Roughly 21 million American adults report having had a major depressive episode in a year, as reported by the National Institute of Mental Health. That's 8.3% of the population, and a pretty staggering number which doesn't account for the many people who may experience what they consider "minor" depressive episodes, which are also challenging and life-affecting.
Treatment for any kind of depression, or anxiety for that matter, varies from person to person, and should always be directed by a trusted medical professional. But what if incorporating certain foods into your diet more often could help alleviate minor depression or anxiety symptoms, even just a little? Well, that's what one study set out to find out, and it honed in specifically on pistachios.

In complete transparency, the study in question was supported by the American Pistachio Growers, however it was published in the Journal of Food Science and Nutrition Research, and led to some pretty interesting findings on how the nut can affect emotional health.
Researchers looked at data from over 64,000 adults in the U.S. and found that people who ate pistachios had lower rates of anxiety and fewer problems with depression than those who didn't eat them.
Honing in on a specific demographic, study participants ages 60 and above who ate pistachios had 16% less anxiety, and younger adults (ages 20 - 59) had fewer depression-related issues. Overall, pistachio eaters were about half as likely to have minor depression.
"Pistachios are a rich source of bioactive nutrients, and our research suggests that modest consumption may play a meaningful role in supporting mental well-being," said Kristin Fulgoni, lead author and researcher at Nutrition Impact, LLC. "What we noticed is that even small amounts of pistachios—about an ounce a day—were linked to these benefits."More findings to ponder: Study participants who ate roughly two-ounches of pistachios at night for 12 weeks had more of what's considered "good" gut bacteria (including Roseburiaand Lachnospiraceae) that are known to produce a compound called butyrate. Though more research is needed, early studies suggest that butyrate may support gut and brain health.
Pistachio eaters also had lower levels of other not-so-great bacteria, that have been connected to cognitive decline, poor mood state and other brain health challenges in observational studies.
So is it worth adding pistachios to your diet? Well, that's up to you and your healthcare professional. But if you're already snacking on 'em, now you can certainly feel better about it.This Underrated Snack Might Be the Secret to Better Health, According to a New Study first appeared on Parade on Jun 27, 2025

How to protect yourself from ticks year-round
WASHINGTON -- Ticks can be active in any season and it's important to check for and remove the bloodsuckers as quickly as possible — especially after you've been outside hiking, gardening or enjoying nature. 'Humans are outside more in summer so we hear about more tick infections,' said Sam Telford, an infectious diseases expert at Tufts University. But he urges caution year-round because 'every season is tick season.' While tick populations vary a lot regionally, some Northeastern states including Maine, Massachusetts and Rhode Island are seeing 'above average' numbers of American dog ticks this year, said Telford. And New York state is seeing a higher number of reported deer tick bites this year than last year, said Saravanan Thangamani, who studies tick-borne diseases at SUNY Upstate Medical University. Ticks, like mosquitos, need to feed on blood. But instead of a quick prick, they are slow feeders – with hooked mouth parts that attach into the skin of deer, rabbits, dogs and people. There are many different species of ticks found globally and only some spread germs that can make people sick. A main worry is blacklegged ticks, also called deer ticks, which can spread Lyme disease. Once found mainly in New England and pockets of the Midwest, the ticks are now present over a wider range. A tick bite doesn't always lead to illness. 'If you remove a tick within 24 hours of attachment, it's fairly unlikely that you will get infected,' said Telford. Ticks are usually found low to the ground, in leaf litter or grassy areas. Check your clothing for ticks and do a full-body check including under the arms and behind ears, knees and hair. 'If you're out all day long, try to do a quick check for ticks every few hours,' said Bobbi Pritt at the Mayo Clinic. 'When you go back inside, take a shower. That will wash off any unattached ticks, and you're also more likely to spot any other ticks." Use tweezers to remove the tick and grasp it as close to the skin as possible to pull from the head. If you don't have them handy, you can also use your fingernails, the edge of a credit card or any semi-sharp object. The best approach is to minimize tick exposure altogether. Bug sprays containing ingredients such as DEET can be sprayed on exposed skin to ward off ticks and mosquitos, said Telford. Wear long sleeves and pants, and you can also spray clothing with repellents containing permethrin, a chemical similar to a natural ingredient in chrysanthemums that makes ticks avoid the flowers. Don't forget to pay attention to outdoor pets. Medications can prevent fleas and ticks from attaching to a dog's skin. But it's still a good idea to check the fur after being outside. 'Wherever pets can't easily groom themselves, that's where the ticks will be – on the ears, around the muzzle area, under the collar, between the toes,' said Thangamani. Dogs and cats roaming outdoors can also bring ticks into the house. 'If pets bring ticks in, a tick can live in the house for months until it finds its next blood meal,' which could be another household member, he said. After removing the tick, keep an eye on the skin around the bite. If a rash or flu-like symptoms appear within several days or weeks, see a doctor. The Centers for Disease Control and Prevention does not recommend tick testing because results may not be reliable. ___
