New Delhi, Jul 26 (IANSlife): As we face this global pandemic, it is important that we stay indoors. maintain physical distancing and focus on building a strong immune system which is a crucial shield against infections.

While we are confined to the house, it is important we maintain a regular routine which includes daily exercise, eating a balanced diet, staying hydrated, maintaining good gut health, getting adequate sleep, and managing stress levels.

Our immune system works as the frontline defence mechanism against disease-causing microorganisms and protects us from all viruses and microbes that our body is exposed to. A healthy lifestyle along with a well-balanced diet containing all the essential macro and micronutrients is vital for optimal functioning and maintenance of the immune system.

Protein is a versatile macronutrient that sustains life and has a particularly important role to play in boosting immune function. Though we all know about the importance of protein, Indians are deficient in our protein intake. On average an individual needs 0.8-1.0g of protein per kg ideal body weight. Recommendations may vary depending on several factors such as physical activity, age, comorbid conditions like kidney disease etc. As per the General Consumer Survey (PRODIGY) conducted in 2015, 73 per cent of our population is deficient in protein intake with 93 per cent of our population being unaware of their daily protein requirements.

It is important to consume good quantity and quality of protein daily for the immune system to function at its best. A quarter of our plate at every meal must be protein.

A good quality first-class protein is one with high digestibility and has all the essential amino acids required by the body. Sources: all animal products like eggs, meat, fish, poultry, milk, milk products like curd, paneer, whey. Proteins that are partially lacking in one or more essential amino acids eg, cereals and pulses are called incomplete protein.

Combinations of foods such as cereal pulse combination like idli, dosa, Pongal, khichdi, dal rice etc. in 4:1 proportion helps improve the quality of protein in a vegetarian meal if you are unable to meet your protein requirements through diet alone, protein powders containing good quality protein can be included to bridge the gap. You can consult a qualified dietician to plan a diet tailor-made to meet your protein and nutrient requirements.

vitamins which help boost immunity

Sources of beta carotene-carrots, sweet potatoes, red and yellow peppers, tomatoes, dark green leafy veg, pumpkins, asparagus, mangoes, drumstick leaves.

Vitamin B6

Vit B6 plays an important role in supporting biochemical reactions of the immune system.

Sources: fish, poultry, nuts, chickpeas, dark green leafy veg, bananas, papayas.
