Eating a low-protein diet is necessary for some people who have certain genetic conditions or kidney disorders. While low-protein diets can seem very restrictive, there are still many delicious plant-based options to choose from. This guide will provide an overview of low-protein foods as well as tips for following this type of diet.
What is Considered Low Protein?
The amount of protein that is considered “low” can vary based on individual health needs. However, most low-protein diets aim to restrict protein intake to 10-40 grams per day. Foods are considered low protein if they have less than 5 grams of protein per serving. People following low-protein diets need to focus on limiting both the obvious sources of protein like meats, eggs, and dairy as well as hidden sources like beans, nuts, and whole grains.
Benefits of a Low Protein Diet
There are a few key health conditions where a low protein diet is beneficial:
Phenylketonuria (PKU)
PKU is a genetic disorder where the body cannot properly metabolize the amino acid phenylalanine which is found in protein. Following a lifelong low protein diet can help prevent intellectual disabilities and other symptoms.
Chronic Kidney Disease
Reducing protein intake can help take the strain off damaged kidneys. This type of diet is often recommended for people with chronic kidney disease.
Maple Syrup Urine Disease
This inherited disorder makes it difficult for the body to process certain amino acids found in protein. A specialized low protein diet is needed to manage symptoms.
Under the supervision of a doctor or dietitian, a low protein diet can greatly improve health for people with these conditions.
Foods to Avoid on a Low Protein Diet
When following a low protein diet, many common foods need to be eliminated or strictly limited:
- Meat including beef, pork, chicken, turkey, lamb, veal, etc.
- Fish and seafood
- Eggs
- Dairy products like milk, cheese, yogurt, ice cream
- Legumes including beans, lentils, soybeans, chickpeas, peas
- Nuts and seeds
- Whole grains like wheat, oats, quinoa, rice
These foods are high in protein and off-limits when adhering to a low protein meal plan. People following this diet should also limit processed snack foods which can contain hidden sources of protein. Reading nutrition labels carefully is essential.
Low Protein Food Options
While low protein diets do restrict many common foods, there are still plenty of delicious plant-based options to create satisfying meals:
Fruits and Vegetables
Most fruits and vegetables are naturally low in protein. Focus on incorporating a rainbow of produce like berries, citrus fruits, leafy greens, carrots, sweet potatoes, peppers, cucumbers, tomatoes, and squash. One exception is avocados – they are higher in protein than other fruits.
Grains and Starches
Swapping out high protein whole grains for lower protein options can provide carbohydrates and fiber. Some examples include white rice, corn grits, popcorn, wheat-free oats, and tapioca. Starchy vegetables like white potatoes and corn can also be incorporated.
Oils and Condiments
Cooking with plant-based oils like olive oil and avocado oil can add flavor. Herbs, spices, vinegar, mustards, and lemon juice can provide an extra taste. Butter and bacon fat are high in protein and should be avoided.
Beverages
Water, seltzer, juice, soda, coffee, and tea are low protein options. Those following a PKU diet will also need to monitor high-protein drinks like soy milk, almond milk, and protein shakes.
Sweets and Desserts
Sugary foods made without protein sources are permitted in moderation. Examples include fruit sorbet, ginger cookies, jelly candies, marshmallows, and some ice pops. Always check labels since protein can sneak into baked goods.
Sample Menu for a Low Protein Day
Here is an example of what a tasty low protein menu could look like:
Breakfast:
- Scrambled eggs made with egg substitute, oven-roasted potatoes, sliced melon
- Oatmeal made with wheat-free oats, blueberries, cinnamon
Lunch:
- Taco salad made with corn tortilla chips, lettuce, diced tomatoes, avocado

Dessert:

Tips for Following a Low Protein Diet
It takes careful planning to meet nutritional needs on a low protein diet. Here are some tips for making it more manageable:
- Work with a doctor or dietitian to create a customized meal plan
- Take a daily protein-free multivitamin to fill any nutritional gaps
- Cook in bulk and freeze meal-sized portions for quick options during the week
- Always have safe low protein snacks on hand like fruit, popcorn, or pretzels
- Get creative with seasonings and spices to keep food interesting
- Be vigilant about reading nutrition labels for hidden protein sources
While limiting protein takes effort, there are still many delicious plant-focused dishes to enjoy. With proper planning, people can thrive on a low protein diet.
Conclusion
Low protein diets are medically necessary for people with certain genetic disorders like PKU as well as those with kidney disease. Foods like meat, eggs, dairy, and legumes are restricted, but fruits, vegetables, grains, and fats can still be enjoyed. Working with a healthcare provider to create a personalized meal plan based on specific protein needs is key for meeting nutritional requirements. With commitment and creativity in the kitchen, it is possible to achieve good health on a low protein diet.
