HEALTHY EATING:
Simplifying mixed messages …….

Introduction
nutritional ‘features’ have become a key feature in the popular press
focus can be on both health or performance
whilst optimal advice may need to be specific to the needs of the individual .....
general dietary principles are similar for all
some examples …..?
![Page 5: Newcastle University Prof. Chris Seal & Dr. Amelia Lake Healthy Eating at Work (Research Project)](https://reader036.fdocuments.in/reader036/viewer/2022062409/56649c9e5503460f9495ed49/html5/thumbnails/5.jpg)
So what is the problem?
The basic principles of healthy eating are clearly ‘out there’ …..
The sad truth is that ‘we’ are;
inherently lazy and easily ‘put off’
creatures of habit
not well designed for ‘modern convenience’
reluctant to change behaviours

Problems: Mixed Messages?

Problems: Missed Messages?

Getting it right ….
The key message is to strike a balance between the amount of food consumed and the amount of energy expended.
What are the implications if this balance is allowed to slip?
![Page 9: Newcastle University Prof. Chris Seal & Dr. Amelia Lake Healthy Eating at Work (Research Project)](https://reader036.fdocuments.in/reader036/viewer/2022062409/56649c9e5503460f9495ed49/html5/thumbnails/9.jpg)
Take a look in the Mirror!
![Page 10: Newcastle University Prof. Chris Seal & Dr. Amelia Lake Healthy Eating at Work (Research Project)](https://reader036.fdocuments.in/reader036/viewer/2022062409/56649c9e5503460f9495ed49/html5/thumbnails/10.jpg)
How can we manage the balance?
‘Typical’ Energy Requirements based on ….
Females 2000 kcal
Males 2500 kcal
This energy is ultimately derived from the foods that we eat …. It is a real issue that many people have little or no idea of exactly how much food they should be eating
![Page 11: Newcastle University Prof. Chris Seal & Dr. Amelia Lake Healthy Eating at Work (Research Project)](https://reader036.fdocuments.in/reader036/viewer/2022062409/56649c9e5503460f9495ed49/html5/thumbnails/11.jpg)
What foodstuffs should our energy come from?
Protein
CHO (starch)
CHO (sugar)
Fat
< 30%
12-15%10 %
> 45%
% of total energy intake

Activity to try out at home!
Reading Food Labels …
![Page 14: Newcastle University Prof. Chris Seal & Dr. Amelia Lake Healthy Eating at Work (Research Project)](https://reader036.fdocuments.in/reader036/viewer/2022062409/56649c9e5503460f9495ed49/html5/thumbnails/14.jpg)
Spotting high fat foodstuffs …
How do you know when a foodstuff is relatively high in fat?
Divide the energy (kcal) in 100g of food by 25
note this value
Amount of fat in 100g of food should be less than this value ….. Example ….
![Page 15: Newcastle University Prof. Chris Seal & Dr. Amelia Lake Healthy Eating at Work (Research Project)](https://reader036.fdocuments.in/reader036/viewer/2022062409/56649c9e5503460f9495ed49/html5/thumbnails/15.jpg)

Practical advice to help make positive changes in behaviour.
Have you considered …..
![Page 18: Newcastle University Prof. Chris Seal & Dr. Amelia Lake Healthy Eating at Work (Research Project)](https://reader036.fdocuments.in/reader036/viewer/2022062409/56649c9e5503460f9495ed49/html5/thumbnails/18.jpg)
Reduce Portion Sizes
Do you really ‘need’ all that food?
Gratuitous use of food!
Are you a ‘plate finisher’?
Is it really necessary?
![Page 19: Newcastle University Prof. Chris Seal & Dr. Amelia Lake Healthy Eating at Work (Research Project)](https://reader036.fdocuments.in/reader036/viewer/2022062409/56649c9e5503460f9495ed49/html5/thumbnails/19.jpg)
Substitute ‘lower’ fat foodstuffs
What do you typically put on … say a baked potato?
How about cottage cheese, tuna, baked beans etc …
What type of ‘spread’ do you use
Why not use ‘low fat’ alternatives?
Mayonnaise?!
![Page 20: Newcastle University Prof. Chris Seal & Dr. Amelia Lake Healthy Eating at Work (Research Project)](https://reader036.fdocuments.in/reader036/viewer/2022062409/56649c9e5503460f9495ed49/html5/thumbnails/20.jpg)
And finally …. alcohol intake!
most people aware of effects of chronic abuse ..... liver and nervous disorders
great ignorance of ‘other’ effects
26% believed alcohol has zero calorific value
alcohol is relatively ‘energy dense’
bottle of wine ~ 600 kcal
pint of beer ~ 180 kcal
![Page 21: Newcastle University Prof. Chris Seal & Dr. Amelia Lake Healthy Eating at Work (Research Project)](https://reader036.fdocuments.in/reader036/viewer/2022062409/56649c9e5503460f9495ed49/html5/thumbnails/21.jpg)
Good nutritional practice
Take home messages ….
![Page 22: Newcastle University Prof. Chris Seal & Dr. Amelia Lake Healthy Eating at Work (Research Project)](https://reader036.fdocuments.in/reader036/viewer/2022062409/56649c9e5503460f9495ed49/html5/thumbnails/22.jpg)
General recommendations
Eat a wide variety of foodstuffs
increases opportunity to supply a wide range of nutrients
individual is less likely to omit a ‘critical’ nutritional component
![Page 23: Newcastle University Prof. Chris Seal & Dr. Amelia Lake Healthy Eating at Work (Research Project)](https://reader036.fdocuments.in/reader036/viewer/2022062409/56649c9e5503460f9495ed49/html5/thumbnails/23.jpg)
Eat low fat foodstuffs
saturated fats increases cholesterol and LDL ........ bad news
gastric emptying is slowed by addition of fat to a meal
gives feeling of ‘fullness’ and can prevent adequate consumption of CHO
![Page 24: Newcastle University Prof. Chris Seal & Dr. Amelia Lake Healthy Eating at Work (Research Project)](https://reader036.fdocuments.in/reader036/viewer/2022062409/56649c9e5503460f9495ed49/html5/thumbnails/24.jpg)
Eat wholemeal breads, cereals, vegetables and fruit complex CHO
help restore depleted muscle glycogen
contain fibre minerals and vitamins
exercise some caution
large quantities may be too bulky/filling ...
