The phytochemicals present in apples can lower oxidative stress and inflammation found in airways, which could potentially boost respiratory function.

Bananas are packed with potassium, vitamin C and fibre, and can improve lung function.  Potassium helps the lungs contract and expand, which can prevent breathing difficulties.

Beets contain magnesium and potassium, which promote lung health. Nitrates enhance lung function, improve oxygen uptake and increase exercise capacity.  

Due to their high nutrient content, blueberries preserve and protect lung function. Anthocyanins, potent pigments found in blueberries, defend lung tissue from oxidative stress.

Brazil nuts are high in selenium which may improve respiratory performance in asthmatics. They also boost antioxidant and immune defences to improve lung health.

Carrots' potent antioxidant beta-carotene may help reduce asthma symptoms. Vitamin A supports the body's defences against harmful substances that affect the respiratory system.

Garlic reduces inflammation and its antiseptic properties support the body's defence against infections. Also, the antioxidant phytochemicals can help reduce oxidative stress in the lungs.

Ginger is anti-inflammatory, a natural cleanser and helps to clear mucus from bronchial tubes. It may aid smooth muscle relaxation in the lungs' airways, which facilitates easier breathing.

Oranges are rich in B6, Vitamin C and Iron which help produce red blood cells that carry oxygen in the body. Vitamin C can prevent and treat Acute upper respiratory tract infections.

Bromelain found in pineapple juice can aid in the treatment of asthma and allergy-related respiratory issues. It also helps break down and expel mucus.

Red capsicums' high vitamin C content helps fights free radicals and may prevent lung damage. Carotenoids help detox lungs, improve capacity and can reduce lung cancer risk.

Tomatoes contain the carotenoid lycopene, which has been linked to improved lung function and reduced airway inflammation in asthmatics and people with COPD.
