Women's Nutrition Needs Aren't Static

Williamson Health’s Melanie Parnell, RD, LDN, Shares Practical Tips to Stay Healthy Through Every Life Stage

Nutritional needs aren’t one-size-fits-all — especially for women, whose bodies change significantly across life stages. 

“Our bodies are different from men’s, so we have different nutritional needs,” said Melanie Parnell, a registered dietitian with Williamson Health. “Women’s bodies are designed to build another human, so we have a little more fat, a little less muscle and different hormonal needs.” 

Parnell, who teaches in Williamson Health’s diabetes prevention program and works as an outpatient dietitian, offered a few tips to help women make healthier nutritional choices. 

Understand that nutritional needs evolve with age. 

From adolescence to menopause, women’s bodies undergo many transitions. As women move through these life stages, their nutritional needs may need adjustment. 

“In adolescence, our bones do a lot of growing, so it’s important to work on bone health and density then,” Parnell said. “This starts around ages ten to fourteen, depending on when women begin puberty, and continues into early adulthood.” 

She recommends calcium- and vitamin D-rich foods like dairy, leafy greens and calcium-fortified foods, along with proteins such as meat, poultry and fish to support bone strength. Calcium remains important throughout life, especially during breastfeeding and after menopause.

“As we get older, our bone remineralization doesn’t keep up with our bone loss, and women often start to experience bone deficits,” Parnell said. “It also coincides with a time in our lives when we tend to become more sedentary.” 

In addition to a healthy diet, weight-bearing exercise — such as walking, jogging or weight lifting — helps maintain bone strength and muscle mass as women age.

Pay attention to common dietary deficiencies. 

Iron, calcium and vitamin D deficiencies are common among women, Parnell said. Physiological changes during menstruation, pregnancy, perimenopause and menopause can make women more prone to these deficiencies.

“If women aren’t getting enough calcium during pregnancy, the body will draw calcium from the mother’s bones to support the baby, and we can’t get that calcium back in easily,” Parnell said. 

A diet rich in lean meats, leafy greens and dairy can help maintain nutrient levels. Supplements may be needed in certain stages, but should always be guided by a physician.

Focus on balance.

In her conversations with women about nutrition, Parnell has uncovered several misconceptions about healthy diets. 

“I see a lot of extremes,” Parnell said. “Some women completely slash carbs out of their diets. There’s a lot of skipping meals and inconsistency around how or what they eat. Others try to take every diet plan out there and combine them all.” 

Rather than resorting to extremes, she suggested focusing on a balanced diet filled with whole foods, healthy proteins, calcium-rich dairy, fiber, whole grains and healthy fats, while limiting sugar, sodium and saturated fats. Supplements can help with deficiencies, but “food is better,” Parnell said.

Healthy nutrition takes planning and prioritizing. 

Eating well doesn’t always require a complete diet overhaul. Small, consistent changes add up.

“It doesn’t have to be hard, but you do need a strategy for success,” Parnell said. “Focus on what you’re doing well, then plan and prioritize small changes you can make.” 

Above all, she advised, give yourself some grace and strive for consistency, not perfection.
