Ok let’s talk alcohol
In the initial stages of the ketogenic diet, drinking alcohol can have several negative effects. For instance, the body prioritizes alcohol metabolism over fat burning, which can interrupt ketosis. Additionally, the liver, already focused on producing ketones, can become strained by alcohol intake, impacting its overall efficiency. Alcohol can also cause fluctuations in blood sugar levels, particularly if it contains hidden sugars, further disrupting ketosis. Moreover, as alcohol metabolizes into acetaldehyde—a toxic compound—it increases stress on the liver. Lastly, alcohol consumption can lead to dehydration and electrolyte imbalances, both of which are critical considerations for those following a ketogenic diet.
Polyphenols are a group of naturally occurring compounds found in plants and are classified as phytochemicals. These beneficial compounds are recognized for their antioxidant properties, helping to protect the body's cells from damage caused by free radicals. Research suggests that polyphenols may offer various health benefits, including anti-inflammatory effects, support for cardiovascular health, improved blood sugar control, and a reduced risk of chronic diseases such as heart disease, certain types of cancer, and neurodegenerative disorders. Although the potential health benefits of polyphenols are promising, further research is needed to fully understand their mechanisms of action.
To ensure a good intake of polyphenols, it is beneficial to include a variety of plant-based foods in your diet. Berries, particularly raspberries, blackberries, and strawberries, are lower in carbohydrates and can be enjoyed in moderation on a ketogenic diet. Dark chocolate, when chosen with a high cocoa percentage and minimal added sugars, offers a delicious treat while providing polyphenols. Green tea is another excellent source that is low in carbs, making it a perfect beverage choice. Nuts and seeds, such as almonds and walnuts, are keto-friendly options that also deliver healthy fats and fiber. Extra virgin olive oil is rich in polyphenols and healthy fats, ideal for cooking and salad dressings. Avocado, a fruit high in healthy fats, is also a great source of polyphenols. Dark leafy greens like spinach and kale contribute additional nutrients, while various herbs and spices can enhance flavor while providing polyphenolic benefits.
Resveratrol, a specific type of polyphenol found predominantly in red grapes and red wine, has garnered attention for its potential health benefits. Known for its antioxidant and anti-inflammatory properties, resveratrol acts as a powerful protector against cellular damage. Research has suggested that it may offer cardioprotective effects, improving blood flow and supporting vascular health, while also demonstrating potential anti-cancer properties. Additionally, resveratrol has been studied for its effects on brain health, potentially protecting against neurodegenerative diseases like Alzheimer’s and Parkinson’s, and is believed to have anti-aging effects by activating certain longevity-related genes.
While red wine can indeed be a source of polyphenols, including resveratrol, it is essential to consume it responsibly, especially within the context of a ketogenic diet. When selecting red wine, it is beneficial to choose varieties made from red grapes, as they generally contain higher levels of polyphenols compared to white wines. Grapes with thicker skins, such as Cabernet Sauvignon, Merlot, and Pinot Noir, are known to have increased polyphenolic content. Wines that undergo longer fermentation periods may also retain higher levels of these beneficial compounds. Additionally, seeking organic or biodynamic wines can be advantageous, as these practices often preserve natural compounds, including polyphenols.
Our recommendation is a French Pinot Noir, better with a cork top and look to be spending over £15 per bottle
While red wine can provide polyphenols and resveratrol, moderation is crucial. For individuals in the UK, the recommended alcohol intake limit is 14 units per week, spread over several days or with at least seven alcohol-free days in between. By adhering to these guidelines, individuals can maintain a balanced lifestyle while prioritizing their health and well-being. It is important to remain committed to health goals and make informed choices as part of the ketogenic journey.
