Cooled Potatoes
Overview
Potatoes that are cooked and then cooled develop resistant starch through retrogradation, providing prebiotic fiber that supports gut microbiome and SCFA production. The complex carbohydrate, Resistant Starch, forms when certain starchy foods are cooked and then cooled, a process called retrogradation. Foods like rice and potatoes develop higher resistant starch content when chilled. White rice was cooled and reheated showing a rise in RS content from 0.64 to 1.65 g/100 g and elicited a lower glycemic response.

Preparation Notes
- Cook potatoes, then cool (refrigerate) to form resistant starch; resistant starch forms when certain starchy foods are cooked and then cooled, a process called retrogradation
- Reheating does not reverse resistant starch formation; white rice was cooled and reheated showing a rise in RS content from 0.64 to 1.65 g/100 g and elicited a lower glycemic response
- Supports butyrate production via gut fermentation; resistant starch (cooled potatoes, green bananas) supports Bifidobacterium, Akkermansia; ↑ butyrate production; improved gut barrier
- Lower glycemic response compared to hot potatoes; blunts post-prandial glycemic excursions
Biological Target Matrix
| Biological Target | Substance | Therapeutic Areas | Mechanism of Action |
|---|---|---|---|
| Hormonal Response | Vitamin C (Ascorbate) | Supports norepinephrine synthesis as cofactor | |
| Inflammation | Vitamin C (Ascorbate) | Antioxidant properties; supports anti-inflammatory effects | |
| Methylation | Vitamin B6 (Pyridoxine → PLP) | Essential cofactor in remethylation of homocysteine to methionine, which is converted to S-adenosylmethionine (SAMe); works with B2, folate, and B12 | |
| Neurochemical Balance | Potassium | Critical for membrane potential, nerve signaling, and neuronal excitability; adequate intake balances sodium effects | |
| Neurochemical Balance | Vitamin B6 (Pyridoxine → PLP) | Cofactor for synthesis of dopamine, serotonin, GABA, and glutamate; supports rate-limiting steps in catecholamine synthesis; requires PDXK activation with magnesium and ATP support | |
| Neurochemical Balance | Vitamin C (Ascorbate) | Supports norepinephrine synthesis; transported in brain via SVCT2 | |
| Oxidative Stress | Vitamin C (Ascorbate) | Key water-soluble antioxidant; works within antioxidant network with vitamin E, CoQ10, and polyphenols | |
| Stress Response | Vitamin C (Ascorbate) | Supports stress response through antioxidant and neurochemical effects |
