Most people only think about sugar when they think about what burns through vitamin B1. This clip looks at the other side of the equation, why refined vegetable oils and unstable polyunsaturated fats are also being blamed for increasing oxidative stress and adding to the body’s thiamine burden. If the modern diet is hitting B1 from both directions, refined carbs on one side and oxidized fats on the other, that changes the whole conversation.

Refined carbs do not just spike blood sugar. They can also burn through the very nutrient your body needs to handle them. This clip breaks down the hidden B1 connection behind sugar, white rice, processed food, and the modern Western diet, and why so many people may be running low without realizing it. When the food is stripped down and the thiamine is gone, the body ends up paying the price.

This clip breaks down a much bigger idea than simple vitamin deficiency. In neurodegeneration, the real problem may be that the brain cannot properly use thiamine where it matters most. That is why high-dose B1 is being discussed, not just to “replace” a deficiency, but to push past a metabolic block and help restart energy production in the brain. It also raises a fascinating question: when people with dementia or Parkinson’s crave sugar constantly, are they trying to compensate for a brain that is struggling to make energy?
