Having too much oxygen in your body creates free radicals.

身体里过多的氧气会产自由基。

Also, remember to have lots of Vitamin C as it is a powerhouse of antioxidants and can combat free radicals.

此外，要记住摄入量的维素C，因为它是抗氧化剂的强力量，可以对抗自由基。

Meaning, when exposed to oxygen or heat, they can form toxic byproducts and free radicals.

意思是，当遇到氧或被加热时，多元不饱和脂肪酸极易产有副产物及自由基。

Free radicals are highly reactive chemical entities that can damage cells.

Antioxidants in fruits and vegetables strengthen the brain to fight off free radicals that destroy brain cells, enabling your brain to work well for a longer period of time.

水果和蔬菜中的抗氧化物质，强化脑对抗破坏脑细胞的自由基，让脑部得以长时间运作良好。

Additionally, citrus peels are rich in vitamin C and various bioflavonoids, which have anti-inflammatory and immune-boosting properties. Citrus peels also possess antioxidants that help fight free radicals, reduce the risk of chronic diseases, and boost skin health.

此外，富含维素C和各种物类黄酮，具有抗炎和增强免疫力的特性。还含有抗氧化剂，有助于对抗自由基，降低患慢性疾病的风险，并改善肤健康。

Unregulated inflammation means lots of proteases, platelet activating factor, and free radicals floating around the gastrointestinal tissue which ultimately causes destruction of healthy tissue.

不受控的炎症反应意味着量的蛋白酶、血小板活化因子和自由基在胃肠道组织中流动，最终导致正常组织的破坏。

If oxygen steals electrons from molecules in our bodies, it creates unstable molecules called free radicals that can damage cells.

如果氧气从我们体内的分子中窃取电子，它会产不稳定的分子，称为自由基，会损害细胞。

Electrons love travelling in pairs and are most stable that way, but free radicals have unpaired electrons.

电子喜欢成对活动，并且它在这种模式下最稳定，但是自由基会破坏成对的电子。

Free radicals which can oxidize cholesterol and thus lead to heart disease.

自由基能氧化胆固醇，从而导致心脏病。

It can react with compounds in our bodies and create those free radicals.

它可以与我们体内的化合物反应，产自由基。

Because PAHs form with the help of free radicals, and antioxidants could slow down that process.

因为多环芳烃需要借助自由基成，而抗氧化物质能减缓这一过程。

It is unlike you to introduce such a free radical into an otherwise highly functional relationship.

让这样一个不稳定因素加入一个高功能性的关系中不像你会做的事。

The cytokines attract Inflammatory cells like macrophages which start releasing even more inflammatory substances like proteases, platelet activating factor, and free radicals, all which contribute to inflammation.

这些细胞因子可以募集更多的炎症细胞如巨噬细胞；这些巨噬细胞进而释放更多的炎症介质，如蛋白酶、血小板活化因子和自由基，它们都可以进一步促进炎症反应。

And even if antioxidants aren't overwhelmed, some free radicals still slip through, slowly damaging our cells year after year.

即使抗氧化剂没有被淹没，一些自由基仍然会溜走，年复一年地慢慢破坏我们的细胞。

Antioxidants are molecules in lots of fruits and vegetables that can easily give up electrons to free radicals and keep them from reacting with cells and doing damage.

抗氧化剂是许多水果和蔬菜中的分子，很容易将电子释放给自由基，防止它们与细胞反应并造成损害。

Beer, for example, has a light-sensitive chemical called " isohumulone" inside of it that breaks down into free radicals when struck by ultraviolet light.

比如，啤酒里面含有一种叫做“异葎草酮”的化学成分，它对光很敏感，当紫外线照射时，它会被分解成自由基。

So when you heat vegetable oils, free radicals as well as small lipid fragments called aldehydes can form.

所以，当被加热时，菜油会产自由基和一种名叫乙醛的脂质碎片。

Because of their instability, free radicals are on the hunt for more electrons and will take them from things like DNA, proteins, and fats—reacting with those molecules and damaging them in the process.

由于这些自由基的不稳定性，它们还会继续寻找更多电子，将它们和 DNA、蛋白质和脂肪一类的物质分离，与分子反应，逐步破坏分子。

And when it does this, the free radical changes the chemical structure of those molecules, sometimes damaging them.

当它这样做时，自由基会改变这些分子的化学结构，有时会破坏它们。
