Food as Medicine

Food as Medicine: Why Personalized Clinical Nutrition Is Becoming the Future of Healthcare

Dr. Nayera Masoodi



For many years, medicine has been primarily oriented around disease diagnosis and treatment. However, one of the most powerful therapeutic tools has been overlooked and that is food. In today’s day and age, the science of nutrition and precision medicine and healthcare technology is changing the way we look at nutrition. Food is no longer only considered as a source of energy but as a highly effective medicine both for prevention and treatment.

This change is one of the biggest changes in modern healthcare. Healthcare institutions, clinicians and policy makers worldwide are starting to understand the potential of personalized clinical nutrition for better patient outcomes, lower health care costs, decreased hospital stays, and higher quality of life.

Beyond One-Size-Fits-All Nutrition

The traditional guidance on nutrition has been very regimented. These are good but do not capture the vast inter-individual variation. Nutrition needs are influenced by age, genetic makeup, health conditions, allergies, gut microbiota, medications, metabolism and lifestyle.

For a child healing from an operation, an elderly diabetic, a cancer patient on chemotherapy, and a premature baby, the nutritional approach is completely different. These differences are recognised in personalised nutrition, which involves creating dietary interventions according to the individual patient’s physiological and clinical requirements.

Healthcare professionals are no longer asking about “What is a healthy diet?,” but rather “What is the healthiest diet for this particular patient?”.

The role of clinical nutrition is getting more and more significance.

Malnutrition is one of the most underdiagnosed problems in the world today in the hospital setting. Studies have long shown that many hospitalized patients have nutritional deficiencies that slow healing, compromise their immune system, raise the incidence of infection and extend recovery.

So, clinical nutrition is not a luxury service anymore, but rather an integral part of evidence-based health care.

Comprehensive nutrition care process includes:

• Early nutrition risk screening.
• Detailed nutrition assessment
• Individualized meal planning
• Continuous monitoring
• Outcome evaluation
• Interdisciplinary team approach by physicians, dietitians, nurses, and foodservice staff.

The greater the incorporation of nutrition into clinical decision making, the better the results for patients.

Pediatric Nutrition: Building Health from the Beginning

Growth and development happen at the same time as the child is recovering from disease, so their nutritional needs are different from those of adults. Short-term malnutrition in childhood can impact physical growth, immunity, cognition and future health.

Personalised paediatric nutrition helps infants and children to obtain the right nutrients for their stage of development, medical condition, food allergies and metabolic needs.

In the field of neonatal intensive care, paediatric wards and outpatient clinics, nutrition therapy has been a vital component of quality healthcare and is now an essential part of the treatment of the individual patient.

Food Allergies Need More Attention

Millions of children and adults around the world suffer from food allergies and the prevalence of food allergies has grown significantly in the last two decades.

With hospitalized patients, food allergy management goes beyond not eating certain ingredients. Rigorous quality assurance systems must be put in place in hospitals, which should include:

• Proper patient allergy record keeping.
• Leaving the school.Proper food preparation.
• Cross-contamination prevention
• The level of staff education and training.
• Continuous quality monitoring

All of these protections are necessary if they are not provided vulnerable patients are at serious risk.

Hospital Food Is Healthcare

Food served in hospitals is perceived as less expensive than it actually is. They are however, an important treatment measure.

A nutritionally balanced, hygienically prepared, patient-centred meal would help to:

• Faster wound healing
• Better medication tolerance
• Improved immune response
• Reduced complications
• Enhanced patient satisfaction
• Lower readmission rates

Quality hospital foodservice is thus more than just a way of getting food to a patient’s mouth, it is integral to healthcare service.

Healthcare facilities need to invest in QA systems and ensure that the food provided is both nutritionally adequate and safe, that the patient is satisfied, and that the system is continually improved.

Technology is changing the way nutrition care is delivered.

• AI, wearable health devices, digital health records and nutrition analytics are transforming dietetic practice.
• With the help of emerging technologies, healthcare professionals are now able to:
• Track real-time nutrition consumption
• Predict malnutrition risk using AI algorithms
• Create individual nutrition plans.Design individualized meal plans.
• Use digital platforms for tracking recovery
• Improve the efficiency of the hospital foodservice system
• Minimize food waste by forecasting needs

Technology is not meant to replace a nutrition professional, it’s meant to supplement their ability to make accurate, evidence-based decisions.

Sustainable lifestyles are integral to good nutrition.Good nutrition is part and parcel of sustainable lifestyles.

Healthcare systems are also getting on board with sustainable nutrition practices.

Hospital foodservice that’s “green” consists of:

• Seasonal food sourcing
• Reduced food waste
• Sustainable procurement
• The options for a balanced plant-based meal.
• Efficient kitchen management

These practices are not only useful in the treatment of patients but also help maintain environmental sustainability, which is a part of the public health agenda.

The Future of Nutrition lies in Precision Nutrition

The next step in healthcare—Precision Nutrition—Incorporating genomics, metabolomics, microbiome science, and artificial intelligence to create highly personalized nutritional interventions.

In the future, the genetic profile, microbiome profile, and metabolic signature of each patient could be used routinely to guide nutrition prescriptions within hospitals as routinely as medications.

These innovations can revolutionize the prevention of disease, the management of chronic conditions and personalized medicine.

A Call to Action

Nutrition must not be an ancillary service in healthcare. It is a fundamental aspect of prevention, treatment, recovery and long-term health.

Building up clinical nutrition services needs cooperation between health care professionals, hospital administrators, teachers, researchers and policymakers. Quality assurance, evidence based nutrition, technological innovation, and patient centered nutrition care investment will ultimately lead to healthier hospitals and healthier communities.

In an era of continuing change in the healthcare sector, there is one thing that remains constant: food is not just fuel, it is one of the most potent medicines that can be readily obtained. With personalized clinical nutrition and strong hospital foodservice systems, the future of healthcare nutrition could be a future where every patient gets a meal customized to their needs, where nutrition is a central element of quality care to all healthcare institutions, and where every meal has a positive impact on healing.
