New Delhi: Preventing H1N1, commonly known as swine flu, involves more than avoiding exposure to the virus. Hand hygiene, masks and other precautions can
reduce the risk of infection, but overall health also influences how the body responds to illness. Nikita Garg, nutritionist, explains to News9 Digital how everyday dietary and lifestyle habits can support immune function.
She highlights the importance of adequate protein, essential vitamins and minerals, gut health and sufficient sleep. However, the nutritionist also stresses that immunity cannot be strengthened through a quick fix or a single “antiviral” food. Instead, consistent nutritional and lifestyle habits form the foundation of a healthy immune response.
Include adequate protein in your diet
Immune cells and antibodies depend on proteins and their building blocks, amino acids. Garg recommends including adequate protein through foods such as paneer, eggs, curd and other suitable protein sources.
“A diet dominated by carbohydrates can provide energy, but it may not provide enough protein for the body’s needs. Including adequate protein regularly is important for supporting normal immune function,” Garg explains.
Protein requirements vary between individuals, so the appropriate intake should be based on factors such as age, body weight, health status and activity levels.
Don’t overlook vitamins and minerals
Several micronutrients play important roles in normal immune function. Vitamin D, vitamin A and zinc are among the nutrients Garg highlights.
“Vitamin D plays several roles in immune function, while vitamin A supports the body’s mucosal barriers and zinc is involved in the development and functioning of immune cells,” the nutritionist says.
She recommends checking vitamin D levels when appropriate and taking supplements only after consulting a doctor, rather than self-medicating.
Gut health and sleep matter too
Dietary patterns can also influence overall health and immune function. Garg advises limiting excessive intake of added sugars and alcohol while maintaining a balanced diet.
Sleep is another important part of immune health. Adequate sleep supports normal immune responses, while consistently poor sleep can affect the body’s ability to respond to infections.
Immunity cannot be built overnight
No food or supplement can instantly strengthen immunity or prevent H1N1. A balanced diet, adequate sleep, regular physical activity and appropriate preventive measures work together to support overall health.
The focus, therefore, should be on building sustainable habits rather than looking for a single “antiviral” food or overnight solution.
