Participants/situation

  • The paper is a review of all identifiable studies.

Study

  • The paper is a systematic review / meta analysis of all relevant trials.
  • This means that the data from all similar trials has been grouped to form an overall outcome.

Results

  • Vegetarian athletes may be at risk for low intakes of energy, fat, vitamins B12, riboflavin, and D, calcium, iron, and zinc, which are readily available from animal proteins. Iron is of particular concern because of the low bioavailability of nonheme plant sources. Iron stores of vegetarians are generally lower than omnivores.
  • Vegetarian athletes, especially women, may be at greater risk for developing iron deficiency or anaemia.
  • Because plant proteins are less well digested than animal proteins, an increase in intake of approximately 10% protein is advised. Therefore, protein recommendations for vegetarian athletes approximate 1.3–1.8 g per kg of body weight per day

Answer

  • As per the results above
