Inulin Type Fructans and Phosphate Absorption

In most studies so far reported, phosphate absorption and P serum concentration were not affected by inulin-type fructans neither in rats77,79,109,111,141-143 nor in dogs.115

However, in their publication of 1993, Ohta et al. had reported a slight (+13.5%) but significant increase (p < 0.05) in that parameter in rats fed a diet containing 15% (w/w) oligofructose.109 But, and in the same publication, these authors reported either no change or an increased phosphate absorption as well as an increased P content of femur (+19%) at a dietary oligofructose concentration of 5%. The increse in Ca absorption declined progressively with time (+13.5, +6, and +5% at day 7, 18, and 31, respectively).109

In gastrectomized rats (4-week-old male Sprague-Dawley) that were used to test for the preventing effect of oligofructose (10% w/w in diet for 10 d) on osteopenia known to occur in gastrectomized patients, a significant increase in P absorption was reported when comparing the gastrectomized rats fed the oligofructose-contain-ing diet the control sham-operated rats (89 and 76.5%, respectively or a 16% increase). But in the two groups of gastrectomized rats the absorption of P was similar (89 and 92%).131

Dieting Dilemma and Skinny Solutions

The captivating thing about diets is that you don't get what is researched or predicted or calculated but rather, you get precisely what you expect. If the diet resonates with you then it will likely work, if it doesn't resonate, it won't.
