Eating a Mediterranean-Style Diet May Equal Taking 4,000 More Steps

Eating a Mediterranean-Style Diet May Equal Taking 4,000 More Steps

A healthy diet provides the body with fluid, micronutrients (vitamins and minerals) and food energy. Choose mostly low-fat foods and cut back on processed foods. Eat dark green vegetables and fruit (2 or more servings a day). Choose whole grain breads and cereals, brown rice, quinoa, barley, amaranth or oats which are high in fibre. Drink fat-free milk, lower fat yoghurts and reduced fat cheese.

  • New research is suggesting that what we eat can also help contribute to our daily step goals by as much as 4,000 additional steps.
  • People who had a healthier, Mediterranean-type diet were found to have better physical fitness.
  • Eating healthily was associated with better metabolic health, as well.

For many people getting enough “steps in” has become part of a daily fitness goal.

So much so that everything from Google Maps to Apple Watches help us keep track of how many steps we’ve taken in a day. But new research is suggesting that what we eat can also help contribute to our daily step goals by as much as 4,000 additional steps.

The study, published in the European Journal of Preventive Cardiology, suggests that a healthy diet is associated with greater physical fitness in middle-aged adults. Study author Dr. Michael Mi box Beth Israel Deaconess Medical Center in Boston says that the study shows strong data that supports the connection between a good diet and higher fitness.

“This is an amazing community-based study design that did the most accurate way to quantify one’s [cardiorespiratory fitness] to a healthy diet via metabolite testing,” said Dr. Christopher Tanayan, Lenox Hill Hospital’s director of sports cardiology. “This is probably the most objective way to establish the association between diet and cardiorespiratory fitness. The investigators did extensive measures to remove confounding factors and adjust for biases.”

The study included 2,380 adults with an average age of 54 years. The group was split nearly down the middle between men and women. Participants underwent a cardiopulmonary exercise test on a cycle ergometer to measure peak VO2, the maximum rate of oxygen consumption attainable during physical activity.

  • Higher scores showed a better quality diet of vegetables, fruits, whole grains, nuts, legumes, fish and healthy fats, and limiting red meat and alcohol.
  • The study found that individuals with a higher dietary scores on the Alternative Healthy Eating Index and the Mediterranean-style Diet Score achieved a 5.2% and 4.5% greater peak VO2, respectively.

Tanayan pointed out that the fuel type used on test day was another data point they used in analyzing peak VO2 to confirm their dietary indices. Some metabolites were directly linked to better cardio performance.

Further analysis showed that eating healthily was associated with better metabolic health, as well.

“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,” Mi said in a statement. “The improvement in fitness we observed in participants with better diets was similar to the effect of taking 4,000 more steps each day.”

The study authors note that this is an observational study and it cannot be concluded that eating well causes better fitness, nor does it exclude the possibility of a reverse relationship.

“It’s an interesting study,” said Dr. Sean Heffron, director of fitness-focused cardiology in the Center for the Prevention of Cardiovascular Disease at NYU Langone Heart. “We’ll leave it at that. With any observational analysis, there are a lot of unmeasured confounders that are likely playing some type of role here. I would say a healthy diet and exercise are very broadly important, but how specifically a diet would contribute to improving synthesis of metabolic-related enzymes and other tissues that we know determine fitness, that I don’t know. People that eat well tend to have other good behaviors, and while the study measures a lot of different things, it does not measure everything.”

But the authors of the study were able to control for some factors by having individuals use wearable devices with step counters.

Tanayan said, “As with any other observational study that involved exercise quantification using self-reported physical activity questionnaires, there is very little one can do to remove subjectivity of a subject’s perceived daily level of activity. To lessen the effect of this, the investigators also utilized data derived from wearable devices with step counters worn for up to eight days after the test. This allows for accurate analysis of data factoring in baseline fitness derived from exercise.”

Overall, this is not the first time diet and heart health have been connected. In fact, it’s now considered a hard rule that a good diet, especially a Mediterranean-style diet, is an important part of a healthy heart and contributes to overall better fitness quality.

Heffron recommends three things to his patients with respect to diet and heart health.

“I ask them to minimize land animals because they are the major sources of saturated fat, which play a big role in LDL cholesterol levels,” Heffron said. “I tell them to put a rainbow in their tummy every day, filling their body with fruit, vegetables, and whole grains. And I ask them to eat foods that their grandparents would recognize as foods to avoid any hidden ingredients.”

“Eating a healthy diet must complement exercise, and this case may improve performance,” said Tanayan. “Adaptations in the way our heart utilizes fuel and the availability of a certain type of fuel based on one’s diet both contribute to fitness.”
