Saed News: Researchers analyzing nearly 30 years of data on American men and women found that healthy diets—whether low-fat or low-carbohydrate—can protect the heart only when they are based on high-quality, minimally processed foods.
According to SAEDNEWS, results from a large study involving nearly 200,000 people show that what matters more than reducing fat or carbohydrates is the quality of the food consumed.
The findings indicate that diets rich in vegetables, fruits, whole grains, healthy fats, and quality protein sources are associated with better cardiovascular health. In contrast, diets dominated by processed foods, unhealthy fats, and certain animal proteins—even if classified as low-fat or low-carb—are not necessarily beneficial for the heart.
Researchers observed that individuals who followed high-quality diets:
Had higher levels of good cholesterol (HDL)
Had lower blood fat levels
Showed lower inflammatory markers
Were less likely to develop coronary heart disease
Coronary heart disease is one of the leading causes of heart attacks.
For years, supporters of low-carb and low-fat diets have debated which is better. However, this study suggests that focusing only on cutting fat or carbohydrates does not guarantee better heart health.
Researchers emphasize that individuals can choose different dietary patterns based on preference and lifestyle, as long as food quality is prioritized.
Experts recommend increasing intake of:
Fresh vegetables and fruits
Whole grains
Legumes
Nuts and seeds
Olive oil and other healthy fats
Fish and lean protein sources
They also recommend limiting ultra-processed foods, sugary drinks, fast food, and unhealthy fats.
The study suggests that heart health is not about strictly counting calories, fat, or carbohydrates. Instead, choosing high-quality, minimally processed foods is more important. A diet rich in natural foods, whole grains, vegetables, and healthy fats may have a greater impact on heart health than restrictive low-fat or low-carb diets.
