How to eat it
Introduce slowly, sunchokes' high inulin content can cause significant gas and bloating in people unaccustomed to it; cooking thoroughly helps somewhat.
Pairs well with
Fermented foods (yogurt, kefir), inulin feeds the same probiotic bacteria these foods supply
Garlic and onions, other inulin-rich foods that compound the prebiotic effect
Storage
Refrigerate in a perforated bag; use within 1-2 weeks, as they're more perishable than other root vegetables.

Evidence
B
Genuine human prebiotic evidence, with a well-documented and pronounced downside that is worth quantifying rather than hiding.
Study dose vs. serving
5 g/day inulin significantly increased bifidobacteria and Lactobacillus/Enterococcus. A pilot showed 100 g or more grated sunchoke before a meal reduced postprandial glucose and GIP. Realistic serving.
Ramnani P, et al. Br J Nutr. 2010. 66 healthy adults, double-blind placebo-controlled, Jerusalem-artichoke-derived inulin 5 g/day.
Use caution if
You have IBS or are FODMAP-sensitive, sunchokes are one of the higher-FODMAP vegetables and a very common trigger
You're newly introducing them, start with very small portions

Inulin - sunchoke is among the richest food sources at about 10-22% by fresh weight
Heat stable
Yes - inulin survives ordinary cooking
Watch
PRONOUNCED FLATULENCE: in the Ramnani trial, flatulence scores rose significantly with inulin versus placebo (0.98 vs 0.44 on a 0-3 scale), though remaining mild. High-FODMAP - a food to limit on a low-FODMAP diet for IBS.
