Juices and smoothies dominate the wellness world, but beyond the trends, what does the science really say? And where does chewing fit into this picture? Let\u2019s break it down.<\/strong><\/p>\n\n\n\n

Juicing: Pros & Cons<\/h2>\n\n\n\n

Juicing extracts liquid from fruits and vegetables, removing fibre and leaving behind a concentrated nutrient-rich liquid. But this comes with pros and cons:<\/p>\n\n\n\n

\u2705 Higher Nutrient Bioavailability<\/strong>: Without fibre, certain micronutrients like Vitamin C and polyphenols are absorbed faster.<\/p>\n\n\n\n

\u2705 Easier Digestion:<\/strong> Juicing provides a rapid influx of vitamins without taxing the digestive system, which may benefit people with gut sensitivities.<\/p>\n\n\n\n

\u274c Lacks Fibre:<\/strong> Fibre is essential for gut health, blood sugar regulation, and satiety. Juices miss out on this crucial component.<\/p>\n\n\n\n

\u274c Fructose Overload:<\/strong> Fruit-heavy juices deliver a high sugar load without fiber, causing blood sugar spikes and potential metabolic stress. Studies show that excess liquid fructose consumption is linked to fatty liver disease, insulin resistance, and metabolic dysfunction.1<\/a><\/sup><\/p>\n\n\n\n

Debunking the Celery Juice Hype<\/h2>\n\n\n\n

Celery juice is often touted as a detox miracle, but there\u2019s no scientific evidence supporting these claims. While celery is rich in antioxidants and polyphenols, it doesn\u2019t \u2018cleanse\u2019 your body\u2014that\u2019s your liver and kidneys’ job (Bjarnadottir, 2020). Whole celery or blended celery in smoothies retains fibre, supporting gut health far better. The “Medical Medium” is Anthony William, a self-proclaimed health expert who gained popularity for promoting the celery juice trend. Notably, he has no formal medical or scientific qualifications. William claims his health advice comes from a “spirit” that provides him with medical information. Despite his large following, especially among celebrities, none of his claims\u2014including that celery juice can cure conditions like cancer, autoimmune diseases, or chronic illnesses\u2014are supported by scientific evidence. Health professionals and scientists widely criticise his advice for lacking credible research and potentially misleading vulnerable individuals seeking legitimate medical guidance. <\/p>\n\n\n\n

That said, celery juice isn\u2019t without benefits. It\u2019s hydrating, low in calories, and rich in vitamins, minerals, and antioxidants like luteolin and apigenin, which may support overall health. Enjoy it as part of a balanced diet\u2014but skip the miracle claims and focus on the real, science-backed benefits.<\/p>\n\n\n\n

Why Smoothies Might Be the Better Option<\/h2>\n\n\n\n

Unlike juices, smoothies retain the whole fruit or vegetable, keeping fibre intact, which slows digestion and prevents blood sugar spikes.2<\/a><\/sup><\/p>\n\n\n\n

\u2705 Balanced Nutrient Delivery:<\/strong> Smoothies provide fibre, protein, and healthy fats, modulating blood sugar and promoting satiety.<\/p>\n\n\n\n

\u2705 Supports Gut & Metabolic Health:<\/strong> Fibre feeds gut bacteria and helps regulate digestion.<\/p>\n\n\n\n

\u2705 Better for Blood Sugar Stability:<\/strong> Adding nuts, seeds, yogurt, or Formett\u0101 slows glucose absorption compared to fruit juice alone.<\/p>\n\n\n\n

The Science of Blending: What Happens When You Blend?<\/h2>\n\n\n\n

Blending breaks down plant cell walls, releasing nutrients trapped within, making them more bioavailable.<\/p>\n\n\n\n

\u2705 <\/strong> Increased Nutrient Absorption:<\/strong> Blending frees polyphenols, carotenoids, and flavonoids, enhancing absorption.<\/p>\n\n\n\n

\u2705 Faster Digestion:<\/strong> Liquids pass through the stomach quicker, making nutrients available sooner.<\/p>\n\n\n\n

\u2705 Reduced Fibre Structure:<\/strong> While smoothies retain fibre, blending alters its structure, making it gentler on digestion.<\/p>\n\n\n\n

<\/p>\n\n\n\n

Potential Downsides of Blending<\/h3>\n\n\n\n

While blending enhances nutrient absorption, it has drawbacks:<\/p>\n\n\n\n

\u274c Reduced Satiety:<\/strong> Blended foods require little chewing, potentially reducing satiety hormone activation.<\/p>\n\n\n\n

\u274c Rapid Blood Sugar Spikes:<\/strong> High-sugar smoothies can cause glucose spikes without fiber to slow absorption.<\/p>\n\n\n\n

\u274c Loss of Thermic Effect:<\/strong> Chewing and digesting whole foods require more energy, boosting metabolism slightly\u2014an effect reduced with blended foods.<\/p>\n\n\n\n

<\/p>\n\n\n\n

The Science of Chewing: More Than Just Breaking Down Food<\/h2>\n\n\n\n

While smoothies and juices offer a convenient, nutrient-packed option for busy lifestyles, it\u2019s important to understand the critical role that chewing plays in digestion, metabolism, and overall health. Blending may have its benefits, but the act of chewing engages complex physiological processes that blending simply can\u2019t replicate.<\/p>\n\n\n\n

    \n
  1. Appetite Regulation and Satiety:<\/strong> A systematic review and meta-analysis by Sophie Miquel-Kergoat et al. (2015) titled “Effects of Chewing on Appetite, Food Intake and Gut Hormones”<\/em> revealed that increased chewing reduces hunger and food intake. This is partly due to enhanced secretion of gut hormones such as GLP-1 (glucagon-like peptide-1) and PYY (peptide YY), which signal fullness to the brain.<\/li>\n\n\n\n
  2. Digestive Enzyme Activation:<\/strong> Chewing stimulates saliva production, which contains enzymes like amylase and lipase that start breaking down carbohydrates and fats right in the mouth. This pre-digestion process improves nutrient bioavailability and reduces digestive strain on the stomach and intestines.<\/li>\n\n\n\n
  3. Enhanced Nutrient Absorption:<\/strong> Research shows that thoroughly chewed food results in smaller particles, increasing the surface area for digestive enzymes to act upon. This leads to better absorption of key nutrients, especially in fibrous plant foods.

    Striking the Right Balance<\/h2>\n\n\n\n

    Smoothies are convenient, but incorporating whole foods that require chewing supports appetite regulation, digestion, and metabolic health. If you enjoy Formett\u0101 in smoothies, add ingredients like nuts, seeds, or fruit chunks to maintain the benefits of chewing.<\/p>\n\n\n\n
