How to use food as 'medicine' during flu season.
With the flu season on the rise, maintaining a strong immune system is crucial to warding off illness. Food plays a vital role in influencing the body's immune system.
Every bite we take can either promote or worsen our health, making food a crucial component of our daily exposure, says Dr. April Wilson of Loma Linda University School of Medicine (USA).
1. The impact of food on the immune system
According to Dr. Wilson, some foods can help boost the immune system, while others can reduce the immune system's ability to respond effectively to infections.
Antioxidants and phytochemicals found in plants play a crucial role in strengthening and supporting the body's recovery. These important components are abundant in whole, colorful foods such as fruits, vegetables, legumes, nuts, and complex carbohydrates.
Maintaining a healthy diet acts as a preventative measure against disease. By consistently providing the body with essential nutrients, it helps prepare white blood cells to better respond to illness.
Consuming too many sugary foods can temporarily impair the function of white blood cells, making the body more vulnerable.
2. Incorporate immune-boosting foods
To boost your immune system, consider incorporating immune-boosting foods into your meals. Antioxidant-rich berries are a great choice, even during the colder months, or you can opt for frozen berries (instead of fresh ones). Additionally, choose foods that are colorful… as they provide a variety of nutrients to support your health.
Soups rich in vegetables and legumes are also recommended, especially in cold weather. Combining foods like garlic, onions, and berries can be particularly beneficial for children, the elderly, or those with compromised immune systems.
3. Choosing nutrients to boost immunity
The following nutrients play a crucial role in immune health:
- Beta carotene:Beta-carotene is found in plant-based foods such as sweet potatoes, spinach, carrots, mangoes, broccoli, and tomatoes.
ButVitamin C:Foods rich in vitamin C include citrus fruits, berries, melons, tomatoes, bell peppers, and broccoli.
ButVitamin D:Vitamin D is found in fatty fish and eggs. Milk and 100% pure fruit juices fortified with vitamin D are also good sources of vitamin D.
ButZinc:Foods rich in zinc include beef and seafood, but it is also found in plant sources, including wheat germ, beans, nuts, and tofu.
ButProbiotic:Probiotics are good bacteria that help boost health. It's recommended to increase your intake of fermented dairy products, such as yogurt, and fermented foods, such as kefir and kimchi.
ButProtein:Protein comes from both animal and plant sources, including milk, yogurt, eggs, beef, chicken, seafood, nuts, beans, and lentils.
In addition to a healthy diet, getting enough sleep is also crucial for maintaining optimal immune function. Ensuring you get 7-8 hours of sleep each night can significantly reduce your risk of illness.
The choices we make in our daily diet play a crucial role in determining our overall health and our body's ability to recover from illness. By prioritizing nutrient-rich foods, getting enough sleep, and adopting other healthy habits, we can strengthen our immune system to prevent illness in general and the flu in particular.
