Sodium

Sodium Chronic Disease Risk Reduction Level (CDRR) depends on age (US Dietary Guidelines for Americans 2020–2025)

Sodium plays a key role in:

Lowering high blood pressure lowers the risk of heart attack, stroke, heart failure and chronic kidney disease, and lowering sodium intake lowers the risk of osteoporosis and stomach cancer.
Set your target daily sodium intake based on guidance provided in the app and your preferences for weights of food (g or oz) and display of sodium content in foods and beverages (ie, %target/serving, mg/100g or mg/1oz, or %target/100g or %target/1oz).
Record food and beverage consumption using the barcode scanner, dictation or search, or by favoriting foods and using the serving sizes provided (which can be changed at any time). Tap the notepad to add notes.
Monitor daily and long-term progress, export data to share with healthcare providers, synchronize data with other First Line Medical Communications Ltd nutrient counter apps, and share data with Apple's HealthKit.
Add your own foods (a sodium/salt conversion tool is provided) and recipes and change serving sizes to personalize the app's 400-item database for you.
The app also provides nutritional information for many healthy foods and supports a healthy gut microbiome diet using color-coded type and icons as follows:

Plants that can be included as one of the 30 different types of plants per week recommended by experts for a healthy gut microbiome are in green type with a green leaf icon in the food popups. The most prebiotic plants (ie, those that are particularly beneficial for the gut microbiome) are in a darker green type.
Fermented foods that contain beneficial live microbes to become part of the gut microbiome (probiotics) are in gold type with a gold microbe icon in the food popups.
Foods that are likely to be ultra-processed (UPFs) — ie, contain ingredients not found in a home kitchen (eg, preservatives, flavorings, and emulsifiers) likely to harm the gut microbiome are in red type with a red warning triangle in the food popups. UPFs cause obesity for a variety of reasons and their harmful effect on the gut microbiome is linked to inflammation and many diseases including type 2 diabetes, high LDL "bad" cholesterol, cardiovascular disease, hypertension, non-alcoholic fatty liver disease, inflammatory diseases, cancer, depression, and neurodegenerative diseases such as Alzheimer's dementia and Parkinson's disease.
