NUTRITIONAL NEEDS OF PARTICULAR HEALTH CONDITIONS

CONDITION NUTRITIONAL PROBLEM REDUCED INTAKE NEEDED INCREASED INTAKE NEEDED
Alcohol abuse

- Ethanol (alcohol) toxicity

- Energy(kilocalorie or kilojoule) excess

- Vitamin deficiencies:
  • Thiamin
  • Folacin
  • Niacin
- Element (mineral) deficiencies:
  • Zinc
  • Magnesium
- All alcoholic beverages - Nutrient-dense foods (foods with a high concentration of essential nutrients)
Diabetes

- Weight control

- Blood glucose (sugar) should be kept between 3.5 and 9 millimoles per litre (mmol/l).

- Blood fats (cholesterol and triglycerides) should be normal (cholesterol less than 6.5mmol/l, triglycerides less than 1.8 mmol/l).

- Energy-dense foods (foods high in calories)

- Foods with little dietary fibre

- Animal (saturated) fat

- Large quantities of food at any one time (food intake should be spread out)

- Wholegrain cereals

- Vegetables (especially legumes)

- Fruits

Coronary heart disease, where blood fats are high (hyperlipidaemia)

Also for other atheroscleroticFind out more about this term vascular diseases (hardening of the arteries)

- High blood cholesterol

- High blood triglycerides

- Low blood level of high-density lipoprotein (HDL)

- Sticky platelets (small blood cells contributing to clots and thromboses)

- Fatty foods, especially of animal origin

- Cholesterol-rich foods

- Foods with little dietary fibre

- Wholegrain cereals

- Vegetables

- Fruits

- Fish

Hypertension (high blood pressure) - Blood pressure is raised by:
  • High sodium
  • Low potassium
  • High ethanol
  • High body weight
  • Low polyunsaturated to saturated fat ratio
  • Low dietary-fibre-rich foods
- Energy-dense foods

- Alcohol

- Sodium-rich foods

- Animal fats

- Potassium-containing foods

- Dietary-fibre-rich foods

Osteoarthritis (degeneration of weight-bearing joints such as hips and knees) - Overweight - Energy-dense foods (especially foods with high fat, alcohol-containing, and with low dietary fibre) .
Gout - High uric acid level in blood and/or urine - Alcoholic beverages

- Energy-dense foods

- Purine-rich foods (foods with much nuclei acid, such as organ meats and yeast)

.
Coeliac disease - Sensitivity of gut lining to gluten, resulting in poor absorptionFind out more about this term of nutrients - Wheat flour and products containing gluten, e.g. barley, rye, buckwheat, malt, oats - Maize, soya, rice and potato can be used safely
Cystic fibrosis (resulting in growth retardation and vitamin deficiencies) - Inadequate digestive capacity because of reduced enzyme production by the pancreas

- Altered sweat gland secretion

. - Energy-dense foods according to individual tolerance

- Nutrient-dense foods (some foods are both nutrient and energy dense)

- Adequate salt intake
