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.

The latest study results echo the conclusions of similar past studies. Macro profiles alone can't shield your heart health. If you fill a low-fat diet with sugary snacks, your glycemic load and insulin spikes will drive endothelial dysfunction. If you fill a low-carb diet with processed meats and butter, your lipid profile may drastically change. Either one of those drive gut microbiome changes.

Several of the most reliable studies for long-term cardiovascular health now show that food quality is what ultimately matters most. A balanced diet of minimally processed foods keeps our body working to break down complex foods into critical nutrients. The more processed the food becomes, the more inflammation and oxidation is triggered throughout your body.

Either macro split achieves better heart health when paired with high-quality, minimally processed foods. Preferably whole grains and legumes for carbs, along with healthy fats from olive oil, nuts, fatty fish and avocado.

Alex Cornici · Answer

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!

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.

In my practice at OptumMD, I've seen how processed foods with added sugars and refined carbs can spike inflammation markers, even in patients following strict low-carb diets. I recommend focusing on whole foods like leafy greens, lean proteins, and healthy fats - just last month, my patient Jim reversed his pre-diabetes by switching from processed low-fat snacks to nutrient-dense meals with quinoa, wild salmon, and avocados.

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.
