1 Watermelon

"Getting adequate vitamin C may be tremendously advantageous for adults in their 70s," Manaker says. "Data reveals that patients who are at least 75 years old and are admitted to a geriatric unit who have low vitamin C levels are frailer than those who have acceptable vitamin C levels."

Other research, according to Manaker, demonstrates a link between dietary and circulatory vitamin C levels and measurements of skeletal muscle mass in middle-aged and older men and women. Studies published in the Journal of Nutrition reveal that dietary vitamin C intake may play a key role in preventing age-related muscle loss.

Watermelon, according to Manaker, is a natural source of vitamin C, making it an excellent diet for adults over the age of 70.

2 Broccoli

Broccoli is high in nutrients, including vitamin C, making it a healthy addition to your diet.

Broccoli's calcium and collagen work together to offer you strong bones. Broccoli contains vitamin K, which aids in blood clotting.

Broccoli also has anti-inflammatory and digestive properties. This bushy green vegetable's dietary fiber can aid with regularity, reduce constipation, and maintain a healthy digestive tract.

Furthermore, scientists discovered that the antioxidant activity of sulforaphane in broccoli aided in lowering inflammation markers in laboratory experiments, indicating that broccoli can help with inflammation, according to research published in the journal of Preventive Nutrition and Food Science.

3 Walnuts

"Walnuts are one of the healthiest foods for folks in their seventies," Manaker explains.

Healthy participants between the ages of 63 and 79 who ate around 1/2 cup of walnuts every day for two years had decreased LDL (bad) cholesterol levels, according to studies published in Circulation. Walnut consumption lowered the amount of total LDL particles by 4.3 percent and the number of small LDL particles by 6.1 percent, according to the study.

"These changes in LDL particle makeup and concentration are linked to a lower risk of cardiovascular disease," Manaker explains. "The decreases in LDL cholesterol among the walnut group differed by sex; men's LDL cholesterol reduced by 7.9%, while women's LDL cholesterol fell by 2.6 percent."

Walnuts, according to Manaker, are a good source of plant-based omega-3 alpha-linolenic acids, which are important for digestion, absorption, and energy production. Walnuts also contain plant-based proteins, fiber, antioxidants, and a variety of micronutrients that help with a variety of health issues.

"Walnuts can be used as a plant-based taco filler, a topping for oatmeal, or just on their own," she explains.

4 Pomegranite juice

"The antioxidants in pomegranate juice help battle free radicals, which are unstable molecules that can damage our systems over time," Manaker explains. "As we get older, free radicals become increasingly more dangerous. Throughout the year, your best offensive and defense is to fuel yourself with healthy meals, beverages, and antioxidants."

Manaker recommends POM Wonderful 100 percent Pomegranate Juice if you're seeking for a specific brand of juice. Every 8-ounce serving contains 700 milligrams of polyphenol antioxidants.

"People in their seventies should make it a point to incorporate in a balanced diet," she advises.

Stress and environmental contaminants are two more variables that might lead to an increase in free radicals. To keep your body in good shape, it's critical to strive to avoid these scenarios.
