An unbalanced diet can lead to both nutrient deficiencies and excesses that impact health. A vitamin A deficiency caused by not eating foods like sweet potatoes and carrots can result in night blindness and impaired skin maintenance. Consuming too many sugary foods and drinks high in calories can lead to tooth decay by promoting the growth of bacteria that damage enamel. Overall, balancing nutrition through a varied diet containing necessary vitamins, minerals, proteins and other nutrients supports overall health and well-being.

1. The impact of diet on
nutrition

2. Starter
 Aim to list 5 effects of an unbalanced diet

3. Cause and Effects
 You are going to be presented with 5 sub headings. Please use these sub heading in your work.
 For each effect you are going to be asked to describe the cause. This must relate to nutrition and
specific foods. For example: The cause of obesity is eating too much processed foods that are
high in saturated fats and sugars. Such as, crisps, chocolate, takeaways.
 For each heading you are also going to be asked to describe the effect it can have on the body.
This must relate to physical effects. For example, obesity can affect an individual by making them
gain weight, development joint and muscle pain. Also an induvial is much more likely to
experiences breathing and heart problems.

4. Long-term effects of balanced and unbalanced diets
Over-nutrition
• Coronary heart disease
• Obesity
• Type 2 diabetes
• Stroke,
• Weight gain
Choose one of the above conditions and describe the cause and the effect.
Use the example on the previous slide to guide you.

5. Under nutrition
 Specific nutrient deficiencies (You choose a specific nutrient but be aware that you are not repeating
in the next few slides)
 Low concentration span (think about foods that help concentration. If someone is not getting enough of these
foods what might happen)
 Choose one of the above and describe the cause and the effect
Long-term effects of balanced and
unbalanced diets

6. Long-term effects of balanced and unbalanced diets
Vitamin deficiency: Remember a deficiency is when someone is not eating enough of something
 Vitamin A, e.g. night blindness, impaired maintenance and repair of skin, mucus membranes, accelerated
ageing
 Vitamin B, e.g. beriberi
 Vitamin C, e.g. scurvy
 Vitamin D, e.g. rickets, bone loss-osteoporosis, low blood calcium, brittle bones, impaired tooth formation
 Vitamin E, e.g. lethargy, apathy, muscle weakness
 Vitamin K, e.g. impaired blood clotting
 Choose one of the above deficiencies and describe the cause and the effect

7. Long-term effects of balanced and unbalanced diets
Mineral deficiency: Remember a deficiency is when someone is not eating
enough of something
 Calcium (impaired bone and teeth formation)
 Iron (anaemia)
Choose one of the above conditions and describe the cause and the
effect

8. Long-term effects of balanced and unbalanced diets
Nutrient excess: What foods are high in sugar?
 Tooth decay
