Chop, Wait, Then Cook: A Simple Trick to Boost Vegetable Health Benefits
Letting chopped vegetables rest before cooking enhances sulforaphane levels, supporting heart health, balanced blood sugar, and a healthier gut microbiome
While this may surprise you, leaving your chopped vegetables on the counter for 10 minutes before cooking, may in fact lower your risk of heart disease.
Scientist Professor Tim Spector claims that allowing chopped onions and garlic to "rest" for 10 minutes before cooking boosts the levels of a compound called sulforaphane, which can help reduce cholesterol and stabilize blood sugar levels.
Sulforaphane is a compound found primarily in cruciferous vegetables like broccoli, cabbage, cauliflower, radishes, onions, and garlic. Studies have shown that cooking can destroy the enzyme myrosinase, which is essential for producing sulforaphane. However, according to Spector, letting vegetables sit for 5–10 minutes after chopping or crushing allows enough sulforaphane to form and survive the cooking process.
Leaving chopped vegetables to rest before cooking is just one of many fascinating recommendations from Professor Tim Spector, a renowned researcher in the field of microbiome and nutrition. In his book “The Diet Myth,” Spector presents several key principles based on his research into the microbiome and dietary health:
Dietary Diversity – Consuming a wide variety of foods, especially plant-based sources, promotes a rich and diverse gut microbiome, which positively impacts overall health.
Reducing Processed Foods – Avoiding highly processed foods that are rich in sugars and trans fats, as they can harm the gut microbiome diversity and lead to health issues.
Eating Fermented Foods – Incorporating foods like yogurt, kefir, sauerkraut, and pickled vegetables, which help increase the population of beneficial gut bacteria.
Understanding Fats – Recognizing that not all fats are harmful; unsaturated fats from sources like olive oil, avocados, and nuts can be beneficial to health.
Personalized Nutrition – Acknowledging that every individual reacts differently to various foods, making it essential to tailor the diet to personal preferences and needs.
Avoiding Restrictive Diets – Steering clear of diets that eliminate entire food groups to maintain dietary diversity and gut health.
Minimizing Antibiotics Use – Avoiding unnecessary antibiotic consumption, as it can damage the diversity of gut bacteria.
Understanding Fiber’s Role – Recognizing the importance of dietary fiber, which serves as food for beneficial gut bacteria and supports digestive health.
Avoiding Artificial Sweeteners – Steering clear of artificial sweeteners, which may negatively impact the gut microbiome and contribute to metabolic issues.
Reducing Sugar Intake – Limiting sugary foods and drinks to maintain stable blood sugar levels and overall health.
