Are you planning any road trips for any upcoming Spring Breaks? When you're on the road, it may seem like healthy food is difficult to find and that you're doomed to eat junk food until you reach your destination. But that doesn't have to be the case; you can find healthy foods while you're traveling if you know where to look.

Many convenience stores offer fresh fruit (you just need to search beyond the greasy chips and candy bars that are usually displayed prominently). You might want to pack a small cooler with fresh snacks and beverages that you have at home. This also saves you money since many things at the convenience stores are a little more expensive than what you already bought at the grocery store. Here are some more of my tips for healthy eating when you travel.

Astaxanthin is a substance found in salmon, trout and shellfish. It's related to vitamin A, beta carotene and lutein, so it should act like an antioxidant and maybe it's one reason why eating fish is good for you.

It's also appearing on websites and store shelves as a dietery supplement, usually accompanied by the statements that it's good for your vision and helps your heart. But is that really true? I took a look at the studies (the few that there are) and it may not live up to the hype. Stick with the fish.

Food and dietary supplement manufacturers can make certain health claims on product labels. Some of those claims can be kind of tricky - don't be fooled by food label claims. Read: Don't Let Tricky Food Label Claims Fool You

Raspberry ketone is an aromatic compound found in red raspberries. It's extracted and used in perfumes and cosmetics and it's also used as a flavoring agent in some fruit-flavored foods. Apparently now it's being touted as a semi-magical weight loss aid. But does it work? Who knows - I can't find any clinical studies for it.

There are some studies on mice that were given raspberry ketone and it appeared to prevent weight gain when the little rodents were fed high-fat diets. Apparently the anti-obesity effects were due to stimulation of lipolysis (which is how the body breaks down fat in fat cells called adipocytes) in both regular fat tissue and brown fat tissue. It also suppressed release of pancreatic lipase, a digestive enzyme needed to break down dietary fats so they can be absorbed through the small intestinal wall.

But this research was done on mice. We're humans, not rodents. We have different physiology and different emotional reasons for eating (or not eating) fats and other foods. So just because mice didn't get fat while being given raspberry ketone doesn't mean it will work the same way in humans. To know if raspberry ketone can work in humans requires clinical research and I can't find any research on people.

So will it hurt you to take raspberry ketone supplements? Probably not. Will it help you lose weight? I don't know, but I doubt it. More than likely it will just make your wallet a little lighter.
