Another Reason to love oats!!: Antioxidant Series


Oats are wonderful for so many reasons: they are a whole grain, low fat, a good source of fiber, full of nutrients, and are a delicious and filling.

Considering the amazingness of oats on a whole, it isn't surprising that they are also a good source of antioxidants! Oats contain an antioxidant called avenanthramides (avns for short).

Avns are part of a group of antioxidants called phytoalexins. They are important to oats as plants because they help make them resistant to diseases. In humans, avns act as antioxidants to help protect our cells from oxidation. Oats and avns are associated with decreased risk of cardiovascular disease (related to prevention of over fed macrophages!) Avns, even isolated from oats, help to reduce cytokines (inflammatory markers) in the body, and help reduce cholesterol.

As with all antioxidants, more research is needed, but overall, oats have everything going for them… but just in case you needed one more reason to eat some- there you have it: avns :)

Coffee's Health Benefits: Antioxidant Series


Coffee, is a great love of mine. Its warm, tasty, wakes you up, and is great to dip things in.


Other than all of those benefits, didja know coffee also contains molecules that are antioxidants?? (See my last post for my attempt at explaining antioxidants.)

Coffee contains these wonderful compounds called polyphenols. And in fact- coffee consumption actually provides more than 60% of antioxidants consumed in America.


Epidemiological studies have shown that coffee consumption correlated with less ‘oxidative stress’, aka, less cells with their identity stolen, and less inflammation.


Sometimes coffee gets a bad wrap, in regards to it staining teeth, or its caffeine being bad if you have high blood pressure, but overall it’s hard to really analyze coffee. Many studies looking at specifically at coffee consumption in humans is difficult to translate, because often coffee drinkers also have other negative lifestyle factors such as smoking, or not consuming many fruits and vegetables.


Looking at coffee in animal studies, in vitro (just looking at the cellular interactions), and some human studies have shown positive results for coffee as an antioxidant. Coffee has been associated with decreased risk of heart disease, Alzheimer’s disease, liver disease and type II diabetes. It does this through preventing oxidative reactions, or stopping free radical reactions.


Currently there is no absolute proof that coffee is beneficial, however, it is known that the antioxidant polyphenol compound does exist in the beverage. More well controlled human studies are needed.


But in my opinion, if you enjoy your daily cup of java, go ahead and enjoy :) your body just might thank you later.
