Avocado inside black can not eat.

As long as the fruit is moldy and rotten, all kinds of microorganisms, especially all kinds of fungi will continue to accelerate the propagation in the rotten fruit and produce a large number of toxic substances in the propagation process. These toxic substances and constantly from the decay part, through the fruit juice to the undecayed part of the infiltration, diffusion, resulting in the undecayed part of the same contains microbial metabolites.

People eating rotten fruit in the fungal toxins, may occur dizziness, headache, nausea, vomiting, abdominal distension, etc., the serious will also occur in a stroke, coma, life-threatening. One of the most toxic substances that pose the greatest threat to human health is the toxins of the Penicillium sporogenes fungus. Eaten in addition to the nerve, respiratory, urinary and other systems to cause harm, there is a strong carcinogenic effect. In addition, the fruit after rotting its nitrate, will become toxic nitrite.

Special attention should be paid to the moldy parts of the removal and then eat may not be safe, because the mold produced by the exhibition of penicillin can spread to other parts of the fruit. A survey by the Chinese Academy of Preventive Medical Sciences found that moldy apples on the normal-looking parts of the exhibition of penicillin content of 10-50% of the moldy parts. Normal parts of the apple may contain as much as 3 milligrams of penicillin per kilogram. So it seems safer to send all the moldy fruit to the trash.

So, in order to be healthy, eat fruits to choose the skin color glossy, tender flesh, aroma, fresh fruit. If slightly small spots or a small amount of insect moths, the knife should be dug to the rot and insect moths and its surrounding more than 1 cm in the good part of the fruit; such as moldy rot or insect moth area of 1/3 of the fruit or more, should be decisively discarded to prevent future problems.

Bad fruit, its cells because of the damage caused by many of the nutrients have been outflow. So even if it hasn't been eaten by bacteria, it has no nutritional value, so there's no need for us to eat it at this point.

Expanded:

Generally sugary, water-rich foods are most susceptible to mold, as long as a mold, about 2 to 3 days to see colonies, after a week of bacterial spores began to spread, so the fruit placed together, as long as the rotten one, the other fruits will soon be affected by the wave of the reason is here.

Therefore, I would like to remind everyone that it is best to eat the fruits as soon as possible and not to keep them for too long. If the family population is small, do not be greedy for cheap, once to buy a large box, so it is easy to eat before the end of the rot, it is recommended to a small amount, more types of fruit as the principle of purchase, more able to take in a variety of nutrients at the same time, for example, once to buy 3-4 bananas plus 3 apples or guava, just to supply the whole family for one to two days of the portion, is more appropriate.
