Add nuts to your diet for sake of health, longevity

December 15, 2013

NutsDec 15: Nuts to you! No, that’s not an insult. It’s a recommendation to add nuts to your diet for the sake of health and longevity.

Consistent evidence for the health benefits of nuts has been accumulating since the early 1990s. Frequent nut consumption has been linked to a reduced risk of major chronic diseases, including heart and blood vessel disorders and Type 2 diabetes.

The newest and most convincing findings, reported last month in The New England Journal of Medicine, come from the Nurses’ Health Study and the Health Professionals Follow-Up Study, which together have followed nearly 119,000 women and men for decades. Both studies repeatedly recorded what the participants ate and analysed their diets in relation to the causes of death among the 27,429 people who died since the studies began.

The more often nuts were consumed, the less likely participants were to die of cancer, heart disease and respiratory disease, and not because nut eaters succumbed to other diseases. Their death rate from any cause was lower during the years they were followed. (The nuts in question were pistachios, almonds, Brazil nuts, cashews, hazelnuts, macadamias, pecans, pine nuts, peanuts and walnuts.)

I know what you’re thinking: Aren’t nuts fattening? Yes, an ounce of nuts has 160 to 200 calories, nearly 80 per cent from fat.

But in study after study, the more often people ate nuts, the leaner they tended to be.

For example, in a Mediterranean study that tracked the effect of nut consumption on weight gain over the course of 28 months, frequent nut consumers gained less weight than those who never ate nuts, and were 43 per cent less likely to become overweight or obese.

How is that possible? First, nuts may be taking the place of other high-calorie snacks, like chips, cookies and candy. And nut eaters may be less likely to snack, period; the fat, fiber and protein in nuts suppresses hunger between meals.

Second, the body may treat calories from nuts differently from those in other high-carbohydrate foods. Third, nut eaters may pursue a healthier lifestyle and burn more calories through exercise.

And not just tree nuts. The new study found that peanuts were also linked to a reduced death rate and lower risk of chronic disease.

Thus, all nuts are powerhouses of biologically active substances, most of which are known to protect and promote health. Penny M Kris-Etherton, a professor of nutrition at Penn State who has studied the effects of nuts on heart disease, describes them as “complex plant foods that are not only rich sources of unsaturated fat but also contain several nonfat constituents”, including protein, fibre, plant sterols that can lower cholesterol, and micronutrients like copper and magnesium.

Every one of these substances has been shown to ward off one disease or another. The fat content of nuts alone could account for their ability to support heart health. Nuts have less cholesterol-raising saturated fat than olive oil. On average, 62 per cent of the fat in nuts is monounsaturated, the kind that supports healthy levels of protective HDL cholesterol and does not raise blood levels of harmful LDL cholesterol.

Most nuts, and especially almonds, are good sources of vitamin E, an antioxidant. The nurses’ study has linked tree nuts to a reduced risk of pancreatic cancer. In both the nurses’ and health professionals’ studies, eating nuts more than five times a week was associated with a 25 per cent to 30 per cent lower risk of needing gallbladder surgery.

While coughing, fever and difficulty in breathing are common symptoms of COVID-19, a new case study has found that pink eye is also a reason to be tested for the disease.

The study, published in the Canadian Journal of Ophthalmology, determined that conjunctivitis and keratoconjunctivitis can also be primary symptoms of COVID-19.

The researchers noted that in March, a 29-year-old woman arrived at the Royal Alexandra Hospital's Eye Institute of Alberta with a severe case of conjunctivitis and minimal respiratory symptoms.

After the patient had undergone several days of treatment with little improvement -- and after it had been determined that the woman had recently returned home from Asia -- a resident ordered a COVID-19 test.

The test came back positive, according to the researchers.

"What is interesting in this case, and perhaps very different to how it had been recognised at that specific time, was that the main presentation of the illness was not a respiratory symptom. It was the eye," said Carlos Solarte, an assistant professor at the University of Alberta in Canada.

"There was no fever and no cough, so we weren't led to suspect COVID-19 at the beginning. We didn't know it could present primarily with the eye and not with the lungs," Solarte said.

Academic studies at the outset of the pandemic identified conjunctivitis as a secondary symptoms in about 10 to 15 per cent of COVID-19 cases, he said.

Since then, scientists have gained greater knowledge of how the virus can transmit through and affect the body's mucous membrane system, of which the conjunctiva -- the clear, thin membrane that covers the front surface of the eye -- is an extension.

While the finding provides important new health information for the public, it also makes eye exams more complicated for ophthalmologists and staff, the researchers noted.

"The patient in this case eventually recovered well without any issues. But several of the residents and staff who were in close contact with the patient had to be under quarantine," said Solarte.

"Fortunately, none who were involved in her care also tested positive," he said.

Patients coming into an eye clinic with conjunctivitis and keratoconjunctivitis are now treated as potential cases of COVID-19 and extra precautions are taken by staff, according to the researchers.

Washington, Jun 20: Pregnant and postpartum women are usually at a high risk of depression and anxiety - one in seven women struggle with symptoms in the perinatal period and the coronavirus pandemic is exacerbating those struggles according to a recent study.

The study was published in Frontiers in Global Women's Health, which found that the likelihood of maternal depression and anxiety has substantially increased during the health crisis.

"The social and physical isolation measures that are critically needed to reduce the spread of the virus are taking a toll on the physical and mental health of many of us," said Dr. Margie Davenport of the University of Alberta, Canada, who co-authored the study.

For new moms, those stresses come with side effects.

"We know that experiencing depression and anxiety during pregnancy and the postpartum period can have detrimental effects on the mental and physical health of both mother and baby that can persist for years," said Davenport.

Such effects can include premature delivery, reduced mother-infant bonding, and developmental delays in infants.

The study surveyed 900 women - 520 of whom were pregnant and 380 of whom had given birth in the past year - and asked about their depression and anxiety symptoms before and during the pandemic.

Before the pandemic began, 29 percent of those women experienced moderate to high anxiety symptoms, and 15 percent experienced depressive symptoms. During the pandemic, those numbers increased - 72 percent experienced anxiety and 41percent experienced depression.

Because lockdown measures have affected daily routines and access to gyms, researchers also asked women whether their exercise habits had changed. Of the women surveyed, 64 percent reduced their physical activity since the pandemic began, while 15 percent increased and 21 percent experienced no change.

Exercise is a known way to ease depression symptoms, so limited physical activity may result in an uptick in depressive symptoms. Indeed, the study found that women who engaged in at least 150 minutes of moderate physical activity a week had significantly lower symptoms of depression and anxiety.

The findings are somewhat limited given the fact that researchers could not survey women before the pandemic began (since they could not know a pandemic would occur). The women surveyed could only offer their pre-pandemic symptoms in hindsight.

Also, while the researchers asked women about their symptoms using validated measures, only mental health care professionals can validly diagnose an individual with depression or anxiety.

The study was specifically interested in the impact of COVID-19 on new moms, but Davenport says maternal mental health is a critical issue no matter the time.

"Even when we are not in a global pandemic, many pregnant and postpartum women frequently feel isolated whether due to being hospitalized, not having family or friends around or other reasons," she said.

"It is critical to increase awareness of the impact of social (and physical) isolation on the mental health of pregnant and postpartum women," Davenport added.

Increased awareness makes diagnosis and treatment - the ultimate goal - more likely.

New Delhi, Mar 27: The Centre has restricted sale and distribution of "hydroxychloroquine" declaring it as an essential drug to treat the COVID-19 patients and meet the requirements of emergency arising due to the pandemic.

The Ministry of Health and Family Welfare on Thursday made the announcement making it clear that the order "shall come into force on the date of its publication in the official Gazette".

In the order, the government declared that the Central government is "satisfied that the drug hydroxychloroquine is essential to meet the requirements of emergency arising due to pandemic COVID-19 and in the public interest, it is necessary and expedient to regulate and restrict the sale and distribution of the drug 'hydroxychloroquine' and preparation based thereon for preventing their misuse".

"Now, therefore, in exercise of the powers conferred by Section 26B of the Drugs and Cosmetics Act, 1940 (23 of 1940), the Central government hereby directs that sale by retail of any preparation containing the drug Hydroxychloroquine shall be in accordance with the conditions for sale of drugs specified in Schedule H1 to the Drugs and Cosmetics Rules, 1945."

The order came at a time when the novel coronavirus claimed 16 lives and infected over 600 people across India.

The announcement regarding ban of sale and distribution of the drug was made by the government earlier but it issued an official Gazette notification on Thursday signalling that hydroxychloroquine -- an anti-Malaria drug -- will work as a medicine for treating coronavirus infected patients as well.

Recently, the national task force for COVID-19 constituted by Indian Council for Medical Research (ICMR) has recommended hydroxy-chloroquine as a preventive medication.
