Are there well being advantages for a vegetarian eating regimen for older girls? Sure, science exhibits that vegetarian–even a vegan eating regimen for older girls could also be healthful and useful. The secret is creating an optimum consuming plan to satisfy your wants.
You’ve in all probability heard it earlier than, “A vegetarian eating regimen for older girls isn’t secure. And a vegan eating regimen for older girls is much more dangerous.” The idea that plant-based diets aren’t applicable for ladies as they age could be a frequent concern, even amongst well being care and vitamin professionals. But it hasn’t saved older girls—even celebrities equivalent to Michelle Pfeiffer and Christie Brinkley—from flocking to plant-based diets, equivalent to vegetarian and vegan diets. Based on a 2022 survey by Cornell College, about one in ten Individuals over the age of 18 considers themselves vegetarian or vegan. Girls aged 35 to 54 make up a rising seven p.c of that quantity, and girls older than 55 make up greater than two p.c, nevertheless it’s on the rise. And I see this on daily basis in my work as a plant-based dietitian. Fairly merely put, an increasing number of older girls are looking for out plant-based diets for well being advantages. However are these diets certainly healthful for ladies as they age?
It’s true that older girls have necessary vitamin considerations, equivalent to sustaining a wholesome weight, defending bones, and avoiding coronary heart illness. However that doesn’t imply a plant-based eating regimen is off limits. In truth, this type of consuming could also be useful in coping with these considerations. The Academy of Diet and Dietetics (The Academy) reported in its 2016 place assertion on vegetarian diets that appropriately deliberate a vegan and vegetarian eating regimen are healthful and nutritionally ample, and so they might present well being advantages within the therapy of sure illnesses throughout all phases of the life cycle.
“There’s no purpose in any respect why girls of any age can’t undertake a vegan or vegetarian eating regimen,” says Virginia Messina, MPH, RD, a plant-based vitamin professional who makes a speciality of diets for older girls and coauthor of Vegan for Her and By no means Too Late to Go Vegan. “Some nutrient wants change with age, however these wants could be met from plant meals,” Messina explains.
Potential Well being Advantages for Older Girls
Analysis helps the well being advantages of plant-based diets. Vegetarian dietary patterns have been linked with quite a few well being advantages, together with a decrease danger of ischemic coronary heart illness, hypertension, most cancers, and kind 2 diabetes, decrease ranges of LDL ldl cholesterol and blood strain, and decreased BMI. Within the landmark Adventist Well being Examine-2 (AHS-2), knowledge on completely different dietary patterns—vegan, vegetarian, pesco-vegetarian, semi-vegetarian, and non-vegetarian—had been analyzed from greater than 73,300 Seventh-day Adventist individuals in the USA and Canada. Based on Ella Haddad, DrPH, MS, RD, an affiliate professor within the division of vitamin at Loma Linda College Faculty of Public Well being, who evaluates knowledge within the AHS-2, “For coronary heart illness—the No. 1 killer in girls—the chance appears to be decrease amongst vegan and vegetarians, in accordance with the AHS-2.”
“In some circumstances, vegetarian girls might have nutrient intakes that decrease their danger for persistent illness,” says Messina, who additionally supplies vitamin sources on her web site, VeganforHer.com. Based on Reed Mangels, PhD, RD, LDN, a plant-based vitamin professional, creator, and vitamin advisor for The Vegetarian Useful resource Group, “By way of coronary heart well being, vegan diets are freed from ldl cholesterol, and relying on meals decisions, a vegan and vegetarian eating regimen could be low in saturated fat.”
In one other examine analyzing knowledge from each women and men enrolled within the AHS-2, researchers linked lacto-ovo vegetarian diets with a 9% discount in all-cause mortality and vegan diets with a 15% discount in contrast with nonvegetarian diets, though the findings had been extra strong for males than girls. Within the EPIC-Oxford examine, researchers discovered a 22% decrease danger of ischemic coronary heart illness amongst vegetarian adults (women and men mixed) in contrast with nonvegetarians.
One of many predominant benefits of a well-planned plant-based eating regimen is its wealthy nutrient profile, which can be much more necessary for older girls. “Vegetarians eat extra fiber and fewer saturated fats and have diets which can be richer in antioxidants, so there are some particular benefits to consuming this manner as we age,” Messina says.
It may be difficult for older girls to navigate and meet their dietary wants as power wants are likely to lower with ageing, which signifies that consuming a nutrient-dense eating regimen is very necessary, says Mangels. “Because of this in some methods, a whole-foods vegan or vegetarian eating regimen may very well make this simpler due to the various nutrient-dense meals which can be typically included. Girls can eat very effectively on a nutrient-dense vegan or vegetarian eating regimen with out feeling disadvantaged,” Mangels says. Plant-based diets, vegan diets particularly, are related to decrease BMI. A plant-based eating regimen might assist girls meet their dietary wants whereas avoiding weight achieve and its cascade of well being issues, which can happen because of greater physique fats.
Assembly Protein Wants
One of many best challenges for older girls on plant-based diets could also be ample protein consumption, particularly in mild of current suggestions to extend protein consumption whereas ageing. Decreases in whole physique protein can result in elevated frailty, impaired wound therapeutic, and decreased immune perform. A protein consumption reasonably higher than the Beneficial Dietary Allowance (RDA) of 0.8 g/kg of physique weight could also be indicated to reinforce muscle protein anabolism and reduce muscle mass loss. Based on the 2016 Place Paper on vegetarian vitamin for older adults, some proof suggests protein is used much less effectively with ageing, which can imply greater protein necessities.
“Protein is a nutrient that wants some consideration within the diets of all older individuals, because it’s so necessary for sustaining muscle and bone mass,” Messina says. “Vegetarians, and particularly vegans, might have considerably greater protein wants in comparison with individuals who eat meat. It’s by no means troublesome to get sufficient protein, however vegans do must put a little bit bit of additional emphasis on legumes, ensuring they devour at the least 4 servings per day. Some older vegans might do higher with even a little bit greater than that.”
“The AHS-2 discovered that these with greater protein consumption had higher bone density, irrespective of the place the protein got here from,” Haddad provides.
Messina means that it’s necessary to decide on protein-dense meals, notably these which can be excessive within the amino acid lysine. “These are legumes, equivalent to beans, soyfoods, and peanuts. Most older girls will want at the least 4 servings of those meals every day. It’s not onerous to devour that quantity, since a serving is simply 1/2 cup of beans, tofu, or soymilk or 2 tablespoons of peanut butter. But it surely does imply that some girls may have to emphasise legumes over grains,” she provides. Be taught extra about getting protein on a plant-based eating regimen right here.
Bone Safety, Calcium, and Vitamin D
One other necessary concern amongst older girls—vegetarians and nonvegetarians alike—is bone mass preservation (learn my weblog on bone well being for vegans right here). Osteoporosis impacts an estimated 200 million girls worldwide—and roughly one in three girls over age 50 will expertise osteoporosis fractures, in accordance with the Worldwide Osteoporosis Basis. Some dietary components, equivalent to calcium and vitamin D consumption, which usually are related to dairy meals, are necessary for bone well being and could also be a bit difficult to get in vegan diets. Nevertheless, plant-based diets could be wealthy in different key vitamins concerned in bone well being, equivalent to vitamin Okay and magnesium.
Are vegetarians—particularly vegans, who keep away from dairy merchandise altogether—at a higher danger of osteoporosis? “Older vegan girls must put some emphasis on calcium-rich meals, since calcium wants enhance with age,” Messina says. “And girls are at greater danger of bone loss.” Based on Mangels, some research level out the chance of decrease bone mineral density amongst vegetarians and vegan girls, however the proof is sophisticated.
Based on Mangels, there are solely a restricted variety of research on bone well being in older vegetarian and vegan girls. “Most are very small, and a number of other had topics the place each vegan and nonvegan topics had low intakes of calcium, under 400 mg/day. Though these research have a tendency to seek out decrease bone mineral density in vegans, I don’t assume there was a examine printed that has had an ample pattern measurement and that targeted on Western vegans and measured bone mineral density,” she explains.
In the case of bone well being, it could be simpler to have a look at an individual’s particular person nutrient consumption quite than generalizing a dietary sample. For instance, a poorly deliberate vegan eating regimen could be insufficient so far as protein, calcium, and vitamin D and put an older girl vulnerable to osteoporosis, simply as a nonvegetarian eating regimen can. To assist bone well being, Mangels recommends “ample protein—at the least assembly the RDA of 0.8 g/kg/day and probably going considerably greater, since greater protein intakes together with train have slowed the lack of muscle mass that happens with ageing. An consumption of 1 to 1.2 g/kg/day of protein appears affordable.” As for calcium, she recommends assembly the present RDA of 1,200 mg/day of calcium for ladies aged 51 and older.
To attain ample ranges of calcium and vitamin D, vegetarian girls can comply with the USDA MyPlate suggestions, which name for 3 servings of low-fat or fat-free milk, yogurt, and different dairy merchandise in addition to calcium-fortified meals and drinks. Vegan girls can change these dairy servings with different calcium-rich meals and drinks. “For vegans, calcium-rich meals are fortified plant milks, fortified juices, tofu made with calcium sulfate, and leafy greens equivalent to collards, turnip greens, kale, and bok choy,” Messina says.
Vitamin D is present in fortified plant milks, and vegan girls are inspired to get 10 to fifteen minutes of daylight publicity per day. “The AHS-2 confirmed that vitamin D standing was finest for those that lived in areas with extra sunshine; it was not as depending on eating regimen,” says Haddad, who stresses that getting ample vitamin D is necessary. Mangels suggests assembly the present RDA for vitamin D, which is 600 IU/day for ladies aged 51 to 70 and 800 IU/day for ladies older than 70.
Plant-Based mostly Omega-3 Fatty Acids
A physique of proof signifies that omega-3 fatty acids might have quite a few potential well being advantages, together with stopping coronary heart illness and stroke, aiding towards rheumatoid arthritis, and defending towards Alzheimer’s illness and most cancers. The consumption of marine omega-3s—EPA and DHA, which come primarily from fish—could also be low in vegetarians and vegans who keep away from fish altogether. Nevertheless, alpha-linolenic acid (ALA), a standard plant-based omega-3 fatty acid present in vegetable oils, walnuts, flaxseeds, and leafy greens, could be transformed to EPA and DHA within the physique, although at low ranges.
Whereas a number of research have discovered that EPA and DHA ranges are decrease in vegetarians and vegans than in nonvegetarians, Haddad stories that the AHS-2 revealed extra optimistic findings. “Omega-3 ranges—EPA, DHA, and ALA—within the physique had been good amongst vegetarians and vegans in AHS-2,” she says, including that she believes well being care professionals ought to encourage ample intakes of ALA, EPA, and DHA on this inhabitants, though she warns towards “going overboard” with them.
Whereas getting sufficient ALA could also be simple, because it’s discovered in lots of meals that seem on the everyday plant-based menu, EPA and DHA could also be extra elusive for vegetarians and vegans. Nevertheless, the rising availability of marine algae dietary supplements containing EPA and DHA has made it simpler to get these healthful fat. “The necessity for dietary supplements of DHA and EPA continues to be controversial. However conversion of ALA to those long-chain omega-3 fat could also be much less environment friendly in older individuals, so it could be a good suggestion to take a small each day complement offering 200 to 300 mg of DHA and EPA mixed,” Messina suggests.

Vitamin B12 Enhance
Simply as necessary as assembly the required consumption of omega-3s by eating regimen is sustaining ample ranges of vitamin B12. It performs a significant function in metabolism, crimson blood cell formation, central nervous system upkeep, and DNA creation. Vitamin B12 deficiency is critical, as it could lead to megaloblastic anemia, with signs that embody numbness within the arms, problem strolling, reminiscence loss, and disorientation.
However this important nutrient is discovered particularly in animal merchandise, equivalent to fish, meat, poultry, eggs, milk, and different dairy merchandise; it’s typically not present in plant meals. Although vitamin B12 is obtainable in fortified meals, it’s really useful that vegans complement their eating regimen with a each day vitamin B12 complement. Nevertheless, even nonvegetarian older girls must be involved about vitamin B12, as older adults might have impaired absorption of this nutrient and undergo from deficiency. Thus, the Institute of Medication recommends that each one adults over the age of fifty obtain most of their vitamin B12 by dietary supplements and fortified meals.
“Many older adults have problem with absorbing vitamin B12 from meat and dairy merchandise however are capable of soak up vitamin B12 from fortified meals and/or dietary supplements,” Mangels says.
Haddad stories encouraging findings from the AHS-2: “Most of our inhabitants was consuming meals that had been fortified with vitamin B12, taking a vitamin B12 complement, or each. I didn’t see that there was an enormous drawback with vitamin B12 deficiency amongst older girls on vegetarian or vegan diets.” Be taught extra about B12 on plant-based diets right here.
Discovering Steadiness
If you have a look at the proof on plant-based diets for older girls, vegetarian and vegan diets can present well being advantages or potential dangers, however this is determined by how applicable and effectively deliberate the eating regimen is. As with all eating regimen sample, it’s attainable to skip key vitamins, equivalent to calcium and vitamin D which can be important for well being, or overload on unhealthful vitamins equivalent to refined carbohydrates and sodium, which can be detrimental to well being. Nevertheless, a balanced plant-based eating regimen—wealthy in legumes, complete grains, greens, fruits, nuts, seeds, and healthful fat—provides the entire meals which can be linked to optimum well being. “It truly is necessary for postmenopausal girls to eat a really nutrient-dense eating regimen by together with loads of greens in meals and limiting ‘discretionary’ energy from sweets, snack meals, and alcohol,” says Messina. “It doesn’t imply you possibly can by no means have these meals, however placing the emphasis on complete plant meals turns into more and more necessary. And together with loads of train in your routine will assist you to devour extra energy, which in flip helps with assembly nutrient wants,” she says.
