To further clarify the above and other advantages and features of the one or more embodiments of the present invention, a more particular description of the one or more embodiments of the present invention is rendered by reference to specific embodiments thereof, which are illustrated in the appended drawings. It should be appreciated that these drawings only depict typical of the one or more embodiments of the present invention and are therefore not to be considered limiting in its scope. The one or more embodiments of the present invention are described and explained with additional specificity and detail through the use of the accompanying drawings listed below.
Dry bean (Phaseolus vulgaris L.) consumption has shown chronic disease fighting activity in humans, as they are low glycemic index food with protein, fiber, minerals, essential vitamins, and bioactive compounds. However, Phaseolus vulgaris L. have gone unnoticed for use in non-human commercial food and feed formulations. Despite the success of plant-based nutrients in dog food, dry bean, Phaseolus vulgaris L., a food crop of global agricultural and nutritional importance, has not been exploited for use in commercial pet food formulations.
Phaseolus vulgaris L. was selected for the two experimental studies because of its reported health benefits and availability in cooked and dehydrated powdered form. Digestibilities of the starch and fiber components of uncooked (emphasis added) legumes have been evaluated for canines and exhibited lower digestibility when compared to other carbohydrate sources. Bednar, G. E., et al. J. Nutr. 131:276-286 (2001). Additionally, uncooked legumes (beans and/or peas) have been known to increase flatulence because of their high fiber content.
The prevalence of obesity and/or associated metabolic disorders has increased for humans and non-humans alike. Obesity, a term which is well-known in the art, represents a serious threat to the health of animals because it increases the likelihood of associated diseases, such osteoarthritis, insulin resistance, hyperglycemia, cardiac dysfunction, respiratory disease, cranial cruciate ligament injury, kidney disease, and cancer. Lack of exercise and excess food often lead to weight increase. These diseases can be measured not only physically, but biochemically using biomarkers.
A biomarker is a parameter, chemical, physical, or biological, that can be used to measure the progress of disease or the effects of treatment. Biomarkers, for example, can help in early diagnosis, drug target identification, disease prevention, and drug response. Disease related biomarkers can give an indication of how a disease may development in a subject, or the probable effect of treatment on a subject. This in turn can help make decisions in the diagnosis of a disease or condition and the course of treatment for a subject. Several biomarkers have been identified for many diseases and are well-known in the art. The level of these biomarkers in a subject's blood serum is a good indication of whether the subject is for example, a healthy weight, or overweight.
Table 1 shows a list of several important biomarkers for animal health, using canines as an example. The biomarker type is shown in column one, column two shows the level of the biomarker in obese dogs, and column three shows the level of the biomarker in dogs after weight loss.
Alkaline phosphatase or ALP, is a hydrolase enzyme responsible for removing the phosphate groups from a variety of molecules. Elevated levels of ALP may indicate blockage in the bile ducts of the liver, for example.
Cholesterol is a waxy steroid of a fat and is formed predominantly in the liver of vertebrates. Cholesterol is an important component of cell walls, however, high cholesterol levels have been linked to diseases such as cardiovascular disease, obesity, and cancer.
Triglycerides are an ester derived from glycerol and attached to three fatty acids. High levels of triglycerides have been linked to obesity.
Total protein is the total amount of protein in the blood. A total protein test report separates values for total protein, albumin, and globulin.
Albumin is one of the two major proteins in the blood and is made mainly in the liver. It promotes tissue growth and healing.
Calcium is one of the most abundant minerals found in the body, and is primarily stored in the bones and the teeth.
Phosphorous is a mineral that is important for the formation of bones and teeth, but also functions in the body's use of carbohydrates and fats, synthesis of protein, proper functioning of the kidneys, and cardiovascular maintenance.
Glucose is a simple sugar and is a primary source of energy for the body. High levels of blood glucose in blood serum may be a sign of pre-diabetes or diabetes.
Creatinine is a breakdown product of creatine and is usually indicative of good kidney function. If high levels of creatinine are present in the blood, then this may indicate that kidney function is abnormal.
Blood urea nitrogen measures the amount of nitrogen in your blood, as a waste product derived from the production of urea. Elevated levels may indicate abnormal kidney function or heart failure, for example.
Chloride is one of the most important electrolytes in the body and is measured in either the blood or urine. It helps maintain proper fluid balance, blood pressure, and blood volume in the body.
Globulin is one of the two major proteins in the blood and is made up of alpha, beta, and gamma type proteins. Certain globulins are made by the liver, while others are made by the immune system.
Alanine aminotransferase or ALT, is an enzyme mainly found in the liver, but also found in lesser amounts in the pancreas, muscles, heart, and kidneys. A test for this enzyme is usually done to determine the relative health of the liver.
Sodium is an element that is important for maintaining a body's proper blood volume and pressure, but is also essential to the proper function of the body's nerves and muscles.
Magnesium is an essential mineral that is important for the proper function of muscle contraction and relaxation, protein production, and numerous biochemical reactions in the body.
Potassium is an important mineral for the proper function of all cells, tissues, and organs in the human body. It is essential for proper heart function, kidney function, and muscle relaxation and contraction.

Two experimental studies were conducted to establish the safety and digestibility of cooked navy bean powder when incorporated into a canine diet formulation when compared to a macro and micro-nutrient matched control. The total length of each study was 28 days. Blood parameters were measured with standard clinical operating procedures at the Clinical Pathology Laboratory at Colorado State University. The biochemistry panel was analyzed using a clinical chemistry analyzer (Hitachi 917; Roche Diagnostics, Indianapolis, Ind.) and cell blood counts (CBC) was detected using an analyzer (Advia 120; Bayer, Tarrytown, N.Y.). All parameters required by the Association of American Feed Control Officials (AAFCO) were included in this panel. Blood and urinalysis was measured at baseline (zero weeks), 2 weeks post treatment, and 4 weeks post treatment. Fecal collection was taken at baseline to determine if there were any health problems in the subject canines. Control, cooked, dehydrated and powdered navy bean diet or cooked, dehydrated, and powdered black bean powder diet were given to the canine subjects at day 1. On day 7, the canine subjects were weighed. On day 14, canines were given a physical exam, and blood and urinalysis was taken. Fecal collections, or stool samples, were collected from day 14 through day 18 for digestibility analysis. On day 21, the canine subjects were weighed. On day 28, the last day of the study, canine subjects were given an exit examination and blood, urinalysis, and a fecal collection were taken.
Twenty-one healthy, adult, free-living dogs were recruited to participate in a randomized, double blinded, and placebo-controlled canine dietary four week intervention study. All clinical trial operations, animal care procedures and collection of biological samples were approved for safety and digestibility of experimental research diets. Dogs were randomized in a 1:1 manner for equal allocation to study diets “A” or “B” and a body condition score or BCS, was determined by the study clinician during the baseline physical exam. BCS was measured on the following 9-point scale: 1-2=emaciated, 2-3=thin, 4-5=normal/moderate, 6=stout, 7=overweight, and 8-9=obese. Each dog received a study code number and both the owner and clinician were blinded to the assigned study arm.
Table 2 shows the age, weight, body condition score, and gender of the 21 canine dietary intervention study participants. The sample size for the cooked, dehydrated, and powdered navy bean diet was 10 canines and the sample size for the control diet was 11. Differences in age, weight, and BCS were not significant between the two diet groups (P>0.05).
Table 3 shows the breed of the 21 canine study participants. Column one shows the breed, column two shows the number of that breed in the cooked, dehydrated, and powdered navy bean diet, and column three shows the number of that breed in the control diet.
The compositions of the two canine formulations can be prepared either in wet or dry form, using conventional processes known to those skilled in the art. Two canine diet formulations were used in this study that meet the nutritional recommendations according to AAFCO 2008 Official Publication feeding guidelines. A formula similar to a commercially available adult canine diet formulation 27/12 (Archer Daniels Midland (ADM) Alliance Nutrition) was used for the 0% cooked, dehydrated, and powdered navy bean, placebo control. This formulation was used because it is an existing diet formulation of carbohydrate/fat ratio to compare to a formulation containing cooked, dehydrated, and powdered Phaseolus vulgaris L. The control diet was mixed and manufactured under the same conditions and locations as the cooked, dehydrated, and powdered navy bean diet. Diets were mixed and extruded in St. Charles, Mo. The cooked, dehydrated, and powdered navy bean diet was formulated to match the control diet in macronutrient and caloric content, except for the inclusion of 25% cooked, dehydrated, and powdered navy bean (VEGEFUL ADM Edible Bean Specialties, Decatur, Ill.). Both diets were prepared as dry food. Adjustment of major food ingredients, such as wheat and corn, were made to account for differences in the contribution of cooked, dehydrated, and powdered navy bean to macro and micronutrients and total caloric contents. The fatty acid content of both diets was matched as well. Marine-type long chain n−3 fatty acids were not present in either diet. The lipid profile of the diets was determined.
Both the cooked, dehydrated, and powdered navy bean diet and the control diet were given on an as-fed basis. The percentages of ingredients are listed for each study in Table 4. In Table 4, column one shows the ingredient, column two shows the percentage or unit of the ingredient in the total formula, column three shows the percentage or unit of the ingredient in the cooked, dehydrated, and powdered navy bean diet, and column four shows the percentage or unit of the ingredient in the control diet. LA is abbreviated for linoleic acid, ALA is abbreviated for alpha linoleic acid, AA is abbreviated for arachidonic acid, EPA is abbreviated for eicosapentaenoic acid, DHA is abbreviated for docosahexaenoic acid, K stands for kilo, and IU stands for international unit.
In Table 5, the organic matter, ash content, crude protein content, acid hydrolyzed fat, total dietary fiber, and gross energy were compared between the cooked, dehydrated, and powdered navy bean diet and the control diet. Column one shows the macro ingredients, column two shows the unit of the macro ingredient, column three shows the percentage or unit of the macro ingredient in the total formula of the cooked, dehydrated, and powdered navy bean diet, and column four shows the percentage or unit of the macro ingredient in the total formula of the control diet.
Canine owners were instructed to feed only the research diet provided by study clinical coordinator for the entire study duration and to measure out a prescribed amount of food for canine consumption each day. The prescribed daily caloric consumption was determined by body weight and according to the canine's normal feeding habits (i.e., one or two feedings daily). Water was provided ad libitum. The total required daily caloric intake for each dog was calculated at the baseline study visit using the following formula:
kcal=110×Body Weight(kg)0.75
This formula was used to maintain a stable weight in canines for the study duration. An inappropriate weight change was defined by a change of more or less than 2% per week or 4% change from each visit. Canine owners measured and recorded the volume of food offered and refused. The total amount consumed was calculated by subtracting the weight of the refused food from offered food. The canine owner completed a daily intake record for 28 days and a space was provided to record any intake from research diet that may impact study results.
Blood samples were collected via jugular puncture at baseline, 2 weeks, and 4 weeks post intervention. At each visit, 1 mL of whole blood was collected into an evacuated red top tube without anticoagulant for biochemistry panel analysis. Another 1 mL of blood was collected into an evacuated lavender top tube containing EDTA (ethylenediaminetetraacetic acid) for complete blood counts (CBC), hemoglobin, and hematocrit determination.
Canine owners reported daily fecal scores using the following 3-point scale: 1=well formed, 2=soft, and 3=runny. A comment space was provided on the score sheet to obtain any observational changes per the owner's discretion. A four day (96 hour) total fecal collection was performed for the measurement of apparent macronutrient digestibility after 10 days of consuming 100% of the investigational, placebo control or the cooked, dehydrated, and powdered navy bean-containing, diets. Samples were collected daily and stored at −20° C. At the end of the collection period, the samples were weighed, pooled, and stored at −20° C. and then freeze-dried prior to proximate analysis. Urine samples were usually collected by the owner at home using provided specimen containers. In some cases when the owner was unable to obtain a urine sample, ultrasound guided cystocentesis was used.
Proximate analysis of both of the research diets, and the 96 hour pooled fecal samples were performed according to AOAC (Association of Official Analytical Chemists) standard methods. Organic matter was calculated by subtracting ash from dry matter (DM). Gross energy was measured using oxygen bomb calorimetry. Crude fiber content was determined using the ANKOM Technology Crude Fiber Method. Study samples were coded and blinded for proximate analyses were performed.
Digestibility of protein, fat, carbohydrate, and total DM were calculated by the following formula where nutrients were measured in grams on a DM basis:
Nutrient digestibility(%)=((nutrient intake-nutrient in feces)/nutrient intake)×100
Metabolizable energy was calculated by the following formula:
Metabolizable energy=[Gross energy of food consumed−gross energy of feces collected−{(grams of protein consumed-grams of protein in feed}×correction factor for energy lost in urine)]/grams of food consumed×10002.
Food consumption was determined by recording feed intake, and dry matter fecal values were used. The correction factor for energy lost in urine was 1.25 kcal/g2.
A diverse set of breed participants were recruited for the first experimental study to provide broad representation of the canine population. Table 2 shows the mean age and standard error of the mean (SEM) age in years, weight in kilograms, median body condition score (BCS), and gender by study arm of the 21 dogs who participated in the study. No significant differences were determined at the baseline across treatments. The breeds of all dogs that participated in the study are listed in Table 3. Ten different known breeds and several mixed breeds were represented in the study in both diet groups.
In order to assess the safety of the 25% weight/weight cooked, dehydrated, and powdered navy bean dietary intake compared to a 0% bean, placebo control canine diet, blood diagnostic tests were conducted for all study participants at baseline, 2 weeks, and 4 weeks post intervention. No significant changes in AAFCO test protocol parameters including packed cell volume (PCV), hemoglobin (HGB), serum albumin concentrations, and serum alkaline phosphate activities (ALP) across treatments were detected. Additionally, no parameters were significantly changed or outside of the normal range in any of the dogs from baseline.
Table 6 shows the average serum levels of HGB, PCV value, albumin, and ALP for both groups at baseline, 2 weeks, and 4 weeks with the laboratory reported normal ranges. Column one shows the parameter measured, columns two and three show the mean value and SEM of the baseline value of the parameter for the cooked, dehydrated, and powdered navy bean diet, respectively; columns four and five show the mean value and SEM of the baseline value of the parameter for the control diet, respectively; columns six and seven show the mean value and SEM of the two week value of the parameter for the cooked, dehydrated, and powdered navy bean diet, respectively; columns eight and nine show the mean value and SEM of the two week value of the parameter for the control diet; columns ten and eleven show the mean value and SEM of the 4 week parameter for cooked, dehydrated, and powdered navy bean diet, respectively; columns twelve and thirteen show the mean value and SEM of the 4 week parameter for the control diet, respectively; and column fourteen shows the normal ranges for each parameter. Significance was tested by a one factor ANOVA across diet and time point. Differences between diet and time point were not significant (P>0.05, n=10).
In addition to the AAFCO required hemoglobin and packed cell volume, a full CBC and biochemistry profile were conducted to determine safety as shown in Tables 7 and 8 for the control diet and the cooked, dehydrated, and powdered navy bean diet, respectively. In Tables 7 and 8, column one shows the parameter measured, columns two and three show the mean and SEM value of the parameter at baseline, respectively; columns four and five show the mean and SEM value of the parameter at two weeks, respectively; and columns six and seven show the mean and SEM value of the parameter at four weeks, respectively; and column eight shows the normal ranges for the parameter. No significant adverse changes were observed in any of these parameters between the experimental diets and all parameters were determined to be within normal ranges, except for cholesterol levels, which were shown to be significantly different between the experimental diets.
Although a urinalysis is not a required outcome criteria according to AAFCO guidelines for assessing safety of new dietary formulations, this additional safety measure was applied herein given the potential for beans at 25% weight/weight of diet to modulate overall metabolic status as well as liver and kidney metabolism. Urinalysis was conducted at baseline, 2 weeks, and 4 weeks intervention on all participants, where the results of USG (urine specific gravity) and urinary pH are shown in Table 9. Column one shows the parameter; columns two and three show the value and the SEM for the parameter at baseline for the cooked, dehydrated, and powdered navy bean diet, respectively; columns four and five show the value and SEM for the parameter at baseline for the control diet, respectively; columns six and seven show the value and the SEM for the cooked, dehydrated, and powdered navy bean diet at 2 weeks, respectively; columns eight and nine show the value and the SEM for the control diet at 2 weeks, respectively; columns ten and eleven show the value and the SEM for the cooked, dehydrated, and powdered navy bean diet at 4 weeks, respectively; and columns twelve and thirteen show the value and the SEM for the control diet at 4 weeks, respectively.
All parameters were determined to be within normal and no significant differences were observed between groups. An intriguing trend was observed for urine pH such that the cooked navy bean powder diet group had an average pH at baseline 6.5 that decreased after 2 weeks to 5.5, and then normalized to an average baseline value of 6.5 at 4 weeks' time point. The control group demonstrated an opposite trend whereby the average urine pH was 6 at baseline, increased to a pH of 7 at 2 weeks, and then returned to urine pH of 6 at 4 weeks. There is no clinical significance for this transient response in urine pH between the cooked, dehydrated, and powdered navy bean diet and the control diet groups because both groups normalize at 4 weeks. These findings were reported herein as the experimental relevance of the acidic, yet transient urinary response to navy bean consumption may be important for future clinical dietary bean investigations.
No significant differences in macronutrient intakes, apparent digestibility, fecal characteristics, and metabolizable energy were observed between the cooked, dehydrated, and powdered navy bean diet and control diet as shown in Table 10. In Table 10, column one shows protein, fat, and organic matter intakes; columns two and three show the mean values and SEM for the cooked, dehydrated, and powdered navy bean diet; and columns four and five show the mean values and SEM for the control diet. The standard error of the mean (SEM) for the cooked, dehydrated, and powdered navy bean diet was a sample size of 10, and the standard error of the mean (SEM) for the control diet was for a sample size of 11. Significance for intake, output, digestibility, and metabolizable energy were analyzed with a 2-factor ANOVA followed by Bonferroni's multiple comparison test. Significance for fecal scores was analyzed using an un-paired t-test. No significant differences (P<0.05) were found between groups.
As shown in Table 10, protein, fat, and organic matter intakes are reported on a dry matter basis. AAFCO metabolizable energy calculations assume apparent digestibility of 80% for protein, 90% for crude fat, and 84% for organic matter. Cooked, dehydrated, and powdered navy bean diet apparent digestibility was close to these values with the exception of organic matter, which was slightly lower. Average navy bean powder intake per kilogram of body weight was 3.7 g/day. Two dogs, one from each group, increased weight by 4% at the 2 week time point and the prescribed amount of food was reduced by 37.5 g for the cooked, dehydrated, and powdered navy bean diet and 32.6 g for the control diet. All other dogs maintained weight throughout the study of the duration.
As shown in Table 10, The metabolizable energy of the control diet are less than the cooked, dehydrated, and powdered navy bean diet due to one participant who ate a non-specified amount of high-energy horse feed during the 96 hour collection period. Exclusion of this datum results in a calculated metabolizable energy of 3288 kcal/kg±183. The total amount of fecal matter and fecal quality scores did not change between the two groups. An isolated incidence of vomiting and diarrhea was reported in both groups, and were reported as unrelated to diet by owner. None of the owners reported increased incidence of flatulence and both diets were reported as equally palatable to all study participants based on no differences detected in reported dietary intake or eating preferences determined by dog owners.
Additionally, similar metabolome characteristics were reported for both cooked, dehydrated, and powdered navy bean diet and the control diet, as shown in
Data from the first experimental study indicate that the results provide compelling support for the safe incorporation of dietary cooked, dehydrated, and powdered navy bean as no adverse changes were detected in diagnostic blood parameters that are routinely examined for the presence of canine disease or illness and an unexpected significant reduction in cholesterol values was shown for the navy bean powder cooked, dehydrated, and powdered navy bean diet.
Twenty-eight healthy, adult, free-living dogs were recruited to participate in a randomized, double blinded, and placebo-controlled canine dietary four week intervention study. All clinical trial operations, animal care procedures and collection of biological samples for safety and digestibility of experimental research diets were approved at a facility in Fort Collins, Colo. Dogs were randomized in a 1:1:1 manner for equal allocation to study diets “A”, “B” or “C” and a body condition score or BCS, was determined by the study clinician during the baseline physical exam. BCS was measured on same scale as the first experimental study. Only dogs with a BCS of 6-9 were enrolled in this study. Dogs with a BCS between 6-9 were randomized equally to each study arm.
Each dog received a study code number and both the owner and clinician were blinded to the assigned study arm.
Table 12 shows the age, weight, body condition score, and gender of 28 canine dietary intervention study participants. Each diet group in the overweight dog study group had a target sample size, n=10 (i.e., the control diet, the cooked, dehydrated, and powdered navy bean diet, and the cooked, dehydrated, and powdered black bean diet). Baseline differences in age, weight, and BCS were not significant (P>0.05) across diet groups.
Given the safety and digestibility of cooked, dehydrated, and powdered navy bean in the first experimental study, a second bean type that is available in the cooked, dehydrated, and powdered form was added for investigation of efficacy in the second experimental study of weight loss. The cooked, dehydrated, and powdered navy bean and black bean diets were formulated to meet the nutritional recommendations according to AAFCO 2010 Official Publication Feeding guidelines. A formula similar to a commercially available adult canine diet formulation 27/12 (ADM Alliance Nutrition) was used for the 0% bean, placebo control. The control diet was mixed and manufactured under the same conditions and locations as the experimental cooked, dehydrated, and powdered navy bean and black bean diets. Diets were dry and mixed in St. Charles, Mo. Both the cooked, dehydrated, and powdered navy bean and black bean diets were formulated to match the control diet in macronutrient and caloric content, except for the inclusion of 25% weight/weight cooked, dehydrated, and powdered navy bean or black bean (VEGEFUL ADM Edible Bean Specialties, Decatur, Ill.). Adjustment of major food ingredients, such as wheat and corn, were made to account for differences in the contribution of cooked, dehydrated, and powdered navy bean and black bean to macro and micronutrients and total caloric contents. The fatty acid content of both diets was matched as well. Marine-type long chain n−3 fatty acids were not present in either diet. The lipid profile of the diets was determined.
All diets (control, and cooked, dehydrated, and powdered navy bean and black bean) were given on an as-fed basis. The percentages of ingredients are listed for each study in Table 13. In Table 13, column one shows the ingredient, column two shows the percentage of the ingredient in the control diet, column three shows the percentage of the ingredient in the cooked, dehydrated, and powdered navy bean diet, and column four shows the percentage of the ingredient in the cooked, dehydrated, and powdered black bean diet. LA is abbreviated for linoleic acid, ALA is abbreviated for alpha linoleic acid, AA is abbreviated for arachidonic acid, K stands for kilo, IU stands for international unit, EPA is abbreviated for eicosapentaenoic acid, DHA is abbreviated for docosahexaenoic acid, and AAFCO ME is abbreviated for Association of American Feed Control Officials ME estimation. The vitamin premix was from ADM Alliance in Quincy, Ill.
The following were provided per kilogram of cooked, dehydrated, and powdered navy bean and black bean diets: vitamin A, 7,500 IU; vitamin D, 750 IU; vitamin E, 93.75 IU; thiamine, 3.75 mg; riboflavin, 30 mg; pantothenic acid, 12 mg; niacin, 15 mg; pyridoxine, 1.875 mg; folic acid, 0.26 mg; vitamin B12, 37.5 μg; choline, 534.4 mg; iron, 292 mg; copper, 15 mg; manganese, 31 mg; zinc, 200 mg; iodine, 2 mg; selenium, 0.7 mg.

The last six rows show the organic matter, ash content, crude protein content, crude fat, crude fiber, and gross energy were compared between the cooked, dehydrated, and powdered navy bean diets and the control diet. Column one shows the macro ingredients, column two shows the percentage of the ingredient in the control diet, column three shows the percentage of the ingredient in the cooked, dehydrated, and powdered navy bean diet, and column four shows the percentage of the ingredient in the cooked, dehydrated, and powdered black bean diet.
Table 14 shows the percentage weight loss of the canine subjects during the four week experimental study. Dietary intake for all dogs in each of the experimental diet groups was calculated according to the following formula: Baseline weight (kg)-(baseline weight (kg)×(0.1 if BCS 6, 0.2 if BCS 7, 0.3 if BCS 8, or 0.4 if BCS 9)).
Caloric intake for most dogs was reduced 40% and the following equation was used to determine the total Kcal/day that each dog needs: (110×(ideal weight̂0.75))×0.6
The total kcal per day was converted to total grams of each diet per day by dividing Kcal per day from Kcal diet per gram weight of diet. These formulas and steps show how the total grams/day that each dog needs to achieve weight loss in the second experimental study was determined.
In Table 14, Column one shows the time frame, columns two and three show the percentage weight loss and the SEM for the control diets, respectively; columns four and five show the percentage weight loss and SEM for the cooked black bean powdered diet, respectively; and columns six and seven show the percentage weight loss and SEM for the cooked navy bean powdered diet.
Results show that by the end of the four week study, canines on the control diet lost 4.04% of their initial body weight, canines on the cooked, dehydrated, and powdered black bean diet lost 5.0% of their initial body weight, and canines on the cooked, dehydrated, and powdered navy bean diet lost more than their other diets counterparts, 6.42% of their initial body weight.

The following list of blood parameters in Table 15 that are included in the metabolic panel are either significant or not significant for assessing metabolic changes during weight loss. This table is used as a guide to assess whether dietary incorporation of cooked, dehydrated, and powdered navy bean or black bean alters metabolic status differently from the control diet during the weight loss process. CSU units are measured as MEQ/L instead of mmol/L. S means significant at the P<0.1 level and NS means not significant
As reported in the first experimental study, a trend toward lower cholesterol was seen in the canines consuming the cooked, dehydrated, and powdered navy bean and black bean diets, as shown in
Table 17 and
Table 18 and
Table 19 and
Table 20 and
Data from the second experimental study further indicate that the results provide compelling support for the safe incorporation of dietary cooked, dehydrated, and powdered navy bean or black bean as no adverse changes were detected in diagnostic blood parameters that are routinely examined for the presence of canine disease or illness and an unexpected significant reduction in cholesterol values was shown for the cooked, dehydrated, and powdered navy bean or black bean diets. These findings support important metabolic changes with Phaseolus vulgaris L. containing diets during weight loss. A number of other blood weight loss biomarkers (i.e., glucose, blood urea nitrogen, alkaline phosphatase) may require more time, about 2-6 months to show significant changes across diet groups.
Additional Experimental Studies Using an Orally Ingested Food Composition Containing Phaseolus vulgaris L.
Orally ingestible formulations containing cooked, dehydrated, and powdered Phaseolus vulgaris L. can also be made for other animals including cats, rabbits, guinea pigs, mice, rats, birds, ferrets, and other domesticated livestock animals such as lamas, alpacas, mules, donkeys, chickens, horses, pigs, sheep, goats, buffalo, cattle and the like, and humans.
