Age-related anemia may also be linked to increased levels of hepcidin, a hormone that reduces iron absorption in the intestine, leading to low iron levels. [175] The recommended daily intake of iron for both men and women is 8 mg, with an upper limit of 45 mg/day.
Absorption of dietary iron in iron salt form (as in most supplements) varies somewhat according to the body's need for iron, and is usually between 10% and 20% of iron intake. Absorption of iron from animal products, and some plant products, is in the form of heme iron, and is more efficient, allowing absorption of from 15% to 35% of intake.

The four organogenic elements, namely carbon , hydrogen , oxygen , and nitrogen ( CHON ), that comprise roughly 96% of the human body by weight, [ 7 ] are ...
The recommended daily amount of drinking water for humans varies. [1] It depends on activity, age, health, and environment.In the United States, the Adequate Intake for total water, based on median intakes, is 4.0 litres (141 imp fl oz; 135 US fl oz) per day for males older than 18, and 3.0 litres (106 imp fl oz; 101 US fl oz) per day for females over 18; it assumes about 80% from drink and 20 ...
In the United States and Canada, recommended dietary intake levels of essential nutrients are based on the minimum level that "will maintain a defined level of nutriture in an individual", a definition somewhat different from that used by the World Health Organization and Food and Agriculture Organization of a "basal requirement to indicate the ...
A new observational study involving nearly 122,000 adults suggests that a flavonoid-rich diet may significantly lower the risk of dementia, especially for those with genetic predispositions or ...
