Corona Virus In Young Patients And Kids

Kids seem to be relatively unaffected by COVID, but this does not mean they are invulnerable. As with adults, some children have pre-existing cardiac, respiratory, or metabolic conditions, and are therefore more vulnerable to the effects of COVID. Interestingly, children appear to have one more symptom when infected with coronavirus – COVID Toes.

I personally came across this phenomenon recently, with a young patient asymptomatic for COVID who presented with unusual symptoms of dark bruises on his toes. This had been present for just a few days. He did not have any pain, itching, swelling, no recent trauma, or injury to the feet. Circulation to his feet was normal, with no other rashes or skin changes, no other abnormal features in the history to note. It was certainly an odd presentation and certainly could have been an example of COVID toes.

This new phenomenon was noticed in April and has not gained as much notoriety because it is fairly rare compared to the major COVID symptoms, such as fever, cough, and lethargy.  Doctors have described lesions on the feet of young people, usually purple-colored, around the tips of the toes. They have been compared to chilblains, painful swellings on feet, and toes that appear in the cold. Similarly to chilblains they do not cause any permanent damage and usually regress in days to weeks.

It's not clear why they occur or the mechanism behind the discoloration, because the presentation is rare and in healthy patients. We know COVID can cause systemic inflammation and can increase the risk of clot formation. It may be that localized inflammation is occurring in the toes, causing the vessels to clamp down and reduce blood flow to the area. This is similar to the mechanism for chilblains forming in the foot. Micro-clotting could also be partially responsible for this phenomenon.

COVID Toes is not the only skin symptoms related to COVID. In a paper published in the British Journal of Dermatology, researchers described five common skin presentations in 375 COVID patients. These were:

  • Asymmetrical chilblain like lesions in the hands and feet, found in younger patients lasting up to 2 weeks.
  • Small itchy blisters in the trunk and limbs, found in middle-aged patients before they present with symptoms, lasting about 10 days
  • Pink or white areas of raised skin, itchy, usually on the body
  • Raised bumps called macropapules, lasting about a week, seen in more severe infections.
  • Mottled, blotchy red-blue skin (known as livedo) seen in patients with severe illness.

So if you are currently suffering from COVID or have recently recovered from an infection, and suddenly notice odd colored toes, you too may have a case of COVID toes.

Role of Nutrition in Disease Prevention: How Food Choices Shape Long-Term Health

Role of Nutrition in Disease Prevention: How Food Choices Shape Long-Term Health

Disease prevention is no longer limited to vaccinations and medical screenings. Modern healthcare increasingly recognises nutrition as one of the most powerful tools for preventing illness before it begins. The role of nutrition in disease prevention is especially important in India, where lifestyle-related diseases account for a large share of premature illness and mortality.

According to the Indian Council of Medical Research (ICMR) and the National Family Health Survey (NFHS-5), poor dietary patterns contribute significantly to rising cases of diabetes, heart disease, obesity and hypertension. Unlike genetic factors, nutrition is a modifiable risk factor, meaning everyday food choices can actively protect health.

 


Why Nutrition Is Central to Disease Prevention

1. Nutrition regulates metabolic health

Balanced diets help maintain:

  • healthy blood sugar levels
     

  • optimal cholesterol balance
     

  • stable blood pressure
     

Disruption in these systems increases disease risk.

2. Nutrition strengthens immunity

WHO highlights that immune function depends heavily on adequate intake of vitamins, minerals and protein.

3. Nutrition controls inflammation

Chronic low-grade inflammation is linked to most lifestyle diseases. Diets rich in whole foods reduce inflammatory markers.

Major Diseases Influenced by Nutrition

Diabetes and Prediabetes

Excess refined carbohydrates and sugar drive insulin resistance.

Preventive nutrition focuses on:

  • whole grains
     

  • fibre-rich vegetables
     

  • adequate protein
     

  • controlled portion sizes
     

ICMR data shows that dietary modification can delay or prevent type 2 diabetes in high-risk individuals.

Cardiovascular Disease

Heart disease remains a leading cause of death in India.

Nutrition impacts:

  • cholesterol levels
     

  • blood pressure
     

  • arterial inflammation
     

Diets low in trans fats and high in fibre significantly reduce cardiovascular risk, as confirmed by WHO and Lancet studies.

Obesity

Obesity increases the risk of multiple chronic diseases.

Preventive nutrition addresses:

  • calorie density
     

  • food quality
     

  • satiety regulation
     

NFHS-5 reports a steady rise in overweight and obesity across age groups.

Hypertension

High sodium intake and low potassium intake contribute to high blood pressure.

Preventive dietary strategies include:

  • reducing processed foods
     

  • increasing fruits and vegetables
     

  • maintaining mineral balance
     

Certain Cancers

Diet influences cancer risk through:

  • antioxidant intake
     

  • fibre consumption
     

  • reduced exposure to carcinogenic compounds
     

WHO estimates that a significant percentage of cancers are preventable through diet and lifestyle changes.

Key Nutrients That Support Disease Prevention

Fibre

Supports gut health, blood sugar control and cholesterol reduction.

Protein

Essential for muscle health, immune function and metabolic balance.

Healthy Fats

Omega-3 fats reduce inflammation and protect heart health.

Micronutrients

Iron, zinc, vitamin D and B vitamins are essential for metabolic and immune regulation.

NFHS-5 highlights widespread micronutrient deficiencies in India, increasing disease vulnerability.

Role of Gut Health in Prevention

The gut microbiome plays a major role in:

  • immune regulation
     

  • inflammation control
     

  • nutrient absorption
     

Fermented foods and fibre-rich diets support healthy gut bacteria, strengthening disease resistance.

 

Why Preventive Nutrition Works Best Early

Nutrition is most effective when applied:

  • before disease onset
     

  • during pre-disease stages
     

  • alongside regular health screening
     

Once disease progresses, nutrition remains supportive but may not reverse damage fully.

Nutrition vs Medication in Prevention

Medication treats disease; nutrition reduces risk.

WHO and NITI Aayog emphasize that:

  • preventive nutrition reduces disease incidence
     

  • lifestyle modification lowers healthcare burden
     

  • early nutrition changes reduce dependency on long-term medication
     

Both approaches work best when combined appropriately.

Workplace and Community Role in Preventive Nutrition

Structured nutrition programs at workplaces and communities:

  • improve awareness
     

  • support behaviour change
     

  • reduce population-level disease burden
     

Lancet studies show that group-based nutrition interventions improve long-term adherence.

 

Common Myths About Nutrition and Disease Prevention

Myth 1: Supplements replace healthy food

Whole foods provide better long-term protection.

Myth 2: Prevention requires extreme diets

Consistency matters more than restriction.

Myth 3: Nutrition only matters after diagnosis

Early nutrition is most effective before disease develops.

Building a Preventive Nutrition Routine

Effective preventive nutrition includes:

  • regular meals
     

  • diverse food groups
     

  • portion awareness
     

  • minimal processed foods
     

  • hydration
     

Small daily choices compound into long-term health benefits.

Long-Term Impact of Preventive Nutrition

Consistent healthy eating leads to:

  • reduced disease risk
     

  • improved energy and productivity
     

  • better immune resilience
     

  • lower healthcare costs
     

  • improved quality of life
     

NITI Aayog identifies nutrition as a cornerstone of sustainable healthcare systems.

Conclusion

Understanding the role of nutrition in disease prevention empowers individuals to take control of their health long before illness develops. Balanced, consistent nutrition reduces inflammation, supports immunity and protects against chronic diseases that burden India’s healthcare system. Preventive nutrition is not about short-term fixes but about building lifelong habits that support health, resilience and longevity.
