Different dietary approaches have positive effect on immune markers for patients with metabolic syndrome.

Low-fat diets reduce C-reactive protein, though this seems to be dependent on weight loss.

Low-carbohydrate diets can be considered as additional intervention to achieve weight control.

Reducing saturated fatty acids and enriching immunoactive biosubstances (vitamins, flavonoids, and unsaturated fatty acids) seems to be the best strategy against metabolic syndrome.
