Sweet potatoes are a nutrient-dense root vegetable, naturally sweet and high in fibre. They are a rich source of beta carotene (vitamin A), on average one medium sweet potato provides more than 100% of the Recommended Dietary Intake (RDI) for vitamin C. Also high in vitamin E and potassium. Store in a cool place but not in the fridge.

When purchasing seafood opt for wild caught fish, not farmed. Salmon is one of the best choices as it contains good amounts of omega 3 fatty acids. When purchasing canned fish, look for “pole and line caught” on the label.

Other names for spring onion are scallion or green onion. They have hollow green leaves and a small root bulb and can be eaten raw or cooked. The green tops are also used sliced or chopped as a garnish. The green tops are a good source of vitamin C and beta carotene.

Coriander is also know as cilantro. The fresh chopped green leaves in large amounts are a good source of vitamin C. The fresh leaves are an ingredient in many Indian, Thai, and Mexican dishes. They are usually tossed through just before serving as the heat can diminish the flavour. The dried fruits are known as coriander seeds, the seeds have a lemony citrus flavour when crushed. The word coriander in food preparation may only be referring to the ground seeds not the plant.

Parsley would be the most widely used herb worldwide. The two main varieties of this herb are curly parsley with ruffled leaves and Italian parsley with flat leaves. In general flat-leaf parsley has a more robust flavour than the curly leave parsley. Its fresh green flavour and colour can be much more than just a garnish. Both kinds of parsley may be used in cooking. Fresh parsley contains useful amounts of vitamin C, calcium, iron and potassium. Parsley is also high in bioflavonoids and other anticancer compounds.

I have used large free range or organic eggs from a 700g carton in my recipes. Eggs are one of the few foods considered to be a complete protein because they contain all 9 essential amino acids, also studies have shown that lutein (yellow colour) in egg yolks protects against the progress of early heart disease.

The most favoured gluten/grain free flour substitute in my kitchen is almond meal. It is finely ground blanched almonds and is also known as almond flour. It has a slightly sweet flavour so you don’t have to add as much sweetener when baking with it. Almond meal/flour is rich in manganese which helps the body heal after injuries and also helps the body break down carbohydrates. Almond flour is also rich in magnesium, which can help control your blood sugar levels. It's rich in vitamin E and other antioxidants, which may help reduce the risk of serious health conditions like cancer, diabetes, stroke, and heart disease. Almonds are also a good source of calcium.

All kinds of nuts can be ground down to make a meal and are excellent for raw cheesecake or pie bases. Nut meals/flours are best stored in airtight containers in the fridge or freezer to prevent them going rancid.

An excellent soy free alternative to soy sauce and tamari. It comes from the sap of the coconut tree and has a sweeter flavour than soy sauce and is not as salty. Coconut aminos can be purchased from health food stores or online. This is one of my favourite ingredients.

Just a little of this sauce will make a big difference to a recipe. Fish sauce is used in Asian cooking, be adventurous and add to other types of dishes to enhance the flavour. Read your label when purchasing as you just want fish and salt, no preservatives or sugar added.

Cumin is a medium - hot spice which blends well in curries and is the main spice in the Middle Eastern dip, hummus. It is being studied for potential anti-oxidant and anticancer effects.

Raw pink Himalayan salt crystals is unlike common table salt which can be a highly refined industrial byproduct, otherwise know as sodium chloride. Himalayan salt is completely pure and may naturally balance the body's alkaline/acidity and regulate water content. In addition Himalayan salt helps in the absorption of nutrients from food and contains many trace minerals for healthy cell structure. I purchase fine pink Himalayan crystal salt so I can use it in my shaker and for cooking.

Black and white pepper both come from the fruit of a tropical vine. Black pepper is the cooked and dried unripe fruit, known as a peppercorn and white pepper is from the ripe fruit seed. Pepper is usually coupled with salt, sprinkled over or added to food.

Coconut oil is one of the most nutritious fats to cook and bake with. Use organic extra-virgin coconut oil which is unrefined and unbleached from non GMO coconuts. Coconut oil has a high smoking point and it is slow to oxidize due to its high saturated fat content, thus, resistant to going rancid. Some studies suggest coconut oil helps with digestion, including irritable bowel, tummy bugs, candida and parasites due to this oil containing short term medium-chain saturated fatty acids (MCFAs), which is a healthy form of saturated fat.

Arrowroot is a herb, the roots are cultivated for its starch properties. It is used in my recipes as a thickener and I also like combining it with almond meal to produce a much lighter texture, more like a gluten flour. I find the starch helps to bind the ingredients together. You can substitute tapioca flour, which is made from the dried roots of the cassava plant. Tapioca can be used in baking, it has a slightly sweet flavour. However, I do not recommend thickening with tapioca, as it has a stretchy, gummy texture. Supermarkets only sell in very small containers, which is not cost effective. Purchase from baking specialty stores, health food stores or online. ( When substituting for cornflour in recipes, 2 teaspoons arrowroot = 1 tablespoon cornflour/starch).
