A health worker is interested in determining if omega-3 fish oil can help reduce cholesterol in adults. She obtains permission t
Dominik [7]

Answer:

  1. Observational study
  2. See explanation below
  3. No

Explanation:

  1. This is an observational study as the health worker did not conduct any experiment but instead, she observed and studied patients data and drew her inferences from the available data.
  2. A confounding is an external variable in an experiment that can change the effect of the dependent and independent variable. They can ruin an experiment if not accounted for and suggest false correlations, and introduce bias as it is one of the sources of bias in epidemiological studies. For example, using the study above, it is said that the cholesterol reading of the group not taking omega-3 fish oil is 18 points higher than the other; a confounding variable would be like an extra independent variable unaccounted for which could influence the outcome of the study like the age of the patients, family history, diet etc. All these extra variables can influence the cholesterol level of the patients but yet were unaccounted for and if inferences are made from the observations, the correlations could be false.
  3. Even though the 18 point difference is statistically significant, they cannot conclude that omega-3 fish oil is the cause because of the effect of confounding in experiments and the many external variables like lifestyle, diet, smoking etc. which could influence the outcome of the research that were unaccounted for

An essay about balance diet​
NikAS [45]

Answer:

A balanced diet is one that provides an adequate intake of energy and nutrients for maintenance of the body and therefore good health. A diet can easily be adequate for normal bodily functioning, yet may not be a balanced diet. An ideal human diet contains fat, protein, carbohydrates, vitamins, minerals, water and fibre all in correct proportions. These proportions vary for each individual because everyone has different metabolic rates and levels of activity.

Malnutrition results from an unbalanced diet, this can be due to an excess of some dietary components and lack of other components, not just a complete lack of food. Too much of one component can be as much harm to the body as too little. Deficiency diseases occur when there is a lack of a specific nutrient, although some diet related disorders are a result of eating in excess. An adequate diet provides sufficient energy for the performance of the body to function.

Carbohydrates, fats and proteins provide energy. Proteins are a provider of energy in an emergency, but are primarily used as building blocks for growth and repair of many body tissues. We also need much smaller amounts of other nutrients, such as vitamins and minerals. Despite the small quantities needed these are essential to provide a healthy diet.

Within the cells of our body, the nutrients ingested are converted to other compounds, which are then used for metabolism and other cellular reactions. Starch, a major carbohydrate is converted to glucose which can be then synthesised into fat for storage, proteins are synthesised from amino acids, and phospholipids are made from glycerol and fatty acids.

Carbohydrates are a rapid source of energy; they are the body's fuel. The bulk of a balanced diet should be made from carbohydrates. If eaten in an excess of the dietary requirements carbohydrates are easily stored as fats in the cells.

An average adult requires about 12,000kJ of energy a day, most of this is s...
