The body wards off respiratory illnesses in a variety of ways. Now researchers are exploring the role the digestive system plays in lung health. They are particularly interested in how food influences the microbiota—bacteria, viruses and fungi—that naturally inhabit the human body.

There are a number of ways to fight off respiratory ailments. One that may surprise you is diet.
Although they’re made up of separate organs, the gastrointestinal tract (GIT) and respiratory tract have a close partnership. The respiratory system delivers oxygen to the blood, which is used by the GIT to digest food. In turn, the GIT provides fuel for the lungs to do their work.
What you eat can affect how your lungs perform

The GIT is filled with a diverse universe of microbiota performing many functions, including regulating the immune system and protecting against harmful pathogens. Studies have shown that some changes in microbiota are linked to inflammation, disease development in the lungs and changes in immune responses. However, a healthy intestinal microbiota maintains a steady immune response—one reason there’s an interest in the probiotics in foods like yogurt to help keep the microbiota in balance.
If the microbiota is thought of
as an ecosystem, the nutrient-
poor lungs are like a desert,
but the nutrient-rich
intestines are like a rainforest.

the role of food
Fatty, fried or spicy foods, as well as alcohol and coffee, can trigger acid reflux, a condition where stomach acids travel up the esophagus to the throat. If the liquid makes it into the airway and enters the lungs, it can cause coughing, hoarseness, shortness of breath or even pneumonia. Symptoms of acid reflux include heartburn, burping and food regurgitating into the throat. The risk increases with obesity or smoking. To lessen acid reflux, eat slowly and moderately and finish eating at least three hours before sleeping. Other respiratory ailments may also be helped by food.
Tips to help reduce the risk of respiratory ailments.
What to limit
SULFITES
in shrimp, maraschino cherries, bottled lemon and lime juices, alcohol and some pickled foods can cause asthma symptoms.
GAS-CAUSING FOODS
such as carbonated drinks, beans, garlic, onions and fried food can make breathing more difficult.
CARBS
use more oxygen and produce more carbon dioxide during digestion than healthy fats.
FRIED FOODS
may cause bloating by pushing on the diaphragm and making breathing uncomfortable.
SALT
contributes to water retention; excess water can lead to breathing problems.
ACIDIC FOODS
such as citrus, fruit juice, tomato sauce, coffee and spicy food may bring on acid reflux.
Respiratory infections
Vitamin D, often in fatty fish, could boost the immune system and help reduce inflammation of airway passages. And research indicates vitamin D supplements may have a protective effect against acute respiratory infections.
Vitamin C, found in fruits and vegetables, may help protect the lungs and reduce the risk of developing chronic obstructive pulmonary disease, or COPD, according to research.
COPD
Asthma
Vitamins D and E, from nuts and seeds, may decrease the risk of developing asthma symptoms such as coughing and sneezing. Vitamin E contains a chemical compound called tocopherol, shown to have a beneficial effect. Low levels of vitamin D have been linked to a higher risk of asthma attacks.
reduce stress
Stress can hinder digestion, weaken the immune system and increase inflammation.
Deep breathing calms the mind and body by creating a relaxation response.
Being in nature for just 20 minutes can help lower stress hormone levels.
Regular exercise can improve mood and lower symptoms of anxiety.
Laughing increases oxygen levels and stimulates heart, lungs and muscles.
Apples & pears
are full of fiber, which may improve lung function.
Berries
have manganese, which helps calcium absorption and blood sugar regulation.
Broccoli
contains vitamin C and sulforaphane, which may help prevent cancer.
Garlic
contains the compound allicin, shown to be effective against viruses.
Ginger
protects lungs from severe damage caused by inflammation.
Turmeric
contains curcumin, an antiviral, antibacterial
and antifungal.
