You can eat, but can not eat more.

Harm of lard residue:

1, lard residue contains a large amount of animal fat, its fat belongs to the saturated fatty acids, that is, hard fat, eat less no harm, eat more harmful to the human body, because it not only causes obesity, but also make cholesterol rise, leading to atherosclerosis, hypertension and cardiovascular disease. Therefore, generally healthy people can eat a small amount, but more obese people, the elderly, or patients with cardiovascular disease should not eat.

2, all carbon-containing organic matter (oil residue is a higher carbon content of the matter) decomposition of heat, if not fully combustible (oxidation), will produce a carcinogenic substances called "benzopyrene". Organic substances by heat decomposition, cyclization, polymerization and the formation of 3,4 benzo(a)pyrene. The content of 3,4 benzo(a)pyrene in the oil residue is very high, and the longer the frying time, the higher the content.

Directly in the bottom of the pan burnt rice coke, also contains 3, 4 benzene quake pyrene substances. 3, 4 benzene quake pyrene is polycyclic aromatic hydrocarbons (PAHs), a carcinogenic substance, which is an organic compound containing 4 or more benzene rings. Polycyclic aromatic hydrocarbons (PAHs) are the most widely distributed and numerous environmental carcinogens, accounting for more than 1/3 of the total number of more than 1,000 carcinogens. Therefore, for the lard residue of such food, do not eat, otherwise, is bound to increase the intake of 3,4 benzene quake pyrene, that is, to increase the incidence of esophageal cancer, stomach cancer.

3, lard boil lard time is long, the oil temperature is very high, when the oil temperature is up to 200 ℃ above, will produce a large number of peroxides and other carcinogens; boiling charred oil residue will also produce tar, dimethyl nitrosamine and other carcinogens.

4, long-term consumption of oil residue, can induce stomach cancer, because the oil residue in the stomach is not easy to digest, a long time in the stomach to stay, prompting the gastric juice (gastric acid) secreted a lot of gastric mucous membrane caused by a long period of time stimulation, over time, leading to gastric mucous membrane erosion ulcers, resistance to weakening, coupled with the stimulation of carcinogens on the mucous membranes of the digestive tract, then increase the incidence of esophageal cancer, gastric cancer.
