My guide to eating slightly healthier.
So this is a warning to everybody out there: this is not a diet based on any sort of super-scientific research, nor is this guaranteed to wield any sort of weight loss. It’s just some tricks and tips that I’ve picked up that I feel are important enough that everybody should at least attempt.
Stop drinking sodas. Drink water instead. This is the very first step I took 
before I was even trying to figure out what’s healthy and what’s not. Soda contains large amounts of sugar (or high fructose corn syrup), as well as tons of other little chemicals such as preservatives which just aren’t natural. The common trend in this list is this: if it’s made in a laboratory, don’t eat it. Diet Sodas are included in this, seeing as 99.9% of diet sodas contain Splenda/Aspartame instead of sugar, which some studies have shown has the potential to increase your risk of cancer. Trust me, you’ll feel so much better by the first week of doing this. Also water isn’t the only thing you can drink – some juices, such as blueberry juice, is absolutely amazing for you in moderation.
Switch to whole grain. This one’s also a little bit of a no brainer – switch to whole grain, if you can. In my opinion whole grain has a much better texture, and has tons of health benefits for you as well. You’ll also find that you can get whole grain in products you already love. Kraft Macaroni & Cheese, Poptarts, and those little fish crackers all are great examples of products that have the same taste that you know and love, but with the added health benefits of whole grain.
Stop eating traditional chips/”crisps”. There are a whole bunch of alternatives to the average “Lays” potato chips that everybody seems to buy lately. Lays themselves makes a baked alternative which you can find at basically any market. Some of my favorite chips are the famous Cape Cod Reduced Fat Potato Chips, which really cut out a ton of the fat content in their originals and compared to Lays, and they taste better, too. There are alternatives to your standard Market Basket branch corn chips as well. Instead of the regular corn chips, try finding “Good Food Should Taste Good” brand multigrain chips – they’re absolutely delicious, and much healthier than your average corn chip.
Change the way you consume dairy. Another good one. Today we see all too 
many people drinking whole milk, or eating american cheese with their meals. Switch to 1% of even fat-free milk, and maybe to provolone cheese instead of american. If you’re a cheese and crackers sort of guy, may I recommend that you switch your regular cheese with Cabot 50% or 75% Reduced Fat Sharp Cheddar. It’s amazing.
Switch to organic products wherever and whenever possible. Apple juice. Grapes. Milk. Cereal. Almost everything you can possibly think of has an organic version of it that isn’t riddled with chemicals made in a laboratory, and other things that you and I don’t even want to know about. I recommend just switching to organic wherever and whenever possible, if your budget will allow. It’s just better for you.
There are a whole bunch of little things you can do along with all of these as well, of course. Try exercising a bit more. Portion control is also very important.
