Digestive Process

Fat Digestion

Fats don't just dissolve in water - they need a complex dance of bile, enzymes, and transport systems to get from your food into your cells. When this process fails, you miss out on essential fatty acids and fat-soluble vitamins.

Why Fat Digestion Matters

Cell Membranes

Every cell in your body is wrapped in a fat membrane. Poor fat digestion = poor cell function.

Hormone Production

Cholesterol from fats is the building block for all steroid hormones.

Brain Health

Your brain is 60% fat. It needs constant supply of fatty acids.

Fat-Soluble Vitamins

Vitamins A, D, E, K all require fat for absorption. No fat digestion = deficiency.

Energy Storage

Fats provide 9 calories per gram - your most efficient fuel storage.

Inflammation Control

Essential fatty acids regulate inflammatory responses throughout the body.

The Fat Digestion Process

1

Mouth & Stomach

Lingual lipase starts breakdown. Churning creates smaller fat droplets. Not much absorption here.

2

Bile Emulsification

Gallbladder releases bile. Bile salts break fat into tiny droplets (micelles). Critical step.

3

Pancreatic Lipase

Pancreas releases lipase enzyme. Breaks triglycerides into fatty acids and glycerol.

4

Absorption & Transport

Small intestine absorbs fats. Packaged into chylomicrons. Travel through lymph system to blood.

Signs of Poor Fat Digestion

Greasy, Floating Stools

Steatorrhea - undigested fat makes stools float, pale, and foul-smelling.

Bloating After Fatty Meals

Nausea, discomfort, or feeling heavy after eating fats.

Vitamin Deficiencies

Low vitamin D, A, E, K despite supplementation. They need fat for absorption.

Dry Skin & Hair

Essential fatty acids keep skin moisturized. Poor absorption = dry, flaky skin.

Hormone Imbalances

Low cholesterol absorption impacts steroid hormone production.

Brain Fog

Brain needs DHA and other fats. Poor digestion starves the brain.

What Impairs Fat Digestion

Low Bile Production

Liver issues, low-fat diets, or gallbladder removal reduce bile availability

Pancreatic Insufficiency

Low lipase enzyme production. Common in chronic pancreatitis, cystic fibrosis

SIBO

Bacteria in small intestine interfere with fat absorption

Celiac/Crohn's

Damaged intestinal lining can't absorb fats properly

Supporting Fat Digestion

Ox Bile Supplements

Provides bile salts directly. Essential if you've had gallbladder removed.

Digestive Enzymes

Lipase-containing enzymes help break down fats. Take with fatty meals.

Bitter Foods

Arugula, dandelion, artichoke stimulate natural bile release.

Apple Cider Vinegar

Stimulates digestive secretions. 1 tbsp in water before meals.

Don't Drink With Meals

Too much liquid dilutes digestive enzymes and bile.

Eat Fats Regularly

Low-fat diets cause bile to get thick and sluggish. Use it or lose it.

TUDCA

Bile acid supplement that supports bile flow and liver health.

Chew Thoroughly

Digestion starts in the mouth. Chewing signals the rest of the system.

Fix Gut Issues First

Address SIBO, leaky gut, or inflammation before expecting good absorption.

Types of Dietary Fats

Saturated Fats

Solid at room temp. Coconut oil, butter, animal fats. Stable for cooking. Not the villain they were made out to be.

Monounsaturated Fats

Olive oil, avocado, nuts. Generally considered heart-healthy. Good for medium-heat cooking.

Polyunsaturated Fats (Omega-3, Omega-6)

Essential - body can't make them. Fish, flax, walnuts (omega-3). Seed oils (omega-6). Balance matters.

Trans Fats

Artificially hydrogenated oils. Genuinely harmful. Avoid completely. Found in processed foods, margarine.
