In one sentence, describe what the following article is about:

A few studies have recently suggested that increasing the amount of lycopene and astaxanthin in your diet can actually help to protect you against sunburn. Lycopene is found in high concentration in tomatoes, particularly in tomatoes that have been cooked or in tomato products. Astaxanthin is found in algae, so it might be a bit more difficult to get into your diet. However, you can dine on animals that eat algae, like salmon and shrimp. The research on the sun protection offered by lycopene and astaxanthin are optimistic, but not 100% proven. Even if you start eating tomatoes and shrimp at every meal, you should still use a second form of sun protection. If you want to take the guesswork out of your sun protection, download a mobile app like Sunvisor. With Sunvisor, you can check your UV exposure risk, set countdowns to apply more sunscreen, and get an alert when you’ve been exposed beyond safe levels. It’s easy to start having fun outside and lose track of time, so apps like Sunvisor can keep track of things for you. It’s no surprise that in the era of the FitBit and the Apple Watch, there’s also a gadget for your wrist that can help keep you safe in the sun. There are several, in fact! Some are high tech, and some are simply wearable reminders to be safe and thoroughly protect yourself while outdoors.  One of the more high-tech options is the JUNE by NetAtmo. It syncs with an iPhone app to track your UV exposure and give you personalized suggestions to protect yourself. It is sold for about $50.00. For a cheaper, no nonsense option, you can get a simple UV color-changing wristband for $2.50. When it turns purple, it means you’re getting some strong rays and should take precautions to protect your skin.

Summary:
Eat strategically. Download a sun-smart phone app. Wear a UV-tracking bracelet.
