Nutritional imbalance is when nutrients are not present in the human body in appropriate amounts
Nutritional imbalance can occur due to overconsumption or underconsumption of specific nutrients.
Define overconsumption.
Overconsumption is when foods or nutrients are consumed in excessive amounts
This can lead to various health issues.
Define underconsumption.
Underconsumption is when foods or nutrients are consumed in insufficient amounts
This can lead to deficiencies and health problems.
What are the short-term consequences of lack of water?
Dehydration, which may lead to headaches and reduces the efficient functioning of the body
Dehydration negatively impacts physical health and wellbeing.
What is the effect of excessive sodium consumption?
It can lead to high blood pressure, negatively impacting the function of the heart and blood vessels
This reduces physical health and wellbeing.
What are the consequences of lack of fibre?
Constipation, which interrupts normal digestive functioning
This reduces physical health and wellbeing.
What are the short-term effects of lack of iron?
Fatigue, which leads to reduced energy levels and tiredness
A lack of iron reduces physical health and wellbeing.
What is a consequence of excessive saturated and trans fat?
High blood cholesterol, which can narrow the arteries and reduce heart function
This contributes to reduced physical health and wellbeing.
What long-term health issue can result from overconsumption of fats, carbohydrates, and sodium?
Cardiovascular disease, due to increased blood cholesterol levels
This increases morbidity from cardiovascular disease.
What is the long-term consequence of underconsumption of calcium?
Osteoporosis, due to reduced density and strength of bones
This increases the risk of developing osteoporosis.
What can excessive protein consumption lead to?
Overweight and obesity, as protein is converted to fat and stored as tissue
This negatively impacts bodily functioning and physical health.
What health issue is linked to overconsumption of carbohydrates (sugar)?
Dental caries, which can cause pain and inflammation in the mouth
This reduces physical health and wellbeing.
What can underconsumption of Vitamin C and fibre increase the risk of?
Cancer, due to increased free radicals and potential for cell mutations
Lack of fibre can also contribute to colorectal cancer.
What are the consequences of underconsumption of iron and folate?
Anaemia, which leads to insufficient red blood cells and inadequate oxygen delivery
