• Refined carbohydrates are bad for you
• Refined sugar is especially bad for you

• Saturated fats are good for you
• Common cooking oils are moderately bad, including canola, corn, soy, and safflower
• Soy is bad for you unless it's fermented
• Wheat is usually bad for you, but it doesn't have to be
• Some natural foods are bad for you
