Good nutrition is very important during the period of COVID-19 infection. The nutrient requirement increases during infection due to the following causes-

  1. To meet the body’s extra needs for energy and nutrients to fight with the disease, and it increases further when fever is present.
  2. To support immune system activity, intake of vitamins and minerals also increases.
  3. To cope up with the oxidative stress produced during COVID-19 infection, antioxidant needs also increase.

Why following a proper diet is essential for COVID-19 patients?

An appropriate diet help corona patients in the following ways-

  1. Help to manage symptoms of COVID-19 like fever, swallowing problem, dehydration etc.
  2. Improving their food tolerance
  3. Preventing severe complications like high fever, dehydration, etc.
  4. detoxifying the body.
  5. Ensuring early recovery of the patient.

What to eat when you are corona positive?

If you test corona positive, you should give more attention to your diet. Intake of a proper diet ensures early recovery.

1. Increase food acceptability

  • Since the intake of food at small and frequent intervals are better tolerated than the large meals, offer a small portion of foods at a  time and increase the number of meals. You may offer 6 small to the patients instead of 3 to 4 major meals.
  • and easy to swallow because many patients have throat pain and have difficulty in swelling.
  • If there is severe throat pain, a soft diet or semi-solid diet should be given.
  • It should be non-spicy and non-irritating to create minimum irritation in the body during food intake.
  • The diet should be bland but colorful to increase food acceptance. The patient usually has a loss of smell and taste, so colorful foods are better accepted.

2. Ensure good digestion of the patient

  • The diet should be easily digestible because such a diet is easy to assimilate
  • Fruits and vegetables containing soft fiber can be given. Fruits like a ripe banana, ripe papaya,  watermelon, pomegranate, orange, etc., and vegetables like potato, sweet potato, pumpkin, raw papaya are a good choice for corona patients.
  • Limit the intake of pulses because excess intake may cause flatulence.
  • All fried foods should be avoided as they may cause difficulty for digestion.
  • If the patient has any food allergy, it must be omitted.
  • Curds and paneer are better options for dairy products than milk because milk causes hyperacidity in susceptible individuals.

3. Ensure adequate nutrient intake

i) Energy / Calorie

The calorie requirement increases during corona diseases to cope with the high fever and overwork of the immune system of the patients.

To increase the calorie intake, 1 teaspoon of butter and 1 teaspoon of ghee can be incorporated into the daily diet of the patient. Homemade fruit juices are a good option. Cereal porridge, cereal pulse recipes like khichdi may also be given.

ii) Protein

The dietary protein should come from both animal protein (meat, fish, egg, poultry, and dairy products) and plant protein (pulses, nuts, etc.)

iii) Fat

A moderate intake of fat is good for corona patients. The dietary fat should be well-balanced and should be rich in omega-3 fatty acids (α-linolenic acid). (1)

Limited intakeExcludeComment
Vegetable oils
Butter
Ghee
Fried foods

Chips

Fat is difficult to digest.
Use only a moderate amount of
vegetable oils in cooking.

iv) Carbohydrate

Since carbohydrates are a good source of energy, they should be an integral part of the diet. Cereal grains, like rice, wheat, oats, corns, etc., are the best sources of carbohydrate rich foods. Intake of refined sugars should be reduced. Excess intake of sugar is bad for your health. Intake of high fiber foods should also be reduced because they are difficult to digest.

v) Vitamins and minerals

Vitamins and minerals play an essential role to maintain the optimum performance of our immune system. Adequate intake of vitamin-A, vitamin-B6, vitamin-B12, folic acid, vitamin-C, vitamin-D, and vitamin-E, are important. Trace elements, like zinc, iron, selenium, magnesium, and copper are also essential for rapid recovery.Omega-3 fatty acids, eicosapentaenoic acid, and docosahexaenoic acid play important roles in supporting the immune system. Inadequate intake of these nutrients and their deficient status are widespread, leading to poor resistance to infections. Dietary inclusion of foods rich in these nutrients is a safe, effective measure to support optimal immune function. (2)

  • Hydrate your body and avoid dehydration.

Hydration of the body is very important for all ages of people but it is more important for the corona positive patients because of the following reasons.

  • Water helps to regulate our normal body temperature. When body temperature rises above normal, water losses via the skin (both insensible perspiration and sweating), results in cooling of the skin. if sweat loss is not compensated for with fluid intake, it may cause dehydration. Moderate to high fever is a common symptom of COVID-19, adequate water intake is essential to cope up with the fever.
  • Adequate water intake is needed for proper digestion of the patient and prevention of constipation.
  • Inadequate water intake during diarrhoeal episodes invites dehydration and increases complications. Since diarrhea is also a symptom of COVID-19 infection, adequate hydration should be ensured for these patients.
  • For proper renal function and efficient elimination of waste material from the body, water intake should be adequate.
  • Staying well-hydrated, mainly through drinking ample amounts of plain water (6-8 glasses a day for most adults) also helps our immune system. (4)
  • During illness, increased amounts of toxins are generated. Adequate hydration ensures the flushing of toxins.

What to drink during COVID-19 illness?

To ensure adequate water and proper hydration of the body you should take various types of liquid or semi-liquid foods like chaas, buttermilk, home-made fruit juices, coconut water, etc in liberal amounts.

Soups and juices are recommended due to the following reasons-(5)

  • They prevent dehydration.
  • The fluid is better tolerated than solid foods.
  • The juice is rich in vitamins, minerals, etc. which help in the rapid recovery of the patients.
  • They are useful to reduce the severity of the symptoms like nausea, vomiting, and fever.
  • They are very helpful in maintaining the water and electrolyte balance,
  • They detoxify the body.

Limit the consumption of alcohol. Alcoholic drinks have little nutritional value, are mostly high in calories, and excess consumption is linked to numerous health problems. If you drink alcohol, do so only in moderation.

to the patient.
Mousambi or sweet lime juice  It is a rich source of potassium, copper and a fair source of vitamin C.You can give a cup of juice to the patient.
  • Increase the intake of antioxidant rich foods

The vegetarian diet is a rich source of antioxidants that protects us against chronic oxidative stress-related diseases. Plant foods contain various types of antioxidants. Antioxidants can eliminate free radicals and other reactive oxygen and nitrogen species, and these reactive species contribute to most chronic diseases. (6)

  • Include at least 2 servings of curds

Probiotics are helpful to increase our immunity. (8)

Fermented milk products like curds, buttermilk, etc are a very good source of probiotics. So, these foods should be included in the diet. Other fermented foods are idli, dosa, etc. which should also be included in the diet of COVID patients.

If patient unable to tolerate milk during fever, or if he has any gastrointestinal symptoms like diarrhoea, then buttermilk or chaas may be a good option. Make basic simple buttermilk with or without sugar as per the patient’s preference. Try giving a glass of buttermilk for better digestion, gut health, and immunity.
