Diets inducing obesity, metabolic syndrome and mild NAFLD/NASH

Western and Fast Food diets with milkfat and cholesterol

Western or fast food style diets fed to induce NASH with metabolic syndrome contain 40 – 45% kcal from milkfat (a fat source high in palmitate) with added cholesterol (0.15 – 2%) and are high in sucrose (>30%). Dietary palmitate and cholesterol have both previously been associated with the progression from simple steatosis to NASH.

Examples:

TD.88137?? ? ? Adjusted Calories Diet (42% from fat)
TD.96121?? ? ? 21% MF, 1.25% Chol. Diet
TD.120528? ? ?42% Kcal/Fat Diet (Incr. Sucrose, 1.25% Chol.)

Research use:

These diets can induce obesity, metabolic syndrome, and simple steatosis within nine weeks of feeding. Increased hepatic inflammation has been observed after 12 weeks of feeding. NASH typically requires longer feeding with fibrosis developing within nine months and late stage fibrosis including hepatic ballooning occurring after 14 – 20 months of feeding. Increasing dietary sucrose (~41%) and cholesterol (~1.25%) accelerates the NASH phenotype with steatosis, inflammation and hepatocyte ballooning observed within 12 weeks. In addition to feeding a high fat diet, providing a glucose/fructose mixture in the drinking water may further promote NASH development.

The ALIOS model: western diet with trans-fat

The American Lifestyle-Induced Obesity Syndrome (ALIOS) model involves feeding the “American fast food” diet high in trans-fats and sugar. Dietary trans-fats from hydrogenated vegetable shortening (HVO) are associated with increased insulin resistance and hepatic inflammation in rodent NASH models. In addition to diet, a glucose/fructose solution is added to the drinking water and sedentary behavior promoted by removing the overhead cage feeders in this model.

Examples:

TD.06303?? ? ??22% HVO Diet
TD.120330?? ??22% HVO + 0.2% Cholesterol Diet
TD.130885?? ??ALIOS with Added Sugar

Research use:

The ALIOS model develops obesity with insulin resistance, elevated ALT levels, and steatosis within 16 weeks. Increased inflammation and early development of fibrosis have been observed at 6 months. Severe steatosis with fibrosis and inflammation develops within 12 months of feeding with 50% of the mice reportedly developing hepatic neoplasms. Adding cholesterol (0.2%) to the American Fast Food diet may accelerate NASH phenotype development.

FPC diet: fructose, palmitate, cholesterol and trans-fat diet

The Fructose, Palmitate, Cholesterol and Trans-Fat (FPC) diet is a recent NASH diet that includes Western and ALIOS model diets to achieve both metabolic and hepatic NASH features within an accelerated time frame. Key features of the FPC diet include 1) a lower Met content than typical rodent diets by decreasing total protein without supplementing sulfur amino acids; 2) choline supplementation is lower than typical but is not considered deficient; 3) high in sucrose (~34% by weight); 4) 1.25% cholesterol; 5) 52% kcal from fat with fat sources including milkfat fat, palmitic acid and hydrogenated vegetable shortening to provide trans-fats. Like the ALIOS model, the FPC model also provides a glucose/fructose solution to the drinking water.

Examples:

TD.160785?? ??52 kcal/Fat Diet (C16:0, HVO, AMF, Choline/Met)

Research use:

Male C57BL/6J mice fed the FPC diet and provided a glucose/fructose drinking solution developed insulin resistance and NAFLD with inflammation, hepatocyte death, and fibrosis within 16 weeks.

High fat diets

Common diets to induce obesity (DIO) can be fed to induce uncomplicated NAFLD. These high fat diets typically contain 40–60% kcal from fat without supplemented cholesterol or cholate. Simple sugars such as sucrose or fructose can also be supplemented via diet or water to progress the fatty liver phenotype. Diets can be in pellet or powder/dough form depending on the formula. Some models require limited physical activity and in those cases diets can be fed inside the cage. For more information see our?Diet Induced Obesity?page.

Examples:

TD.08811?? ? ??45%kcal Fat Diet (21% MF, 2% SBO)
TD.06414?? ? ??Adjusted Calories Diet (60/Fat)

Research use:

In susceptible rodent models, high fat diets are commonly used to induce NAFLD with obesity and insulin resistance common metabolic features associated with NASH in humans. However, the degree of NASH pathology (steatosis, inflammation, and fibrosis) is limited or mild and varies depending on the animal model, length of feeding, and dietary components.

COLLAPSE ALL TABS

Atherogenic diets high in fat, cholesterol, and cholate

Originally formulated to induce mild atherosclerosis in wild-type rodents, high fat diets containing added cholesterol (1 – 1.25%) and cholate (0.5% as sodium cholate or cholic acid) have also been useful in inducing NASH. This diet option includes purified “Western” style diets with increased cholesterol and cholate and also hybrid diets. Hybrid diets were originally developed by Beverly Paigen and colleagues by mixing a natural ingredient mouse diet in a 3:1 ratio with a concentrated purified diet (containing 5% cholesterol and 2% sodium cholate) resulting in a diet containing ~15.8% fat, 1.25% cholesterol, and 0.5% sodium cholate. Although a less refined approach, the hybrid diet is associated with increased gallstone formation and liver damage as compared to similar purified diets.

Examples:

TD.02028?? ? ??Atherogenic Rodent Diet
TD.88051?? ? ??Cocoa Butter Diet and Purina Mouse Chow
TD.09237?? ? ??15% AMF Diet (1% Chol, 0.5% NaChol)

Research use:

Atherogenic diets are able to induce varied degrees of NASH with increased hepatic inflammation with early fibrosis observed after ten weeks of feeding. However, the metabolic profile typical in human NASH (obesity with insulin resistance) is not recapitulated in this model with animals typically maintaining similar body weights as control fed groups without the development of metabolic syndrome.

Methionine/choline deficient (MCD) diets

Methionine and choline deficient (MCD) diets are amino acid defined rodent diets deficient in methionine and choline, high in sucrose (>40% by weight) with ~10% corn oil by weight. Methionine and choline deficiency decreases fat oxidation and export of fat from the liver. Dietary sucrose is necessary for hepatic lipid accumulation and oxidation. The polyunsaturated fat in corn oil promotes hepatic lipid oxidation.

Example:

TD.90262?? ? ??Methionine/Choline Deficient Diet

Control:

TD.94149?? ? ??Amino Acid Control Diet

Research use:

Steatosis, increased serum alanine aminotransferase (ALT), inflammation, and hepatic fat oxidation has been observed within three weeks of feeding the MCD diet with fibrosis development after six weeks. This dietary model does not produce metabolic syndrome (an aspect of NASH in human models) and progressive weight loss (up to 40%) is associated with the MCD diet feeding.

Emerging NASH models

Dietary models of NAFLD/NASH continue to evolve with the goal of more accurately recapitulating both the metabolic and hepatic symptoms of human disease. Commonly researchers are studying the synergistic effects of various NASH dietary features to accelerate progression of the model and severity of liver disease.

A Teklad nutritionist can work with you to formulate new diets in order to investigate novel dietary models of NAFLD/NASH.

Control diets

The choice of control diet is dependent on the specific research goal. Many researchers choose to compare their NAFLD/NASH diet-fed animals to animals fed a natural ingredient, grain-based diet (also referred to as standard diet or chow). These diets differ in the source and level of nutrients as well as in the presence of non-nutritive factors (such as phytates or phytoestrogens).

Depending on what your main comparisons are, it may be suitable to have a grain-based diet as your control/reference group. However, making such comparisons limits inferences to dietary patterns versus a specific dietary component. In some cases, such as those studies feeding amino acid defined diets like the MCD model, a matched control diet is recommended given the very different formulations and protein sources of grain-based diets.

When making inferences about specific nutrients within the diet an ingredient matched, low fat control diet may be necessary. There are many options with different levels and types of fat in addition to different types of carbohydrate ranging from sucrose (highly refined and digestible) to corn starch (refined, but more complex) to resistant starch (refined, but not fully digestible).

A very basic purified control diet would be AIN-93M?TD.94048?or AIN-93G?TD.94045. AIN-93 diets have a moderate amount of sucrose at ~10% with fat from soybean oil providing a healthy fatty acid profile.

Ether extract is used to measure fat in pelleted diets, while an acid hydrolysis method is required to recover fat in extruded diets. Compared to ether extract, the fat value for acid hydrolysis will be approximately 1% point higher.

Carbohydrate (available) is calculated by subtracting neutral detergent fiber from total carbohydrates.

Neutral detergent fiber is an estimate of insoluble fiber, including cellulose, hemicellulose, and lignin. Crude fiber methodology underestimates total fiber.

Energy density is a calculated estimate of metabolizable energybased on the Atwater factors assigning 4 kcal/g to protein, 9 kcal/g to fat, and 4 kcal/g to available carbohydrate.

Indicates added amount but does not account for contribution from other ingredients.

1 IU vitamin A = 0.3 μg retinol

1 IU vitamin D = 25 ng cholecalciferol

For nutrients not listed, insufficient data is available to quantify.

Nutrient data represent the best information available, calculated from published values and direct analytical testing of raw materials and finished product. Nutrient values may vary due to the natural variations in the ingredients, analysis, and effects of processing.

Harlan 嚙齒類飼料 Rodent diets

As a researcher, you want to have as much control as possible over what goes into your study animals. At Envigo, we understand that. That is why we developed?Teklad Global Rodent Diets?.

Teklad Global Rodent Diets??are a special integrated range of vegetarian laboratory rodent diets developed to be nutritionally complete for various life stages from breeding through long-term maintenance. Global rodent laboratory diets contain levels of protein, energy, vitamins and minerals that are more appropriate to the needs of modern biomedical research studies.

Furthermore, in global rodent diets particular attention has been placed on avoiding, as far as practical, ingredients that are reported to have adverse confounding effects on experimental results. This has resulted in a range of Teklad rodent laboratory diets that contain:

No fish meal

No meat meals or meat by-products

No alfalfa meal

No soybean meal or reduced levels

No animal fat

By excluding animal by-products, the presence of nitrosamines (a potential carcinogen) is avoided. Exclusion of alfalfa meal reduces chlorophyll, improving optical imaging clarity. Reduction or removal of soybean meal, together with elimination of alfalfa meal, minimizes levels of naturally-occurring phytoestrogens. Phytoestrogens interact with endogenous estrogens and potentially can affect studies in many?research areas. Read more about this in these pieces:

Benefits of global rodent diets

Traditional rodent diets were formulated decades ago based on understanding of rodent nutrition, ingredients, and diet manufacturing at the time. While traditional diets will supply the known nutrient needs of your laboratory animals, we recommend you consider the use of a diet from our newer global diet line for your modern research needs.

Teklad Global Rodent Diets^??are modern formulas designed to reduce research variables. Specifically, these diets contain more appropriate nutrient levels, and limit or exclude ingredients that are reported to have effects on a wide variety of research endpoints.

Lower, more appropriate protein levels can improve survival and reduce morbidity
Vegetarian with no nitrosamines (a potential carcinogen)
Formulated to exclude alfalfa meal, greatly improving fluorescent imaging clarity
Formulated to exclude or lower soybean meal, thus minimizing the presence of isoflavones, the primary type of phytoestrogen found in lab animal diets
Extruded rodent diets dramatically reduce clumping and hardness after autoclaving (2018SX,?2019S,?2020SX), and in general result in less diet waste and cleaner cages

Formulation

Teklad rodent diets are natural-ingredient diets specifically formulated to provide the proper balance of all known nutrients considered essential for the growth, maintenance, and reproduction of rats, mice, gerbils and hamsters. These diets conform to the nutrient requirements for rodents established by the National Research Council (1995).

Teklad rodent diets provide uniform nutrition. They are fixed-formula diets designed to minimize the nutrient variances which otherwise could occur if the ingredient composition of a diet were altered from one batch to the next.

Protein is supplied primarily by plant sources. Supplemental amino acids are added to provide the proper amount and balance of essential amino acids. All rodent diets are fortified with vitamins and minerals to help support the regulation of body fluids and the proper functioning of body systems to ensure the adequate growth, maintenance, and reproduction of research rodents. Autoclavable diets are supplemented with additional vitamins to compensate for losses that occur during autoclaving. Since our diets are nutritionally complete and balanced, it is not necessary to add dietary supplements.

Shelf life and storage

There is no definitive point where one is able to predict when a specific diet will spoil or become deficient in one or more nutrients. The common guideline of a six month shelf life is based on longstanding practice in North America. In Europe and Asia, differences in local practices and regulatory oversight have led to Teklad standard natural ingredient diets being routinely used out to nine months and sometimes 12 months post-manufacture. This practical experience, along with literature support and vitamin testing over time, gives us confidence that these diets continue to support animal health and study integrity out to at least nine months post-manufacture. Please refer to your institution for guidance if you are unsure of local policies.

Recommended storage conditions:

Cool and dry; at or below 70 degrees fahrenheit with humidity ideally below 50%, but up to 65% is acceptable
Clean and free of pests
In original packaging or in a container that prevents continuous exposure to light and minimal exposure to air

Feeding directions

Standard natural ingredient rodent diets are complete diets for rats, mice, gerbils and hamsters, that should be allowed?ad libitum?access to the diet. Fresh water should be available at all times.

Key points from the literature

TD.88137 has been used to accelerate atherosclerosis development in Apoe?and Ldlr?deficient models:

++In?Apoe?deficient mice, plasma cholesterol triples?to >1500 mg/dL within three weeks (1, 2). Foam cell and lesion development occurs within 6-10 weeks (2-4). Fibrous plaque formation is observed at 15 weeks with the development of fibrous caps after 20 weeks (2).

++Ldlr?deficient mice fed for two weeks increase?plasma cholesterol to >800 mg/dL and triglyceride to >300 mg/dL (5). After six weeks of feeding, hyperglycemia, hyperinsulinemia and dyslipidemia develop with small foam cell lesions in the aortic arch (6, 7).

Key planning information:

Store diet refrigerated and plan to use within six months. Diet should be replaced at minimum once per week when fed on cage tops.
Diets available as a soft ?” pellet or as a crumbly powder.
Three kg minimum order quantity. For planning purposes, estimates for diet uses (including feed intake and diet waste) are 5 g of diet per mouse and 30 g of diet per rat per day.
Two-day lead time for orders less than 10 kg. Two-week lead time for larger quantity orders.
Lead time for irradiation adds two weeks for any quantity of diet and must be requested at the time you place your order. Changes in texture and browning may occur with irradiation.
Shipping can affect pellet quality. Vacuum packaging can offer protection of the pellets during shipping. Two-day shipping is recommended during warmer months.
