White asparagus

White asparagus is notable for FODMAPs, fructose and nickel. Clear on histamine, tyramine, salicylate, sucrose, lactose, oligosaccharides, sorbitol, oxalates and gluten.

White asparagus contains moderate levels of FODMAPs. White asparagus is the same plant grown under earth, and it is almost always peeled and boiled with the water thrown away - which takes some of the water-soluble fructans with it. That preparation, not the colour, is why it sits below the green spear. Jarred white asparagus loses more still, into the brine.

White asparagus contains moderate levels of fructose. White asparagus: this vegetable contains fructose and fructans that can trigger symptoms in fructose malabsorption, but it is dose-dependent, so a small portion is often tolerated. Eating it with a glucose source improves fructose absorption.

White asparagus contains only low levels of nickel. White asparagus is grown covered so it never greens, which means it develops entirely underground. That is more soil contact than green asparagus gets, and it is usually sold canned besides. The nickel here follows a survey of heavy metals in VEGETABLES. A vegetable takes up what its soil holds, so a figure of this kind describes the growing region as much as the plant. Amounts vary by brand and recipe, so always check the label of the exact product.
