The phrase "high dietary intake" refers to a person's consumption of food or nutrients that is above average, excessive or abnormally high. This can mean consuming more calories than needed for maintaining a healthy weight, taking in an excess amount of certain vitamins or minerals, or eating too much of specific food groups that may lead to unhealthy imbalances in one's diet. A high dietary intake can have both positive and negative effects on a person's health depending on the type and quality of food consumed.
