Mold-Affected Yam: Why Cutting Off the Bad Part Isn’t Enough — A Food Scientist’s Guide to Aflatoxin Safety

Image
  That small white or green patch on your yam? It’s not just surface dirt. It could be a serious food safety hazard. If you’re Nigerian or West African, yam is likely a staple in your kitchen. But there’s a hidden danger that most households don’t know about: Aspergillus mold and the aflatoxins it produces. And no, scraping off the visibly moldy part doesn’t make the rest safe to eat. As a food scientist, I want to break down what’s really happening at a microscopic level, and what you should do to protect your family’s health. What’s Actually Growing on Your Yam? The fluffy white, green, or black growth you see on cut yam is Aspergillus, a common environmental fungus. The most concerning species is Aspergillus flavus , which produces aflatoxins toxic compounds classified by the World Health Organization as Group 1 carcinogens. Here’s the part most people miss: what you see on the surface is only the “fruiting body” of the fungus. The real problem lies beneath. Fungal hyphae ...

  If you’re planning a 6+ hour journey, this is the one health guide you shouldn’t skip Sitting still for hours whether you’re on a Lagos to London flight, an Abuja to Accra road trip, or a cross-country bus ride might seem harmless. But for adults over 55, prolonged immobility can silently increase your risk of Deep Vein Thrombosis (DVT), a potentially life-threatening blood clot condition. As a medical expert, I’m seeing more cases of travel-related DVT in patients who thought they were “too healthy” for it to happen. The good news? It’s largely preventable if you know what to do before, during, and after your journey. What Is Deep Vein Thrombosis (DVT)? DVT is a blood clot that forms in a deep vein, usually in the legs. When you sit for long periods, blood flow in your legs slows down. If blood pools and clots, it can partially or completely block the vein. The real danger comes if that clot breaks off and travels to your lungs a condition called pulmonary embolism (PE). PE can ...

Stroke Isn’t Just an “Old Person’s Disease” Anymore — Here’s What Everyone Needs to Know

  Stroke used to be something we associated with our grandparents. Today, I’m seeing it in patients in their 30s and 40s. In clinics, stroke is becoming increasingly common, and one of the biggest problems is that many people don’t understand what it actually is or what puts them at risk until it’s too late. Let’s break it down, plain and simple. What Exactly Is a Stroke? A stroke happens when blood supply to part of the brain is cut off. Without oxygen and nutrients, brain cells begin to die within minutes. And because the brain controls everything movement, speech, breathing, memory; the damage can be life-altering or fatal. There are two main types: Ischaemic Stroke – This is the most common type, about 80% of cases. It occurs when a blood clot blocks an artery supplying the brain. Think of it like a traffic jam in your blood vessel. Haemorrhagic Stroke – This happens when a blood vessel in the brain ruptures or leaks. Instead of blood reaching the brain, it spills into the surr...
