Most people overlooked fiber in their diet and many would rather not think about it. However, fiber deserves our attention because of the health benefits it contributes. For optimum health, 25-30 g of fiber a day is required in our diet.
What are the benefits of fiber?
1) Protects against breast cancer
Fiber binds excessive estrogen (female hormone) and draws it out of the body. Consumption of 20g of fiber a day reduces the risk of breast cancer.
This is seen from the research study reported in the American Journal of Epidemiology, April 2011, on 86 621 women who eat high vegetables and fruit and low carbohydrate diet was found to reduce the risk of estrogen receptor type cancer.
This also reduces the risk of related diseases such as endometriosis, uterine fibroid and polycystic ovary.
2) Balancing blood sugar level
Keep blood sugar level stable cause the body to store less fat. This also helps behaviour and learning difficulties in children affected by blood sugar swings.
3) Protects cardiovascular system
4) Prevents colon cancer
Fiber acts like a brush that cleans the intestine. The fiber also reacts with the bacteria in the intestine and fermentation produce short chain fat, which helps to maintain intestinal health. It also helps to maintain a healthy population of probiotic bacteria in the digestive system.
Where can you get fiber?
1) Oat and barley
Soluble fiber in oat and barley called beta-glucan helps to reduce cholesterol and stabilizes blood sugar level. 1 bowl of oatmeal gives 3 g of fiber
Bran is the outermost layer of a grain that is typically removed during processing to increase shelf life. ½ a cup of wheat bran cereal contains 13 g fiber.
Seaweed is rich in various types of fibers:
- Agar – from red seaweed, triples in volume when taken with lots of water to give the feeling of fullness.
- Algae and kelp has fiber content that is 32-50% of their dry weight
- Alginate – from brown seaweed, used to increase fiber content in processed food.
Beans are a rich source of fiber and protein. They also contains mineral and vitamins. 1 cup of kidney beans gives 11 g of fiber, which is almost half of the total required.
6) Vegetables and fruits
Most vegetables give 2-3 g of insoluble fiber per serving. Fruits contain insoluble fiber from the skin and soluble fiber in the flesh. The WHO ( World Health Organization) recommends a 7 portions of fruits and vegetables for optimum health.
