This is exactly what the DnaBand bracelet does. After installing it on your wrist, the bracelet checks the barcode on the food, compares it to the DNA stored by the user, and flashes red if the food is inappropriate and green if it is an option healthy.
And although the bracelet is only available in the UK at this time, DnaNudge startup co-founder Chris Toumazou is expected to expand soon to include Los Angeles.
The company uses a mini DNA test to determine the potential health risks based on genetic makeup by sending samples by mail or to its store, where the company takes a sample of your DNA by wiping the saliva and comparing genetic markers for four health conditions: diabetes, high blood pressure, high cholesterol, and obesity.
This data is transferred to the DnaBand bracelet which is a small camera that can be worn on your wrist and can scan the barcode and is priced at 120 pounds.
The bracelet analyzes the nutritional information sent via the barcode and compares it with your DNA, and flashes green if it matches your DNA or red if it does not.
The company’s goal is not to stop you from taking caffeine and salty candy immediately, but for example, the bracelet can encourage you to change the chocolate bar that contains a higher proportion of sugar to a little less.
The idea of handing over your DNA to a startup could be rejected, especially when other companies share the DNA with the government without notifying customers. This is why the DNA laboratory ensures that your DNA information is not kept because the samples are destroyed once the initial test is completed.
However, in case the worst happens and your data is hacked, what more hackers can get compared to any other business is your eating habits, according to Chris Toumazou, but they won’t know who owns those eating habits, your identity will remain unknown.
Currently, the startup has intellectual property rights over any portable technology – including a mobile phone – that can scan barcodes or images and use biomolecular information and lifestyle.
While it is possible for these companies to take the data and sell it to supermarkets or insurance companies, this could happen in the future.
There are still hurdles to overcome, as DnaNudge doesn’t have data for all foods yet, and despite deals with giants like Walmart, customers may end up spending £ 120 on a portable device but that doesn’t match. With nutritional information in their local stores.
