Report issues with foods

With millions of food products on the global market, keeping our database complete and correct is a big job. We’re working on some major projects to improve our curation abilities, and today we’ve rolled out the first of these improvements. We’re making it easier to report issues with our foods so that our curation staff can review and amend any errors and omissions.

On the web version, if you open a public food in the food editor (on the Foods tab) you can select ‘Report Issue…’ from the food editor action menu:

Report Issue Menu Item

This will bring up a dialog where you can explain the issue and attache photographs of the label as evidence for our curation team to review.

Report Issue Screen

This new feature, along with some great back-end tools to streamline curation tasks, are part of our long term solution to keeping on top of the ever-changing food product landscape.

We’ll be rolling out this feature to our mobile apps in the near future as well.

With the help of our community, we intend to build and maintain the best and most accurate food and nutrition database on the market!

Important security announcement regarding the ‘Cloudbleed’ vulnerability.

Last night Google’s security team published details about a security bug in a leading cloud services provider, Cloudflare.

Cloudflare sits between web sites and users to optimize content delivery and provide protection from hackers and DDoS attacks. Cloudflare is used by over 4 million websites, including

While the practical risk to our users is considered extremely low (1 in every 3.3 million web requests potentially leaked memory from their system), we want to make sure you are aware that there was the potential for your passwords and session tokens to be leaked if you used cronometer while the vulnerability was active (September 22nd, 2016 — February 18th 2017).

As a precaution, we will be invalidating all session tokens generated during this window, which will result in many people getting logged out of the app. It is also advisable to change your password, as well as for any other sites you may have accounts with that were using Cloudflare (Fitbit, Uber, OkCupid, Yelp, and many more).

For more general information on the issue, this TechCrunch article has a good summary.

Again, to be clear, we believe there is practically little to no risk to our customers, and there’s no evidence any of our customers’ sessions were compromised,  but we are taking all necessary precautions. If you have any questions or concerns, please contact our support team at

Sugar Alcohols, Vitamin D study, and Supplements

Sugar Alcohols

We’ve now added support to track total Sugar Alcohols (polyols) in the carbohydrate breakdown. Please note we only currently have data for this in some of our whole foods database. By default they are not tracked as a target in your diary, but you can enable this on the Profile tab.

GrassrootsHealth Vitamin D Study

You can now join and link to an ongoing long-term study on Vitamin D.  Through them you can order your at-home vitamin D blood test kit and have your vitamin D serum levels measured every 6 months. Linking your cronometer account with their system will allow sharing your diary data with the researchers. They hope to learn more about how your diet, exercise, and supplementation affects your vitamin D serum levels. If you want to enroll, visit the Profile tab in cronometer and enroll in the Sharing section.

Retiring unused Foods & Recipes

If you’re like me, you have a lot of older custom foods and recipes you no longer use. We’ve added an item to the food editor’s menu to ‘Retire’ a custom food. Instead of entirely deleting the food (and all the associated servings that used it), a retired food is not deleted from the system, but will no longer appear in your food lists and searches.

Screen Shot 2016-03-23 at 11.17.36 AM

Your historical data using the retired food or recipe will remain unaffected.

Macro Tracking Changes, Ketogenic Mode, & Body Snapshots

Today we have a few changes to the dynamic macronutrients feature. These changes are on the web version only, but will be rolled out in the mobile apps as well in their next updates.

We’ve had the dynamic macronutrient targets feature for a long time, which lets you set and display preferred macronutrient ratio target. However, the macro targets have always been computed off of a fixed calorie target (the yellow bar).

Today, we are changing this to also be dynamically derived from your energy expenditure (calories burned) and your weight goal. This is more in line with what people expect, and the old behaviour has caused a lot of confusion for people.

If you stubbornly prefer it the old way, we can help you override it if you email our support.

ketomodeKetogenic Mode

Ketogenic diets are becoming extremely popular. We’ve added some specific improvements for people following a nutritional ketosis diet.

keto settingsIn the macronutrient settings, if you select the ‘Ketogenic’ option, now, instead of the previous fixed ratios, we dynamically calculate your maximum ketogenic protein and carbohydrate limits based on your lean body mass and exercise levels. Anything remaining, gets assigned to fats. We offer three ketogenic diet presets: Rigorous, Moderate, and Relaxed, as well as an option to choose custom values.

You can now hover your cursor over the macronutrient bars to see the top contributors to that macronutrient in your diary. This is especially helpful on a strict ketogenic diet where it can be critical to figure out what foods might be tipping you over your carbohydrate and protein limits.

In ketogenic mode, we also add some buttons next to the targets for easy logging of blood glucose and ketone measurements.

Body Snapshots

Under the trends tab we have added a new ‘Snapshots’ section where you can upload photos of your body recomposition progress. Each snapshot can store a caption and your body composition for the date of the photograph.

Please let us know what you think, and if you notice any bugs, we’ll be standing by to address them!

For more details on these features, see our User Manual.

What’s Up With Vitamin A?


What’s up with vitamin A and Cron-O-Meter? I have one lousy small carrot and I am at 278% of my daily requirement for vitamin A. Is that correct? And to add to it all, vitamin A is supposedly toxic at high doses. First, it is correct, and in this blog I will address what is going on and shed some light on what is up with vitamin A.

Carrots, spinach, kale, bell peppers, sweet potatoes, cantaloupe, apricots, broccoli, tomatoes, and asparagus are all excellent sources of vitamin A. Vitamin A will preserve and improve your eyesight and help you fight off viral infections. It is known as the “anti-viral vitamin”. It is also a fat-soluble vitamin and needs fat to dissolve it and transport it within the body. Deficiencies may be caused by a diet that is extremely low in fat.

There are two different types of vitamin A. The first type, preformed vitamin A (retinol), is found in meat, poultry, fish, and dairy products. The second type, provitamin A (carotenoids), is found in fruits, vegetables, and other plant-based products. The most common type of provitamin A in foods and dietary supplements is beta-carotene.   Preformed vitamin A and provitamin A is where the confusion comes in.

Toxicity can occur with excessive intakes of preformed vitamin A (retinol) and not necessarily with provitamin A (carotenoid) intake. The dosage levels that need to be obtained to cause toxicity are difficult to attain through food alone. Toxicity usually has been associated with prolonged supplement intake over a long period of time.

Symptoms of getting too much preformed vitamin A (retinol) can cause dizziness, nausea, headaches, coma, and even death according to the National Institute of Health (NIH).

Consuming high amounts of provitamin A can turn the skin yellow-orange in color, but this condition is harmless.

In Cron-O-Meter (CM) you can click on “vitamin A” and open a box that displays the daily recommended intakes (DRI), which are CM’s default settings. The range in the picture is for a fifty-year-old male.  These are also editable and you can put any range you desire into them.

Vitamin A

The DRI’s and tolerable upper limits (UL) for preformed vitamin A can be found on the site   There are no limits established for provitamin A (carotenoids, beta-carotene).

We get a lot of questions when one carrot reflects 278% of your daily value, but we here at Cron-O-Meter can’t tell you what amount to take or what ranges to use. That decision is left to you and your healthcare team. We hope this blog will help you understand why CM states what it does and what it means allowing you to be better informed and make the decision that is best for your health.

Live well!
