1. Chocolate with white or grayish film is fine to eat

结了纯白色或灰色膜的巧克力也能吃

While white or grayish film formed on the surface of chocolate might not look very appetizing, turns out its perfectly fine to eat. The process occurs when cocoa butter fats separate from the cocoa.

巧克力表面结了一层白色或灰色膜大约看上来让人没有食欲，但理论上纯粹可以吃。这是可可脂和可可分离的下场。

2. Double-dipping can spread bacteria and viruses

二次蘸酱会传布细菌和病毒

Sadly, double-dipping is not the greatest idea, since it can spread bacteria and viruses, even when a person isnt visibly sick or unwell. Therefore, its always best to put dip on your own plate and enjoy it without spreading germs to other people.

可悲的是，二次蘸酱不是个好主意，因为它会传布细菌与病毒，即使蘸酱的人没有患病或不恬逸的迹象。因而，最亏得自己的盘子里蘸酱享受，不要把细菌传给别的人。

3. The 5-second rule is a myth

“5秒轨则”不是真的

To test out peoples favorite "rule," Dr. Ronald Carter from Queen Mary, University of London did an experiment. He dropped pizza, apple, and toast onto different surfaces and it revealed that they were all covered in germs. As it turned out, the "5-second rule" isnt true—bacteria can attach to food as soon as it touches the floor.

为了测试人们最love的这条“轨则”，伦敦大学玛丽皇后学院的罗纳尔德·卡特博士做了一个履行。他将披萨、苹果和吐司残落到差距的表面，究竟创造它们全都被细菌掩饰笼罩。事实证明，“5秒规律”不是真的，食物一遇到空中，细菌就会附着在食物上。

4. Refrigerated leftovers must be tossed out in 3 to 4 days

冰箱里的剩菜必需在三四天内丢弃

We all know that some types of bacteria can cause illness. However, as it appears, the types of bacteria that do dont affect the smell, taste, or appearance of food. This is why its crucial to either freeze or throw out refrigerated leftovers within 3 to 4 days.

我们都知道，某些类型的细菌会致病。然而，致病的细菌宛若并不会影响食物的气味、口感和外表。这便是为什么冰箱内的剩菜未必要冷冻或在三四天后丢掉。

5. Titanium dioxide thats found in icing has been linked to inflammatory bowel diseases

糖霜里含的二氧化钛会招致炎症性肠道疾病

Titanium dioxide—an additive thats used to make white appear even whiter—can be found in a variety of foods, like coffee creamer, icing, powdered sugar, and ranch dressing. However, for the exact same reason, it is used in making sunscreens, laundry detergents, and paint. FDA considers the additive safe; however, there was research conducted that linked it to inflammatory bowel diseases. In addition to this, as of 2020, France has banned titanium dioxide in food.

让纯白色物体显得更明的二氧化钛增进剂在多种食物中都能找到，比如咖啡奶精、糖霜、糖粉与牧场沙拉酱。出于同样的起因，这类增进剂也用于产防晒霜、洗衣粉和颜料。美国食物和药物筹划局以为这种增多剂是保险的，但是钻研缔造二氧化钛也许会导致炎症性肠道疾病。2020年法国已经制止在食物中增长二腐蚀钛。
