Low Carb Diets and Asthma: A review

article An analysis of the data from over 5,000 clinical trials suggests that a low carbohydrate (LC) diet has been shown to decrease the risk of developing asthma in patients with chronic bronchitis, but this does not apply to asthma patients with non-COVID-19-associated asthma.

A number of previous reports have shown that a reduction in carbohydrate intake from 30% to 15% of daily calories, or less, may have some impact on asthma outcomes.

To help clarify the role of carbohydrate in the pathogenesis of asthma, we reviewed the literature on the effects of a low carb diet in asthma patients.

A low carb high fat diet reduces asthma-related inflammation and oxidative stress, while increasing circulating levels of the cytokines IL-10, TNF-α and IL-1β.

This has been well-established as a key mechanism of asthma development.3 Low carbohydrate diets are also reported to reduce oxidative stress and inflammation, as well as to reduce inflammation, oxidative stress induced cell death, and oxidative damage.4 However, our findings suggest that the relationship between carbohydrate intake and asthma-associated outcomes may vary depending on the type of disease.

This suggests that we should not rule out the possibility that the association between dietary carbohydrate and asthma may be more complex than previously thought.5
