High protein diet in digestive cancers.
1Department of Translational and Precision Medicine, Sapienza University, Rome, Italy.
Summary
High protein diets are crucial for patients with digestive cancers to maintain nutritional status and improve clinical outcomes. Animal proteins should form the majority of intake, especially during and after cancer treatment.
Area of Science:
- Oncology
- Nutrition Science
- Gastroenterology
Background:
- Nutritional management is vital for patients with digestive cancers.
- Protein intake modulation shows potential for significant nutritional and clinical benefits.
Purpose of the Study:
- To review evidence and derive an optimal protein intake strategy for digestive cancer patients.
- To guide nutritional management for improved patient outcomes.
Main Methods:
- Systematic review of available scientific evidence.
- Analysis of quantitative and qualitative protein intake recommendations.
Main Results:
- High protein diets (1-1.5 g/kg/day) are recommended for adequate nutritional status and clinical benefits.
- Animal proteins should constitute the majority of protein intake.
- High protein intake is particularly important during and after cancer treatments for malnourished or older patients.
Conclusions:
- High protein intake, primarily from animal sources, should be recommended for digestive cancer patients.
- Clinical prescription requires consideration of individual patient needs.
- Optimal protein intake timing and levels throughout the cancer journey require further investigation.

01:02Protein Digestion
105.4K
Protein digestion begins in the stomach, where the highly acidic environment can easily disrupt protein structure by exposing the peptide bonds of polypeptide chains. After polypeptide chains are broken into individual amino acids by a series of digestive enzymes, the amino acids are transported to the liver via the bloodstream to produce energy.

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

72.3K
The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

01:21Overview of Protein Metabolism
1.8K
Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...

3.9K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
