When it comes to managing blood sugar levels, many people focus on diet and exercise. However, a lesser-known factor that can impact glucose control is tea consumption. Research suggests that certain teas may have a positive or negative effect on blood sugar regulation.

Steeping Up the Antioxidants: How Tea Can Help Regulate Blood Sugar

Drinking green tea has been shown to improve insulin sensitivity in both healthy individuals and those with type 2 diabetes (1). This is likely due to its high antioxidant content, which includes catechins like EGCG. A study published in the Journal of Nutrition found that consuming a beverage rich in EGCG reduced blood glucose levels by an average of 12% after meals.

The Tea Leaves That Can Spike Blood Sugar

However, not all teas are created equal when it comes to blood sugar regulation. Consuming large amounts of black tea or those containing high levels of added sugars can actually cause spikes in blood glucose (2). In one study, participants who drank sweetened beverages experienced a 10-15% increase in fasting blood glucose compared to those consuming unsweetened drinks.

The Connection Between Tea and Insulin Sensitivity

Some teas have been found to improve insulin sensitivity, which is essential for maintaining healthy blood sugar levels. For example, oolong tea has been shown to reduce body mass index (BMI) and waist circumference in obese individuals by improving glucose metabolism (3). This suggests that drinking certain types of tea may be a useful adjunctive therapy for those trying to manage their weight or improve insulin sensitivity.

The Role of Catechins in Blood Sugar Regulation

The catechin content found in green tea is thought to play a key role in its blood sugar-regulating effects. EGCG, the most abundant catechin present in tea leaves, has been shown to activate AMP-activated protein kinase (AMPK), an enzyme that improves insulin sensitivity and glucose uptake by cells (4). This suggests that drinking green tea regularly may be beneficial for those looking to improve their body's ability to regulate blood sugar.

Can Drinking Tea Really Make a Difference?

The evidence supporting the potential benefits of tea consumption on blood sugar regulation is promising, but more research is needed. While it is unlikely that drinking one or two cups of tea per day will significantly impact glucose levels, incorporating green or oolong tea into your daily routine may have a beneficial effect over time.

Choosing the Right Tea for Your Blood Sugar Needs

Not all teas are created equal when it comes to blood sugar regulation. When selecting a type of tea to drink, consider opting for those that contain high levels of antioxidants and catechins. Green or oolong tea is likely your best bet, but be mindful of added sugars in sweetened beverages.

Episode 303: Join us on Dadvice TV as Dr. Rosansky and I dive into the latest breakthroughs in Chronic Kidney Disease treatment, specifically targeting how to slow the progression of CKD Stage 3. In this enlightening conversation, we'll explore innovative strategies, recent research, and practical tips to manage your kidney health more effectively. Whether you're navigating the challenges of CKD Stage 3 or supporting someone who is, this video will provide valuable insights into extending the health and functionality of your kidneys. Main Discussion 1. CKD3 Explained: * Dr. Rosansky explained that CKD3 is divided into CKD3A (GFR 45-60) and CKD3B (GFR 30-45). Many people with CKD3A may not even have kidney disease, especially older adults. * It's crucial to have two GFR values below 60, taken three months apart, to confirm CKD. 2. Protein in the Urine: * The presence of protein in the urine is a key indicator of kidney disease progression. * Urine protein levels are classified as mild, moderate, or severe, with consistent high levels indicating significant risk. 3. Importance of Monitoring: * Regular monitoring of GFR and urine protein is essential. Even a 25% variation in GFR can be significant. * Patients should ensure their doctors check urine protein regularly. 4. Latest Research and Treatments: * A recent Canadian study showed that some CKD patients' kidney function improved by 25% over five years, highlighting the variability in kidney disease progression. * The likelihood of progression to dialysis is much lower for older adults, especially those with minimal protein in their urine. 5. New Medications: * Dr. Rosansky discussed the benefits of ACE inhibitors, ARBs, and the newer SGLT2 inhibitors. These medications can significantly slow the progression of kidney disease and best breakfast for high blood sugar reduce the risk of heart-related issues. * He also mentioned the high cost of newer medications and the importance of evaluating their necessity based on individual risk factors. 6. Diet and Lifestyle: * Exercise and a plant-based diet are crucial for managing kidney disease. Maintaining a healthy lifestyle can significantly reduce the risk of heart disease and other complications. Medications Dr. Rosansky spoke about: 1. ACE Inhibitors: ACE inhibitors work by blocking the action of the enzyme responsible for the production of angiotensin II, a hormone that narrows blood vessels and increases blood pressure. Some common ACE inhibitors include: Benazepril (Lotensin) Captopril (Capoten) Enalapril (Vasotec) Fosinopril (Monopril) Lisinopril (Prinivil, Zestril) Quinapril (Accupril) Ramipril (Altace) 2. ARBs: ARBs block the action of angiotensin II by preventing it from binding to its receptor. This helps relax blood vessels and lower blood pressure. Some common ARBs include: Candesartan (Atacand) Irbesartan (Avapro) Losartan (Cozaar) Olmesartan (Benicar) Telmisartan (Micardis) Valsartan (Diovan) 3. SGLT-2 Inhibitors: Canagliflozin (Invokana) Dapagliflozin (Farxiga) Empagliflozin (Jardiance) Ertugliflozin (Steglatro) Sotagliflozin (Zynquista) 4. GLP1 agonists: Dulaglutide (Trulicity) Exenatide extended release (Bydureon BCISE) Exenatide (Byetta) Semaglutide (Ozempic) Liraglutide (Victoza, Saxenda) Lixisenatide (Adlyxin) Semaglutide (Rybelsus) 5. Aldosterone receptor antagonists: Eplerenone (Inspra) Spirinolactone (Aldactone) Finerenone (Kerendia) Get Dr. Rosansky's helpful book "Learn The Facts About Kidney Disease" at Dr. Rosansky is a highly respected nephrologist and an esteemed author of the book "Learn the Facts about Kidney Disease".
