Protein: Animal foods provide predominantly acid precursors, whereas protein in vegetable foods provide base precursors not found in animal foods. Over time, excess dietary acid precursors can lead to an accumulation of acid load that may have adverse consequences for your bones. There is some evidence that a high ratio of dietary animal protein to vegetable protein increases bone loss and risk of fracture in postmenopausal women. A high-protein diet, along with adequate calcium and fruits and vegetables, is important for bone health and osteoporosis prevention. Having a balance of plant to animal protein in your diet is so integral to healthful eating and is especially important for your bones and muscles.

Although there are some general recommendations on the subject, mite cultures may be used as whole cultures, thus containing more fecal material, or sieved, containing more purified mites. Both raw materials are used. Currently, there is a clear trend toward using more purified cultures to avoid the presence of food medium [23]. Mites were first grown on human skin scales collected from barber shops, and on yeast [24]; other food media used included fish food flakes, dried Daphnia, dog food, rodent chow, several cereal preparations, and even mold cultures [25]. Due to their position in the trophic chain, mites mainly feed on proteins found in house and mattress dust. A supplement of yeast is also important to complement the intake of micronutrients. The ingestion of a high-protein diet is a common determinant and is needed for their proliferation. Several food media are currently being used to grow mites. There are general recommendations to avoid the use of human- and other animal-derived proteins. Food media currently used in Europe and the United States include autoclaved pork liver powder and yeast, brine shrimp eggs and yeast, and wheat germ. Other companies produce mites grown on wheat germ, supplemented with amino acids (resembling the composition of human stratum corneum) and baker's yeast [27,28]. The use of a well-defined nonallergic medium is warranted.
The liver, gallbladder and pancreas

Carcinoma of the pancreas is one of the most aggressive malignant tumours with poor outcomes. It has doubled in incidence in the UK during the past 50 years. The increase in the USA has been even higher and there it now ranks second only to colorectal carcinoma among alimentary tract cancers. It is more common in males than in females, and increases progressively in incidence after the age of 50 years. Epidemiologically, it has been linked to smoking and a high-fat/high-protein diet. There is an increased risk of pancreatic carcinoma in patients with chronic pancreatitis and particularly those with hereditary chronic pancreatitis. Up to 10% of patients with pancreatic carcinoma have a family history of this tumour, indicating a possible genetic basis that has not as yet been clarified.

A negative correlation was also observed between fatigue scores and muscle mass, although this was not statistically significant. This could imply that by increasing muscle mass among patients with breast cancer, the prevalence of fatigue could be reduced. This is consistent with previous studies that have shown that prevention of sarcopenia and preservation of muscle mass have positive patient-related outcomes, including fatigue (43, 44). A recent study has shown that a high protein diet and not isolated branched chain amino acid can improve the skeletal muscle mass in patients with gastrointestinal cancers (45) while whey protein supplementation is considered excellent for maintaining muscle mass even under caloric restriction (46). Protein source is a topic of interest for patients and clinicians. A diet rich in plant-derived proteins may support muscle anabolism, albeit requiring a larger quantity of protein to fulfill the recommended intake (47) and therefore a whey-based supplement was added to the intervention protocol to meet the protein requirement. A high protein diet can be a cost-effective way to improve muscle mass rather than focusing on ingestion of supplements. However, whey protein contains branched-chain amino acids, has a high amino acid content, and is digested rapidly, making it a high-quality protein source. Branched-chain amino acids such as leucine are considered major stimulators of muscle protein synthesis (48, 49). A longer study duration may have demonstrated a stronger and statistically significant correlation between muscle mass and CRF.

In contrast, 63 patients reported to adhere to a high-protein diet. Almost 70% of these patients were male and mainly between 10 and 20 years old. Previous studies showed a higher percentage of high-protein diets including the use of protein supplements among young males compared to females, especially in athletes, but also in leisure time exercisers (MRI 2008; Hartmann et al. 2016; Ewan et al. 2019). Their main motives for high-protein diets are often to gain or maintain muscle mass and strength. A former study investigating associations between physical activity and glycemic control in adults with T1D showed that the majority among the group with the highest physical activity (more than two times a week) were young males (30.4 years± 15.8, mean age ± SD) (Bohn et al. 2015). With respect to T1D, a higher protein intake is not necessary (Smart et al. 2018). In contrast, a high protein intake over a longer period might be harmful for patients with T1D and persistent microalbuminuria or apparent nephropathy (Smart et al. 2018) as it might negatively impact renal function (Tipton 2011).

The elimination profiles (Figures 1–6) showed biphasic kinetics in animals supplemented with low and high dietary proteins. As shown in Figure 1, the bile showed significant (p < .05) high-dose excretion of unchanged NDEA when compared with nitrite during low-protein diet after a single intraperitoneal dose of NDEA. The same trend was observed for high-protein diet after a single intraperitoneal dose of NDEA (Figure 2). For low-protein diet, bile excreted a considerably (p < .05) high amount of unchanged NDEA relative to nitrite after a combined administration of a single intraperitoneal dose of NDEA with AFB1 (Figure 3). The same trend was also observed for high-protein diet (Figure 4) following a combined administration of a single intraperitoneal dose of NDEA with AFB1. Generally, as shown in Figures 5 and 6, the rats placed on high-protein diets excreted significantly (p < .05) higher amount of the unchanged NDEA and nitrite in the bile than the lower-protein diet groups in both single and combined administrations of NDEA and/or AFB1. Furthermore, both low and high dietary proteins showed higher-dose excretion of bound NDEA and AFB1 (NDEA-AFB1) in bile than NDEA only (Figures 7 and 8).
