What Counts Towards Your 5-a-day?
The 5-a-day recommendation is based on the significant health benefits associated with a diet rich in fruits and vegetables, including reduced risk of heart disease, stroke, and certain cancers [1]. A portion is generally defined as 80 grams of fresh, frozen, or canned fruit or vegetables [2]. This can include a medium apple, three heaped tablespoons of cooked vegetables, or a small glass of fruit juice.
The Role of Fruit Juice in Your 5-a-day
Fruit juice can contribute to your 5-a-day intake, but with important limitations. A 150ml glass of 100% unsweetened fruit juice, including apple juice, is considered one portion [2]. However, regardless of how much fruit juice you drink, it will only ever count as a maximum of one portion per day [2]. This is because the juicing process removes much of the beneficial dietary fibre found in whole fruit [3]. Without this fibre, the natural sugars in the juice, often referred to as 'free sugars,' are absorbed more quickly into the bloodstream, which can lead to a rapid rise in blood sugar levels [2, 4]. For this reason, health authorities advise limiting fruit juice and smoothie consumption to no more than 150ml per day [2].
Whole Fruit vs. Juice: A Nutritional Comparison
Choosing whole fruit over fruit juice offers several nutritional advantages. The fibre in whole fruits like apples contributes to digestive health, helps regulate blood sugar, and promotes satiety, which can be helpful for weight management [3, 5]. Juicing removes this fibre, meaning you miss out on these benefits [3].
Table: Nutritional Differences
| Feature | Whole Apple (with skin) | 150ml 100% Apple Juice | 
|---|---|---|
| Dietary Fibre | High | Low or negligible | 
| Sugar Absorption | Slower due to fibre | Rapid (free sugars) | 
| Satiety | Higher | Lower | 
| Vitamins & Minerals | Generally higher levels | Some loss during processing | 
| Dental Health Impact | Less impact | Higher risk of enamel erosion | 
Potential Downsides of Excessive Juice Consumption
Drinking large amounts of fruit juice can have negative health consequences. The high sugar content, even from natural sugars, can contribute to weight gain and increase the risk of type 2 diabetes when consumed in excess [4, 6]. The acidity and sugar in juice can also be detrimental to dental health, increasing the risk of tooth decay [6]. Furthermore, without the fibre to promote fullness, it's easy to consume more calories from juice than you would from eating whole fruit [6].
Healthy Alternatives and Tips
To ensure you're getting the most out of your fruit and vegetable intake, prioritise whole foods. Here are some tips:
- Eat the fruit: Opt for a whole apple, pear, or orange instead of juice [2].
- Include fruit in meals: Add berries to your breakfast cereal or slices of apple to a salad [2].
- Make smart smoothies: If you enjoy smoothies, blend whole fruits (including skins where edible) and vegetables to retain the fibre [4]. Keep smoothie portions to 150ml and count it as just one of your 5-a-day [2].
- Vary your intake: Consume a wide variety of fruits and vegetables to get a broad range of nutrients [1].
- Choose water or milk: These are better choices for hydration and general consumption throughout the day compared to fruit juice [6].
Conclusion
While a 150ml glass of 100% unsweetened apple juice does count as one of your 5-a-day portions, it should not be relied upon as a primary source of fruit intake. The fibre and nutrients lost in the juicing process, combined with the faster absorption of sugars, make whole fruit a significantly healthier option. For optimal health and to meet your 5-a-day goal effectively, focus on consuming a diverse range of whole fruits and vegetables daily. Limit fruit juice and smoothies to a small, occasional serving, ideally consumed with a meal [2, 6].
