Answer:
Consuming animal fats from larger mammals, such as cows, pigs, and sheep, may not be considered healthy in excess due to their high levels of saturated fat, which can increase cholesterol levels and the risk of heart disease. Moreover, larger mammals tend to accumulate a higher concentration of toxins such as mercury, PCBs, and dioxins in their tissues, which can pose health risks when consumed. Therefore, it is recommended to consume animal fats from leaner options or in moderate quantities.
