The optimal healthy level of ferritin for humans is not definitively known, but some recommend lower levels due to potential issues with excess iron.

◐Partially SupportedFeeding animals high linoleic acid diets could lead to weight gain in humans.

◐Partially SupportedElevated ferritin, iron saturation, and transferrin saturation may indicate problematic iron overload.

◐Partially SupportedChicken fed corn and soy can accumulate linoleic acid, making grass-fed beef a higher quality meat choice.

◐Partially SupportedPaul Saladino eats liver and heart daily, and ground beef daily, believing these are the most nutrient-dense and least toxic sources of animal protein.

◐Partially SupportedPaul Saladino's ferritin level is 252, down from 332, with a goal under 150, possibly under 100.

◐Partially SupportedEating chicken, fish, or pork is better than eating plant-based burgers.

◐Partially SupportedPaul Saladino's total iron binding capacity is up, iron is down, and iron saturation is down from 42% to 31%.

◐Partially SupportedIndividuals without hemochromatosis genes may benefit from monitoring iron levels, particularly concerning hormones and overall health.

◐Partially SupportedDaily consumption of red meat and organs, combined with good iron absorption, can lead to high iron intake.

◐Partially SupportedIncreasing dietary intake of boron-rich foods may decrease Sex Hormone Binding Globulin (SHBG).
