Idea 2

In the context of a healthy diet, antioxidants are substances found in food items which help shield biological molecules such as DNA from this potentially destructive activity. These substances include vitamins like vitamin C and vitamin E , trace elements such as selenium and zinc , and other common plant compounds such as lycopene and flavonoids .

Idea 4

What causes oxidative stress?

Our bodies naturally produce a range of chemical products called free radicals as a consequence of typical metabolic processes. These include reactive oxygen species such as hydrogen peroxide , which is both destructive and – under some circumstances – a useful signalling molecule.

Idea 5

While our bodies have repair mechanisms that can account for these damaging changes, as we age the problems can pile up. Mutations get missed, aggregations of proteins build, and risks of diseases like cancer or even neurodegenerative conditions like Parkinson's increase.

This app is LOADED with RELEVANT, HELPFUL, AND EDUCATIONAL material. It is creatively intellectual, yet minimal enough to not overstimulate and create a learning block. I am exceptionally impressed with this app!

Giovanna Scalzone

Laetitia Berton

I have only been using it for a few days now, but I have found answers to questions I had never consciously formulated, or to problems I face everyday at work or at home. I wish I had found this earlier, highly recommended!
