Eating nuts may boost fetal brain development
A new study finds such kids excel in all cognitive areas.
- A Spanish study finds that nuts consumed early in pregnancy boost babies' cognitive strength.
- Eating walnuts, almonds, peanuts, pine nuts and/or hazelnuts early in pregnancy can make a big difference.
- For those without allergies, nuts are good food.
While the medical community — and parents — continue to deal with the 1 in 5 kids who suffer from a peanut allergy, there's some news about a very different, and beneficial, role such nuts can play in the diet of expecting mothers. A study from Barcelona Institute for Global Health (ISGlobal) and published in the European Journal of Epidemiology has found that eating nuts during the first trimester of pregnancy can boost a baby's intelligence.

The Spanish study included over 2,200 mother/child pairs enrolled in proyecto INMA. Questionnaires tracked the nut intake of these mothers from Asturias, Guipuzcoa, Sabadell and Valencia during their first and third trimesters. Walnuts, almonds, peanuts, pine nuts and hazelnuts were the specific nuts ingested.
The Spanish Society of Community Nutrition recommends an average weekly nut consumption of between three and seven 30g servings a week. (Thirty grams is about 36 cocktail peanuts.) The women in the study had less than that amount, with a weekly average of just under three servings. Given the study's finding, says ISGlobal researcher and first author Florence Gignac, "This makes us think that if the mothers consumed the recommended weekly average the benefits could be much greater."
The children in the study were given questionnaires at ages of 1.5, 5 and 8 years of age to assess their cognitive abilities. The kids whose mothers had eaten nuts in their first trimester got high scores in all three tested areas: cognitive function, attention capacity, and working memory. No similar effect was found for children of final trimester nut consumption.

The results suggest that nuts make their positive contribution to cognitive development primarily during the mothers' early weeks of pregnancy. Second study author Jordi Júlvez Calvo says, "While our study does not explain the causes of the difference between the first and third trimesters, the scientific literature speculates that the rhythm of fetal development varies throughout the pregnancy and that there are periods when development is particularly sensitive to maternal diet."
Timing aside, the finding is further evidence of a mother's nutrition as an important factor in fetal development, with long-term benefits. "We think," says Gignac, "that the beneficial effects observed might be due to the fact that the nuts provided high levels of folic acid and, in particular, essential fatty acids like omega-3 and omega-6. These components tend to accumulate in neural tissue, particularly in the frontal areas of the brain, which influence memory and executive functions."
Júlvez warns that, of course, this is just one study, and expectant mothers should exercise caution when devising their diet during pregnancy based on its finding. "In any case," he says, "as this is the first study to explore this effect, we must treat the findings with caution and work on reproducing them in the future with more cohort studies as well as randomized controlled trials."

Health officials in China reported that a man was infected with bubonic plague, the infectious disease that caused the Black Death.
- The case was reported in the city of Bayannur, which has issued a level-three plague prevention warning.
- Modern antibiotics can effectively treat bubonic plague, which spreads mainly by fleas.
- Chinese health officials are also monitoring a newly discovered type of swine flu that has the potential to develop into a pandemic virus.
Bacteria under microscope
needpix.com<p>Today, bubonic plague can be treated effectively with antibiotics.</p><p style="margin-left: 20px;">"Unlike in the 14th century, we now have an understanding of how this disease is transmitted," Dr. Shanthi Kappagoda, an infectious disease physician at Stanford Health Care, told <a href="https://www.healthline.com/health-news/seriously-dont-worry-about-the-plague#Heres-how-the-plague-spreads" target="_blank">Healthline</a>. "We know how to prevent it — avoid handling sick or dead animals in areas where there is transmission. We are also able to treat patients who are infected with effective antibiotics, and can give antibiotics to people who may have been exposed to the bacteria [and] prevent them [from] getting sick."</p>

Centers for Disease Control and Prevention<p>Still, hundreds of people develop bubonic plague every year. In the U.S., a handful of cases occur annually, particularly in New Mexico, Arizona and Colorado, <a href="https://www.cdc.gov/plague/faq/index.html" target="_blank">where habitats allow the bacteria to spread more easily among wild rodent populations</a>. But these cases are very rare, mainly because you need to be in close contact with rodents in order to get infected. And though plague can spread from human to human, this <a href="https://www.healthline.com/health-news/seriously-dont-worry-about-the-plague#Heres-how-the-plague-spreads" target="_blank">only occurs with pneumonic plague</a>, and transmission is also rare.</p>
A new swine flu in China<p>Last week, researchers in China also reported another public health concern: a new virus that has "all the essential hallmarks" of a pandemic virus.<br></p><p>In a paper published in the <a href="https://www.pnas.org/content/early/2020/06/23/1921186117" target="_blank">Proceedings of the National Academy of Sciences</a>, researchers say the virus was discovered in pigs in China, and it descended from the H1N1 virus, commonly called "swine flu." That virus was able to transmit from human to human, and it killed an estimated 151,700 to 575,400 people worldwide from 2009 to 2010, according to the Centers for Disease Control and Prevention.</p>There's no evidence showing that the new virus can spread from person to person. But the researchers did find that 10 percent of swine workers had been infected by the virus, called G4 reassortant EA H1N1. This level of infectivity raises concerns, because it "greatly enhances the opportunity for virus adaptation in humans and raises concerns for the possible generation of pandemic viruses," the researchers wrote.
SEAL training is the ultimate test of both mental and physical strength.
- The fact that U.S. Navy SEALs endure very rigorous training before entering the field is common knowledge, but just what happens at those facilities is less often discussed. In this video, former SEALs Brent Gleeson, David Goggins, and Eric Greitens (as well as authors Jesse Itzler and Jamie Wheal) talk about how the 18-month program is designed to build elite, disciplined operatives with immense mental toughness and resilience.
- Wheal dives into the cutting-edge technology and science that the navy uses to prepare these individuals. Itzler shares his experience meeting and briefly living with Goggins (who was also an Army Ranger) and the things he learned about pushing past perceived limits.
- Goggins dives into why you should leave your comfort zone, introduces the 40 percent rule, and explains why the biggest battle we all face is the one in our own minds. "Usually whatever's in front of you isn't as big as you make it out to be," says the SEAL turned motivational speaker. "We start to make these very small things enormous because we allow our minds to take control and go away from us. We have to regain control of our mind."
Is focusing solely on body mass index the best way for doctor to frame obesity?
- New guidelines published in the Canadian Medical Association Journal argue that obesity should be defined as a condition that involves high body mass index along with a corresponding physical or mental health condition.
- The guidelines note that classifying obesity by body mass index alone may lead to fat shaming or non-optimal treatments.
- The guidelines offer five steps for reframing the way doctors treat obesity.
