This or That: Is Green Juice Healthier Than a Protein Smoothie?
Health enthusiasts may agree on many nutrition topics, but there’s one that's still up for debate: What should be your go-to fitness beverage, protein smoothie or green juice? Let’s find out.
Picture this: You’re one week into the new year and you’ve finally made up your mind on adopting a healthier lifestyle. You start by religiously working out every day and making a vow to go cold turkey on that junk food addiction. What comes next? Replacing your old eating habits with new ones. This is where you find yourself in a pickle. Should you start your day with a protein-packed smoothie or perhaps a refreshing glass of green juice is better for you? Confused on which blend contains the highest concentration of nutrients? Allow us to clear things up for you.
Let’s start with the basics. What exactly is green juice? Well, in layman’s terms, it is the liquid extracted from (usually) green fruits and vegetables that contains all the good plant stuff like nutrients and enzymes. Some people might be wary of juices because they usually eliminate insoluble fibre. However, most juices already contain some amount of “soluble” fibre, despite being devoid of fleshy plant material. The key is to choose fruits and vegetables that contain a good amount of that gut-friendly soluble fibre. Kale, apple, spinach, pineapple, carrots—all are excellent sources of the soluble fibre we’re talking about.
Research also suggests that juices not only retain most nutrients found in fruits and vegetables but also successfully transport them to our bodies. A study by Dr Julia K Kolodziejczyk, San Diego State University, California, USA, found that beta-carotene, a beneficial nutrient, obtained from juiced produce rather than whole food forms, resulted in higher blood levels of beta-carotene. In other words, the juice was more readily absorbed by the subject’s body. The research also stated that soluble fiber reduces beta-carotene absorption by 30 to 50 per cent.

Now moving on to our second contender of the day, a protein smoothie is a beverage usually prepared by blending fruit, vegetable, and a certain liquid into a puree. The liquid can be yoghurt, milk, buttermilk, or simply water—and if it’s water, the protein content is usually achieved with the addition of protein powder. Think of a protein smoothie like a nutritious salad that you have to drink. Smoothies contain plant pulp which means that they also contain the insoluble fibre that juices usually get rid of. Now this is both a pro and a con. On one hand, it aids digestion in people that are already blessed with a strong gut. But if you have a weaker digestive system, your body might have to work extra hard to extract these precious nutrients. And in the process, it sometimes loses more energy than it gains.
However, insoluble fibre has shown to contain more antioxidants than its soluble counterpart. According to a 2012 study by Dr Ram M Uckoo, Vegetable and Fruit Improvement Center, Department of Horticultural Sciences, Texas University, USA, blended grapefruit contains a significantly higher concentration of phytochemicals and antioxidants because these compounds are found in the fibrous membranes of the fruit—as compared to grapefruit juice which doesn’t include those elements.

After closely comparing the pros and cons of these highly sought-after healthy beverages, we’ve come to the conclusion that there is no right way of consuming fruits and vegetables. It all comes down to your needs and requirements. If you can afford to sit down and eat a complete breakfast in the morning, then go ahead, pair it with a fresh glass of green juice. But if you’re usually on the run and have a habit of skipping breakfast, a protein-rich smoothie might be your best friend. But don’t just rely on artificial protein powder as it can be high in sugar. Instead, try adding ground flax seeds, chia seeds and almonds for that extra dose of protein and Omega-3.
When it comes to green juice vs protein smoothies, the debate should be turned away from “Which of the two is better?” into “What do I need right now?” Everyone is different, including our lifestyles and dietary habits. You might need a smoothie post workout but a glass of juice for that extra dose of macro and micro nutrients. And that’s perfectly okay.
