Dietary trends come and go, one food group has stood the test of time as a staple in cultures across the globe - grains. National Rice Month and National Grains Month, celebrated in September, offer an excellent opportunity to explore the crucial role of rice and grains in cancer prevention and diet during cancer treatment. In this article, we will delve into the science behind their benefits and share practical advice on how to embrace them for a healthier life, with a focus on cancer prevention and treatment.
Understanding the Role of Rice and Grains in Cancer Prevention
Fiber – A Carbohydrate Your Body Can’t Break Down
Whole grains, such as brown rice, quinoa, and barley, are rich in dietary fiber. Fiber plays a pivotal role in maintaining a healthy digestive system, which is essential for cancer prevention. Insoluble fiber can’t be broken down in water. It’s found in wheat bran, brown rice and couscous and aids in regular bowel movements. A diet high in fiber has been associated with a reduced risk of colorectal cancer, one of the most common forms of cancer worldwide.
Antioxidants - Guardians of Cellular Health
Rice and whole grains contain a plethora of antioxidants, including vitamins, minerals, and phytonutrients. These compounds act as cellular guardians, protecting your body's cells from oxidative damage. Oxidative stress is a known contributor to the development of cancer. Incorporating a variety of grains into your diet ensures you receive a broad spectrum of antioxidants, enhancing your body's natural defense mechanisms.
Blood Sugar Regulation
Rice and whole grains have a lower glycemic index compared to refined grains, helping to regulate blood sugar levels. Maintaining stable blood sugar is essential, as high sugar levels can promote inflammation, a factor linked to growth of some cancers. Choosing whole grains can be particularly beneficial for individuals with a higher risk of developing cancer due to obesity or insulin resistance. Soluble fiber, found in grains such as oats and barley, can be broken down in water and helps regulated blood sugar.
Healthy Fats
Certain grains, like quinoa and oats, contain heart-healthy fats, such as omega-3 fatty acids. These fats have anti-inflammatory properties and may play a role in cancer prevention by reducing inflammation within the body. Inflammation is often considered a driving force behind cancer initiation and progression.
Why Whole Grains Are More Nutrient-Dense than Processed Grains
Before we explore how to incorporate whole grains into your diet, it's essential to understand why they are superior to processed grains. The key lies in the structure of the grain itself.
A whole grain consists of three main parts:
Bran - Nature's Armor
The bran is the outer layer of a grain, rich in fiber, vitamins, minerals, and antioxidants. It provides protection for the seed.
Endosperm - The Energy Core
The endosperm, located in the middle layer, contains starchy carbohydrates, proteins, and small amounts of vitamins and minerals. It serves as a source of energy for the seed.
Germ - The Nutrient Powerhouse
The germ, situated in the innermost part of the grain, is packed with essential nutrients, including B vitamins, vitamin E, healthy fats, and antioxidants. It is the embryo of the seed.
In contrast, processed grains, such as white rice and white flour, have had the bran and germ removed during milling. This process results in a loss of nutrients, leaving behind primarily the starchy endosperm which the body quickly digests resulting in a spike in blood glucose. Processed grains lack the fiber, vitamins, minerals, and antioxidants found in whole grains, making them significantly less nutrient-dense.
What to Look for When Shopping for Whole Grains
When shopping for whole grains, it's essential to make informed choices to ensure you're getting the full nutritional benefits. Here are some tips:
Check the Label
Look for products labeled "100% whole grain" or "100% whole wheat." These labels indicate that the entire grain kernel is present, including the bran, endosperm, and germ.
Read the Ingredients
Examine the ingredient list on packaged foods. The first ingredient should ideally be a whole grain, such as whole wheat flour or brown rice. Be cautious of products that list "enriched" or "refined" grains.
Look for the Gold Stamp
The Whole Grains Council's "Whole Grain Stamp" is a gold or black stamp found on many whole grain products. It provides information about the amount of whole grains in the product, making it easier to make informed choices.
Buy in Bulk
Consider purchasing whole grains, such as brown rice, quinoa, or oats, in bulk. This not only reduces packaging waste but also allows you to store and use them as needed.
Experiment with Ancient Grains
Don't limit yourself to the familiar. Explore ancient grains like farro, spelt, and amaranth for unique flavors and nutritional benefits.
Cooking Grains: Quick and Easy with Rice Cookers and Instant Pots
Preparing whole grains can be a breeze with the help of modern kitchen appliances like rice cookers and Instant Pots. These devices take the guesswork out of cooking grains, ensuring perfect results every time. Simply add your grains, water, and a pinch of salt, and let the appliance do the work. Not only do these appliances save time, but they also free up your stovetop and allow you to focus on preparing complementary dishes to enhance your meal's nutritional value. I like to put rice in the Instant Pot and cut and stir-fry while it cooks.
Food Safety is Paramount
It's crucial to underscore the importance of food safety when preparing and storing grains. Always wash them thoroughly in a mesh strainer before cooking and follow recommended cooking instructions to eliminate any potential contaminants. After cooking, promptly refrigerate any leftover grains to prevent bacterial growth. Cooked grains can generally be safely stored in the refrigerator for up to four to six days. Ensuring the safety of the grains you consume is an essential part of maintaining overall health, especially for individuals undergoing cancer treatment, as a compromised immune system may be more susceptible to foodborne illnesses.
