“Walnuts” the new brain food for stressed university students

Stressed university students might want to add walnuts to their daily diet in the weeks leading up to their next exam.

A new  clinical trial of undergraduate students during their university studies has shown positive effects of walnut consumption on self-reported measures of mental health and biomarkers of general health.

The University of South Australia study, published in the journal Nutrients, also suggests that walnuts may counteract the effects of academic stress on the gut microbiota during periods of stress, especially in females.

Lead researchers, PhD student Mauritz Herselman and Associate Professor Larisa Bobrovskaya, say the results add to the growing body of evidence linking walnuts with improved brain and gut health.

“Students experience academic stress throughout their studies, which has a negative effect on their mental health, and they are particularly vulnerable during exam periods,” Herselman says.

Eighty undergraduate students split into treatment and control groups were clinically assessed in three intervals, at the beginning of a 13-week university semester, during the examination period and two weeks after the examination period. Those in the treatment group were given walnuts to consume daily for 16 weeks over these three intervals.

“We found that those who consumed about half a cup of walnuts every day showed improvements in self-reported mental health indicators.  Walnut consumers also showed improved metabolic biomarkers and overall sleep quality in the longer term.”

Students in the control group reported increased stress and depression levels in the leadup to exams but those in the treatment group did not. The walnut consumers also reported a significant drop in feelings associated with depression between the first and final visits, compared to the controls.

Previous research has shown that walnuts are full of omega-3 fatty acids, antioxidants, as well as melatonin (sleep inducing hormone), polyphenols, folate and vitamin E, all of which promote a healthy brain and gut.

“The World Health Organization has recently stated that at least 75 per cent of mental health disorders affect people under the age of 24 years, making undergraduate students particularly vulnerable to mental health problems,” Herselman says.

Assoc Prof Larisa Bobrovskaya says mental health disorders are common in university students and can adversely affect students’ academic performance and long-term physical health.

“We have shown that consuming walnuts during stressful periods can improve mental health and general wellbeing in university students, as well as being a healthy and delicious snack and a versatile ingredient in many recipes, to fight some negative effects of academic stress,” Assoc Prof Bobrovskaya says.

“Due to fewer numbers of males in the study, more research is needed to establish sex-dependent effects of walnuts and academic stress in university students. It’s also possible that a placebo effect might have come into play as this was not a blind study.”

GST Highest in World, Arbitrary and Bizarre, Says Cong Leader Surjewala

Unlike what Congress proposed as a simple three-tier GST capping at 18%, the BJP-led NDA government has made it 4-slab and added 28% slab imposing one of the worst taxation system in the world, said Congress leader Randeep Singh Surjewala.

Besides the Goods and Services Tax (GST), the cess included, some products will be as costlier as 43% more than the existing prices, he said. The cascading effect will be another standstill in economic growth as it would affect the common man and daily purchasing power of many people, he said.

While the livelihood of shopkeepers, traders, micro and small businesses is at stake, the new tax regime defeats the very purpose of simplifying the tax structure.  Addressing a Traders Sammelan of ‘Vyapar Bachao-Dukandar Bachao’ protest in Haryana, he said, “The GST in its current form will be a blow to the farmers, textile sector, small and medium businesses. It will lead to run away inflation for all goods of mass consumption.”

He revealed that the original proposal made by the UPA government was simple, transparent and not at all complicated. But the new BJP framed GST requires 37 returns to be filed by every taxpayer per year. “In case, a taxpayer is doing business in all 36 states/UTs, it will be 1,332 returns, which is shocking,” he revealed.

The GST is against the basic needs of common man — roti, kapda aur makaan — as all these sectors are set for shocking rise in costs, he said. Giving examples, he said, “daily use items” like shampoos, deodrant attract 28 per cent, ACs/TVs/washing machines too attract 28%, furniture 28 %, computers/printers 28% and even small cars attract 28% and questioned the rationale in attacking the middle class which consumes most of these items.

He pointed out that even sanitary napkins, which are usually kept outside the tax regimes in many advanced and even poorer countries have been put under 12% tax regime on par with shoes and footwear. Even dialysis/blood test/X-ray/ultrasound etc. come under the same category, smacking the irrational treatment of medical services in the country, which may increase the medical bills for the common man.

Daily food items like tea/coffee/butter/biscuit/ curd/sweets/juices attract 12 pc to 28 pc, revealing the mindless aggressive attitude of the policy makers and tax administrators.

“Does it make sense to tax mineral water at 18 per cent even when caviar and prawns are taxed at 12 per cent or even when exotic imported fruits and vegetables are taxed at 0 per cent,” he asked.

Giving an example of taxing almonds and dry fruits at 12 per cent and cashew nuts at 5 per cent, he questioned the rationale behind such decision-making. It is everybody’s knowledge that almonds and dry fruits are good for health while cashew is fatty food and not advised for good health.

He questioned tax on man-made fiber and yarn, dyeing and printing and embroidery at 18% while the end product fabric is only 5 per cent, which means the service sector in textile would be hit badly and many may loose jobs.

While Indian farmer can’t compete with global farmer as there is a massive shortage of cold storage units in the country coupled with high indebtedness and suicides among the farmers, the government has imposed 18% tax on construction of cold storage units, which is more harmful to India and may increase imports.

This is what “Modi government’s method of governance: long on talks and short on delivery,” he told the protesters.
