Maple Syrup

Many terrific things come from Canada, not least of which are ice hockey, Justin Beiber and – our personal favourite, Celine Dion. Arguably though, maple syrup sits at the top of the list.

Made from the sap of a number of varieties of maple tree native to Canada and the United States, maple syrup is a good source of calcium, potassium, iron, zinc and manganese[20], with one study identifying over twenty-four separate anti-oxidants[21].

Milk Protein

Milk protein isolate is a protein rich product derived from milk that is rich in caseinate and whey proteins in very similar ratios to milk; 80% caseinate, 20% whey[22]. Milk protein isolate also contains all nine essential amino acids[23] and is a great source of leucine, one of the nine essential amino acids that supports muscle protein synthesis[24] [25].

Casinate proteins are slower to digest than whey proteins, the result being the amino acids contained in caseinate are released at a slow sustained rate[26], with one study suggesting this steady supply of amino acids may help to maintain and muscle mass after exercise and during sleep[27].

In addition to supporting muscle recovery, milk protein isolate may also play a role in improved bone strength[28] [29].

Good ol’ milk protein isolate, we say.

Milk, Dark & White Protein Chocolate

Who says something great tasting can’t be good for us too? Our three delicious chocolate toppings contain twenty-five percent whey protein concentrate[30].

Wholegrain Jumbo & Porridge Oats

DuelFuel only uses both jumbo and porridge wholegrain oats, to give DuelFuel’s flapjack range that terrific texture and eating experience.

The only difference between jumbo and porridge oats is the size to which they have been milled. Porridge oats are milled for longer and are therefore smaller than jumbo oats.

Irrespective of their size, all DuelFuel’s oats are whole grain, which consist of three main parts[31] [32]

  • Bran:

    The hard outer layer of the grain, which contains fibre, minerals and antioxidants
  • Germ:

    The nutrient-rich core that contains carbohydrates, fats, proteins, vitamins, minerals, antioxidants and various phytonutrients. The germ is the part that gives rise to a new plant
  • Endosperm:

    The biggest part of the grain, contains mostly carbohydrates in the form of starch and protein

A refined grain has had the bran and germ removed, leaving just the endosperm[33] and tend to be of less nutritional benefit, whereas whole grains are high in fibre, vitamins B1, B2 & B3, magnesium, iron, phosphorus, manganese and selenium (5, 6). We put the whole of the oat into our flapjacks, to derive the most nutritional benefit.

Peanuts & Peanut Butter

Did you know a peanut isn’t a nut? No Bro, neither did we until we looked it up, but peanuts are classified as legumes; along with foods like green peas, soybeans and lentils and grow below the ground of the peanut plant.

Peanuts are pocket-rockets of fat, protein and fibre[34]. The fat is unsaturated, which is widely thought to be a heart-friendly fat[35] and some studies suggest that when eaten in small amounts daily, peanuts can reduce the risk of many chronic diseases.[36]

We love peanuts because they are a good source of biotin[37] [38] (link to Biotin in vitamins and minerals), copper[39] (link to copper in vitamins and minerals) , Vitamin B3 (Niacin)[40] link to B3 in V&M section), folate, manganese, Vitamin E, thiamine, phosphorous and magnesium (all hyperlinked to their respective sections in the duelfuel V&M section)

Pecans

In a nutritional throwdown pecans can go toe-to-toe against the mighty peanut and have the added advantage that they are in fact…nuts and not nut wannabes. They are also a nutrition powerhouse, packing a 1-2-3 punch of protein, healthy fats - one study suggests they contribute to a reduction in the risk of heart disease[41] and fibre.

They also come fully loaded with a host of vitamins and minerals including copper, Vitamin B1, zinc, magnesium, phosphorous and iron.[42] (hyperlink each V&M back to its section in DuelFuel V&M section)

Raspberries

The little ol’ raspberry holds its own against the swagger of the blueberry and is a source of Vitamin A, vitamin C, thiamine, riboflavin, vitamin B6, calcium and zinc [43] and can also boast anti-inflammatory and antioxidative properties.

Vitamins & Minerals Blend

All our flapjacks, brownies and cake slices contain exactly the same twenty-seven vitamins and minerals blend; the combination of which supports the body during and after exercise. Here’s what each of the twenty-seven vits and mins team contribute to:
