Vitamins A and D can be toxic at high levels, meaning it can be dangerous to greatly exceed recommended daily intake. Some vitamin-fortified foods have 100 percent of the daily intake of both vitamins. Many people overestimate what counts as a serving of these foods. Many people will consume two to three times the manufacturer-defined serving size.

Some people who eat vitamin-fortified food are exceeding the recommended daily intake of vitamins A and D by eating two to three times the serving size.

This is unsupported because we aren’t given any information about the mental state or knowledge of people consuming fortified foods. We don’t know how many are aware of the excessive levels of vitamin A and D.

This is strongly supported because we are told that some people exceed more than one serving of these foods daily, and each serving can contain 100 percent of the recommended daily levels of vitamins A and D.

This is unsupported because we are not told anything about what people know or believe.

This is unsupported because people who eat vitamin fortified foods may eat less than a serving per day, which would warrant supplements. It is also possible that people should take vitamin supplements for those vitamins not included in the vitamin-fortified foods.

This is unsupported because we are not told anything about the knowledge or awareness of manufacturers regarding how consumers eat their foods.
