Fiber: A Spotlight on Soluble
The USDA Dietary Guidelines for Americans recommend adults consume about 30 grams of total fiber daily – at least 5 to 10 grams of that should come from soluble fiber sources. Soluble fiber can help to reduce the risk of heart disease and diabetes.
Soluble fiber lowers LDL cholesterol by forming a gel during digestion, which helps to trap and remove cholesterol from the body lowering blood levels. High levels of LDL cholesterol can accumulate along your vessel walls, this is called plaque and makes it harder for your body to pump blood to your organs.
Soluble fiber also causes food to move more slowly through the digestive tract. This supports a gradual release of sugar into our blood and helps to reduce blood sugar spikes.
Include More Soluble Fiber in your Diet:
Everyday foods can help you meet recommendations - the above example provides 8 grams soluble fiber.

Should You Track That?
There is pretty much an app for everything now. With booming research relating diet to health outcomes, nutrition-focused apps promise users a more detailed sense of their health through self-monitoring.
We know that nutrition is not one-size-fits-all. Diet recommendations should always be individualized. It’s important to understand that nutrition apps work similarly. What might be a great tool for one person may not be helpful to another.
The good news is there are a variety of options available. Some guide users in tracking macro– and micronutrients while others prompt users to track emotions related to food choices instead of calories. There are even apps specific to conditions such as eating disorders, diabetes, or pregnancy.
For data-driven, nutrient-focused folks: try Cronometer
For those seeking understanding around emotional eating patterns: try Am I Hungry?
For visual learners, curious about mindful eating without calorie emphasis: try Ate Food Journal
For those interested in support for disordered eating: try Rise Up and Recover (recommended as an adjunct to professional treatment)
Research indicates that while most nutrition apps can provide the user with data, they may lack the education and individualized considerations needed to promote true understanding and long-term improvement. If you’re interested in trying an app, it’s helpful to work with a dietitian (RD). The combination of an RD’s education and the app’s consistency is likely to be more beneficial than using an app alone.
