1. Bread
You probably didn’t expect to see this one on the list. Bread is a staple in most households and can be packed with essential nutrients like folate, iron and fiber. While white bread can spike your blood sugar levels and doesn’t offer much nutritional value aside from carbohydrates (unless it’s enriched white bread, which is fortified with vitamins and minerals like thiamine (B1), riboflavin (B2) and niacin (B3) to replace the nutrients lost during its processing), its whole grain counterpart has additional fiber and nutrients and can help manage blood pressure while lowering your risk of diabetes and heart disease, according to Mayo Clinic. Consuming whole grains instead of refined grains is also linked to lower cholesterol and insulin levels.
2. Oats
Oats are one of my favorite foods on this list. They’re versatile, relatively easy to use and inexpensive. When we look at their nutritional offering, oats pack a punch. According to the US Department of Agriculture, oats are loaded with complex carbohydrates, fiber and essential vitamins and minerals like B1, B3, B5, B6, folate and iron. Oats are also a whole grain, and a meta-analysis found that the highest whole-grain intakes were significantly associated with a 21% reduced risk of heart disease compared to those with the lowest intake. Another meta-analysis, including studies that followed people with type 2 diabetes, found that oat intake significantly reduced blood sugar spikes after eating a meal. Opt for steel-cut or rolled oats to reap the most benefits, as instant oatmeal is more processed and has a slightly higher glycemic index.
