The Connection Between Nutrition and Work Performance

Written by: Kiara Lipschitz

Can what you eat affect how you perform at work?

In an era where workplace wellness initiatives are gaining traction and personalised health services like OptimallyMe are on the rise, the link between nutrition and work performance is a topic of increasing interest.

We’ll look at the science behind nutrition's impact on work performance, examining the metrics used to measure this relationship, the factors that influence individual performance, and the broader implications of this connection. 

1.Nutrition and Work Performance

The impact of nutrition on work performance is often measured through metrics like productivity, cognitive function, and overall wellness.

For instance, a study by Brigham Young University found that employees who predominantly consume unhealthy foods are 66% more likely to experience productivity loss.

Furthermore, proper nutrition has been linked to increased cognitive function , better concentration , and heightened self-esteem , all of which can contribute to improved work performance.

Also, proper nutrition and a healthy lifestyle has been found to improve work performance, and most notably absinthism .

However, it is important to mention that individual responses to nutrition and nutritional changes can vary, and these measurements may not fully capture the complexity of the relationship between nutrition and work performance.

For example, dietary restrictions, food sensitivities, and unique health needs can all influence an individual's nutritional choices and their impact on work performance.

While these metrics provide valuable insights, they should be interpreted with caution and within the context of the employee’s individual health needs and circumstances, hence why it’s so important to have a personalised and structured data-driven approach to health and healthy eating.

2. Work Performance and Eating Habits

Healthy eating habits significantly influence an individual's work performance.

A study published in the Journal of Occupational Health Psychology found that employees who maintain a nutritious diet experience  increased job satisfaction , reduced stress , and improved  productivity .

Healthy eating in the office can foster a positive work environment.

For instance, a study in the  NIH found that employees who have access to healthy snacks and balanced meals at work report higher levels of engagement and overall job performance.

All in all, promoting healthy eating habits in the workplace can be a critical factor in enhancing work performance.

3. Nutrition Misinterpretation and Its Consequences

The tangible effects of nutrition on work performance can be significant, but it's crucial to avoid overly simplistic interpretations of this relationship.

For instance, the Global Wellness Institute's 'Nutrition For Healthspan' initiative warns against the potential harm of misinterpreting or misusing nutritional information.

They argue that nutrition is not a one-size-fits-all solution and that individual dietary needs and preferences must be taken into account.

Similarly, companies like Google have improved in terms of promoting certain diets or nutritional approaches considering the diverse needs of their employees by prioritising healthy foods over unhealthy ones in a smart way.

Google's approach is unique because it doesn't mandate specific eating habits or eliminate unhealthy options.

Fizzy drinks, sweet snacks, desserts, and other less healthy items remain available.

Instead, Google has focused on rearranging the "foodscape" in cafeteria layouts and snack rooms, making vegetable dishes and healthier options more appealing and plentiful. This strategy includes placing salad bars at the front, expanding vegetable options, providing smaller plates, and reducing portions of desserts and meats.

The impact of this programme is notable.

In Google's New York office, which serves over 10,000 people daily , thousands of salads are now served for breakfast—an option introduced just a few years ago and one that is not typically part of the American breakfast routine.

Water consumption has surged, as has seafood consumption. By moving unhealthy snacks farther from the coffee machines, Google reduced snacking by 23% for men and 17% for women .

This innovative approach to workplace dining not only enhances employee well-being but also reflects Google's commitment to fostering a healthier, more productive work environment.

4. A Balanced Approach to Nutrition and Work Performance

Nutrition does impact work performance, but it's a complex relationship that can't be reduced to simple cause-and-effect.

The metrics used to measure this connection, such as productivity and cognitive function, offer valuable insights but have their limitations.

They may not fully capture the intricacies of individual responses to nutritional changes or the broader social and personal factors that influence work performance.

Therefore, while acknowledging the importance of nutrition, we must caution against overdependence on nutritional changes alone for performance improvement.

A balanced view is essential, considering individual circumstances, needs, and holistic assessments.

For a more comprehensive approach to workplace wellness, additional measures should be considered such as a more detailed assessment of the employee needs and wants.

5. Can Diabetes Be Cured?

While there is currently no definitive cure for diabetes, various treatments can help manage the disease and even put it into remission.

Type 2 diabetes, often linked to obesity, can sometimes be reversed  through significant lifestyle changes, such as adopting a low-calorie diet, increasing physical activity, and losing weight.

A small number of studies have shown that bariatric surgery and therapeutic fasting can also help reverse type 2 diabetes .

However, these treatments are not widespread and require further research.

On the other hand, type 1 diabetes, an autoimmune disease, cannot be cured. Some promising treatments, such as islet cell transplantation can improve the quality of life for type 1 diabetics, but these treatments are still in the experimental stages.

It's crucial to consult with healthcare professionals before making any significant changes to your treatment plan.

6. The Role of Sugar and Alcohol in Diabetes

Contrary to popular belief, consuming sugar  does not directly cause type 2 diabetes.

However, a diet high in added sugars can contribute to obesity, heart disease and stroke , a significant risk factor for the disease.

Drinks with high sugar content, like sodas, are associated with an increased risk of diabetes.

While sugar can cause spikes in blood sugar levels, it's only part of the overall picture.

As for alcohol, it can affect blood sugar levels  in people with diabetes. Alcohol can cause both low and high blood sugar, depending on the amount consumed and the type of diabetes medication being used.

It's important for individuals with diabetes to monitor their blood glucose levels closely when consuming alcohol.

7. Does Exercise Lower Blood Sugar?

Yes, exercise can indeed lower blood sugar levels .

Physical activity increases insulin sensitivity, which means your muscle cells can use any available insulin more effectively to absorb glucose.

This process helps lower blood glucose levels during and after activity.

Regular physical activity can also reduce your A1C , a measure of your average blood glucose levels over the past 2-3 months.

Monitoring your blood glucose levels before and after exercise can help you understand how your body responds to different activities and prevent your blood glucose from going too high or too low.
