Nicolas Cherbuin of the Australian National University (ANU).

“People are eating away at their brain with a really bad fast-food diet and little-to-no exercise,” Cherbuin, who is a professor at the ANU Centre for Research on Ageing, Health and Wellbeing, said in a statement.

“We’ve found strong evidence that people’s unhealthy eating habits and lack of exercise for sustained periods of time puts them at serious risk of developing type 2 diabetes and significant declines in brain function, such as dementia and brain shrinkage,” he added.

According to the study, 30 per cent of the global adult population is either overweight or obese, and over 10 per cent of the world’s adult population will have type 2 diabetes by 2030, reports Efe news.

The expert pointed out that while the link between this type of diabetes and the deterioration of brain function has long been known, research shows that the loss of neurons and their functions begins “much, much earlier”, indicating “a clear association between this brain deterioration and unhealthy lifestyle choices”.

“People eating too much of the wrong kind of food, particularly fast food, is the other big worry,” according to the expert, who warned that advice for people to reduce their risk of brain problems, including their risk of dementia, begin too late, mostly when people are in their 60s or later.

“The damage done is pretty much irreversible once a person reaches midlife, so we urge everyone to eat healthy and get in shape as early as possible – preferably in childhood but certainly by early adulthood,” Cherbuin said. (IANS)
