To assess the adequacy of a vegetarian diet at old age, the dietary intake (assessed through dietary history with cross-check) of 44 apparently healthy lacto-(ovo-)vegetarians, aged 65-97 years, was evaluated. Adequacy was assessed by a comparison of nutrient intake with (Dutch) recommendations and by evaluating data on nutritional status. The results were also compared with data of elderly omnivores. In contrast to elderly omnivores, percentages of energy from protein (13%), fat (37%), and carbohydrates (50%) as well as P/S ratio (0.63) were close to or within the range of Dutch guidelines regarding a healthy diet (percentages of energy from protein, fat, and carbohydrates 10-15, 30-35, and 55%, respectively: P/S ratio 0.5-1.0). For most of the micronutrients studied intake was adequate, and nutrient density of the vegetarian diet was higher than of the omnivorous diet. However, the supply of zinc (average daily intake 8.5 and 7.6 mg for men and women, respectively), iron (because of lower bioavailability of nonheme iron), vitamin B12 (women only: intake 2.3 micrograms/day), and water (daily intake less than 1600 ml for 30% of the vegetarians) need special attention, considering the relatively high prevalence of a marginal status of these nutrients. In conclusion, a lacto-(ovo-)vegetarian diet can be adequate at old age, provided that it is carefully planned, especially with respect to the supply of iron, zinc, and vitamin B12.

Background: Growing evidence demonstrates that maternal nutrition is crucial for the health of the mother-to-be, and early life course of the offspring. However, for most micronutrients, guidelines are inconsistent. This Delphi study aimed to investigate the level of expert consensus on maternal nutrition and micronutrient needs during preconception, pregnancy and lactation.

This study's objective was to develop desirable, safe, and nutritious dairy-rich breakfasts and desserts for older adults while identifying the influence of comfort, nostalgia, and texture preferences. Participants (n = 81, mean age = 71 ± 7.3 years) evaluated two breakfast meals (meat-containing, vegetarian) and two desserts (chocolate, vanilla puddings) for acceptance; they also answered inquiries concerning texture preferences and reported their feelings of comfort and nostalgia experienced during evaluation.

Background: Dietary protein adequacy is crucial for muscle health in aging individuals, posing a particular challenge for vegetarian seniors. This randomized controlled trial (RCT) investigates the impacts of protein-enriched lacto-vegetarian soup supplementation on body composition, physical performance and muscle strength functional assessment as well as cardiometabolic and inflammatory biomarkers in older adults.
Methods: We enrolled 100 participants ≥65 years at risk for malnutrition (MNA-SF ≤ 11) and at risk for sarcopenia (SARC-F ≥4 or SARC-CalF ≥11) in this RCT.

Background: Knowledge about the diet quality among youth who follow different types of plant-based diets is essential to understand whether support is required to ensure a well-planned diet that meets their nutritional needs. This study aimed to investigate how food groups, macronutrient intake, and objective blood measures varied between Norwegian youth following different plant-based diets compared to omnivorous diet.
Methods: Cross-sectional design, with healthy 16-to-24-year-olds (n = 165) recruited from the Agder area in Norway, following a vegan, lacto-ovo-vegetarian, pescatarian, flexitarian or omnivore diet.
Can We Maintain Muscle Mass on a Plant-Based Diet?

Purpose Of Review: This review aims to determine whether muscle mass and function can be effectively maintained without relying on animal-based protein sources. We evaluate the quality, digestibility, and essential amino acid profiles of plant-based proteins to understand their potential in preventing and managing sarcopenia.
Recent Finding: Recent studies indicate that while animal-based proteins have traditionally been considered the gold standard for supporting muscle protein synthesis, certain plant-based protein blends, fortified with leucine or other essential amino acids, can produce comparable anabolic responses.
