Here Are The Best And Worst Foods For Asthma, According To Science

Worst: Fast Food Severely Worsens Asthma

It’s no secret that fast food is unhealthy, but did you know that it can affect asthma? A study published in Science Translation Medicine found a strong correlation there. According to the researchers, eating fast food at least three times a week may heighten the risk of severe asthma by up to 39%.

In 2018, another study backed up these same claims. Because fast food is high in preservatives and sodium, it sucks out oxygen from the system. This “poor nutritional quality” does nothing but exacerbate asthma. Try to only eat fast food once or twice per week.
