Importance

In a proud Hispanic household, we use Birria as a common traditional cuisine during the holidays. Being away from family through college is difficult, and so making this meal allows me to feel comfortable during stressful times.

Ingredient Research

Here you can include a relevant fact to highlight

This meal is high in protein, mostly from the roast beef chuck and beef broth. It also contains a moderate amount of carbohydrates and fiber, mainly from the peppers, onion, tomatoes, and spices. The fat and saturated fat mainly come from the beef and vegetable oil. Sodium is mostly from the added salt, garlic paste, and beef broth.

Pathway Regulation

After Eating Birria Insulin ↑, glucagon ↓ Carbs → energy through glycolysis Extra glucose → glycogen storage Protein → tissue repair and protein synthesis Fat → stored or used for ATP Fasting pathways decrease, including ketogenesis and heavy fat breakdown

How do they interact

Pathway Interactions

Go Back

(Lindshield, 2018)

Key Enzymes

• Enzymes like hormone-sensitive lipase, CPT-I, PEP carboxykinase, and glucose-6-phosphatase decrease in activity because nutrients are available
• Breakdown pathways become less active, including:
• Glycogen breakdown
• Stored fat breakdown
• Gluconeogenesis

• Glycogen synthase becomes more active to store glucose as glycogen
• Glycolysis enzymes help use glucose for energy
• Glucokinase/hexokinase
• Phosphofructokinase
• Pyruvate kinase
• Insulin supports fat storage and lipid production

Inflammation Effects

• Chile peppers contain capsaicin, the main spicy compound in peppers
• At lower doses, capsaicin may have anti-inflammatory effects
• High amounts of capsaicin may cause discomfort
• Birria also includes ingredients like dried chiles, garlic, and spices
• compounds that can support lower inflammation
• Birria made with fatty beef can be high in saturated fat
• Possible temporary inflammatory effects if it is very high in fat

Cardiovascular Effects

Birria is usually made with beef, which may contain saturated fat Eating too much saturated fat can raise LDL cholesterol Higher LDL cholesterol is linked to increased risk of heart disease and stroke

Genetic Effects

Birria may affect genes related to inflammation and oxidative stress because dried chiles contain capsaicin, which may have antioxidant and anti-inflammatory effects. One birria meal likely has little epigenetic effect, but eating high-fat birria often could influence gene expression over time, especially genes connected to inflammation, metabolism, and heart health.

Reyes-Escogido et al., 2011) (American Heart Association, 2026)

Uncontrolled diabetes

With uncontrolled diabetes, insulin is too low or not working well, so glucose from birria’s carbohydrates stays high in the blood instead of moving efficiently into cells. The body may act like it is starving even after eating, causing the liver to keep making glucose while fat breakdown, beta-oxidation, and ketone production increase.

Protein and fat from birria may be used differently, with amino acids redirected toward glucose production and fatty acids increasing the risk of ketosis or diabetic ketoacidosis if diabetes is severely uncontrolled.

Birria can still be adjusted to better support health by using leaner meat,

Demographics and Health

Birria can be healthy in moderation, especially for a young adult female who is moderately active, because it provides protein, iron, zinc, energy, and about 12.9g of fiber, which is around 46% of a 28g daily fiber goal.

Birria can be made healthier by using leaner meat, skimming fat from the broth, watching portion sizes, and adding fiber-rich sides like beans, salsa, onions, cilantro, or vegetables.

Birria should not be eaten in large portions every day because depending on the meat, broth, and serving size, it can be high in saturated fat, sodium, and calories.

Sustainability

Birria’s sustainability depends on the ingredients and how often it is eaten, especially because it is usually made with beef.

Protection from Metabolic Syndrome

Tomatoes, onion, garlic, and dried chiles may help lower metabolic syndrome risk because they provide fiber, antioxidants, and anti-inflammatory compounds. Garlic and capsaicin from chili peppers may support cardiometabolic health by helping with blood glucose, blood pressure, cholesterol, fat oxidation, and insulin sensitivity. The most protective parts of the meal are the vegetables and spices because they add beneficial nutrients without adding much sugar or many extra carbohydrates.

Conclusion

Birria can be a meaningful example of how one meal affects the body in many different ways. I would not consider birria automatically unhealthy, but I would eat it in moderation and make small changes, like using leaner meat, skimming fat from the broth, and adding vegetables or beans.
