Associations between asthma and the nutritional quality of diet remain poorly understood. So they did a study 'Associations between dietary scores with asthma symptoms and asthma control in adults' which was printed in the European Respiratory Journal.
There were 34, 766 participants from the NutriNet-Santé cohort who answered a detailed respiratory questionnaire.
They investigated the connections between overall quality of diet and the asthma symptom score and asthma control. They used three dietary scores:
- the Alternate Healthy Eating Index 2010 (AHEI-2010)
- the literature-based adherence score to Mediterranean diet (MEDI-LITE)
- the modified Programme National Nutrition Santé Guideline Score (mPNNS-GS)
“A healthy diet, as assessed by the dietary scores we used, is mostly made up of a high intake of fruit, vegetables and fibre. These have antioxidant and anti-inflammatory properties and are elements in a healthy diet that potentially lower symptoms. In contrast, the least healthy diets include high consumption of meat, salt and sugar, and these are elements with pro-inflammatory capacities that may potentially worsen symptoms of asthma.”
