Winter Salad Recipe, Spotlight on Homemade Vinaigrettes, Prepping Greens, A New Benefit of Vitamin D, and Aerobics for Knee arthritis

Salads aren’t just for summer, and if one of your New Year’s resolutions is to eat more fruits and veggies, this winter greens recipe fits the bill. I’ve dressed it with a sweet-tart vinaigrette that you can use with a variety of foods for lighter eating. I’m also sharing two new important findings: how vitamin D can help people avoid a second heart attack and a surprising way to manage knee arthritis.

Winter Salad

Using sweet and tart vinegars adds complexity to this vinaigrette, which is a delicious foil for the slightly bitter greens and sweet pears.
Ingredients

For Vinaigrette:
- 1 tablespoon red wine vinegar, such as Austrian Red Wine Vinegar
- 1 tablespoon balsamic vinegar of Modena, such as Condimento Barili Exclusivi
- 1/2 tablespoon Dijon mustard
- 1/2 tablespoon honey
- 1/4 teaspoon coarse sea salt, plus more to taste
- 1/2 garlic clove, minced
- 1/3 cup extra virgin olive oil
- Freshly ground black pepper to taste
For the Salad:
- 1/2 cup hazelnuts or walnut halves
- 4 to 6 cups baby spinach, baby kale, escarole, or other winter greens, rinsed and dried
- 2 ripe pears, cored and thinly sliced
- Block of Parmigiano-Reggiano or 2 ounces mild blue cheese
Directions

Step 1

Make the vinaigrette: In a medium mixing bowl, whisk together the vinegars, mustard, honey, salt, and garlic. Gradually whisk in the olive oil until the dressing is emulsified. Season to taste with pepper and more salt, if desired.

Step 2

Make the salad: Heat a small sauté pan. When hot, add the nuts and toast for 2 minutes until they become fragrant, tossing frequently; set aside.

Step 3

Divide the greens among 4 salad plates and top with equal amounts of pear slices and nuts. If using Parmigiano-Reggiano, use a cheese plane to make long shavings over each salad. If using blue cheese, crumble it. Drizzle a spoonful of vinaigrette over each salad and pass the rest on the side.

Healthy Ingredient Spotlight

Homemade Vinaigrettes

It’s no secret that most bottled dressings are loaded with sugar, artificial ingredients, and poor- quality oil. On the other hand, it’s so easy to make your own with just a few quality ingredients. Vinaigrettes can be made with a whisk, but using a blender or mini food processor can make fast work of it, especially if some ingredients need to be chopped or minced. As a general rule, you can pulse all the ingredients except the olive oil for a few seconds—let the machine mince any herbs, garlic, or shallots for you. Then with the machine still running, slowly add the olive oil through the feed tube until the vinaigrette is emulsified. Vinaigrette will keep for up to a week in the fridge; shake well or whisk as needed before using.

Quick Kitchen Nugget

Prepping Greens

To maximize taste when making salads, prep your greens by rinsing and drying them in a salad spinner or with an absorbent kitchen towel—dressing coats them better when they’re dry and won’t be diluted by water clinging to the leaves. Rather than simply pouring vinaigrette over your salad, mix it in with two forks or tongs to really dress the greens. Also, keep in mind that vinaigrettes aren’t just for salads—drizzle them over roasted vegetables, grains, and cold meats.

A New Benefit of Vitamin D

In a large randomized clinical trial, researchers from Intermountain Health in Salt Lake City found that managing the vitamin D levels of people who experienced a heart attack through a “target-to-treat” approach, with blood levels monitored and dosages adjusted to reach an optimal range, cut the likelihood of a second heart attack by 50%. The findings were presented on Nov. 9 at the 2025 American Heart Association Scientific Sessions in New Orleans.

According to researchers, the results carry global importance, as between one-half and two-thirds of people worldwide have low levels of vitamin D. In the past, most individuals received sufficient vitamin D through sunlight exposure. Today, with lifestyle changes and medical advice aimed at reducing skin cancer risk, people spend less time in the sun and must rely more on dietary supplements such as vitamin D₃ to maintain healthy levels.

Low vitamin D levels have long been linked to poor cardiovascular outcomes in observational studies. However, earlier clinical trials that provided standard supplementation doses failed to show measurable reductions in heart disease risk. Intermountain scientists wanted to test a different idea: Rather than giving everyone the same dose, what if supplementation was adjusted to reach a specific healthy vitamin D level?

“Previous studies just gave patients supplementation without regularly checking blood levels of vitamin D to determine what supplementation achieved,” said Heidi May, PhD, cardiovascular epidemiologist at Intermountain and the study’s principal investigator. “With more-targeted treatment, when we checked exactly how supplementation was working and made adjustments, we found that patients had their risk of another heart attack cut in half.”

The Intermountain study, called the TARGET-D trial, ran from April 2017 to May 2023 and included 630 patients who had suffered a heart attack within a month of enrolling. Participants were followed until March 2025 to monitor cardiovascular outcomes.

Patients were randomly assigned to one of two groups: One received no vitamin D management and the other underwent active, targeted vitamin D₃ treatment. The goal for the treatment group was to raise blood levels of vitamin D to above 40 nanograms per milliliter (ng/mL). At the start, 85% of participants had blood levels of vitamin D below that threshold. More than half of the patients receiving targeted therapy required an initial dose of 5,000 international units (IUs) of vitamin D₃ compared to typical supplement recommendations of 600-800 IUs.

Blood levels of vitamin D were checked annually for those maintaining healthy levels. Patients with lower levels were tested every three months and had their dosage adjusted until reaching the 40 ng/mL target. Afterward, their levels were monitored once a year.

Researchers tracked major cardiac events, including heart attacks, strokes, heart failure hospitalizations, and deaths. Out of 630 participants, 107 experienced such events. While there was no significant difference in the overall risk between the two groups, the chance of having a second heart attack was cut in half among those receiving targeted vitamin D₃ treatment.

“We’re excited with these results but know we have further work to do to validate these findings,” said Dr. May. Researchers plan to expand their work with a larger clinical trial to confirm and build upon these findings. “A larger study group will allow us to more fully evaluate whether targeted vitamin D management can reduce not only repeat heart attacks but also other forms of cardiovascular disease,” she said.

Knee arthritis? Try Aerobics!

A sweeping review of 217 studies representing 15,684 participants found that aerobic exercises like walking and cycling offer the best pain relief and mobility gains for knee osteoarthritis. Compared to other types of exercise, aerobic training showed the strongest evidence across short- and long-term outcomes. All forms of exercise were found to be safe, but experts recommend making aerobic activity the foundation of treatment as it’s the most effective for easing pain, improving movement, and enhancing overall quality of life.

Osteoarthritis develops when the cartilage cushioning the ends of bones wears down, leading to swelling, stiffness, and discomfort. It can affect any joint, but the knees are most commonly impacted. About 30% of adults over age 45 show signs of knee osteoarthritis on X-rays, and roughly half of them experience significant pain and mobility problems.

Exercise is a cornerstone of osteoarthritis care, yet many medical guidelines lack clear direction on which kinds are most beneficial for knee osteoarthritis specifically. To clarify this, researchers analyzed the effectiveness and safety of several exercise approaches.

The trials varied in quality, but the team assessed the strength of the evidence using the internationally recognized GRADE (Grading of Recommendations Assessment, Development and Evaluation) system. They examined several key outcomes: pain reduction, physical function, gait performance, and quality of life. Each was measured at short-term (4 weeks), mid-term (12 weeks), and long-term (24 weeks) follow-ups. Across these studies, aerobic exercise consistently ranked highest in improving outcomes among all exercise types tested.

Other exercise forms showed value too. Mind-body workouts likely provided a notable improvement in short-term function, neuromotor exercises likely boosted short-term gait performance, and strengthening or mixed routines improved function in the mid-term. Importantly, none of the exercise types resulted in more adverse effects than the control groups, indicating that these therapies are generally safe.

The authors did acknowledge some study limitations. Many results came from indirect comparisons, certain outcomes lacked long-term data, and smaller studies may have influenced some early findings. Despite these limitations, the researchers describe their work as one of the most complete and current evaluations of exercise for managing knee osteoarthritis. They believe the findings, which were published in The BMJ, will help doctors make more-targeted recommendations.

Based on the evidence, the team advises aerobic exercise “as a first-line intervention for knee osteoarthritis management, particularly when the aim is to improve functional capacity and reduce pain” and says if aerobic exercise is not possible owing to individual limitations, “alternative forms of structured physical activity may still be beneficial.”

Hydroxytyrosol from Olives Is a Neuroprotective Agent

Posted on January 4, 2026January 4, 2026 by The Olive Oil Hunter

One of the most powerful polyphenols in olive oil is hydroxytyrosol. Consuming hydroxytyrosol is linked to benefits in neurological, cardiovascular, and metabolic health, and the compound has demonstrated anti-inflammatory, anti-cancer, neuro-protective, and immuno-protective effects. A recently published scientific review in the journal Foods examines the growing body of evidence supporting the characterization of hydroxytyrosol as a “functional food,” with emphasis on its effects on neurological and cognitive processes.

What is it?

Hydroxytyrosol (hi-droxy-TY-roh-sol), abbreviated as HXT, is a phenol, a natural chemical that is both water-soluble and attracted to fats, which means that it can pass through cell membranes. Its chemical structure also explains its strong antioxidant and anti-inflammatory properties. HXT occurs mainly in olives—olive oil, fruit, leaves, and pulp—as well as in red and white wines.

What does HXT do in the brain?

HXT interacts with the brain and its vascular (blood vessel) system in 3 ways: 1) as an antioxidant and anti-inflammatory agent, HXT helps prevent damage to cerebral blood vessels and improves their function; 2) lab studies show that, by reducing oxidation and inflammation, HXT helps maintain the proper functioning of the blood-brain barrier (BBB), a crucial filter inside the brain’s blood vessels that controls what substances enter and exit the brain; 3) in studies in humans, consuming HXT in the form of high-phenolic EVOO resulted in less “leakage” across the BBB and, as reflected in participants’ performance on cognitive tests, improved connectivity between brain regions.

HXT and its metabolites (the components of a substance that are formed when metabolic processes, such as digestion, break it down) are able to cross the BBB to interact with specific brain processes, enhancing protective activity and dampening inflammatory activity that is linked to depression and cognitive decline.

How much HXT is needed to obtain its benefits?

In studies in humans, the above benefits were observed with an HXT intake ranging from 7 to 15 mg/day. In terms of EVOO, this translates to a daily consumption of about 25 to 50 ml of high-phenolic olive oil, or ~2 to 3 tablespoons. Table olives—regardless of their color or brining—also provide an excellent source of HXT.

What’s next for HXT?

This body of promising evidence has intensified interest in the development of HXT-enriched foods and other ways of delivering this health-promoting compound. HXT is highly bioavailable, which means that, after it is consumed and digested, it is readily absorbed and transported by the body. So, for now—perhaps for always—the most effective, efficient, and delicious way to obtain the neuroprotective benefits of HXT is “food-first,” via high-phenolic EVOO.

Fruit and Nut White Chocolate Truffles Recipe, Spotlight on Pistachios, The Scoop on Scoops, Coffee and A-Fib, Walk this Way to Cut Risks to Heart Health

Perfect for your New Year’s Eve celebration or to bring to a party, these luscious white chocolate truffles are a snap to make but look oh so elegant. As you set health goals for the coming year, simple lifestyle habits can have a big impact, especially on your heart. Read how coffee may stave off recurrent A-fib and how just 10 to 15 minutes of sustained walking can prevent many heart conditions.

Fruit and Nut White Chocolate Truffles

Fruit and Nut White Chocolate Truffles
Cranberries and pistachios pair so well in these creamy white chocolate truffles but have fun experimenting with your own combinations—the technique is exactly the same.
Ingredients
- 4 ounces dried cranberries
- 10 ounces shelled pistachios, divided use
- 1 pound white chocolate, preferably 35% cacao
- 1/2 cup heavy cream
- 2 tablespoons extra virgin olive oil
- 1 teaspoon vanilla extract
Directions

Step 1

Coarsely chop the cranberries and 4 ounces of the pistachios; set aside. Chop the rest of the pistachios more finely and transfer to a shallow bowl; set aside.

Step 2

Coarsely chop the chocolate; reserve 2 ounces and place the rest along with the heavy cream in a large microwave-safe glass bowl. Microwave at 30% power for 2 minutes, stir, and repeat until the chocolate is not quite fully melted. Out of the microwave, add the remaining chocolate to the bowl, let sit for 2 minutes, and then stir until smooth.

Step 3

Stir in the olive oil and vanilla, then fold in the coarsely chopped cranberries and pistachios. Turn the mixture onto a parchment paper–lined rimmed sheet pan or cookie sheet and gently flatten it with a spatula. Place in the fridge for 20 minutes to firm up for shaping.

Step 4

Once chilled, transfer the paper with the chocolate to your countertop and line the sheet pan with a clean piece of parchment. Using a 1-tablespoon scoop, make a truffle ball and drop it into the bowl of chopped pistachios. Roll it in the nuts, then place on the prepared sheet pan. Repeat with the rest of the chocolate.

Step 5

Place the pan in the fridge to firm up the truffles, about 20 minutes. If not serving right away, place them in a tin or covered dish and keep in the fridge. Refrigerated, the truffles will stay fresh for up to 2 weeks.
Yields about 4 dozen truffles

Healthy Ingredient Spotlight

Picking Pistachios

Shelled pistachios are the easiest for cooking as well as snacking, but keep in mind that they’re usually roasted and salted—not the best option for sweets. When using pistachios for baking, making truffles, or as a pretty garnish, for instance, look for shelled pistachios marked “raw.” These are in their natural state, unroasted and unsalted.

The Scoop on Scoops

Scoops with a spring-loaded handle are great for dishing out ice cream as well as for forming truffles, cookies, and even meatballs! You might already have one or more in your tool drawer. But if not or if you’re looking to expand the range of sizes you have, know that cookie scoops and ice cream scoops aren’t 100% interchangeable. Some cookie scoops are sturdier and might have sharper edges. I’ve always found that the spring-loaded handle is the most important feature because it allows you to release the food easily, preserving much of its rounded shape.

Scoops tend to come sized by the volume they hold, such as 1-, 2-, and 3-tablespoon (those measurements roughly correspond to 1.5, 1.75 and 2 inches in diameter), and you can find them all the way up to a 1/2 cup or more. Look for stainless steel and, if you use them often, an ergonomic design with a soft grip that’s easier on your hands.

Coffee and A-Fib

New research suggests that drinking coffee may help protect against atrial fibrillation, or A-fib, a common heart rhythm disorder that causes the heart to beat too quickly and irregularly, sometimes leading to stroke or heart failure.

For years, doctors have advised people with A-fib and other heart issues to stay away from caffeine, fearing it could worsen symptoms. But research done at the University of California San Francisco and the University of Adelaide in Australia found just the opposite.

“Coffee increases physical activity, which is known to reduce atrial fibrillation,” explained Gregory M. Marcus, MD, an electrophysiologist at UCSF Health and the senior author of the study, which was published in JAMA. Dr. Marcus added that “caffeine is also a diuretic, which could potentially reduce blood pressure and in turn lessen A-fib risk. Several other ingredients in coffee also have anti-inflammatory properties that could have positive effects.”

Rates of A-fib have been climbing in recent years, largely due to aging populations and increasing obesity. More than 10 million adults in the United States have been diagnosed, and experts estimate that as many as one in three people may experience the condition at some point in their lives.

To explore whether coffee helps or harms, the researchers designed the DECAF (Does Eliminating Coffee Avoid Fibrillation?) study, the first randomized clinical trial to test the relationship between caffeinated (despite the study’s acronym) coffee and A-fib.

The trial involved 200 patients who were regular coffee drinkers and had persistent A-fib or a related condition known as atrial flutter along with a history of A-fib. All underwent electrical cardioversion, a procedure that uses a controlled electrical shock to restore normal heart rhythm. Participants were randomly assigned to drink either at least one cup of caffeinated coffee or an espresso shot each day or completely avoid coffee and other caffeinated beverages for six months.

At the end of the study, the group that drank coffee experienced a 39% lower risk of recurring A-fib episodes. In addition to coffee’s potential anti-inflammatory effects, the researchers proposed that those who drank coffee may have naturally replaced less healthy drinks, such as sugary sodas, with coffee instead.

“The results were astounding,” said first author Christopher X. Wong, PhD, of UCSF, the University of Adelaide, and the Royal Adelaide Hospital. “Doctors have always recommended that patients with problematic A-fib minimize their coffee intake, but this trial suggests that coffee is not only safe but likely to be protective.”

Walk this Way to Cut Risks to Heart Health

New research revealed that walking in uninterrupted longer bouts of 10 to 15 minutes significantly lowers cardiovascular disease risk by up to two-thirds compared to shorter strolls of under 5 minutes.

An international team of researchers from the University of Sydney and Universidad Europea found that even people who walk fewer than 8,000 steps daily can see major heart health benefits simply by changing how they walk. Those who took their steps in one or two continuous sessions had lower rates of heart attacks, strokes, and death. Even when covering the same total number of steps, uninterrupted longer walks appear to provide greater benefits for the heart than do scattered short strolls throughout the day.

The work, which was published in the Annals of Internal Medicine, explored how walking patterns affect the health of people who are generally inactive. The study involved 33,560 adults between the ages of 40 and 79 who typically walked fewer than 8,000 steps a day and had no history of cardiovascular disease or cancer. Participants wore research-grade wristbands for one week to record both their step counts and how their steps were distributed throughout the day.

The researchers followed their health outcomes for about eight years and found striking differences in cardiovascular risk between those who walked in shorter versus longer bouts:

People who walked continuously for 10 to 15 minutes daily had only a 4% chance of experiencing a cardiovascular event such as a heart attack or stroke compared to a 13% risk among those who walked continuously for just 5 minutes a day.
The benefits were greatest for the least-active individuals, particularly those taking 5,000 or fewer steps. Within this group, the risk of developing cardiovascular disease fell from 15% among short walkers to 7% among those who walked up to 15 minutes at a time.
Among the most-sedentary participants (5,000 or fewer steps a day), the risk of death dropped from 5% for those walking in 5-minute bouts to under 1% for those taking longer walks.

Co-lead author Matthew Ahmadi, PhD, deputy director of the Mackenzie Wearables Research Hub and member of the Charles Perkins Centre at the University of Sydney, explained: “For the most inactive people, switching from brief walks here and there to longer continuous walks may come with some health benefits. There is a perception that health professionals have recommended walking 10,000 steps a day is the goal, but this isn’t necessary. Simply adding one or two longer walks per day, each lasting at least 10 to 15 minutes at a comfortable but steady pace, may have significant benefits, especially for people who don’t walk much.”

Senior author Professor Emmanuel Stamatakis, director of the Mackenzie Wearables Research Hub and physical activity theme leader at the Charles Perkins Centre, added: “We tend to place all the emphasis on the number of steps or the total amount of walking but neglect the crucial role of patterns—for example, how walking is done.”
