矿物调整饮食

一些矿物调整公式如下所示。请与我们联系，以获得更多的这种性质的配方，或更多的信息，改变矿物质的饮食。有关更多信息，请阅读下面。

公式示例：

独特的蛋白质成分可能是必要的，以尽量减少某些矿物质的背景水平。为尽量减少背景矿物污染而采取的其他步骤包括在必要时使用试剂级矿物或遗漏某些成分。在这些饮食中可以使用特殊的矿物预混料，也可以在饮食中单独添加矿物质，以控制特定矿物质的含量。

除钠外，必须使用精制成分，以达到饮食中矿物质含量尽可能低的水平。

从这种矿物缺乏的基础，不同水平的矿物可以补充回来。一些配方调整多种矿物质和其他相关营养素。

联系我们讨论上述矿物和未列出的矿物的其他可能性。

Mineral adjusted diets | Envigo

A few mineral adjusted formulas are shown below. Please contact us for additional formulas of this nature or for more information about altering the mineral profile of a diet. Read below for more information.

Formula examples:

  • TD.80396      Iron deficient diet
  • TD.85419      Zinc deficient diet
  • TD.88239      Potassium deficient diet
  • TD.95027      Low calcium diet (0.4% P)
  • TD.96348      Diet (20% lactose, 2% Ca, 1.25% P)
  • TD.92163      Selenium deficient diet
  • TD.95125      Iodine deficient (0.15% PTU)

Unique protein ingredients may be necessary to minimize background levels of certain minerals. Other steps taken to minimize background mineral contamination include the use of reagent grade minerals when necessary or omission of certain ingredients. Specialized mineral premixes may be used in these diets, or minerals are added individually to the diet in order to control the level of specific minerals.

With the exception of sodium, it is necessary to use refined ingredients to achieve the lowest possible levels of minerals in a diet.

From this mineral deficient base, various levels of minerals can be added back. Some formulas adjust multiple minerals, and other related nutrients.

Contact us to discuss other possibilities for the minerals listed above, and for those minerals not listed here.

贝弗利·派根和他的同事首先通过喂养一种混合性动脉粥样硬化饮食来描述C57BL/6小鼠动脉粥样硬化的发展。这种混合饲料是通过将一种天然成分的老鼠饲料按3：1的比例与浓缩的纯化饲料(含5%胆固醇和2%胆酸钠；称为Thoms-Hartroft饮食)混合而成的。产生的混合物在TD.88051/TD.90221(同配方)含有~15.8%脂肪、1.25%胆固醇和0.5%胆酸钠。这组人后来将混合动脉粥样硬化饮食方法与更现代的“西方”纯化动脉粥样硬化饮食方法进行了比较，并添加了胆固醇和胆酸盐，发现混合动脉粥样硬化饮食会导致更多的胆结石和肝脏损伤。混合饮食含有多种未精制的成分，这些成分可能会改变血脂代谢和动脉粥样硬化的发生，并且不允许对成分和营养物进行精确控制，以用于慢性病的研究。虽然已经开发出了更精细的饮食，但混合动脉粥样硬化饮食仍然是野生型小鼠和大鼠诱发轻度动脉粥样硬化和胆结石的流行食品。联系我们获得更多的信息，修改，或可能的控制饮食。

Atherogenic

Diet can be a useful tool to induce or accelerate atherosclerosis in laboratory animal models.Key dietary features used to induce atherosclerosis in rodents vary depending on the research model, desired endpoint, and length of feeding.While formulations of atherogenic diets continue to evolve, the options that are well-described in the literature are summarized below.For more information on each diet option and literature references see the expandable tabs following the diet table.

Research use Key dietary features Examples
“Western” purified atherogenic diet
Accelerated hypercholesterolemia and plaque formation in genetically modified models such as Apoe and Ldlr deficient mice.

Used for diet induced obesity in a variety of rodent models.

Will not promote obesity.
  • High fat diet (15 – 20% by weight; 34 – 45% kcal from fat)
  • Saturated fatty acids (SFA >55% of total fatty acids)
  • Milkfat/butterfat, cocoa butter
  • Sucrose (30-50% by weight)

  • Standard, grain-based rodent diet
  • Minimal/moderate phytoestrogen diets recommended
  • Cholesterol (1 – 4%)
 TD.120097
TD.07841
TD.01383

*Sodium cholate or cholic acid aid cholesterol and fat absorption and reduce cholesterol disposal via bile acid synthesis. However, if including a cholate source is not desired for your research, diets without cholate are available.

COLLAPSE ALL TABS

“Western” style diets are fed to genetically-modified cardiovascular models, such as Apoe and Ldlr deficient mice, to accelerate and enhance hypercholesterolemia and plaque formation and to elicit phenotypes commonly associated with metabolic syndrome. Within the atherogenic literature, a “Western” diet typically is described as a purified rodent diet with 20-23% milkfat/butterfat, 0.2% total cholesterol, and 34% sucrose by weight. TD.88137 is an example of a “Western” style diet that was originally designed to characterize and enhance atherosclerosis development in a newly generated Apoe-deficient mouse model. Contact us for more information about “Western” style diets, modifications, or possible control diets.

Examples:

  • TD.88137    Adjusted calories diet (42% from fat, 0.2% total cholesterol)
  • TD.10885    45% fat Kcal diet (0.2% total cholesterol)

Research use:

Accelerated hypercholesterolemia and plaque formation in genetically-modified models, such as Apoe and Ldlr deficient mice.

Used for diet-induced obesity in a variety of rodent models.

Key dietary features:

  • High Fat Diet (20-23% by weight; 40 – 45% kcal from fat)
  • Saturated fatty acids (SFA >60% of total fatty acids)
  • Milkfat/butterfat
  • Sucrose (34% by weight)
  • Cholesterol (0.2% total)

Wild type mice and rats generally are resistant to atherosclerosis, requiring more extreme dietary manipulation to modify lipoprotein profiles and develop mild atherosclerosis (foam cells, fatty streaks). Modern formulations are made completely of purified ingredients because this more refined approach has been reported to decrease the incidence of gallstones and liver damage associated with less refined and more traditional dietary approaches. To induce mild atherosclerosis in wild type animals, the “Western” purified diet can be modified to increase cholesterol (1-1.25%) and add a bile salt such as sodium cholate or cholic acid. Contact us for more information, modifications, or possible control diets.

Examples of purified high fat diets with added cholesterol and cholate source*:

  • TD.02028    21% milkfat (1.25% cholesterol, 0.5% cholic acid)
  • TD.09237    15% milkfat diet (1% cholesterol, 0.5% sodium cholate)

Examples of purified high fat diets with added cholesterol (without cholate source):

  • TD.96121    21% milkfat (1.25% cholesterol)

Research Use:

Induce hypercholesterolemia and mild atherosclerosis (foam cells, fatty streaks) primarily in wild type mice and rats.

Will not promote obesity.

Key dietary features:

  • High fat diet (15-20% by weight; 34 – 45% kcal from fat)
  • Saturated fatty acids (SFA >55% of total fatty acids)
  • Milkfat/butterfat, cocoa butter
  • Sucrose (30-50% by weight)
  • Cholesterol (1 – 1.25%)
  • Cholate source (0.5%)*

Beverly Paigen and colleagues first characterized atherosclerosis development in C57BL/6 mice by feeding a hybrid atherogenic diet. The hybrid diet was created by mixing a natural ingredient mouse diet in a 3:1 ratio with a concentrated purified diet (containing 5% cholesterol and 2% sodium cholate; referred to as Thomas-Hartroft diet). The resulting mixture recreated in TD.88051/TD.90221 (same formula) contains ~15.8% fat, 1.25% cholesterol, and 0.5% sodium cholate. This group later compared the hybrid atherogenic diet approach to the more modern “western” purified atherogenic diet with added cholesterol and cholate and found that the hybrid atherogenic diet induced more gallstones and liver damage. Hybrid diets contain a variety of unrefined ingredients that may modify lipid metabolism and atherogenesis and do not allow for precise control of ingredients and nutrients for the study of chronic diseases. Although more refined diets have been developed, hybrid atherogenic diets are still popular for inducing mild atherosclerosis and gallstones in wild type mice and rats. Contact us for more information, modifications, or possible control diets.

Examples of hybrid high-fat diets with added cholesterol and cholate source*:

  • TD.88051 and TD.90221 (same formula) are Teklad product codes for hybrid atherogenic diets

Example of hybrid high-fat diet with added cholesterol (without cholate source):

  • TD.94059

Research Use:

Induce hypercholesterolemia and mild atherosclerosis (foam cells, fatty streaks) primarily in wild type mice and rats.

Will not promote obesity.

Also used for lithogenic (gallstone) rodent studies.

Key dietary features:

  • 75% rodent breeder diet; 25% purified ingredients
  • High fat (~15% by weight; 37% kcal from fat)
  • Saturated fatty acids (SFA >45% of total fatty acids)
  • Cholesterol (1.25%)
  • Cholate source (0.5%)*

Standard, natural ingredient diets with cholesterol added are fed to induce hypercholesterolemia. Various levels of cholesterol, fat, and/or bile salts can be added to one of the numerous standard rodent diets stocked by Envigo Teklad. For many applications, adding these components to Envigo’s minimal-to-moderate phytoestrogen global rodent diets is recommended. Our minimal phytoestrogen global rodent diets are soybean meal free, limiting the effect of phytoestrogens on your research outcomes. Soybean meal, a common dietary source of phytoestrogens, has been shown to decrease aortic fatty streak development and modify plasma cholesterol, which may reduce the risk of developing atherosclerosis. Limiting dietary soybean meal may reduce confounding variables within your dietary-induced atherosclerosis model. Contact a nutritionist to discuss additional diet options.

Examples of minimal and moderate phytoestrogen rodent diets with added cholesterol:

  • TD.120097  1% cholesterol diet (2020 – minimal phytoestrogens)
  • TD.07841    2% cholesterol diet (2016 – minimal phytoestrogens)
  • TD.01383    2% cholesterol (2018 – Moderate phytoestrogens)

Research use:

Induce hypercholesterolemia in genetically-modified and wild type models without promoting obesity.

Key dietary features:

  • Standard, grain-based rodent diet
  • Minimal/moderate phytoestrogen diets recommended
  • Cholesterol (1 – 4%)

维生素调整饮食

一些维生素调整公式如下所示。请与我们联系，以获得更多的这种性质的配方或更多的信息，以改变维生素的饮食概况，并请阅读下面来了解更多。

公式示例：

大多数缺乏维生素的饮食使用无维生素的测试酪蛋白(VFT酪蛋白)作为蛋白质来源。VFT酪蛋白是用变性醇提取的酪蛋白，使脂肪含量从1%左右降至0.1%左右。在这个过程中，一些维生素的含量(在低水平或微量的酪蛋白)被进一步减少，使之成为这些类型的饮食的理想的蛋白质来源。Envigo生产我们自己的VFT内部产品，我们也为那些混合他们自己的饮食的人提供这种材料。

从这个缺乏维生素的基础，不同水平的维生素可以补充回来。许多配方调整多种维生素和其他营养。

如果使用完整的蛋白质源是不可取的，氨基酸限定饮食可以使用。

Vitamin adjusted diets | Envigo

A few vitamin adjusted formulas are shown below. Please contact us for additional formulas of this nature or for more information about altering the vitamin profile of a diet, and please read below to learn more.

Formula Examples:

  • TD.86143      Vitamin A deficient diet
  • TD.89123      Vitamin D deficient diet
  • TD.88163      Vitamin E deficient diet
  • TD.95247      Folic acid deficient diet

Most vitamin deficient diets use vitamin-free test casein (VFT casein) as the protein source. VFT casein is casein that has been extracted with denatured alcohol to reduce the fat content from about 1% to 0.1%. In the process the content of a number of vitamins (present at low or trace levels in casein) is further reduced, making this an ideal protein source for these types of diets. Envigo produces our own VFT in-house, and we also offer this as an ingredient for those mixing their own diets.

From this vitamin deficient base, various levels of vitamins can be added back. Many formulas adjust multiple vitamins, and other nutrients.

If use of an intact protein source is not advisable, an amino acid defined diet can be used.
