They train for years, work super-long hours and are required to make decisions that are literally life and death. So how do some of the world’s top cardiologists keep themselves nourished and hydrated while working in a field that can be physically and mentally punishing? Just in time for heart health month, we found the answers from these experts.

Private cardiologist, Hobart, Tasmania, Australia

First thing: Strong coffee, one shot caffeinated, one shot decaf (for “robust flavor without jitters from too much caffeine”), often with bit of butter blended in to make a “bulletproof” coffee

Midmorning: Another coffee, sometimes with a dash of cream

Lunch: A small snack, perhaps a piece of cheese

Dinner: Salad, often with plain yogurt, sometimes a few pickled vegetables and a protein (steak, chicken, pork or venison)

Evening: A glass of wine

Bishop, persuaded by recent research, has been following a pattern of eating during an eight-hour window and fasting for 16 hours. Still, he knows that may not work for everyone. “There isn’t a single, perfect diet for every person,” Bishop said. “It depends on each person’s dietary objectives.” He likens the way we eat to a bank account, where nutritious choices build up our balance so that we can “draw down” with an occasional indulgence from time to time.

“My recommendation is to follow the Mediterranean diet, which research shows to be very effective,” he said. “I tell my patients that you need to minimize eating food that has a bar code on it, and to avoid processed and sugar-dense foods as much as possible.”

Further, he pointed out that diet is only one pillar of good health. “For example, we often focus on diet and can neglect the importance of good sleep, regular exercise, reducing stress and periodic health checks and screenings.” 

Cleveland Clinic

First thing (around 5 a.m.): Two cups of coffee with sugar-free hazelnut coffee creamer and a teaspoon of sugar

Breakfast (8 a.m., at work): Fruit and veggie smoothie (low-carb and low-sugar) from plant-based delivery service. Favorite flavor: mint-basil

Lunch: One can of Diet Coke (her favorite indulgence) and a plant-based bowl from the same delivery service (usually a high-fiber choice with quinoa, beans and vegetables)

Afternoon snack: A salty treat like a handful of nuts or a small bag of baked chips

Dinner: Vegetable-based entrees, usually served with quinoa or pasta

Evening (10 p.m. to midnight): Two more cups of coffee as she catches up on work

“I try to keep my eating on a spectrum, and I try not to be too strict with myself,” Mattina said. “There might be times I have a deadline due, so I’m not cooking as much and eating out more, but then I get back on track the following week. I’d say about 80% of the time, I’m doing the right things.”

Mattina reported that her eating mostly follows the Mediterranean diet. “The only difference is that, as a pescatarian, I only eat fish, not any meat, since I’ve been a vegetarian since I was 16,” she said. “And I don’t drink alcohol, so there’s no wine at dinner for me.”

Surprised to see Diet Coke on the list?

Memorial Hermann Hospital, Houston

First thing: Large glass of water

Breakfast: Greek yogurt with fruit, perhaps nuts, or a boiled or scrambled egg or egg white with fruit and whole-wheat bread

Lunch: Chicken, fish or meat with vegetables, starch (ideally rice, which she loves) and possibly a salad, and water or iced tea

Snack (or quick lunch on busy days): Protein pack with meat, cheese and nuts, as low in sodium and saturated fat as possible, or low-fat cheese sticks or Greek yogurt with fruit

Dinner: Chicken or beef, either baked or grilled with veggies or a salad on the side with low-fat, low-sodium dressing. Weekly, a “free choice meal” at a favorite restaurant: usually steak with grilled shrimp, side Caesar salad, baked potato with chives and butter and dessert (ice cream, cake or flan)

“A firm ‘don’t’ for me is not to follow fad diets,” Landrau said. “I don’t like to classify certain food groups or nutrients as ‘bad,’ and I don’t totally avoid certain food groups. I never ask patients to deprive themselves of occasional treats if they can do it responsibly and with moderation. I tell them that the same way eating one salad won’t make them lose weight, one treat on a special occasion shouldn’t derail their efforts if they resume their healthy lifestyle after that.”

Cedars-Sinai Medical Center, Los Angeles

Breakfast: Yogurt with nuts, peanut butter on toast and a glass of milk, or leftovers from dinner

Lunch: Fruit and milk. Once or twice a month, lunch out with a colleague.

Dinner: Pasta with vegetarian topping, rice with vegetable and tofu topping, couscous or another whole grain with bean-based toppings. Fish about twice per week. Once or twice a month, dinner at a restaurant.

“I’m very comfortable eating good food,” Bairey Merz said. “I’m predominantly pescatarian, and I usually don’t eat dessert unless it’s very good chocolate.” She stresses that she refers to what she eats as “nutrition” instead of “diet.” “Diets are something for weight loss, but nutrition is the composition and amount of food you need to feel well.”

It's no surprise to see several mentions of the Mediterranean diet.

University of Michigan and the Ann Arbor VA Medical Center

Breakfast: A glass of water, one egg (fried or scrambled), a piece of fruit and a thermos of coffee with cream to take to work and sip throughout the day

Lunch: On clinical days he usually skips lunch, but might have a protein bar or piece of fruit. On research days, he’ll have a protein bar and plain yogurt.

Afternoon: A latte, if he’s feeling sluggish

Pre-dinner snack: Cheese and nuts (“and with a beer if I feel I’ve earned it”)

Dinner (8 p.m.): Three times weekly: Indian vegetarian food with rice, breads, vegetable and dal-based curries and yogurt. Other nights: Indian fusion with Mexican or Italian. Once a week: takeout.

Dessert: “I can go deep on cookies.”

“I aim to strive for balance in my eating, but I also believe life isn’t worth living without spicy food,” Nallamothu said. “I’m a big believer in Michael Pollan’s dictum: ‘Eat food. Not too much. Mostly plants.’ And I’ve been a vegetarian for about five years now. I started with one of my children who decided to become a vegetarian, and I’ve continued ever since.”

“The older I get, the more I realize how deeply personal food is for people. It is important for us to understand this diversity and be inclusive in how we think about diet and nutrition. Because of my involvement in the South Asian community in southeastern Michigan, I see a lot of patients who eat non-Western diets, including vegetarian ones. Providing dietary counseling for these patients has been a big gap until recently, but dietary counseling has evolved over the last few years in a very positive way.”

The Kitchen Tools That Help Chefs Stay Healthy
OXO Good Grips citrus squeezer(01 of07)

Sometimes it’s the little things that can make the biggest difference. A simple metal lemon squeezer is a go-to tool for cookbook author and content creator Robin Asbell.

“I like to add fresh lemon juice to vinaigrettes, pastas and dips, because it gives every dish a jolt of tartness and vitamin C,” she said. “Having vitamin C added to greens makes their iron content more absorbable, so it’s a win-win of taste and nutrition. In the past, I used two tools — a lemon reamer and a strainer — but I upgraded to a lemon squeezer, which gets the job done in one step. I put the juiced lemon halves in a glass, add cold water and sip on fancy spa water as I cook.”

A sturdy garlic press is also within easy reach in Asbell’s tool drawer. “It’s helpful for adding garlic to any dish without having to mince, and you don’t get that garlic stickiness or smell on your fingers,” she said. “Garlic is a healthy antioxidant and immune booster, so anything that makes it easier to add it to your cooking is great.” (credit:Amazon)
Le Creuset enameled cast iron signature round Dutch oven(03 of07)

“My Le Creuset Cast Iron Dutch Oven is a kitchen workhorse that helps keep me healthy,” said food designer Shelagh Mullen. “I’ve had it for 27 years, and cleanup is still a breeze. Plus, just lifting it is a workout."

“I’ve used it to make countless healthy soups and stews — and some decadent ones, too," she continued. "It creates the perfect simmer for an all-day chicken stock. These pots hold in the heat, and you can cook acidic foods, like fresh tomato sauce, without worrying about corrosion.”

The Dutch oven isn’t just for liquids, Mullen explained: “It’s also what I use to bake the most gorgeous gut-healthy, sourdough bread. I toss an ice cube into the screaming-hot pot, slide the dough in with a parchment sling and pop on the lid. Exactly 50 minutes later, I have a golden, crusty loaf of bread.”

Ninja BL455_30 Nutri Professional personal blender(04 of07)

A well-blended smoothie can be a good start to a healthy day, and our chefs have clear loyalties on the blenders they love best. “I’m obsessed with my Ninja BL455_30 Nutri Professional Personal Blender,” said Robin Selden, managing partner and executive chef of Marcia Selden Catering. “I begin my day with a protein smoothie, and this blender makes it so easy to do. I blend it in the 24-ounce cup, throw the pop-top on, and I’m on my way out the door.”

But while she praised its smoothie-making prowess, Selden said this blender does much more. “It’s awesome for blending soups, and I especially love it for gazpacho," she said. "I also use it for quick vinaigrettes and salad dressings. And, not going to lie, but there may have been some delicious skinny frozen margaritas I’ve made in my Ninja, too. The blades are so strong that they really crush through ice to make the best frozen cocktails ever.”

Vitamix Ascent Series smart blender(05 of07)

Other chefs praised the healthful options made possible with another blender brand: Vitamix. This brand is genius at making pureed veggie soups that help with eating more veggies, said Anna Klimmek, a chef, health coach and owner of Happy Food MN, a culinary wellness company. “Having those soups on hand helps curb cravings for savory comfort that I often get during cold winter evenings,” she said. “I also use it to make homemade nut milks and nondairy cheeses like cashew ricotta.”

But is a Vitamix worth the price? Chef Marshall O’Brien gives an unequivocal “yes.” “I tried other blenders, but I used them a lot, and they would always die out,” he said. “The Vitamix is very durable. I’ve had mine for more than 10 years and it’s still going strong.”

Dash deluxe electric air fryer(06 of07)

When you crave a comforting crunch without the grease, an air fryer can be a handy kitchen helper. Selden swears by her Dash Deluxe electric air fryer. “I get crispiness with little to no fat, and all in just a matter of minutes,” she said. “I can throw an entire head of cauliflower or broccoli, or a whole bag of mini sweet colorful peppers, in it for a few minutes, and everything emerges with a delicious texture.”

One of her favorite air fryer appetizers starts with a can of chickpeas. “You end up with these crunchy little protein-packed bites that you can season with specialty salts or Tajin seasoning,” she said. Her children especially love her air fryer Buffalo cauliflower. “I lightly spray florets with oil, and once they’re crispy and golden brown, I toss them with Frank’s Red Hot Sauce,” she said.

Cuisinart food processors (14 cup and 7 cup)(07 of07)

Speeding up prep time is a great incentive for cooking better at home. For Chef Rossi, owner and executive chef of New York caterer The Raging Skillet, a set of small and large Cuisinart food processors are the “secret ingredients” for many healthful meals. “In my early chef days, I remember killing myself chopping, smashing and mixing up the ingredients for a simple pesto,” she recalled. “A co-worker noticed and said, ‘Sweetheart, if you like suffering, there’s a lovely S&M bar down the street. If not, buy a food processor. Life is short.’"

“From the moment I brought my first Cuisinart to the kitchen, I was reborn, and there was no more mincing and moaning,” Rossi said. “I could make four quarts of pesto in less than 10 minutes. Hummus came together like magic. My vinaigrettes emulsified in seconds."

“Now, I can’t imagine my life as a caterer without my large Cuisinart, which I call my esposa, or wife, and my small one, nicknamed my esposo, or husband. Not only do they make my life easier, but I now find I can often actually leave work before sunset. Even in the middle of high wedding season, I can take a long walk by the river, breathe deeply and smell the flowers. Folks ask me what I do to stay trim and healthy. I tell them that my esposa does most of the work, so I have time to exercise and channel my inner child.”
