Nutrition for illness recovery: What to eat while recovering from illness?

In these difficult times where the COVID-19 pandemic is affecting many…

You may get asked this question a lot by your clients and family.

So, what are the best nutritional strategies and foods to incorporate into the diet of someone who is recovering from illness, in particular a viral infection?

Here’s a quick guide to walk you through the fundamentals:

Rehydration

Fever can be very dehydrating.

The higher your body temperature, the more dehydrated you may become.

Dehydration is categorised as mild (3% to 5%), moderate (6% to 10%), and severe (more than 10%).

Since re-hydration is the number one priority, drinking plenty of fluids is essential.

Electrolyte Replenishment

In addition to sipping water regularly, we need to replenish electrolyte losses – that is, salts and minerals like potassium.

This can be helped by having foods with a high water and electrolyte content like berries, oranges, melons, and cucumber, in addition to beverages like broth, herbal teas, or coconut water.

Because these are more palatable than water on its own, they can help rehydrate more effectively, too.

How Much Protein?

Muscle loss during illness is a side effect we shouldn’t ignore and it often translates to generalised weakness.

Calorie and protein requirements during recovery are usually higher than your regular intake.

Depending on the illness severity, daily protein needs go up to over 0.8 grams of protein per kilogram of body weight in mild cases and over 1.2 grams of protein per kilogram of body weight in the severely ill.

Therefore, besides re-hydration, foods with a high protein content need to be prioritised.

These include chicken, eggs, and fish, as well as plant foods like beans, lentils, quinoa, rice, and hulled hemp seeds, which also contain some carbohydrate aiding protein uptake by muscle and organ tissues.

A number of scientific studies found that nutritional supplementation in older patients after being hospitalised, in particular complete amino-acid supplementation, may aid recovery and increase physical strength.

Which Vitamins and Minerals?

What are some of the best vitamins and minerals that can help someone to recover from illness?

All essential vitamins and minerals in the right amounts are needed for a full recovery.

But depending on the cause of the illness, some of them may be needed in higher quantities.

For example, some essential micronutrients may be used and depleted faster when the immune system is fighting a viral infection, in particular vitamins C, D, and A, and minerals like zinc, iron, selenium, and chromium.

Upping our intake of fresh produce like fruits, vegetables, herbs, legumes, grains like rice and oats, and seeds can be very helpful during recovery from a viral infection.

Prebiotics and Probiotics

Gastrointestinal disturbances are also common during illness.

In addition, this can be exacerbated when antibiotics and antiviral medications are taken.

Incorporating prebiotics can be helpful, in particular fermentable fibre, which feeds ‘good’ gut bacteria (from grains like oats, allium vegetables like onions, and fruits like bananas), as well as probiotic-rich foods such as fermented vegetables like sauerkraut and miso.

Tackling Appetite Loss

A common problem is that during illness and recovery, appetite tends to go down and taste changes, with some reports suggesting that it may take 28 days for hunger hormones to return to their normal levels after critical illness.

Going back to eating normally can be further worsened by gastrointestinal disturbances, swallow disfunction, and poorer chew strength.

For these reasons, each eating episode is a golden opportunity to get the right nutrients into a body that is still recovering.

However, when each bite we take feels like a tremendous effort, it’s important to go for softer textures by pureeing and blending foods into soups and nutrient-packed smoothies.

This way, we can take in more food and more nutrition, but with less effort. And this is critical during recovery.

[CPD Certified Webinar] Plant-Forward Nutrition Strategies to Support Your Clients

Plant-based eating appeal is on the rise, with personal and planetary health being the key motivators. More of us just seem to want a healthier planet whilst feeling healthier ourselves.

But what is plant-based eating – and what is it not? Does it allow for some animal foods… or is it about going entirely vegan?

In this webinar, we put an end to this debate by revealing our groundbreaking 10-level framework for transitioning from plant-rich, to plant-based, to possibly plant-exclusive, in a way that respects each of your client’s needs and self-determined goals. We will also show you impactful strategies to support your clients’ interest in eating more plant foods and how facilitate plant-forward eating behaviour change, the right way.

We’ll also answer the question: Are all plant-food diets healthy?

Although research has related plant-based diets with health advantages and overall disease risk mitigation, going exclusively plant-based (especially when done wrong) carries dangerous risks – from gastrointestinal disturbances to 'vegan insomnia', tiredness and brain drain, to overeating or undereating, panic about shopping/food preparation, harmful dietary insufficiencies, … and the list goes on.

So, what’s the right way of helping a client mitigate these problems? How might you support a smoother plant-eating transition without fears and unwanted complications?

Completing this CPD-certified training will equip you with vital know-how underpinning plant-forward nutrition client practice, alongside insights about adequately building personalised plant-focused dietary plans that clients love and can keep up with.

Here’s an overview of what you’ll discover in this special CPD certified webinar:

  • From planetary health to human health: learning about the World Health Organization’s ‘One Health’ model
  • What is plant-based eating, what is it not, and how to put an end to this debate with a ‘plant-forward mindset’
  • Importance of transitioning from plant-rich, to plant-based, to possibly plant-exclusive in a way that respects your clients’ needs and self-determined intentions
  • Plant-based gone wrong: uncovering the dangerous physical and mental health risks of going exclusively plant-based – and how to prevent them
  • Advantages of becoming an Advanced Plant-Forward Nutrition Specialist™ and integrating plant-eating behavioural-change strategies into your work with our NEW Level 5 Certification

How to proficiently support your clients’ plant-forward dietary enhancements by applying the groundbreaking 10-level nutrition client framework (which is proprietary to The Health Sciences Academy and validated by world-leading researcher Dr David Katz and the True Health Initiative – to be revealed for the first time in this exclusive webinar)
