An interesting article, published at Fitnesspal Blog, about some common foods in our diet that can be possibly causing problems if you eat them before exercise. Which type of foods are they?

Skip-These-5-Foods-If-Youre-Working-Out-Soon-752x472

We’ve all been there: You’re just gearing up to crush a workout, and then it strikes. “It” being the stomach cramping, the bathroom urgency, the wave of fatigue. If you’re exercising outside or in the middle of a fitness class, this gastrointestinal distress can be even more discouraging.

Although a sudden virus might be at play, it’s more likely that what you ate just before working out could be the culprit. “Exercise and digestion are mutually exclusive,” says Shawn Khodadadian, MD, of Manhattan Gastroenterology. “When you exercise, your body isn’t using its energy for digestion. It slows that process so it can divert as much blood as possible to your muscles and lungs.”

That means foods you digest just fine when not working out could cause you problems if you eat them pre-exercise. Certain foods can prompt heartburn, stomach ache or even vomiting, Khodadadian notes.

Here are some common food choices to avoid:

1. PROTEIN SHAKES & BARS

While protein is very helpful for post-workout recovery, it can be tough on your system if you have a shake right before working out. That’s because protein digests slowly, Khodadadian says. If you’re having a shake less than three hours before a workout, you could see some digestive blowback. The same goes for a high-protein bar…..

The fix: If you regularly rely on a protein boost right before working out, and tend to feel not-so-great while exercising, try having the shake or bar after exercising instead.

2. MILK

Many runners love their chocolate milk fix, but they’re careful to drink the beverage after a big run or a race. That’s because milk has high amounts of protein and fat, which take time to digest.

The fix: If you’re looking for a dairy-type boost in your pre-workout mix, consider whey protein mixed with filtered water instead — but even then, consume the drink at least a few hours before your workout.

3. HIGH-FIBER CEREAL

Loading up on a carb-rich choice like cereal is tempting before exercising, especially if you’re pressed for time. But, like protein, fiber digests slowly, and your workout can interfere with that process, Khodadadian notes.

The fix: As an alternative, try a food you can digest easily that’s high in carbs but low in fiber, such as oatmeal. That way, you can get the fuel you need without the GI issues. Consider adding even more of a carb boost with bananas or mangoes.

4. SPICY FOOD

Even if you regularly amp up your spice levels, you may have issues if you eat too much before working out. The slower digestive processes that happen when you begin exercising could leave that delicious taco sitting in your stomach, and that can prompt indiges…….
