The Impact of Poor Nutrition

Poor nutrition can lead to weight gain or obesity, caused by a high intake of energy-dense, nutrient-poor foods like fast food and sugary drinks.
Nutrient insufficiencies can result in conditions such as osteoporosis (too little calcium), anaemia (too little iron or B12) or scorbutus (Vitamin C deficiency).
Eating an unrestrained amount of saturated and trans fats can increase the risk of health problems, most notably heart disease and stroke.
Overconsumption of sodium, which is particularly high in processed foods, can lead to elevated blood pressure, a major risk factor for cardiovascular diseases.
Deficient fibre intake can contribute to digestive problems such as constipation and diverticular disease.

There is increasing evidence that poor diet can play a crucial role in the development of mental health issues, particularly depression and anxiety disorders.
Nutritional deficiencies can lead to impaired cognitive function, affecting concentration, memory and academic performance.
Overeating or under-eating could be signs of eating disorders such as anorexia or bulimia nervosa, which are severe medical illnesses often connected to mental stress.
Unhealthy dietary habits can lower self-esteem and body-image perception, leading to mental distress.

The impact of poor nutrition stretches beyond the individual and can have profound societal implications.
It can put a strain on healthcare systems due to increased medical costs related to diet-related diseases.
Societies can face increased disability and loss of work from chronic illness, bringing economic burdens through lost productivity.
The prevalence of diet-related health problems can widen health disparities among different socio-economic groups, as healthier food options are often more expensive.
Poor nutrition in children can hinder their growth and development, impacting their learning potential and future economic contribution.
