Cardiologists, nutritionists, and dietitians: A new study that followed almost 200,000 people for several decades has found that when it comes to heart health, the quality of food consumed matters as much as following a low-carbohydrate or low-fat diet. Seeking commentary, including: (1) Why does food quality matter just as much as following a low-carb or low-fat diet? (2) How can people follow a heart-healthy diet that contains good quality food and is low-carb or low-fat?

The overall balance of diet is more important than just sticking to one principle or one mantra. Also, our body's nutritional requirements change over time and so a 'one size fits all' paradigm may not work. Some things like trans and saturated fats should be avoided at all stages of life. Why food quality matters as much as following a low-carb or low-fat diet: 1. Nutrient Power: High-quality foods provide essential vitamins, minerals, and antioxidants that reduce inflammation and protect the heart, which merely cutting carbs or fats without considering quality doesn't guarantee. 2. Better Bodily Processes: Quality foods positively influence inflammation and gut health, both crucial for heart health, whereas processed options can harm these regardless of carb or fat levels. How to follow a heart-healthy diet that contains good quality food and is low-carb or low-fat: 1. Focus on Wholesome Foods: Whether low-carb or low-fat, prioritize whole, unprocessed foods like vegetables, lean proteins, and healthy fats (for low-carb) or fruits, whole grains, and lean proteins (for low-fat). 2. Choose Smart Fats and Carbs: In low-carb diets, select unsaturated fats (avocados, nuts) over excessive saturated fats. In low-fat diets, opt for complex, high-fiber carbs (whole grains, legumes) over refined ones.

1. Why food quality matters just as much as low-carb or low-fat for heart health—especially in recovery: For individuals in recovery from substance use disorders, cardiovascular health is a long-term priority that begins with lifestyle repair. Many people enter sobriety with years of poor dietary habits, inflammation, and metabolic disruption—especially if substances like alcohol, stimulants, or opioids were involved. The recent study highlights what we emphasize in treatment every day: it's not just about cutting carbs or fat—it's about feeding the body well. Diets high in processed foods, sugars, and low-quality fats increase systemic inflammation, which worsens mental health and raises cardiovascular risk—a common concern in addiction recovery. Nutrient-dense, high-quality food helps stabilize mood, reduce cravings, and support physical healing. 2. How people in sobriety can follow a heart-healthy diet that emphasizes food quality—whether low-carb or low-fat: At Legacy Healing Center, we work with individuals to rebuild their relationship with food—not through restriction, but through education and intentionality. A low-carb plan in recovery might center on lean proteins, non-starchy vegetables, nuts, seeds, and healthy fats like olive oil or avocado—foods that regulate blood sugar and reduce inflammation. A low-fat approach might emphasize fiber-rich legumes, fruits, vegetables, and whole grains, paired with lean proteins and omega-3s to support heart and brain health. Regardless of the approach, the key is to avoid ultra-processed, sugary, or fried foods that mimic the dopamine-driven cycles common in substance use. Nutrition is a form of relapse prevention—it fuels the brain, repairs the body, and builds a foundation for long-term wellness. Recovery isn't just about quitting substances; it's about learning to live—and eat—with purpose.

From all I've seen and learned, eating good quality food is as important as managing your carb or fat intake, mainly because quality food usually packs more nutrients and fewer harmful additives. When you eat highly processed foods—even if they're low-carb or low-fat—they often contain hidden sugars, unhealthy fats, and excessive sodium, all of which can negatively impact heart health. Plus, quality foods like fresh vegetables, lean proteins, and whole grains tend to be more filling and provide essential nutrients that help keep your heart working properly. To stick to a heart-healthy diet that’s rich in quality foods while still being mindful of carbs and fats, start by focusing on whole, unprocessed foods. Cooking at home more can make a big difference since you control what goes into your meals. Try to incorporate a variety of fruits and veggies, choose whole grains over refined ones, and opt for lean protein sources like fish, poultry, or legumes. If you need to watch your fats, focus on the healthy kinds found in nuts, avocados, and olive oil. Remember, balancing your diet doesn't have to be a chore or about denial—just a few smart choices can set you right up for a healthier heart!

Food quality matters as much as the macronutrient ratio because not all carbs or fats are created equal. In my experience working with patients, whole, minimally processed foods provide essential nutrients and fiber that support heart health, while processed options—even if low in carbs or fat—often contain additives and unhealthy fats that can increase cardiovascular risk. To follow a heart-healthy diet that's low-carb or low-fat without sacrificing quality, I advise focusing on nutrient-dense foods like leafy greens, nuts, fatty fish, and whole grains. For a low-carb approach, prioritize vegetables and healthy fats from sources like olive oil and avocados. If opting for low-fat, emphasize lean proteins and fiber-rich foods while avoiding refined carbs and sugars. Balancing food quality with macronutrient goals helps ensure the diet supports overall cardiovascular health sustainably.

Good Day, Low-carb-low-fat diets alone do not guarantee good health. Products with trans fats and added sugars still wreak havoc on health, spiking inflammation and risks for heart disease. Eating whole foods rich in nutrients improves blood sugar, cholesterol, and metabolic health. Lessening the risk factors for chronic ailments through healthy lifestyle choices such as eating a nutritious diet and exercising consistently is important. Top your plate with more veggie greens, lean protein, and healthy fat meals. Less processed foods, trans fats, and refined carbs, choose foods that support heart health and overall well-being.

At Mission Prep Healthcare, I've observed that our adolescent patients show better treatment outcomes when we serve nutrient-rich meals instead of just counting calories or carbs. Last semester, we revamped our meal program to include more colorful vegetables, lean proteins, and healthy fats, which not only improved our patients' physical health markers but also their mood stability and energy levels.

In my restaurants, I've noticed that guests who order dishes made with fresh, high-quality ingredients consistently report feeling better and more satisfied than those choosing heavily processed options, regardless of the macronutrient content. I always recommend starting with fresh, whole ingredients and cooking methods that preserve nutrients - like grilling fish with herbs or roasting vegetables with a touch of olive oil - rather than focusing solely on counting carbs or fats.

Understanding food quality is vital for heart health. High-quality, nutrient-dense foods like whole grains, fruits, vegetables, lean proteins, and healthy fats support overall well-being, reduce inflammation, and help maintain a healthy weight. In contrast, low-quality processed foods high in sugars and unhealthy fats can negatively impact heart health. Thus, focusing on quality in dietary choices is essential for both cardiologists and nutrition professionals.
