In young to middle-aged Indian men living in cities who have high triglycerides and low good cholesterol, eating more fiber, protein, and vitamin C while eating less fat and sugar is linked to a higher score on a special diet quiz—meaning the quiz might be good at spotting healthy eating habits that help heart health.

In Indian men living in cities who have high cholesterol, those who eat healthier according to a special diet score tend to have less body fat, lower weight, and less body inflammation — and those with the worst scores have the highest levels of these risk factors, suggesting the diet score might help spot heart disease risks.

Among middle-aged American Indians, people who ate more fat — especially saturated fat — were more likely to die from heart disease than those who ate less, even when other health factors were taken into account.

In men in Indian cities who have high cholesterol, eating a healthier diet for 12 weeks might help lower a marker of body inflammation, but we can’t be sure yet because the results weren’t strong enough to count as proof.
