Does Eating Ham Make You Poop? The Impact of Ham on Bowel Movements

As a deli meat lover ham sandwiches are one of my favorite quick and easy meals. The salty smoky flavor of sliced ham pairs perfectly with cheese, lettuce, tomato and other sandwich fillings. But occasionally when I eat a ham sandwich or ham-topped pizza, I notice it seems to make me poop shortly after. Is this just coincidence or does ham actually have a laxative effect on the bowels? I decided to dig into the science to find out if ham really makes you poop.

What is Ham?

Before examining ham’s impact on pooping, let’s start with what exactly ham is. Ham refers to meat from the hind leg of a pig that has been cured, smoked, or otherwise preserved. The curing process involves treating the raw pork with salt, nitrites, and sometimes sugar or syrup. This imparts ham’s iconic salty flavor, pink color and extends its shelf life.

Some common types of ham include:

  • Country ham – Heavily smoked and salt-cured, with robust flavor
  • Honey ham – Glazed with a sweet honey mixture
  • Prosciutto – Italian dry-cured ham
  • Black Forest ham – Smoked ham coated in herbs and spices
  • City ham – Mildly smoked ham sold cubed or sliced

In terms of nutrition a 3oz serving of ham contains about

  • 120 calories
  • 15g protein
  • 4g fat
  • 2g carbs
  • 1000mg sodium (40% DV)

Now let’s look at why this processed meat may contribute to post-meal bowel movements

Does Ham Have a Laxative Effect?

There are a few components of ham that help explain why it may stimulate pooping.

Sodium – Ham is very high in sodium, with over 1/3 of the daily value in a small serving. Consuming foods high in salt causes the body to retain more fluid to maintain homeostasis. This extra fluid softens and adds bulk to stool, speeding up transit time through the colon.

Nitrates – Many cured meats like ham contain nitrates and nitrites to prevent botulism and preserve the meat. In some sensitive people, nitrates may cause the stomach and intestines to relax, stimulating bowel movements.

Fat – Some types of ham like country ham can be high in fat. The body secretes more bile to digest dietary fat, which also has a laxative effect for some.

Histamine – Fermented ham contains elevated histamine levels, which may irritate the gut for those with sensitivities. This can trigger diarrhea or loose stools.

So while ham itself doesn’t contain much fiber or typical laxative components, the combination of sodium, nitrates, fat and histamine provide plausible mechanisms for it to stimulate pooping in some individuals.

Other High Sodium Foods That May Make You Poop

Ham is not the only food high in sodium that may have a laxative effect. Other salty foods like:

  • Cured meats – Salami, jerky, pepperoni, bacon
  • Pickles
  • Olives
  • Sauerkraut
  • Canned soup
  • Soy sauce
  • Salted nuts
  • Feta cheese
  • Frozen meals

Consuming a diet consistently high in sodium typically results in looser bowel movements and more frequent pooping. The amino acid glutamine helps the intestines absorb sodium to prevent dehydration. But when sodium is excessive, fluid imbalances occur, contributing to diarrhea.

Those with salt sensitivity or conditions like IBS may experience the laxative effect of sodium most strongly. But for many people, a high-sodium meal can quickly send them to the toilet.

Why Fatty and Oily Foods May Cause Urgency

In addition to sodium, high-fat foods like ham may also stimulate pooping due to their effects on digestive processes. Dietary fats cause more bile to be released, which acts as a natural laxative. The body also secretes more mucus to protect the intestines when digesting fatty foods, adding bulk and moisture to stools.

Greasy, oily, and deep fried foods tend to be the biggest culprits for urgent bowel movements. Some examples include:

  • Fast food like burgers, fries, fried chicken
  • Pizza
  • Chips and other fatty snack foods
  • Creamy salad dressings
  • Fatty cuts of pork and beef
  • Nuts and nut butters
  • Full-fat dairy products

For most healthy people, an occasional high-fat meal will not cause serious issues. But those prone to diarrhea or loose stool may find greasy foods quickly send them running to the bathroom.

Tips to Offset Ham’s Laxative Effects

If you love ham but want to avoid any unwanted laxative effects, here are some tips:

  • Opt for lower-sodium ham slices when possible
  • Drink extra fluids to replace those lost from sodium intake
  • Limit portion size to 1-2oz max per serving
  • Balance with non-starchy veggies like lettuce, cucumber, bell peppers
  • Avoid stacking high-fat ingredients like cheese, mayo, or creamy spreads
  • Pair with soluble fiber like oatmeal to absorb fluid in the colon
  • Take a probiotic supplement to promote healthy digestion
  • Stay well hydrated in general to maintain regularity

Moderating sodium and fat intake from ham while increasing fiber and fluid can help prevent disruptions to your normal bowel routine.

Health Benefits of Pooping After Meals

While no one likes running to the bathroom with urgency after they eat, there are some benefits to pooping more frequently:

  • Keeps bowels empty and regular
  • Promotes elimination of waste and toxins
  • Discourages constipation and straining
  • Provides a sense of lightness and relief
  • Can aid weight loss and management
  • Improves absorption of nutrients
  • Lowers risk of bowel issues like hemorrhoids or diverticulitis

So pooping after eating is not inherently problematic unless it becomes excessive and disruptive. For most people, some post-meal bowel stimulation can actually be beneficial.

Is Eating Ham Healthy Overall?

Despite its laxative effect, ham does provide some important nutrients including:

  • Protein – High quality source providing all essential amino acids for building and repairing muscle.

  • B Vitamins – Including niacin, riboflavin, B6 and B12 for energy metabolism and red blood cell production.

  • Iron – Needed for transporting oxygen in blood and regulating cell growth.

  • Zinc – Boosts immunity and facilitates DNA and cell repairs.

However, the high sodium, nitrates and fat mean ham is best enjoyed in moderation as part of a whole food diet. Choosing lower-sodium options when possible or pairing with plenty of veggies can allow you to get ham’s nutritional benefits while mitigating drawbacks.

Healthier Ways to Get Your Poop Going

If you don’t want to rely on ham’s laxative powers, there are healthier ways to promote regular bowel movements:

  • Stay hydrated – Drinking enough fluids softens stool and supports digestion. Aim for 8 cups of water daily.

  • Eat more fiber – Soluble and insoluble fiber feed gut bacteria and add bulk to stool. Include fruits, veggies, beans, nuts, seeds and whole grains.

  • Exercise – Physical activity accelerates transit through the colon and stimulates contractions to poop.

  • Take probiotics – Beneficial bacteria support digestion. Try kefir, kimchi, and supplements.

  • Manage stress – High stress inhibits healthy bowel function. Try yoga, meditation, and deep breathing.

Making smart dietary choices, exercising, reducing stress and supporting your microbiome can keep your poop on track without relying on ham sandwiches.

The Bottom Line

Does ham make you poop? For many people, yes – ham’s high sodium content, nitrates, fat, and histamine can stimulate bowel movements and cause urgency shortly after consuming. However, this laxative effect is not necessarily harmful, as regular bowel elimination provides benefits and prevents constipation. Those sensitive to sodium or fat may experience the pooping effect more pronouncedly though. Moderating portion sizes of ham while balancing with fiber-rich veggies and staying hydrated can allow you to minimize disruptions to your normal bathroom routine. While ham is tasty, it’s best enjoyed in sensible portions alongside other whole foods for optimal digestion.

Is ham good for constipation?

Foods that cause constipation may slow digestion and create hardened stools. To prevent constipation, avoid foods that cause you to become blocked up such as dairy, red meat, and foods that have been processed or fried.

Does ham digest easily?

There isn’t much agreement on how easily digestible ham is as a protein source. Some sources say it’s highly digestible, while others claim it’s inferior to most other meats and not easily digested. Store-bought ham, which is what most people use, contains a great deal of sodium, which isn’t good for people or dogs.
