Red grapes
The color in red grapes comes from several flavonoids. These are good for your heart, because they prevent oxidation and reduce the chance of blood clots. One flavonoid in grapes, resveratrol, may boost production of nitric oxide, which increases muscle relaxation in blood vessels for better blood flow. Flavonoids also help protect you from cancer and prevent inflammation.
Choose those with red or purple skin grapes for the highest flavonoid content. Eat grapes as a snack. When frozen, they make a good thirst-quencher for those on a fluid-restricted diet. Add grapes to fruit or chicken salad. Or drink grape juice.
Strawberries
Strawberries may be small in size, but they are big in benefits! This delicious red fruit is a powerhouse of vitamins, antioxidants and fiber. Strawberries are known for heart protection, as well as anti-cancer and anti-inflammation properties. Toss them in a salad or even eat them plain for a healthy treat!
Cranberries
Cranberries are great for preventing urinary tract infections, because they make urine more acidic and help keep bacteria from attaching to the inside of the bladder. They’ve also been shown to protect against cancer and heart disease.
Although we think of cranberries as a holiday side dish, cranberry juice can be enjoyed daily for added nutrition. Or toss a handful of dried cranberries into your cereal or salad.
Egg whites
Did you know that egg whites are pure protein? They provide the highest quality protein there is, along with all of the essential amino acids. If you’re on the kidney diet, it’s good to note that egg whites have less phosphorus than other protein sources, such as egg yolks or meats.
Use egg whites for omelets or egg white sandwiches. You can also add them to smoothies or shakes. Hard boil eggs and use the whites to use in tuna or green salads.
Spinach
This leafy green vegetable is high in vitamins A, C, K and folate. The beta-carotene found in spinach is important for boosting your immune system health and protecting your vision. It is also a good source of magnesium. Instead of lettuce in your salad, try spinach. You can also easily incorporate spinach into your diet by making a simple side dish of steamed spinach, spiced up with garlic and olive oil.
Onion
Another popular food used for seasoning is the onion. Onion is full of flavonoids, particularly quercetin. Flavonoids are natural chemicals that prevent the deposit of fatty material in blood vessels and add pigmentation (color) to plants. Quercetin is a powerful antioxidant that is believed to help reduce heart disease and protect against many forms of cancer. It also has anti-inflammatory properties.
Low in potassium, onions are not only kidney-friendly; they also contain chromium, a mineral that assists your body with the metabolism of fats, proteins and carbohydrates.
Sweet Potatoes
These super spuds are packed with beta-carotene and are an excellent source of vitamins A and C. Sweet potatoes are also a good source of vitamin B-6 and potassium. One medium (5-inch long) sweet potato contains 112 calories and nearly 4 grams of fiber, according to the USDA National Nutrient Database. You can eat them mashed or even make your own oven-baked fries.
