This month we will be discussing another member of the antioxidant family: Vitamin E! Vitamin E, also known as alpha-tocopherol, is a fat-soluble vitamin, which means it requires fat in the diet in order to be absorbed by the body. In addition to its role as an antioxidant, vitamin E is important for immune function and can help to prevent plaque formations within blood vessels [i].

Vitamin E Deficiency
In cancer, supplementation of any antioxidant, including vitamin E, is currently not recommended, unless under the direction of you healthcare practitioner. As discussed in previous months, antioxidants in the form of supplements have the potential to inhibit the effectiveness of chemotherapy and radiotherapy treatments, however food sources of antioxidants have not been shown to have this same negative effect [ii].
Vitamin E is also a fat soluble vitamin, which means that patients who are having difficulties with fat absorption such as those with pancreatic or hepatic (liver) cancer may experience a deficiency of vitamin E. It should be noted however that overt vitamin E deficiency is incredibly rare and even those who consume a diet low in vitamin E rarely develop a deficiency. This tends to be the case with most, but not all, fat soluble vitamins. Signs of a vitamin E deficiency can often mimic the side effects of chemotherapy and radiotherapy treatments, which is why it is always very important that you discuss any of your symptoms with your doctor. Symptoms include: numbness or tingling of the extremities, heart palpitations, vision changes and increased infection [i].
** If instructed by a medical professional to take a vitamin or mineral supplement, it is important that these instructions are followed. In some cases, food sources of vitamins and minerals will not be sufficient for addressing nutritional inadequacies. **
Sources of Vitamin E
Below is a list of the most common food sources of vitamin E:
- Wheat germ
- Sunflower seeds
- Peanut butter
- 3 cups chopped strawberries
- 1/3 cup whole rolled oats
- 1/3 cup chopped pistachios
- ¼ cup all-purpose flour
- ¼ cup brown sugar
- ½ teaspoon cinnamon
- 1 tablespoon sesame seeds
- 1/8 teaspoon salt
- 3 tablespoons butter
- 1 tablespoon water
- Whipped cream or ice cream for serving (optional)
- Preheat the oven to 350 degrees and lightly grease a pie pan.
- In a food processor, pulse the oats, pistachios, flour, brown sugar, sesame seeds, cinnamon, and salt until combined. Add the butter and pulse again. Add the water and pulse again. This mixture should be fairly crumbly but should stick together when pressed.
- Place the chopped strawberries in the bottom of the pie pan and top with the crumble mixture.
- Bake for 20 minutes or until the fruit is bubbly and the topping is lightly browned. Remove from oven and let cool for 10 minutes before serving. Enjoy!
