During a global pandemic, everyone is stressed. Work is different, families are separated, friends are distant and everyday routines seem to be forever changed.
A recent poll reports that 45% of Americans feel that their mental health has been negatively impacted due to worry and stress over the novel coronavirus.
Increased stress can weaken immune functions. Ongoing stress triggers high levels of cortisol, a steroid hormone. Not only does excess cortisol diminish immune functions, it has been shown to increase disease risk while shortening lifespans.
Over the last 15 years, studies have revealed that long-term overexposure to excess cortisol disrupts almost all body processes, increasing risk for health problems that include:
- Chronic complications: Including high blood pressure, type 2 diabetes and osteoporosis.
- Weight gain: Cortisol increases appetite and signals the body to shift metabolism to store fat.
- Tiredness: It interferes with daily cycles of other hormones, disrupting sleep patterns and causing fatigue.
- Impaired brain function: Cortisol interferes with memory, contributing to mental cloudiness or “brain fog”.
- Neurodegeneration, including Alzheimer’s disease
- Anxiety, depression, and insomnia
- Infections: It hampers the immune system, making you more prone to infections.
In rare cases, very high cortisol levels can lead to Cushing’s syndrome, a rare but serious disease.
Cortisol is one of the body’s main stress hormones. During stressful times, the adrenal glands release it as part of the “fight-or-flight” response. This flood of cortisol is necessary for life-or-death situations, directing a complex series of hormonal and physiological changes that support either fleeing to safety or fighting off the threat.
Cortisol boosts muscle tension, blood sugar, heartbeat, tissue-repair substances, and mental focus. At the same time, cortisol turns down non-urgent processes such as immune functions, along with the digestive and reproductive systems. When the stressful threat has passed, cortisol is supposed to return to normal “balanced” levels.
The body relies on effective communication between the following three parts of the body to release the correct amount of cortisol:
- the adrenal gland
- the pituitary gland
- the hypothalamus, which is part of the brain
Between them, they stimulate the production of cortisol when the body needs it and block it when the levels need to drop back down.
When stressors are almost always present, as they have been since the coronavirus outbreak and the social unrest after the killing of George Floyd, for many cortisol remains “turned on.” Its continuing high presence in the blood adversely affects critical functions of the body and brain.
Stress results in a decrease in levels of lymphocytes. These immune cells are used to kill viruses and other invaders. Lymphocyte counts are often reduced when one is fighting a viral infection.
Even if it’s just for a few days, social isolation and loneliness, both common during the current pandemic, can also weaken immunity.
Most worrisome, chronically elevated cortisol is linked to increased mortality risk. A large study of people over age 65 found that men with high cortisol levels were 63% more likely to die than those with lower levels. Women with elevated cortisol were 82% more likely to die than those with low levels. And those with high urinary cortisol had a five-fold increased risk of death from cardiovascular disease.
Higher cortisol is also associated with shortening of telomeres, the stretches of DNA that cap the ends of chromosomes. As telomeres shorten, the cells that bear them get closer to the ends of their lives, aging tissues and organs.
Of course, nutrition can influence cortisol!
Sugar intake is a trigger for cortisol release. Regular, high sugar intakes may keep your levels elevated. Interestingly, sugar can also reduce the amount of cortisol released in response to specific stressful events. This explains why sweet desserts are good comfort foods, but frequent or excessive sugar increases cortisol over time.
Additionally, a few specific foods can benefit cortisol levels:
- Dark chocolate: Two studies of 95 adults showed that consuming dark chocolate reduced their cortisol response to a stress challenge. My current favorite organic, dairy-free chocolate is from Hu Kitchen. Always buy chocolate with at least 70% cacao.
- Many fruits: A study of 20 cycling athletes showed eating bananas or pears during a 75-km ride reduced levels compared to drinking only water.
- Black and green tea: A study of 75 men found 6 weeks of drinking black tea decreased cortisol in response to a stressful task, compared to a different caffeinated drink.
- Probiotics and prebiotics: Probiotics are friendly, symbiotic bacteria in foods such as dairy-free yogurt, sauerkraut and kimchi. Prebiotics, such as soluble fiber, provide food for these bacteria. Both probiotics and prebiotics help reduce cortisol.
- Water: Dehydration increases cortisol. A study in nine male runners showed that maintaining hydration during athletic training reduced cortisol levels.
Lifestyle
Keep a consistent sleep schedule, avoid caffeine in the evening, avoid sleep interruptions and get seven to eight hours of sleep daily to keep cortisol in a normal rhythm.
Exercise during the day decreases cortisol at night. Intense exercise increases cortisol in the short term due to stress on the body.
“Stress mindfulness” emphasizes self-awareness of stressful thoughts and signs of body tension. Becoming more aware of stress and its triggers is the first step to successfully coping with stress.
Many relaxation techniques are proven to lower cortisol. Examples include deep breathing, yoga and tai chi, music and massage.
Tending to your own happiness will help keep cortisol down. Taking up a hobby, spending time outdoors and laughing can all help.
Relationships with friends and family can lead to happiness but also to stress. Spend time with those you love and learn to forgive and manage conflict for better emotional and physical health.
Several studies show that interacting with an animal companion reduces stress and lowers cortisol levels. Pets also benefit from positive relationships with their humans.
Resolving guilt improves life satisfaction and cortisol levels. This may involve changing habits, forgiving others or learning to forgive yourself.
For those with spiritual inclinations, developing faith and participating in prayer can help control cortisol. Whether you’re spiritual or not, performing acts of kindness can also improve your cortisol levels.
Dill
Dill is native to southern Russia, western Africa and the Mediterranean region. The seeds are stronger and more flavorful than the leaves and are most commonly associated with the cuisines of Scandinavia and Germany.
Also called dill weed, the plant has slender stems with alternating soft leaves and brown, flat, oval seeds. Dill leaves have a sweet, grassy flavor and dill seeds are more aromatic, with a slight citrus flavor that’s similar to caraway seeds.
In addition to culinary uses, dill is rich in several nutrients and has traditionally been used to treat various ailments, including digestive issues, colic in infants, and bad breath.
One cup of fresh dill sprigs provides approximately:
- Calories: 4
- Vitamin C: 8% of the Daily Value (DV)
- Manganese: 5% of the DV
- Vitamin A: 4% of the DV
- Folate: 3% of the DV
- Iron: 3% of the DV
Fresh dill is very low in calories and it is a good source of several essential vitamins and minerals, including vitamin C, manganese, and vitamin A.
Dill seeds have many similar nutritional benefits. One tablespoon of seeds provides 8% of the DV for calcium, 6% of the DV for iron, and 1–5% of the DV for magnesium, manganese, phosphorus, and potassium.
“Dill” is derived from the Old Norse word “dilla,” which means to soothe, dill has been used since ancient times to treat colic in infants and digestive diseases, as well as to help with breastfeeding.
Both the seeds and leaves of the dill plant have been found to be rich in several plant compounds with antioxidant properties, including:
- Flavonoids. These plant compounds have been associated with a reduced risk of heart disease, stroke, and some forms of cancer. They may also play an important role in brain health.
- Terpenoids. These compounds are found in essential oils and may protect against liver, heart, kidney, and brain diseases. Monoterpenes are a class of terpenes, which are naturally occurring plant compounds that are linked to anticancer, antiviral, antifungal, and anti-inflammatory properties. They are commonly found in essential oils of plants like dill and have been associated with anticancer properties. Dill is high in monoterpenes, particularly d-limonene, which may have anticancer properties and help prevent and treat lung, breast, and colon cancer.
- Tannins. Responsible for bitterness in many plant foods, tannins have been shown to have potent antioxidant properties, as well as antimicrobial effects.
- The activity of dill’s volatile oils qualify it as a “chemoprotective” food ( like parsley) that can help neutralize particular types of carcinogens, such as the benzopyrenes that are part of cigarette smoke, charcoal grill smoke, and the smoke produced by trash incinerators.
- The total volatile oil portion of dill has also been studied for its ability to prevent bacterial overgrowth. In this respect, dill shares the stage with garlic, which has also been shown to have “bacteriostatic” or bacteria-regulating effects.
Flavonoids, like those found in dill, have been shown to protect heart health due to their potent antioxidant and anti-inflammatory properties.
One study in 91 people with high total cholesterol and triglyceride levels found that taking 6 dill extract tablets daily for 2 months significantly improved total cholesterol and triglyceride levels but did not change HDL (good) cholesterol levels.
Dill has been suggested to have blood-sugar-lowering effects. In fact, several studies in animals with diabetes have shown a significant improvement in fasting blood sugar levels with daily doses of dill extract.
Dill also has:
- Antibacterial properties. Essential oils in dill have antibacterial effects which fight potentially harmful bacteria, such as Klebsiella pneumoniae and Staphylococcus aureus.
- Bone health. Dill contains calcium, magnesium, and phosphorus all of which are important for bone health.
- Menstrual cramps. Essential oils in dill may help relieve pain from cramps during your period. However, research is currently limited and mixed.
Dill is generally safe for consumption. However, in rare cases it has been shown to cause allergic reactions, vomiting, diarrhea, an itchy mouth, swollen red bumps on the tongue, and throat swelling. People who are allergic to carrots may experience an allergic reaction to dill.
Additionally, it’s recommended to avoid dill pills or extracts during pregnancy and breastfeeding as there’s limited research of their safety. People with diabetes, who are taking lithium, and those undergoing surgery within two weeks should talk to their healthcare provider before using dill as a medicine.

How to Buy
Whenever possible, choose fresh dill over the dried form of the herb. The leaves of fresh dill should look feathery and green in color. Dill leaves that are a little wilted are still acceptable since they usually droop very quickly after being picked.
Even though dried herbs and spices are widely available in supermarkets, check local spice and ethnic stores in your area. Oftentimes, these stores have a better selection of dried herbs and spices that are of superior quality and freshness compared to those offered in regular markets. Just like with other dried herbs, select organically grown dill seeds since this will give you more assurance that the spice has not been irradiated.
How to Store
To store fresh dill, rinse the leaves with fresh water, wrap the sprigs loosely in a paper towel and then place the dill in a cloth bag. I use Ambrosia Storage Bags.
Store the dill in the vegetable drawer of your fridge for up to 1 week. For longer storage, you can also freeze fresh dill by rinsing and then placing the sprigs in a single layer on a cookie sheet in the freezer.
Once frozen, transfer the sprigs to a reusable silicone bag, like Stashers, and return to the freezer for up to 6 months for best flavor.
Frozen dill can be used in cooking without thawing first. Dried dill and dill seeds should be stored in an airtight container in a cool, dark place for 6 months to 1 year.
How to Cook
Here are some ways to add fresh dill to your meals:
- Use it as a garnish for soups or roasted vegetables.
- Sprinkle it on top of cold cucumber salads.
- Use it in potato salads or on baked or roasted potatoes.
- Stir it into yogurt-based dips like tzatziki.
- Chop and add it to salads.
- Add it to baked breads.
- Incorporate it into sauces, marinades, or salad dressings.
Dried dill can also be used to add flavor to dips, marinades, and potato salads.
As for the seeds, dill seeds can be used whole or crushed and added to bread, soups, or vegetable dishes. They can also be used to make dill pickles.
Vegan Turkish Kebabs with Sumac Onions and Garlic Dill Mayonnaise J. Kenji López-Alt/ Photo: Kate Mathis for The New York Times. Food Stylist: Eugene Jho
4 Servings
4 Servings

Ingredients
FOR THE SUMAC ONIONS:
- 1 medium red onion, halved lengthwise, then thinly sliced
- 1 cup loosely packed fresh parsley leaves
- 1 tablespoon ground sumac
FOR THE GARLIC-DILL MAYONNAISE:
- 20 garlic cloves, peeled and ends trimmed
- 1 cup vegan mayonnaise
- 1 tablespoon fresh lemon juice
- 3 tablespoons extra-virgin olive oil
- Large handful of minced fresh dill leaves
- Kosher salt and freshly ground black pepper
FOR THE KEBABS:
- 1 pound vegan ground meat, such as Impossible or Beyond
- 1 tablespoon minced fresh oregano leaves
- 3 medium garlic cloves, minced
- 1 ½ teaspoons Urfa pepper, or 1 teaspoon ground ancho chile
- 1 ½ teaspoons ground sumac
- 1 teaspoon kosher salt
- 1 teaspoon ground cumin
- ½ teaspoon ground coriander
- ½ teaspoon freshly ground black pepper
FOR SERVING:
- 1 teaspoon neutral oil, such as grapeseed or canola
- 1 cup cherry tomatoes, halved
- 1 cup arugula
- Hot sauce, to taste
- Vegan Turkish bread or pita
Instructions
- Make the sumac onions: Combine all ingredients and toss until the onion pieces are separated and well coated. (You should have about 1 1/2 cups. Sumac onions should be used the day they are made.)
- Make the garlic-dill mayonnaise: Put 18 garlic cloves in a medium pot, and cover with a couple inches of water. Bring to a boil over high heat. Continue cooking for 30 seconds. Drain garlic and allow to cool to room temperature.
- Meanwhile, mince the remaining 2 garlic cloves. In a food processor, combine blanched and raw garlic, mayonnaise and lemon juice; process until completely smooth. With the machine running, slowly drizzle in the olive oil. Transfer mixture to a bowl, stir in minced dill, and season to taste with salt and pepper. (You should have about 1 1/2 cups.)
- Make the kebabs: Combine all ingredients in a large bowl, and fold with very clean hands until fully incorporated. Divide mixture in half, then divide each half into 6 equal balls. Working on a clean cutting board, roll them into cylinders about 3/4 inch in diameter. Cut each cylinder in half to form 24 small logs.
- Cook and serve: In a large skillet over medium-high, heat oil until shimmering. Add the logs, working in batches if necessary to prevent crowding. Cook on one side until well browned, about 2 minutes. Flip and cook on second side until well browned and cooked through, another 1 1/2 minutes. (Alternatively, cook on a hot grill until lightly charred and cooked through.) Transfer to a serving plate.
- Serve with sumac onions, garlic-dill mayonnaise, cherry tomatoes, arugula, hot sauce and Turkish bread or pita.
