What is Clinical Nutrition?

Clinical nutrition is the field that applies knowledge of human nutrition to improve patient outcomes. It emphasizes the role food plays in health through the utility and necessity of specific vitamins and minerals. It helps individuals understand how particular ingredients found in foods and beverages can help or harm them. Clinical nutrition companies should integrate current, high-quality, peer-reviewed research to create products that optimize patient well-being. CF Nutrition products are all formulated explicitly with this philosophy at its core.

Why does Clinical Nutrition matter?

Clinical nutrition addresses the serious and often urgent need to address nutrient deficiencies in a clinical environment. Prior to or following a procedure is just one example of a delicate moment when having good nutritional standing can play a vital role in a patient’s healing. At CF Nutrition, we don’t create beverages based on diet fads or mainstream food trends. Instead, our products use high-quality research with strong data to offer products that are backed by science. We believe this approach can make a real difference in the health outcomes of our customers.

Surgery

Drinking a clear, carbohydrate beverage free from any colors or dyes is safe for healthy individuals before surgery. Research shows that those who consume a clear carbohydrate rich drink up to two hours before surgery are not at risk for aspiration. The clear liquid should not be alcohol. Consult with your doctor to ensure drinking CF (Preop)® is right for you.

Before surgery, it is essential that patients only consume beverages that are 100% clear and colorless. This means no neon-colored sports drinks or colorful hydration solutions.

What does this mean for you? It means that we skip the colorful dyes and harmful additives. We avoid artificial food colorants like Red#40 and Blue#3, known allergens that can negatively impact young children. We add vitamins and minerals derived from plants and sweeten our products with natural stevia. At CF Nutrition, we believe in creating products that provide our customers with everything they need, and nothing that they don’t.

Because consuming a carbohydrate rich drink up to two hours prior to surgery challenges surgical doctrine, many surgeons still recommend NPO after midnight. However, the traditional NPO fast is a dated practice that is no longer the standard in surgery. Modern medical research has revealed safe and often beneficial alternatives to fasting, including complex carbohydrate loading with a clear liquid solution. Foregoing the NPO fast has been associated with less hunger and feelings of stress before surgery, among other positive benefits.

For colonoscopy preparation, we recommend using our complete CF(Colonoscopy Kit)®, which includes two bottles of CF (Rehydrate)® and an oral laxative solution. If you already have a doctor prescribed oral laxative solution, we recommend using CF(Rehydrate)® as a chaser to the laxative. For more information on Colonoscopy Prep and the CF(Colonoscopy Kit)®, please visit the following page.

After wisdom teeth surgery, patients follow a liquid diet for several days.

CF(Preop)®

CF (Preop)® is suitable for healthy individuals preparing for surgery.

According to the most recent guidelines for perioperative care in gynecology & oncology, it is recommended that cancer patients follow the standard ERAS protocol for preoperative fasting and carbohydrate treatment. A clear, colorless beverage such as CF(Preop)® may be safely consumed up to two hours before surgery. Avoiding the harmful NPO fast can help reduce the negative implications and catabolic response associated with extended preoperative fasting. CF(Preop)® may also help patients stay hydrated and nourished, thus reducing feelings of stress related to prolonged surgery preparation. Please note that oral carbohydrate solutions should not be consumed by cancer patients with delayed gastric emptying or gastrointestinal motility disorders. Please consult your physician to ensure CF(Preop)® is a good option for you based on your treatment plan and nutrition needs.

CF (Protein)®

CF (Protein)® can be consumed as an on-the-go snack or occasional meal replacement. For healthy individuals and those with nutrient deficiencies, it is an excellent addition to ensure a well-rounded, nutrient-dense meal. It contains an abundance of vitamins and minerals derived from fruits and vegetables, along with other healthful antioxidants and anti inflammatory ingredients.

CF (Protein)® gets its vibrant yellow color from the naturally vibrant herb, turmeric. Rather than use artificial colors or additives, we use turmeric because of its powerful antioxidant and anti-inflammatory properties that promote healing and restoration for our customers.

Pea protein contains all nine essential amino acids. It is easily digestible and has a pleasant taste and texture. Additionally, it is a good source of iron and other nutrients. Unlike other protein powders like whey, pea protein is not a derivative of milk so it can be consumed by those with allergies or following a specialty diet (vegan, vegetarian, paleo, etc.)

Chia seeds are small black or white seeds derived from the annual from an annual herbaceous plant Salvia hispanica L. The oil from these seeds included in CF(Protein)®  contains healthy omega-3 fatty acids, especially alpha-linolenic acid (ALA). These essential amino acids are associated with brain and heart health, as well as decreased inflammation. Omega 3’s are essential to your diet and can help increase HDL (good cholesterol), reduce blood pressure, and reduce triglycerides- all ways to reduce your risk for cardiovascular disease.

Turmeric contains a powerful active component called curcumin. Curcumin is what gives turmeric its bright yellow hue and can be found in other spices like cinnamon. Although research is ongoing, studies have demonstrated turmeric’s powerful ability to reduce painful inflammation throughout the body. Turmeric may also help lower cholesterol and triglyceride levels.

CF(Protein)® contains the anti-inflammatory and antioxidant rich spice, turmeric Unfortunately, if you are receiving chemotherapy, it may not be recommended for you to consume turmeric.

When speaking to your physician about if turmeric is safe for you, there is 0.3g of turmeric in one bottle of CF(Protein)®. With this information, your oncologist should be able to determine if our product is right for you.

CF(Preop)® is safe for consumption up to two hours prior to your colonoscopy procedure start time, however it is not an oral laxative and therefore should not be taken in place of your prescribed laxative solution.

CF (Rehydrate)® & CF (Rehydrate)® IMMUNITY+

CF (Rehydrate)® and CF (Rehydrate)®Immunity+ are both optimal formulations for medical-grade hydration, however our Immunity+ formula contains an additional dose of Vitamin C, Vitamin D, Magnesium & Zinc to support customers’ immune health.

Symptoms of dehydration include fatigue, heat intolerance, burning sensation in the stomach, and flushed skin. More severe dehydration or heat stress symptoms include difficulties swallowing, loss of balance, delirium, sunken eyes and dim vision, or painful urination. It is best to treat dehydration by drinking a combination of water, salt, and electrolytes such as potassium and selenium.

Water is an essential part of human health. However, our bodies are made up of much more than just H2O. An adequate balance of water and electrolytes is crucial for many of our body’s most important functions. Electrolytes are minerals (sodium, potassium, magnesium, etc.) that are  involved in an abundance of internal events, such as neurotransmission and maintaining a balanced pH in the blood. CF(Rehydrate)® is an excellent source of concentrated electrolytes for medical grade hydration.

Electrolytes are essential minerals that help regulate a variety of essential functions throughout the body. The most common electrolytes you will hear about are sodium, potassium, phosphorus and magnesium. If any of these are too high or too low in your body, you may be at risk for health issues. This is because they contribute to the body’s overall pH balance and must be maintained for healthy physiological function. Electrolytes lost in sweat or from illness should be replenished as quickly as possible.

When you exercise, you lose a significant amount of vital fluids and key electrolytes. High concentrations of sodium and chloride, and low concentrations of potassium, magnesium and calcium are lost as you sweat. Rapidly replenishing these nutrients with a hydrating drink is essential for recovery.

During pregnancy, many expectant mothers will vomit regularly. You may also experience frequent urination or increased sweating during this time. Increased fluid loss can result in serious dehydration, making you feel even worse. Combat dehydration with natural CF(Rehydrate)® to replenish and restore lost electrolytes, including sodium, potassium and magnesium.

Alcohol is a diuretic, meaning it increases urine output and, after a night of drinking, can leave your body extremely dehydrated. This may result in headaches or a variety of other unpleasant symptoms. CF(Rehydrate)® makes bouncing back a breeze with 32 fluid ounces of liquid that is concentrated with electrolytes. This natural beverage provides medical grade hydration, resulting in superior rehydration to sugary sports drinks or water alone.

There is no such thing as a cure for the common cold. However, research has shown that Vitamin D, vitamin C, and Zinc all play a role in supporting the immune system’s response to illness. Each of these nutrients is associated with the prevention and treatment of the common cold. Supplementing these nutrients may help shorten the duration of symptoms.

Dehydration is a common side effect of cancer treatment due to increased incidence of committing, diarrhea, or excessive urination. Every individual will react to cancer treatment differently, making it essential that you regularly check in with your physician to ensure you are taking the right steps to avoid or treat dehydration. The need for fluid intake depends on many variables, including the type of cancer treatment and individual symptoms. CF(Rehydrate)® is a medical-grade, oral rehydration solution that may help cancer patients reduce the chances of becoming dehydrated. It contains an abundance of natural electrolytes, like sodium and magnesium, and carbohydrates. Because every cancer experience is different, CF Nutrition recommends you provide your physician or dietitian a copy of the CF(Rehydrate)® nutrition information before consumption.
