How to enhance antioxidant intake and nutrition?
Different foods contain antioxidant compounds and sometimes eating several foods at once may enhance the amount of antioxidants your body gets.
- Fruits (raspberry, blackberry, and apple)
- Vegetables (broccoli, tomato, mushroom, and purple cauliflower)
- Legumes (soybean, adzuki bean, red kidney bean, and black bean)
Scientists studied how total phenolic content, ferric reducing antioxidant power, 2,2-diphenyl-1-picrylhydrazyl, radical scavenging capacity, and oxygen radical absorbance capacity across food categories changed when the foods were eaten together.
The study found that combining specific foods across categories (e.g., fruit and vegetables) was more likely to result in additive antioxidant capacity
So your daily food antioxidant intake may be enhanced by mixing the right categories of food.

How Coffee Protects Against Diabetes
Coffee helps increase the circulating amount of a protein called sex hormone–binding globulin (SHBG). This protein, according to research studies, has shown to be involved in the development of type 2 diabetes and it is also responsible for the testosterone and estrogen in the human body. Previous research has shown that coffee consumption prevents high-blood sugar and also improved insulin sensitivity. Consumption of decaffeinated coffee was not significantly associated with SHBG levels, nor diabetes risk. Coffee contains magnesium which is known to help with carbohydrate metabolism. Some studies have shown that antioxidants known as lignans or chlorogenic acids may be involved in helping to reduce diabetes.

Peaches, plums and nectarines for carotenoids
Vegetables and fruits are rich in carotenoids. These are antioxidants that reduce damaging compounds when the body is combating disease. A new study shows skin radiance is affected by the carotenoid pigments in fruits like plums, peaches and nectarines.

Healthy Benefits of Eating Tomatoes
Tomatoes have 9-oxo-octadecadienoic acid, a compound with anti-dyslipidemia properties that may prevent vascular diseases. Another nutrient is lycopene, a natural antioxidants. Research shows that tomato consumption has been associated with decreased risk of breast cancer, head and neck cancers and various neurodegenerative diseases
