Diet

Diet - providing or obtaining the food necessary for health and growth, choice of nutrition.

  • Undernutrition

    Undernutrition is a form of malnutrition. (Malnutrition also includes overnutrition).

    Undernutrition can result from:

    • inadequate ingestion of nutrients,
    • malabsorption,
    • impaired metabolism,
    • loss of nutrients due to diarrhea,
    • increased nutritional requirements.

    Undernutrition progresses in stages: it may develop slowly when it is due to anorexia or very rapidly. First, nutrient levels in blood and tissues change, followed by intracellular changes in biochemical functions and structure. Ultimately, symptoms and signs appear. Diagnosis is by history, physical examination, body composition analysis, and sometimes laboratory tests. 

    Undernutrition from micronutrient deficiencies, or "hidden hunger", affects over 2 billion people globally and can lead to reduced growth and cognitive development, birth defects, blindness, and overall poor health. Vitamin A deficiencyiron deficiency anaemia and iodine deficiency disorders are among the most common forms of micronutrient malnutrition. 

  • Overnutrition

    Overnutrition, a type of malnutrition, is emerging with rates of obesity and related chronic diseases associated with urbanisation, aging populations, technological development and globalisation of food supplies and industry. Billions of dollars are spent annually by the food industry to promote the consumption of highly refined, high-calorie foods with little or no nutritional value. 

    At least 35 million overweight children are living in developing countries and 8 million in developed countries. Children are increasingly exposed to high-fat, high-sugar, high-salt, energy-dense, micronutrient-poor foods which tend to be cheaper than healthy foods. General imbalance in energy intake compared to physical activity levels is driving the obesity epidemic. In industrialised countries, child obesity risk is associated with lower household income, women with less education, and single parent households.

    Obesity is increasingly prevalent among adolescent girls and women, as access to a greater quantity of inexpensive, tasty, and convenient foods increases. 

    Taxation on high-calorie, low-nutrition foods can play a significant role in reducing the consumption of such products. Population-wide weight-control campaigns that raise awareness among medical staff, policy-makers and the public at large can also help to reduce obesity. Particularly important is the promotion of health literacy. Additional measures include restrictions on the marketing of unhealthy foods and sugary drinks to children, and controls on the use of misleading health and nutrition claims; mandatory front-of-pack food labelling helps consumers to identify healthier options. 

  • Child's Right to Adequate Nutrition

    A child’s right to adequate and appropriate nutrition is stipulated under Article 6 and 24 of the Convention on the Right’s of the Child. 

    In 2010, an estimated 171 million children (167 million of whom live in developing countries) were stunted. Children who are stunted are at a greater risk of having difficulty learning, playing, engaging in normal childhood activities and being productive members of society later in life. Undernourished children are also more susceptible to frequent and repeated disease and illness due to a weakened immune response, as well as at a greater risk of becoming overweight or obese later in life.

    A child’s nutritional future begins with the mother’s nutritional status in adolescence and during pregnancy.

  • Paleo Diet Based on Fruits and Seeds

    About paleo diet from an expert Christina Warinner: paleo people did not eat much meat, they did eat seeds, grains and legumes, of cause fresh fruit. Their diets were regionally and seasonably variable.

  • Nori and Chlorella for B12

    A nutritional analysis for the dietary food intake and serum vitamin B12 (cobalamin) level of a group of 6 vegan children aged 7 to 14 who had been living on a vegan diet for 4 to 10 years suggests that consumption of nori may keep vegans from suffering vitamin B12 deficiency.

    Rauma et al. also reported that vegans consuming nori and/or chlorella had a serum vitamin B12 concentration twice as high as those not consuming these algae.

  • Vegetarian Diets and Health

    Vegetarian diets do not contain meat, poultry or fish, vegan diets further exclude dairy products and eggs. Vegetarian and vegan diets can vary widely.

    In general, vegetarian diets provide relatively large amounts of cereals, pulses, nuts, fruits and vegetables.

    In terms of nutrients, vegetarian diets are usually

    • rich in carbohydrates, n-6 fatty acids, dietary fibre, carotenoids, folic acid, vitamin C, vitamin E and Mg,
    • relatively low in protein, saturated fat, long-chain n-3 fatty acids, retinol, vitamin B12, zinc (Zn),
    • vegans may have particularly low intakes of vitamin B12 and low intakes of Ca.

    On average, vegetarians and vegans have a relatively low BMI and a low plasma cholesterol concentration, but higher plasma homocysteine concentrations than in non-vegetarians. Overall, the data suggest that the health of Western vegetarians is good and similar to that of comparable non-vegetarians.

  • Vegetarian Diets and Heart Disease

    In comparison with regular meat eaters, mortality from ischemic heart disease was

    • 20% lower in occasional meat eaters,
    • 34% lower in people who ate fish but not meat,
    • 34% lower in lacto-ovo-vegetarians,
    • 26% lower in vegans.

    There were no significant differences between vegetarians and non-vegetarians in mortality from the other causes of death examined.

  • Fruits and Vegetables for Healthy Bones

    The positive link between bone health and fruit and vegetable consumption has been attributed to the lower renal acid load of a diet high in alkaline-forming fruits and vegetables.

    Other important dietary determinants of bone health include micronutrients and bioactives found in fruits and vegetables.

  • Vegan Diet Protects from Cancer

    Vegan diets showed statistically significant protection for overall cancer in both genders combined, and for female-specific cancers.

  • Whole Fruits for Satiety

    For satiety choose whole fruit over smoothies and juices.

    Solid fruits affect feeling of fullness more than pureed fruit or juice. Adding naturally occurring levels of fiber to juice do not enhance satiety.

To be is to be perceived.

Water

Water is an essential nutrient - it is required in amounts that exceed the body's ability to produce it. All biochemical reactions occur in water. It fills the spaces in and between cells and helps form structures of large molecules such as protein and glycogen. 

Most foods contain water. The body can usually get 20% of its total water requirements from solid foods alone. The human body can last weeks without food, but only days without water. 

The digestion process also produces water as a byproduct and can provide around 10 per cent of the body’s water requirements.  

Water is a transparent and nearly colorless chemical substance. Its chemical formula is H2O, meaning that its molecule contains one oxygen and two hydrogen atoms

Water covers 71% of the Earth's surface. It is vital for all known forms of life. On Earth, 97% of the planet's crust water is found in seas and oceans, 1.7% in groundwater, 1.7% in glaciers and the ice caps. Only 2.5% of this water is freshwater, and 98.8% of that water is in ice (excepting ice in clouds) and groundwater. Less than 0.3% of all freshwater is in rivers, lakes.

Safe drinking water is essential to humans and other lifeforms even though it provides no calories or organic nutrients. ~One billion people still lack access to safe water. It was estimated that by 2025 more than half of the world population will be facing water-based vulnerability, and by 2030 water demand in some developing regions of the world will exceed supply by 50%.

Approximately 70% of the freshwater used by humans goes to agriculture.
