Oats are cheap, and oatmeals might improve your immune system and insulin sensitivity.
Researchers in Chicago carried out a randomized, double-blind, controlled clinical trial of 97 men and women, in which half of the group consumed foods containing oat beta-glucan, while the other half ate control foods. The oat group showed improvements in insulin sensitivity, while the control group was unchanged. (European Journal of Clinical Nutrition, June 2007)
Researchers in Mannheim, Germany carried out a dietary intervention with 14 patients who had uncontrolled type 2 diabetes and insulin resistance. The patients were introduced to a diabetes-appropriate diet containing oatmeal during a short hospital stay, then examined again four weeks later. On average, patients achieved a 40% reduction in insulin dosage – and maintained the reduction even after 4 weeks on their own at home.

Recommended Dietary Allowance (RDA) - the average daily dietary nutrient intake level sufficient to meet the nutrient requirement of nearly all - ~97% - healthy individuals in a particular life stage and gender group.
The process for setting the RDA depends on being able to set an Estimated Average Requirement (EAR). If an EAR cannot be set, no RDA will be set. The EAR is the daily intake value of a nutrient that is estimated to meet the nutrient requirement of half the healthy individuals in a life stage and gender group.
The RDA is set at the EAR plus twice the standard deviation (SD) if known (RDA = EAR + 2 SD). If data about variability in requirements are insufficient to calculate a standard deviation, a coefficient of variation for the EAR of 10% is ordinarily assumed (RDA = 1.2 x EAR).
The RDA for a nutrient is a value to be used as a goal for dietary intake by healthy individuals. The RDA is not intended to be used to assess the diets of either individuals or groups or to plan diets for groups.
