Eating These Fruits as Good for Heart as 4,000 Steps, Study Reveals

VIVA – A study reveals that eating just a few pieces of fruit and vegetables each day is the equivalent of taking 4,000 thousand steps for your physical fitness, and heart. Over two thousand participants had to run on a treadmill while their oxygen levels were measured by Harvard researchers. 

People who stuck closely to a Mediterranean-style diet, comprising lots of fruits, vegetables, and whole grains, had the same fitness level as people who took around 4,000 steps per day in the researchers' previous studies.

Fruit and vegetables are high in fiber, which works as a natural fat burner that can help boost your metabolism. They are also high in antioxidants which stave off inflammation and other health problems.

"This study provides some of the strongest and most rigorous data thus far to support the connection that better diets may lead to higher fitness. The improvement in fitness we observed in participants with better diets was similar to the effect of taking 4,000 steps more steps each day," Lead author of the study Dr Michael Mi, of Harvard's Beth Israel Deaconess Medical Centre stated.

Healthy diets are known to reduce the risk of heart disease and cancer, two of America's biggest killers. 

Among people who do the same amount of physical activity, there are differences in fitness - suggesting additional factors are involved. The study of 2,380 middle-aged American men and women identified nutrition as a key factor. 

Participants completed a food frequency questionnaire to assess the consumption of 126 items during the last year, ranging from never or less than once per month to six or more servings per day.

The information was used to rate diet quality using the Alternative Healthy Eating Index (AHEI; 0 to 110) and Mediterranean-style Diet Score (MDS; 0 to 25), which are both associated with heart health.

Higher scores indicated a better quality diet emphasizing vegetables, fruits, whole grains, nuts, legumes, fish, and healthy fats and limiting red meat and alcohol.

"In middle-aged adults, healthy dietary patterns were strongly and favorably associated with fitness even after taking habitual activity levels into account. The relationship was similar in women and men, and more pronounced in those under 54 years of age compared to older adults," Dr Mi explained.
