Smoothies are one of those foods that have stayed popular and remained on the food trend list for the last few years. Everywhere you look; restaurants, recipe books, food blogs and Pinterest are filled with the most delicious smoothie recipes and a simple google search on smoothies can pull through pages and pages of articles and recipes, but needless to say, looking through all this information can be a pretty daunting task. For those of you who don’t know anything about smoothies…you are in luck, here is all the information you need to know about making a nutritious smoothie.
WHAT ARE THEY?
A smoothie is a blended drink made from a combination of fruits and/or vegetables; a liquid such as milk, a milk alternative, yogurt or juice and ice.1 Smoothies can vary in thickness depending on the ratio of solid to liquid ingredients used.
WHY ARE THEY A GREAT ADDITION TO YOUR DAY?
As smoothies contain a combination of foods, they are a great way to boost your nutrition in one meal. They often contain beneficial vitamins, minerals, antioxidants, fibre as well as healthy fats and protein. Smoothies are versatile and if made correctly they can be had as a meal, snack or healthy treat. There are endless combinations of ingredients that you can use to make smoothies, therefore it’s difficult to get bored. Smoothies are also quick and easy to prepare, just put all the ingredients into a blender and ‘whala’ you have a nutrient dense meal.
ARE SMOOTHIES SAFE FOR INDIVIDUALS LIVING WITH DIABETES?
Living with diabetes doesn’t mean you need to deny yourself all the foods you love, but it is still important to ensure that you make healthier food choices. As smoothies contain many ingredients, they can often be high in sugar, carbohydrates and calories which can cause havoc on blood sugar levels. Therefore it’s important to choose your ingredients carefully and keep an eye on how much you drink at a time.
HOW TO MAKE A ‘DIABETIC-FRIENDLY’ SMOOTHIE
- CHOOSE YOUR PRODUCE
Most smoothie recipes call for the addition of a selection of fruits. Fruits are high in vitamins, minerals, fibre, antioxidants and natural sugars. Any seasonal fruit of your choice can be used but make sure include fruits of different colours. Examples include all berries, apples, pear, melon, nectarine, citrus, kiwi and plums etc. Watch your portion of the following fruit as they contain more sugar per portion e.g. banana’s, grapes, figs, paw paw, melon and dried fruit.
If you are going to include other carbohydrate sources in your smoothie, such as dairy or a cereal product e.g. FUTURELIFE® or oats, it is suggested you only include 1/2 – 1 fruit portion per smoothie.
One fruit portion = 1 tennis ball size fruit OR 2 golf ball size fruit OR ½ cup
People often forget about adding vegetables to smoothies. Vegetables also contain fewer carbohydrates than fruit therefore are helpful in keeping the total carbohydrate of the smoothie down. Including vegetables in your smoothie is a quick and convenient way to include more vegetables into your day. Any of the green vegetables such as kale, spinach, broccoli, cucumber and avocado are great additions to any smoothie as they contain little carbohydrates. Be careful of starchy vegetables such as carrots or beetroot. Some recipes also call for cooked vegetables like sweet potato or legumes that contribute to fibre content, texture and taste.
One vegetable portion = 1 cup raw vegetables OR ½ cup cooked
Natural sugars, found in fruits and starchy vegetables, also cause spikes in your blood sugar levels if too much is eaten at once. Remember to count the fruit and starchy vegetables you blend into your smoothies as part of your daily fruit allowance. This will ensure you don’t overdo it on carbohydrates.
- ADD YOUR LIQUID
There are many choices when it comes to liquids, many people just add water or ice. Including plain, unsweetened dairy such yoghurt or milk not only contributes calcium and vitamin D which is important for bone health but also increases the protein content. This helps to lower the Glycaemic index (GI) of the whole smoothie (refer to article on GI & GL),2 which helps to prevent spikes in blood sugar levels.2,3 Bear in mind that dairy also contains carbohydrates, therefore contributing to the total carbohydrate content of the smoothie.
For dairy free options include a non-sweetened milk alternative such as soy, almond, rice, hemp, or a little bit of coconut milk. Other recipes also call for fruit juice, however for people living with diabetes, fruit juice isn’t recommended as it contains natural sugars but no fibre. Remember these smoothies contain multiple ingredients that contain carbohydrates, fruit juice will push the carbohydrate content up quickly.
- BOOST NUTRITION
Protein & Fat
Including a source of protein and fat in your smoothie is helpful as they both slow the rate at which the meal leaves the stomach. This slows down the absorption of the sugars into your blood which prevents spikes in blood sugar levels.
Ways to boost the protein content would be to add a protein powder such as whey and /or casein which is milk based or a plant based protein powder include hemp, soy, brown rice, and pea.
Include the following healthy fats in your smoothie: 1 small handful of nuts, 1 – 2 Tablespoons of seeds, ½ small avocado (gives your smoothie a creamy texture), 1 tablespoon of sugar free nut butter and 1 teaspoon of seed oils e.g. coconut, flaxseed, macadamia or olive.
Whole grains can also be a useful addition to the smoothie as they contribute texture and boost the nutritionals by adding vitamins, minerals, fibre, and protein and are low GI. Oats or oat bran are a great option. Remember to watch portions as they will contribute to the carbohydrate content
Don’t add extra sweeteners; remember fruits and dairy contain natural sugars already.
Remember to consider the carbohydrate content of the total smoothie. This should be no more than 1 – 3 carbohydrate exchanges depending on if it’s a meal or snack.
