Excess protein itself doesn't cause a single disease but can worsen kidney issues, potentially leading to kidney stones, contributing to gout, and stressing the liver and kidneys, while very high intake can cause issues like protein poisoning (severe dehydration and electrolyte imbalance) and indirectly increase risks for heart disease and some cancers, with genetic conditions like Phenylketonuria (PKU) and protein-misfolding disorders like Amyloidosis being distinct protein-related issues.
Extra protein intake can also lead to elevated blood lipids and heart disease since many high-protein foods are high in total and saturated fat. Because it can tax the kidneys, extra protein intake poses an additional risk to people predisposed to kidney disease.
The condition is rare (affecting fewer than 4,000 people in the United States each year), but it can be fatal. Amyloidosis sometimes develops when a person has certain forms of cancer, such as multiple myeloma, Hodgkin's disease or familial Mediterranean fever (an intestinal disorder).
High dietary protein intake can cause intraglomerular hypertension, which may result in kidney hyperfiltration, glomerular injury, and proteinuria. It is possible that long-term high protein intake may lead to de novo CKD. The quality of dietary protein may also play a role in kidney health.
There are two primary syndromes associated with protein deficiencies: Kwashiorkor and Marasmus. Kwashiorkor affects millions of children worldwide.
Healthcare providers call amyloidosis a “protein misfolding disorder.” Instead of being neat, long chains that your body can break down, the fibrils get stuck in organs and cause problems. Causes of amyloidosis include: Gene changes (mutations).
Avoiding high-protein foods such as red meat and incorporating more plant-based protein sources like legumes and nuts can help in regulating protein levels. Additionally, maintaining adequate hydration supports kidney function, aiding in the elimination of excess proteins from the body.
Early warning signs of eating too much protein
Early signs of amyloidosis are often vague and can mimic other conditions, including extreme fatigue, unexplained weight loss, swelling in legs/ankles, shortness of breath, numbness/tingling (especially in hands/feet, potentially carpal tunnel syndrome), easy bruising (around eyes), and digestive issues like diarrhea, with the specific symptoms depending on which organs are affected. Because these symptoms are non-specific, diagnosis is challenging but a doctor may suspect it if symptoms persist or worsen, requiring a biopsy for confirmation.
Organ meats are high in protein and low in carbohydrates, but not all contain as much protein per 100 grams as muscle meat does. Liver and heart have the highest proportion of protein among the organ meats.
In the United States, AL amyloidosis is the most common type, with approximately 4,500 new cases diagnosed every year. It usually affects people from ages 50-80, although there are a few cases of people being diagnosed as early as their late 20s.
Diagnosing and treating proteinuria
Small amounts of protein in urine are normal, but your provider may refer you to a nephrologist if protein levels are too high. A nephrologist may order further tests to identify the underlying cause of proteinuria.
AA amyloidosis is also known as secondary amyloidosis or amyloid serum A protein. This amyloidosis type happens when you have high levels of inflammation in your body that boost the serum A protein levels in your bloodstream.
High blood protein levels are linked to several medical conditions and issues: Dehydration. Chronic (long-term) inflammation or inflammatory disorders. Viral infections such as hepatitis B, hepatitis C or HIV/AIDS.
Amyloidosis affects less than 250,000 people in the U.S., well under one-tenth of 1 percent of the population. If left untreated, AL amyloidosis can be fatal in six months. Hereditary or familial amyloidosis can be fatal in 2.5 to 3.5 years on average, if untreated.
High-Fat and High-Protein Foods
High-protein foods like steak and chicken can also disrupt sleep because they take a long time to break down, which is a problem at bedtime since your digestion slows by up to 50 percent when you sleep. (Your body faces a similar challenge if you dine on a large meal right before sleep.)
Red flag for amyloidosis cardiac involvement. Heart failure symptoms especially due to right ventricle involment. Family history of heart failure in hereditary form. Fatigue.
The TDI tracings shows the ''5-5-5'' sign (s' [systolic], e' [early diastolic], and a' [late (atrial) diastolic] tissue velocities are all <5 cm/s), which is seen in patients with more advanced cardiac amyloidosis. The dotted lines denote the 5 cm/s cut-off for systolic and diastolic tissue velocities.
The following team of doctors may be treating your amyloidosis: Cardiologist (heart) Hematologist (blood disorders) Neurologist (nervous system)
The hair will feel dry, brittle and stringy, because it won't have enough moisture to stretch and support elasticity. The hair will lose shine and look dull. You will have more frizz than normal, a wiry, stringy type of frizz. You may notice additional shedding, due to the hair breaking when brushing.
Depending on the cause, your provider may recommend:
Here are 12 surprising sources of protein:
When your kidneys have only mild damage and you have only small levels of protein in your urine, you will not notice any symptoms. When your kidneys have more severe damage and you have high levels of protein in your urine, you may start to notice symptoms such as: Foamy, frothy or bubbly urine.
The "2-hour protein rule" refers to the idea that consuming protein within about two hours after exercise is crucial for muscle repair and growth, often suggesting a 20-30g serving to kickstart the recovery process, though modern science shows muscles stay receptive to protein for longer (up to 24 hours). While getting protein in this post-workout window (sometimes called the "anabolic window") is beneficial, especially if training fasted, total daily protein intake and evenly spaced meals are generally considered more important for overall muscle health, with a broader window of 4-6 hours for optimal synthesis after workouts.
Stay away from processed meats. Pick nutrient-rich protein choices such as: Soy protein. Beans and other legumes such as lentils.
