Healthy eating increases immunity during and after COVID-19

Dairy processors will help communities thrive by bringing healthy dairy foods to market and arming customers with the information they need to improve their health and well-being.

COVID-19 is a once-in-a-generation pandemic that has had an undeniable effect on our lives. Maintaining and enhancing good health is top of mind for many as people around the world search for ways to reduce the risk of COVID-19. Handwashing, staying hydrated, and staying physically active will also help to reduce the risk of illness. Maintaining a healthy immune system is one of the strongest protections, and a healthy eating pattern will help.

Families are searching for ways to stay safe and fed in several states around the world, which offers an incentive for health practitioners and others in the dairy industry to stress the importance of maintaining a healthy immune system by eating a variety of nutritious and wholesome foods, including dairy.

Milk, cheese, and yogurt all contain vital nutrients that promote immune function, such as vitamins A and D, zinc, and protein. Within the immune system, these nutrients play specific roles:

  • Vitamin A supports the tissues of the gastrointestinal tract and respiratory systems.
  • Vitamin D plays a role in the gastrointestinal tract and protects against lung infections.
  • Zinc helps with immune system function and the maintenance of skin integrity.
  • Protein aids in healing and recovery.

Beyond the effects of individual nutrients, research shows that dairy foods such as milk, cheese and yogurt contain a unique package of nutrients that work together to enhance health benefits. Scientific research continues to link milk and dairy food consumption, when part of a healthy eating pattern, to a wide range of health benefits, including blood pressure control, improved bone health, reduced risk of type 2 diabetes and heart disease, and better weight management. For children and adolescents, consuming dairy foods plays an important role in supporting optimal growth and development.

Probiotics and health

Fermented dairy foods such as yogurt and certain cheeses contain probiotics, which are live bacteria in food that are noted for their positive impact on gut health. Research shows that eating yogurt and other fermented foods rich in probiotics may help improve immunity and reduce inflammation.

A scientific study found that the number of upper respiratory infections and flu-like symptoms in adults was reduced after they consumed probiotic-rich yogurt drinks. Another study found that preschool-age children whose diets included daily probiotics experienced reduced cold and flu symptoms, resulting in fewer school absences.

Probiotics found in foods can support not only physical health, but also mental wellbeing. Studies are examining probiotics and their possible health benefits, including the ability to reduce anxiety, relieve stress and improve mental outlook.

Given the current pandemic, we are living in a highly stressful and uncertain time. Prioritizing mental, physical and emotional health and self-care, including food choices, can play an important role in staying healthy and getting through this difficult time.

Encourage healthy eating patterns

Encouraging consumers to build eating patterns that consist of nutritious and wholesome foods will help support their health and wellbeing during this global health crisis and beyond. Healthy eating patterns are built on daily food and beverage choices.

Health experts encourage consumers to eat nutrient-dense foods such as milk, cheese, yogurt, vegetables, fruits, whole grains, beans, nuts, seeds, fish, lean meat, poultry, eggs and healthy fats and oils, while limiting or avoiding refined starches, added sugars, processed meats and other highly processed foods.

The current pandemic is also exacerbating food insecurity in communities as families are forced to stretch their food dollars further. Fortunately, healthy food choices can still fit within a budget, and many community resources are available to assist families in accessing nutritious foods. It is important to provide consumers with information to help them make budget-friendly food choices that can support health year-round.

As a dairy community, we have an important role to play. Dairy processors can support community health by bringing nutritious, wholesome and affordable dairy foods to the market and by empowering consumers with information needed to support and positively impact their health and wellbeing.

All of us can share information with our networks about the importance of consuming a healthy, balanced diet, which includes milk and dairy foods. Information can be shared directly and through traditional communication channels, social media and in marketing and promotion efforts.

Dairy consumption is supported by nutrition science, and emerging research continues to support dairy’s role in healthy eating patterns. As industry leaders, we can help inform policy development by sharing updates on dairy’s role in daily eating patterns as supported by nutrition science and by elevating the nutritional needs of children for optimal growth and development. By doing these things, I believe we as a dairy community can continue to successfully support community health and elevate the health of children and families during COVID-19 and beyond.
