How does oxidative stress affect the body?

Oxidative stress can damage cells and occurs when there is an excess of free radicals.

High cholesterol triggers mitochondrial oxidative stress leading to osteoarthritis

High cholesterol might harm more than our cardiovascular systems. New research using animal models suggests that high cholesterol levels trigger mitochondrial oxidative stress on cartilage cells, causing them to die, and ultimately leading to the development of osteoarthritis.

Beware of antioxidants, warns scientific review

The lay press and thousands of nutritional products warn of oxygen radicals or oxidative stress and suggest taking so-called antioxidants to prevent or cure disease.

Can sesame-based ingredients reduce oxidative stress?

The antioxidant boosting properties of sesame, and especially sesame oil, can have a significant effect on oxidative stress, improving human health, according to a systematic review published in…

Spinal cord neurons protected against oxidative stress by green tea polyphenols

Green tea polyphenols are strong antioxidants and can reduce free radical damage. Can they protect spinal cord neurons against oxidative stress?

Organic tomatoes accumulate more vitamin C, sugars than conventionally grown fruit

Tomatoes grown on organic farms accumulate higher concentrations of sugars, vitamin C and compounds associated with oxidative stress compared to those grown on conventional farms, according to new research.

Antioxidants in pregnancy prevent obesity in animal offspring

New biological research may be relevant to the effects of a mother’s high-fat diet during pregnancy on the development of obesity in her children.

Antioxidants in pregnancy prevent obesity in animal offspring

New biological research may be relevant to the effects of a mother’s high-fat diet during pregnancy on the development of obesity in her children. An animal study suggests that a high-fat, high-carbohydrate diet causes oxidative stress — an excess of deleterious free radicals — during pregnancy, predisposing the offspring to obesity and diabetes. Feeding rats antioxidants before and during pregnancy completely prevented obesity and glucose intolerance in their offspring.
