Omega-3 fatty acids are found in fish, canola oil, soy oil, walnuts, ground flaxseed and soybeans. Vegetarian diets that do not include fish may be low in two types of omega-3 fatty acids called DHA and EPA. Some evidence suggests that taking in EPA and DHA omega-3 fatty acids may lower the risk for heart disease.
Foods to minimize
These vegetarian dishes, along with salata (salad), are commonly served during Lent. The most widely available (and nutritious) food for early human populations was likely leafy greens, sweet grasses, nuts, seeds, tubers, berries, roots, fruit, and pulses. A small number of calories from insects, wild animals, and fish also rounded out many traditional human diets. In fact, anthropologists largely agree that the bulk of human calories over the course of history have come from plant-based sources. The under 35s are the leading age group in terms of diet changes, and 87% of these young people are worried about the environment.

When ingesting large doses unimeal app reviews of supplemental B12, about 1% of the dose is absorbed by passive diffusion across the intestinal tract [216]. Daily needs can be adequately met in non-pregnant, non-lactating people by consuming a 500 µg B12 supplement at least three times a week. Vitamin B12 is well absorbed from either sub-lingual or chewable tablets. Phytates in cereals and legumes lower absorption of zinc, but leavening, soaking, fermenting, or sprouting reduces the phytate levels and makes zinc more bioavailable [281]. Sulfur-containing amino acids and organic acids in a variety of plant foods will also enhance zinc absorption [279,282].

Based on the studies’ reference list and other studies of this particular group [30], however, one may assume that the dietary intervention was technically vegan. Nevertheless, all 4 aforementioned articles were not considered in the final dietary group assignment (see below and Fig. 3). Articles were included if they reported a plant-based dietary intervention in human subjects, irrespective of age, gender, race, or ethnicity. To be eligible, articles had to include the term “plant-based diet” or a synonymous term (e.g. “plant-based dietary intervention”, etc.) in the abstract, the introduction or the methods section. We considered only interventions with a minimum duration of 1 week. Studies were included irrespective of their outcome, as we focused solely on the description of each intervention.

This serves an indirect indicator that their diet contained substantial amounts of animal products, because strict plant-based diets are usually much lower in cholesterol [35]. The authors found that weight loss was equal with both diets and concluded in their abstract that weight loss “occurred equally with the meat-based and plant-based diet” [34]. Individuals following vegetarian diets generally consume more than adequate protein, particularly in western countries, although intakes are typically lower than those of omnivores [120]. Furthermore, as long as a variety of protein-rich foods are consumed, vegetarian diets are able to provide all of the indispensable amino acids [120,326]. While there is no need for different protein foods to be combined in one meal, a variety of plant foods should be included each day [326]. Most plant foods contain some protein, with the best sources being legumes, soy foods (including fortified soy milk, tofu, and tempeh), nuts, and seeds.

Be sure to meet with your primary care doctor or a dietitian at least once a year to have your labs measured to assess for any deficiency. In the UK, younger generations are the main driver of change, influenced by concerns about animal welfare, health, and climate change. Business Expert has compiled a series of infographics based on various reports about the plant-based market. The images show the rapid growth of the vegan economy and the effect this will have on global business in the coming decades. Vegetarians also do not eat products containing gelatin or rennin (an enzyme found in calf’s stomachs that is used to produce many cheeses). This section collects any data citations, data availability statements, or supplementary materials included in this article.
Vegan children appear learnmuscles.com/blog/2025/11/25/unimeal-weight-loss-app-review-12-reasons-to-trust/ to have lower intakes of total and saturated fat and cholesterol compared to non-vegan children [211]. A low-fat vegan diet has effectively treated children with obesity and elevated blood pressure [212]. Over 70% of adults in the U.S. are overweight or obese [86], and trends show that overweight and obesity are increasing worldwide [87]. Vegans typically have the lowest BMI or lowest prevalence of overweight or obesity in studies that compare multiple dietary patterns, including vegetarians and omnivores [88,92]. Gogga et al. noted differences in percent body fat between vegans, lacto-ovo-vegetarians, and omnivores, even though all group BMI values were within the normal range [93]. Interventions using vegan [94,95,96,97,98,99], vegetarian [97,100], or whole-food plant-based dietary [101] treatments have been found to lower BMI, weight, or fat-mass compared to subjects on a meat-based diet.
The Vegan Diet
Avoiding animal foods can shortchange you on a few nutrients, like protein, calcium, omega-3 fatty acids, zinc, vitamin B12, and vitamin D. Omega-3 fatty acids keep your cells healthy and protect your heart by shielding against heart disease and stroke. Traditional diets, such as the Mediterranean diet, tend to focus on more whole, minimally processed plant foods. Known for its well-documented health benefits, the Mediterranean diet is essentially a form of plant-based eating. Most of the diet consists of whole grains, vegetables, fruits, nuts, seeds, and pulses (the edible seeds of legumes such as lentils, beans, and peas).
It benefits a number of health conditions
Absorption can be as low as 2–3% in people with good iron stores but as high as 14–23% in people with low iron stores [268]. Adding more plant-based foods to your diet can sometimes cause gas or other gastrointestinal issues due to the increase in fiber. If that’s the case for you, focus on adding one additional serving of plant-based food per day every week.

- Many researchers use this term interchangeably with a vegan diet, as 50% of the included studies completely excluded animal products.
- A template including nine items that primarily focuses on the description of the dietary intervention itself is provided below (Fig. 4).
- We considered only interventions with a minimum duration of 1 week.
- People who follow plant-based diets may have smaller environmental footprints.
- Calcium sources for children and adolescents include fortified plant-based milks, green leafy vegetables, and dairy products.
- People are concerned about issues such as their health, climate change, the sustainability of the food production system, and the welfare of animals.
Therefore, a regular consumption of adequate B12 is important to avoid a sub-clinical deficiency that can go undetected for years. An elevated serum methylmalonic acid (MMA) level is a reliable indicator of B12 deficiency [216], while the serum B12 level is an insensitive indicator of B12 status. While serum B12 levels between 148 and 221 pmol/L (200–300 pg/mL) are considered borderline B12 deficiency [296], some individuals with B12 values in this range manifest neuropsychiatric problems and memory loss [297]. As a good preventative measure, all vegans should annually check their B12 status.

The intervention emphasized the value of a whole-food plant-based diet and minimized processed foods, saturated fats and added sugars. This was also represented in the provided meals at a local restaurant offering whole foods plant-based (vegan) options. While the intervention was presumably vegan, the authors did not clarify whether animal foods were “only” minimized or fully excluded.
