Lamb Based Diets A Closer Look at Acana s Approach to Canine Nutrition

ACANA FAQs FOR PET LOVERS

Q. How do I transition my pet to ACANA foods?

Dogs and cats are often fed the same food for a long period of time, which means a sudden food change makes it difficult for their digestive systems to adapt. Thats why its important to introduce new food gradually. Going slowly will give your dog or cat time to adjust to their new food and will also reduce the chances of digestive upset. Start by mixing 25 percent new food with 75 percent old food. Slowly increase the new food proportionately over the next 5-7 days until you are feeding 100 percent new food.

Q. Which ACANA diet should i choose?

The first time you transition your dog or cat to ACANA, we recommend selecting a recipe with an animal ingredient that matches the food you are currently feeding. This will help allow for the easiest transition and help minimize the risk of gastrointestinal upset. For example, if your dog is currently on a poultry-based diet, you may want to try the ACANA Prairie Poultry or Wild Prairie.It is also important to consider the life stage of your pet. With foods for puppies, kittens, adults, seniors and All Life Stages youre sure to find the right fit. A FEDIAF statement indicating which nutrient profile the food is formulated to meet can be found on our website under the Ingredients & Analysis tab of each respective diet.For more specific dietary needs, please contact our Customer Care department.

Q. What is a rotational diet? Can Ido this with ACANA?

After initially transitioning to ACANA, what many Pet Lovers do is a method of feeding known as Rotational Feeding. Rotating between ACANA formulas prevents your dog or cat from getting tired of eating the same thing day in and day out, while offering them a great variety of proteins and fats. A good place to start is rotating by the bag when you have finished one formula, your next bag will be a different recipe. The first time you introduce a new food for rotation, mix the food 50/50 just to make sure your pet transitions well to the new ACANA food. However, if your dog or cat is more diet-sensitive, do a full transition when introducing a new ACANA food after that you can change at will.Rotational Feeding.pdf

Q. Do you have any feeding tips?

Feed according to your dog or cats size, breed, stage of life and activity level. Consider that puppies and kittens require up to twice the energy of full-grown pets, and that overweight and senior pets often need smaller meals just like people!We recommend that for most pets, you feed twice daily. Simply divide the amount suggested on the feeding guide into two meals, spaced eight to 12 hours apart. For example, if the feeding guide calls for 1 cup per day, we recommend feeding a cup in the morning and a cup at night. You may need to adjust portions as you learn your pets ideal daily maintenance amount. These amounts may change over time as your pets age and activity levels change. Always keep in mind that a lean dog or cat is a healthy pet.Many dogs and cats have large appetites and will eat everything you feed them. As ACANA foods are highly palatable, you need to be careful not to overfeed, as this can cause issues such as loose stool or unwanted weight gain.

Q. How many treats should i feed?

We all love to give our pets treats. However, treats should be given in moderation and should represent 10% or less of your pets daily food intake. The rest should come from a nutritionally complete feeding program. When using treats frequently, such as during training exercises, try to use small pieces.Feeding Treats.pdf

Lamb 101: Nutrition Facts and Health Effects

Not only is it a rich source of high-quality protein, but lamb is also an outstanding source of iron, zinc, and vitamin B12. Regular consumption may promote muscle growth, maintenance, and performance. In addition, it helps prevent anemia.

Lamb is the meat of young domestic sheep (Ovis aries).

Its a type of red meat a term used for the meat of mammals that is richer in iron than chicken or fish.

The meat of young sheep in their first year is known as lamb, whereas mutton is a term used for the meat of adult sheep.

Its most often eaten unprocessed, but cured (smoked and salted) lamb is also common in some parts of the world.

Being rich in high-quality protein and many vitamins and minerals, lamb can be an excellent component of a healthy diet.

Heres everything you need to know about lamb.

Lamb is mainly composed of protein but also contains varying amounts of fat.

A 3.5-ounce (100-gram) serving of roasted lamb provides the following nutrients (1):

• Calories: 258
• Water: 57%
• Protein: 25.6 grams
• Carbs: 0 grams
• Sugar: 0 grams
• Fiber: 0 grams
• Fat: 16.5 grams

Protein

Like other types of meat, lamb is primarily composed of protein.

The protein content of lean, cooked lamb is usually 2526% (1).

Lamb meat is a high-quality protein source, providing all nine essential amino acids your body needs for growth and maintenance.

Therefore, eating lamb or other types of meat may be especially beneficial for bodybuilders, recovering athletes, and people post-surgery.

Eating meat promotes optimal nutrition whenever muscle tissue needs to be built up or repaired.

Fat

Lamb contains varying amounts of fat depending on how much of it has been trimmed away, as well as the animals diet, age, gender, and feed. The fat content is usually around 1721% (1).

It is composed mainly of saturated and monounsaturated fats in approximately equal amounts but also has small amounts of polyunsaturated fat.

Thus, a 3.5-ounce (100-gram) serving of roasted lamb provides 6.9 grams of saturated, 7 grams of monounsaturated, and only 1.2 grams of polyunsaturated fat (1).

Lamb fat, or tallow, usually contains slightly higher levels of saturated fat than beef and pork (2).

Saturated fat has long been considered a risk factor for heart disease, but many studies have not found any link (3, 4, 5, 6, 7).

Lamb tallow also contains a family of trans fats known as ruminant trans fats.

Unlike trans fats found in processed food products, ruminant trans fats are believed to be beneficial for health.

The most common ruminant trans fat is conjugated linoleic acid (CLA) (8).

Compared to other ruminant meats such as beef and veal lamb contains the highest amounts of CLA (9).

CLA has been linked to various health benefits, including reduced body fat mass, but large amounts in supplements may have adverse effects on metabolic health (10, 11, 12).

SUMMARY

High-quality protein is the main nutritional component of lamb. It also contains varying amounts of fat mostly saturated fat but also small amounts of CLA, which has several health benefits.

Lamb is a rich source of many vitamins and minerals, including:

• Vitamin B12. Important for blood formation and brain function. Animal-derived foods are rich in this vitamin, whereas vegan diets lack it. Deficiency may cause anemia and neurological damage.
• Selenium. Meat is often a rich source of selenium, though this depends on the feed of the source animal. Selenium has various important functions in the body (13).
• Zinc. Zinc is usually much better absorbed from meat than plants. Its an essential mineral important for growth and the formation of hormones, such as insulin and testosterone.
• Niacin. Also called vitamin B3, niacin serves a variety of important functions in your body. Inadequate intake has been linked to an increased risk of heart disease (14).
• Phosphorus. Found in most foods, phosphorus is essential for body growth and maintenance.
• Iron. Lamb is rich in iron, mostly in the form of heme iron, which is highly bioavailable and absorbed more efficiently than non-heme iron found in plants (15).

In addition to these, lamb contains a number of other vitamins and minerals in lower amounts.

Sodium (salt) may be particularly high in some processed lamb products, such as cured lamb.

SUMMARY

Lamb is a rich source of many vitamins and minerals, including vitamin B12, iron, and zinc. These are important for various bodily functions.

Aside from vitamins and minerals, meat including lamb contains a number of bioactive nutrients and antioxidants that may affect health:

• Creatine. Creatine is essential as an energy source for muscles. Supplements are popular among bodybuilders and may be beneficial for muscle growth and maintenance (16, 17).
• Taurine. This is an antioxidant amino acid found in fish and meat but also formed in your body. Dietary taurine may be beneficial for your heart and muscles (18, 19, 20).
• Glutathione. This antioxidant is present in high amounts in meat. Grass-fed beef is particularly rich in glutathione (21, 22).
• Conjugated linoleic acid (CLA). This family of ruminant trans fats may have various beneficial health effects when consumed in normal amounts from food, such as lamb, beef, and dairy products (23, 24).
• Cholesterol. A sterol found in most animal-derived foods, dietary cholesterol does not have significant effects on cholesterol levels in most people (25).

SUMMARY

Lamb contains several bioactive substances such as creatine, CLA, and cholesterol that may benefit health in various ways.

As a rich source of vitamins, minerals, and high-quality proteins, lamb can be an excellent component of a healthy diet.

Muscle maintenance

Meat is one of the best dietary sources of high-quality protein.

In fact, it contains all nine amino acids you need and is referred to as a complete protein.

High-quality protein is very important for maintaining muscle mass especially in older adults.

Inadequate protein intake may accelerate and worsen age-related muscle wasting. This increases your risk of sarcopenia, an adverse condition associated with very low muscle mass (26).

In the context of a healthy lifestyle and adequate exercise, regular consumption of lamb or other high-protein foods may help preserve muscle mass.

Improved physical performance

Lamb not only helps preserve muscle mass but may also be important for muscle function.

It contains the amino acid beta-alanine, which your body uses to produce carnosine, a substance necessary for muscle function (27, 28).

Beta-alanine is found in high amounts in meat, such as lamb, beef, and pork.

High levels of carnosine in human muscles have been associated with decreased fatigue and improved exercise performance (29, 30, 31, 32).

Diets low in beta-alanine such as vegetarian and vegan diets may decrease levels of carnosine in your muscles over time (33).

On the other hand, taking high doses of beta-alanine supplements for 410 weeks has been shown to cause a 4080% increase in the amount of carnosine in muscles (27, 29, 34, 35).

Therefore, regular consumption of lamb or other foods rich in beta-alanine may benefit athletes and those who want to optimize their physical performance.

Anemia prevention

Anemia is a common condition, characterized by low levels of red blood cells and decreased oxygen-carrying capacity of your blood. The main symptoms include fatigue and weakness.

Iron deficiency is a major cause of anemia but can be easily avoided with proper dietary strategies.

Meat is one of the best dietary sources of iron. It not only contains heme-iron a highly bioavailable form of iron but also improves the absorption of non-heme iron, the form of iron found in plants (15, 36, 37).

This effect of meat is not entirely understood and is referred to as the meat factor (38).

Heme-iron is only found in animal-derived foods. Therefore, its often low in vegetarian diets and absent from vegan diets.

This explains why vegetarians are more at risk of anemia than meat-eaters (39).

Simply put, eating meat may be one of the best dietary strategies to prevent iron deficiency anemia.

SUMMARY

Lamb may promote the growth and maintenance of muscle mass and improve muscle function, stamina, and exercise performance. As a rich source of highly available iron, lamb may help prevent anemia.

Heart disease is a major cause of premature death.

Its a group of adverse conditions involving the heart and blood vessels, including heart attacks, strokes, and high blood pressure.

Observational studies have revealed mixed results on the link between red meat and heart disease.

Some studies find an increased risk from eating high amounts of both processed and unprocessed meat, whereas others note an increased risk for processed meat only or no effect at all (40, 41, 42, 43).

No hard evidence supports this link. Observational studies only reveal an association but cannot prove a direct causal relationship.

Several theories have been proposed to explain the association of high meat intake with heart disease.

For example, a high intake of meat may mean less intake of other beneficial foods, such as heart-healthy fish, fruit, and vegetables.

It is also linked to unhealthy lifestyle factors, such as lack of physical activity, smoking, and overeating (44, 45, 46).

Most observational studies try to correct for these factors.

The most popular theory is the diet-heart hypothesis. Many people believe that meat causes heart disease because it contains high amounts of cholesterol and saturated fat impairing the blood lipid profile.

However, most scientists now agree that dietary cholesterol is not a risk factor for heart disease (25).

Also, the role of saturated fats in developing heart disease is not entirely clear. Many studies have not been able to link saturated fat with an increased risk of heart disease (5, 6, 7).

In itself, meat doesnt have adverse effects on your blood lipid profile. Lean lamb has been shown to have similar effects as fish or white meat, such as chicken (47).

Still, you should avoid eating high amounts of cured lamb or meat cooked at high heat.

SUMMARY

Its debated whether eating lamb increases your risk of heart disease. Eating mildly cooked, lean lamb in moderation is probably safe and healthy.

Cancer is a disease characterized by abnormal cell growth. Its one of the worlds leading causes of death.

A number of observational studies show that people who eat a lot of red meat are at an increased risk of colon cancer over time (48, 49, 50).

Yet, not all studies support this (51, 52).

Several substances in red meat may increase cancer risk, including heterocyclic amines (53).

Heterocyclic amines are a class of cancer-causing substances formed when meat is exposed to very high temperatures, such as during frying, baking, or grilling (54, 55).

Theyre found in relatively high amounts in well done and overcooked meat.

Studies consistently indicate that eating overcooked meat or other dietary sources of heterocyclic amines may increase the risk of various cancers, including of the colon, breast, and prostate (56, 57, 58, 59, 60).

Though there is no clear-cut proof that meat intake causes cancer, it seems sensible to avoid eating high amounts of overcooked meat.

Moderate intake of mildly cooked meat is likely safe and healthy especially when its steamed or boiled.

SUMMARY

Eating a lot of red meat has been linked to increased cancer risk. This may be due to contaminants in meat particularly those that form when meat is overcooked.

Lamb is a type of red meat that comes from young sheep.

Not only is it a rich source of high-quality protein, but it is also an outstanding source of many vitamins and minerals, including iron, zinc, and vitamin B12.

Because of this, regular consumption of lamb may promote muscle growth, maintenance, and performance. In addition, it helps prevent anemia.

On the negative side, some observational studies have linked a high intake of red meat to an increased risk of cancer and heart disease.

Because of contaminants, high consumption of processed and/or overcooked meat is a cause for concern.

That said, moderate consumption of lean lamb that has been mildly cooked is likely both safe and healthy.
