Why nature-based medicine is the future of health care

Education

April 29, 2026

This month, 53 medical schools committed to requiring 40 hours of nutrition education. As the physician who co-taught the first U.S. medical school class in culinary medicine, with Mike Roizen, MD, founding director of the Cleveland Clinic Wellness Institute, I am proud that culinary medicine is now taught in roughly 80 percent of U.S. medical schools. I recognize this as a genuine win. But I have watched this story before, …

Why cooking for better health makes dietary changes easier

Oliver Power

Conditions

April 26, 2026

Recently, my mother was told by her doctors that her high blood pressure was a concern and that she needed to make dietary changes and eat foods lower in sodium. Seemed simple. To my mother, what was clear was the need for significant dietary change to stay below 2,300 mg of sodium, the recommended limit by the American Heart Association. Sure, she would make sure to not eat food overpowered …

Rethinking nutrition policy on ultra-processed food

Hana Kahleova, MD, PhD

Conditions

April 24, 2026

For more than a decade, the phrase “ultra-processed food” has functioned as nutritional shorthand for danger, a dietary villain blamed for rising rates of obesity, diabetes, and heart disease. The public message has been simple: If it is ultra-processed, avoid it. But science is rarely that simple.

My colleagues and I recently reviewed the growing body of research examining ultra-processed foods, not as a single monolithic category, but as distinct …

Why clinician education must prioritize nutrition training

Beata Pasek, EdD

Conditions

March 19, 2026

When I began coordinating GI research in inflammatory bowel disease (IBD), I noticed something unexpected: Second- and third-year GI fellows, bright, motivated, steeped in medical science, had received little to no formal training on diet’s role in disease. For many, nutrition was treated as peripheral, “something dietitians handle,” rather than core physician knowledge.

This is not a reflection on their ability or commitment. It reflects how medical education is structured. U.S. …

The physiology of heartbreak: hormones, ischemia, and healing

Sara Police, PhD

Conditions

March 16, 2026

As a nutritional scientist and educator, I spend a lot of time thinking about the heart through a lens of physiology, metabolism, and medicine. I aim to reduce risk for cardiovascular disease by sharing evidence-based nutritional strategies. As a human, I realize an equally dangerous health risk can begin in one’s emotional heart. We are hardwired for connection. In this regard, the heart seems simultaneously the strongest and most fragile …

The evolutionary intelligence of human milk: HMOs and lactose

Rao M. Uppu, PhD

Conditions

March 12, 2026

Human milk contains more than nutrients; it carries a quiet, evolutionary intelligence expressed through chemistry. It is not conscious thought, but the slow wisdom of evolution written into molecules that nourish, protect, and guide.

Among its most remarkable ingredients are the human milk oligosaccharides (HMOs). These complex sugars, present at around 0.5 to 1.5 g/dL, are not there to feed the infant directly.

They move through the stomach and small intestine largely …

High-protein diet risks: Why more isn’t always better

Farid Sabet-Sharghi, MD

Conditions

February 4, 2026

Over the past decade, nutrition culture has increasingly revolved around a single macronutrient: protein. Popular media, fitness culture, and everyday health conversations often frame higher protein intake as a universal good, synonymous with strength, longevity, and metabolic health. In the process, many foods that once formed the foundation of balanced eating (whole grains, legumes, vegetables, and healthy fats) are quietly sidelined or dismissed.

Protein is essential. That point is not in …

Alcohol, dairy, and breast cancer risk

Delta Airlines has been raising money for the Breast Cancer Research Foundation by selling cocktails and rosé on board flights for 20 years. This month, it’s Une Femme Sparkling Rosé. Delta also serves gouda and cheddar slices, along with chicken salad sandwiches topped with queso. Have a drink or two, snack on cheese, and feel good about sending money for research, a party for a cause.

Yet, studies have shown that …

Why a 500-calorie meal isn’t always fit

Larry Kaskel, MD

Conditions

October 8, 2025

I was watching Michigan take on Nebraska the other Saturday when a popular sandwich chain dropped its latest ad: “Our new 500-calorie Fit Sandwich!” Catchy. Marketable. But let’s be honest, it’s mostly bread, a little processed meat, and not much else. Yes, it comes in under 500 calories, but so does half a sleeve of Oreos. Does that make Oreos “fit”? This is the oldest trick in nutrition marketing. We …

Psychiatrist tests ketogenic diet for mental health benefits

Zane Kaleem, MD

Conditions

September 17, 2025

When I was in my studies as a psychiatry resident, I learned about an interesting field called metabolic psychiatry, which focuses specifically on ketogenic therapies to treat psychiatric conditions. This is a nascent field at this time, with no extensive clinical trials like we have for medications, though some small trials exist. I even have some patients who have been on ketogenic diets (not prescribed by me) …

The hidden battle of weight loss: Why dieting alone isn’t enough

Richard A. Lawhern, PhD

Conditions

July 31, 2025

Among Americans and Europeans, overweight and obesity are endemic. Excess weight is also a primary or contributing cause and a significant risk factor for many chronic diseases, including diabetes, heart disease, stroke, several cancers, liver and kidney diseases, respiratory and musculoskeletal disorders, and mental health problems.

That being said, one can read any amount of advice we can make time for, concerning dieting or exercise. But a harsh reality persists: Fat …

Integrating vitamin education in mental health care

Scarlett Saitta

Conditions

July 27, 2025

For a long time, I was close-minded to the idea of vitamin supplementation as a meaningful part of mental health treatment. Like many in medicine, I saw it as misguided at best and more a part of wellness culture than real science. However, over time, I realized how often we mistake “That makes sense to me” for “That’s objectively true,” as we are prone to fall prey to our mental …

Why patients need a registered dietitian on their health care team

How’s your cholesterol? Are you getting enough protein? Do you even know? Whether you’re a doctor, a patient, or both, you may be missing out on the powerful benefits of a registered dietitian.

Recently, I received lab results that were concerning, and my doctor suggested adding another medication. I’m focused on reducing medications, so I wanted to explore all possible ways to improve my numbers safely without adding to my pill …

As both a physician and a certified culinary medicine specialist, I know firsthand how a nutritious diet can prevent and treat diet-related diseases. Diabetes, hypertension, cardiovascular disease, and other conditions are becoming increasingly more common. Over and over, the science tells us that a low-fat vegan diet, rich in fruits and vegetables, can help patients suffering from these conditions. Physicians can do our part to help patients use …

The power of personal and cultural connections in dietary advice

Sometimes the most honest conversations about health don’t take place in a doctor’s office, but in the waiting room of a Jiffy Lube instead. While trying to pass time as I waited for my oil change, I eavesdropped on a conversation between two strangers. What started as lighthearted banter quickly turned into a candid discussion about their struggles with blood pressure and cholesterol. One man admitted he never takes his …

From Super Bowl to supermarket: How candy ads shape kids’ diets

A gummy candy shimmies on stage, dancing to Flashdance. The music swells; it pulls a chain and is showered in multi-colored candies. The ad, for Nerds Gummy Clusters, was one of dozens of food ads that 123 million people saw during the 2024 Super Bowl. While the nostalgic soundtrack entertained adults, the cartoon candies were engineered to appeal to a different audience: children.

As the world emerges from COVID-19, we must remember there is a silent yet devastating health crisis: our diets. In this era, convenience reigns supreme, with ultra-processed foods infiltrating everyone’s lives, leading to surges in preventable diseases and deaths. This crisis is more than individual food choices; it is a systemic issue affecting millions, especially in low-income communities.

One of the biggest drivers of the crisis is the ubiquity of …
