Sv: IR och olja
Kanske inte den mest tillförlitliga källan den sidan.
Påståendet i sig är inte helt fel, men de har tagit det ur sitt sammanhang. En kombination av olja och fiber kan sänka GI, och det spelar stor roll VILKEN olja det är osv.

Fat and fiber feeds, such as those under development at Virginia Tech (Kronfeld et al., 1996), have enough fiber to be fed exclusively as complete feeds, and enough fat to be used as typical concentrate feeds. They all contain approximately 12% vegetable oils, rich in omega-6 fatty acids, but they vary in carbohydrate profiles for specific purposes: for example, repeated sprints or pasture supplementation for growth (Hoffman and Kronfeld, 1999; Graham-Thiers et al., 2001). Compared with a typical sweet feed,
one of our fat and fiber feeds has lowered the glycemic response by 40% and the insulinemic response by 85% (Williams et al., 2001). It also avoided the insulin insensitivity that develops during chronic adaptation to sweet feed (Hoffman et al., 2003; Treiber et al., 2004a).
In many species,
insulin sensitivity has been decreased by feeding saturated fat but has been increased by feeding polyunsaturated, omega-6 fatty acids (Storlien et al., 2000). The omega-3 fatty acids also improve insulin sensitivity in rats but not humans (Revillese and Lilli, 2003). Administration of omega-3 fatty acids has been claimed to prevent starch-induced laminitis in horses (Neeley and Herthel, 1997). Menhaden oil modulates leukotriene synthesis in horses and may influence inflammatory conditions (Hall et al., 2004), including the inflammatory component of insulin resistance (Fitzgerald, 2004).

Feeding more calories without exacerbating IR
Some insulin resistant horses have a leaner overall body condition, but still
exhibit regional adiposity. These horses may be older and suffer from equine Cushing’s disease. Other horses may be exercising strenuously or competing, so they require more calories. If hay is not sufficient to provide these calories, a concentrate must be selected. Thin insulin resistant horses can be fed concentrates, but care must be taken to provide calories without exacerbating IR.
There are three considerations when evaluating
feeds for insulin resistant patients: 1) the sugar content of the feed, 2) the glycemic response after feeding (how high the blood glucose levels go after eating), and 3) feeding practices.
Feeds containing less starch and sugar are appropriate in these situations. It is also advisable to feed hay before concentrates and to feed smaller meals more frequently.
Feeding strategies include:
1. A diet consisting of hay with a low (< 12%) NSC content, pelleted specialty feed for IR horses, vitamin and mineral supplement, and 0.5 cup (equal to 125 mL; contains approximately 100g fat)
rice bran oil or corn oil twice daily.
2. The same diet with molassesfree beet pulp substituted for pelleted specialty feed.
3. Either of the above diets with rice bran substituted for oil. Rice bran contains approximately 20% fat and 1 lb (approximately 90 g fat) can be fed twice daily.
4. A pelleted specialty feed for geriatric horses in older patients with muscle loss or dental problems (> 20 years of age).

Nu har ju inte mina hästar problem med insulinet (vad jag vet iaf) men jag fick uppfatningen att om man fodrar med mkt olja så kan man förstöra glukos omsättningen även på en frisk häst, vilket då kan leda till fång.
