While medical treatments, including augmentation therapy, can help manage Alpha-1, diet also plays a critical role in reducing inflammation and supporting overall health. In this article, we’ll explore how inflammation plays a role in Alpha-1, and how a nutrient-rich diet can help individuals reduce inflammation, improve their immune system, and potentially manage Alpha-1 symptoms more effectively.

What Role Does Inflammation Play in Alpha-1 Antitrypsin Deficiency?

Alpha-1 antitrypsin (AAT),  also called “alpha-1 proteinase inhibitor” or “aPi,” is a protein primarily produced in the liver. AAT’s primary role is to protect the body’s tissues from damage caused by proteolytic enzymes, which break down proteins. Inflammation plays a key role in the body’s defense against infection. When the body encounters harmful agents like bacteria or viruses, the immune system is activated, triggering an inflammatory response. This process sends signals to white blood cells and other immune components to help fight off the invaders.

Neutrophils, a type of white blood cell, are among the first responders in this inflammatory process. They release proteolytic enzymes, including one called “neutrophil elastase,” to break down and eliminate the threat. However, during inflammation, these enzymes can also damage healthy tissues if not properly regulated.

Normally, AAT helps maintain a balance by protecting tissues from the destructive effects of neutrophil elastase and other enzymes during inflammation. In people with low AAT levels, this protective mechanism is weakened, leading to increased tissue damage and a higher susceptibility to diseases associated with Alpha-1 antitrypsin deficiency. In these individuals, inflammation can trigger more harm than protection, as the body’s defenses lack sufficient AAT to control the excess activity of proteolytic enzymes.

How to Reduce Inflammation Though Diet

1.  Eat Anti-inflammatory Foods 

A healthy, anti-inflammatory diet can help reduce the body’s chronic inflammatory response, benefiting those with Alpha-1. Here are some key foods known for their anti-inflammatory properties:

  • Fatty fish (omega-3s): Omega-3 fatty acids are well-known for their ability to reduce inflammation. Fatty fish, such as salmon, mackerel, sardines, and trout, are rich in omega-3s, which help decrease the production of inflammatory molecules in the body. For those with Alpha-1, incorporating these fish into the diet can be particularly beneficial for managing inflammation in the lungs and other organs. Aim for at least two servings of fatty fish per week.
  • Fruits and vegetables (rich in antioxidants): Fruits and vegetables, especially those with bright colors, are packed with antioxidants that fight inflammation. Berries, such as blueberries, strawberries, and raspberries, are particularly high in antioxidants, as are leafy greens like spinach and kale. Tomatoes, sweet potatoes, and bell peppers are also great sources of vitamins and antioxidants that support immune function and reduce oxidative stress. Try filling half of your plate with colorful fruits and vegetables at each meal.
  • Turmeric and ginger: Both turmeric and ginger have long been used for their anti-inflammatory effects. Curcumin, the active compound in turmeric, can help block inflammatory pathways in the body. Similarly, ginger contains bioactive compounds that reduce inflammation and alleviate discomfort. Incorporating these spices into meals or as part of smoothies or teas may provide significant benefits. You can add 1–2 teaspoons of turmeric or ginger to your daily meals, or enjoy a cup of turmeric or ginger tea.
  • Nuts and seeds: A diet rich in nuts like walnuts and almonds has been found to reduce inflammation, insulin resistance, and oxidative stress, and may even help those with fatty liver disease improve liver function.
  • Olive oil (monounsaturated fats): Extra virgin olive oil is rich in monounsaturated fats and contains oleocanthal, a compound that has anti-inflammatory properties similar to those of ibuprofen. Using olive oil as your primary cooking fat or in salad dressings can help lower inflammation levels in the body. Try using 1–2 tablespoons of extra virgin olive oil daily in cooking or as a dressing.

2. Avoid Certain Foods That Can Cause Inflammation

Just as some foods can help reduce inflammation, others may increase it. For individuals with Alpha-1, it’s crucial to avoid foods that can exacerbate inflammation, particularly those that contribute to oxidative stress and immune system imbalances.

  • Processed and red meat: Processed meats (such as bacon, sausage, and hot dogs) and high-fat red meats can increase inflammatory markers in the body. These foods are also linked to a higher risk of heart disease and may contribute to lung complications, making them a less-than-ideal choice for individuals with Alpha-1. Limit red meat consumption to occasional servings, and opt for leaner cuts when possible.
  • Refined carbohydrates and sugars: Foods high in sugar and refined carbohydrates (such as white bread, pastries, and sugary snacks) can trigger inflammation by increasing insulin levels and promoting oxidative stress. These foods can also contribute to weight gain, which may worsen symptoms of Alpha-1, especially those related to the lungs.  Choose whole grains like brown rice, quinoa, and oats instead of refined carbs, and reduce intake of sugary foods and drinks.
  • Trans fats and fried foods: Trans fats, often found in processed foods like packaged snacks, fried foods, and some margarines, have been shown to increase inflammation. These fats can worsen overall health and contribute to systemic inflammation, which may exacerbate the lung and liver complications associated with Alpha-1. Avoid trans fats by checking food labels and opting for healthier fat sources like avocados, nuts, and seeds.

3. Eat Foods that Support Liver Health

A healthy liver is vital for filtering toxins and managing overall health, and certain foods can help protect and support liver function.

  • Cruciferous vegetables: Vegetables like broccoli, cauliflower, Brussels sprouts, and cabbage contain compounds that help the liver detoxify harmful substances and reduce inflammation. These veggies are also rich in fiber, which supports digestion and gut health.
  • Oatmeal: The fiber in oatmeal helps aid digestive function.
  • Beans: High in protein and fiber, beans are a great low-fat way to get essential nutrients.
  • Soy: Soy products like tofu contain high amounts of the protein β-conglycinin which has been shown to help lower triglyceride levels and possibly protect against visceral fat buildup.
  • Berries: Dark berries like blueberries, cranberries, and raspberries contain polyphenols which are antioxidants that may help protect the liver from damage.
  • Grapes: The high level of antioxidants in whole grapes may help prevent damage to the liver.
  • Green tea: Green tea is rich in catechins, which are antioxidants that have been shown to help reduce liver inflammation and protect liver cells from damage. Drinking green tea regularly may offer additional protection to the liver, especially for those with Alpha-1.

4. Follow Additional Tips for Reducing Inflammation

  • Stay hydrated: Staying hydrated is essential for reducing inflammation and supporting overall health. Water helps flush toxins out of the body and maintains healthy tissue function.
  • Manage your weight: Maintaining a healthy weight can reduce systemic inflammation. Extra weight, particularly abdominal fat, contributes to inflammation and can worsen Alpha-1 symptoms.
  • Exercise regularly: Regular moderate exercise may help reduce inflammation by improving the body’s immune response
  • Maintain proper oral health: Bacteria in the mouth can lead to inflammation of the gums and even lead to heart and lung infections
  • Consider omega-3 supplements: If you have difficulty getting enough omega-3s through food, consider an omega-3 supplement. These supplements can provide the anti-inflammatory benefits of fish without needing to eat large amounts of fish. Consult your healthcare practitioner before adding any supplements to your diet.

While managing alpha-1 antitrypsin deficiency requires a comprehensive approach, a diet rich in anti-inflammatory foods and low in inflammatory ones can help reduce inflammation in the body, support lung and liver health, and improve quality of life. 

Always consult with a healthcare provider or dietitian before making significant changes to your lifestyle or diet, especially if you have a chronic health condition like Alpha-1.
