Low Protein Vegetables and Fruits

Hi,
My dad has been advised to have low protein diet.
So hereby sharing you the information i gathered.

For a vegetable to qualify as a low-protein source, it must contain 4g or less of protein.

Although the protein content of vegetables varies by type, most vegetables are considered low in protein. Green vegetables, such as lettuce, cabbage, bell pepper(Simla Mirch,Dhobli Mirchi) and asparagus(shatavari) provide only 1 to 2g of protein per serving. Orange vegetables, including carrots, sweet potatoes(Ratali) and squash(Lal Bhopala) also contain only 1 to 2g.
On the other hand, a few varieties of vegetables are protein-free, including celery(maatth), green onion and radishes.

Following should be avaoided.
Broccoli and spinach are exceptions, providing 4 and 5g per serving, respectively.
Green peas qualify as a good source of protein, providing more than 8g of protein
Dry beans are counted as good protein sources.
Mushrooms 3gms
Okra(Bhendi) 2gms
CORN 4gm

Fruits tend to be even lower in protein than vegetables and baked goods. Fruits low in protein include apples, apricots, blueberries, cranberries, raspberries, strawberries, grapefruit, grapes, mangos, oranges, nectarines, papayas, peaches, pears, pineapple, plantains, plums, pomegranates, rhubarb, tangerines and watermelon.

Baked Goods
Baked goods such as breads, cakes, cookies and crackers do not generally contain high amounts of protein. Most of these foods are energy dense foods, which means they contain few nutrients per calorie.
