Kate Middleton is said to kick off her morning with a nutrient-rich beverage that may surprise many. Recognised for her dedication to healthy eating and regular exercise routine, the Princess of Wales combines seven ‘powerhouse’ components for her dawn energy boost.

While you might expect a Royal variation on the standard morning brew or cuppa, Kate’s preference is actually a ‘green juice’, according to reports from Hello! and MailOnline. Her concoction is believed to feature a potent mixture of kale, spinach, romaine lettuce, coriander, blueberries, spirulina powder, and merely a small teaspoon of matcha powder.

At first glance, it seems like the pinnacle of wellness. But does it justify the buzz? The Mirror previously asked Helen Bell, a nutritionist from Help & Advice, about the beverage, which some have jokingly dubbed ‘pondwater’ after sampling it.

Impressively, she noted that four elements of this drink are categorised as ‘superfoods’, describing exceptionally nutritious products. “In my experience, the term ‘superfood’ is often thrown around,” she told the publication.

“But it generally refers to foods that are nutrient-rich and beneficial for health and wellbeing. In Kate’s smoothie, several ingredients could be considered superfoods.

“For instance, kale, spinach, and spirulina are packed with vitamins, minerals, and antioxidants. Blueberries are another example, known for their high antioxidant content.

“Matcha, a type of green tea, is known for its concentration of catechins, which are natural antioxidants.” Helen said that incorporating these components into your daily meals could ‘contribute positively to cholesterol levels’.

Leafy vegetables, including kale and spinach, are especially recognised for their potential ability to help lower ‘bad cholesterol (LDL) levels’. During another conversation, Helen also described spinach as a ‘powerhouse’ of nutrients and antioxidants, believed to possibly shield the body from chronic illnesses.

Some studies highlight a possible link between spinach intake and reduced cancer risk as well, though further research is required. Helen continued: “Blueberries also play a role in heart health, potentially improving cholesterol levels and supporting cardiovascular health.

“While no single food will drastically change cholesterol levels, a balanced diet rich in these ingredients can certainly support heart health.”

However, it’s not entirely about the advantages – Helen offered a key warning concerning the green juice craze. She added: “While the ingredients in the smoothie are generally beneficial, it’s important to be mindful of individual dietary needs.

“For example, those with thyroid issues might need to moderate their intake of raw kale and spinach due to their goitrogen content. Spirulina and matcha are potent, so I advise starting with small amounts to ensure they agree with your system.

“In my experience, balance is key, and it’s always wise to consult with a healthcare provider, especially if you have specific health concerns.”
