'Kosher Gelatin Marshmallows: Glatt Kosher and "OU-Pareve",' an article that appeared in Kashrus Magazine, explains the distinctions. A quote from the article is as follows: '...since the gelatin product is from hides or bones—not real flesh—and has undergone such significant changes, it is no longer considered 'fleishig' (meat) but 'pareve', and can be eaten with dairy products.' [...] Rennet is like gelatin in the sense that it's a common food additive but the foods containing it are often considered vegetarian.
The first discovered written use of the term "vegetarian" originated in 1839 and refers to what was previously described as a vegetable regimen or diet, for example in print in 1811.[12] Modern dictionaries based on scientific linguistic principles have always explained its origin as an irregular compound of vegetable (in the adjectival sense of any plant still common today)[13] and the suffix -arian (in the sense of "supporter, believer" as in humanitarian), but there were amateur attempts, even by a Latin scholar not trained in linguistics, to find other origins of the word.[14] The term was popularized with the foundation of the Vegetarian Society in Manchester in 1847,[15] although it may have appeared in print before 1847.[15][16][17] The earliest occurrences of the term seem to be related to Alcott House—a school on the north side of Ham Common, London—which was opened in July 1838 by James Pierrepont Greaves.[16][17][18] From 1841, it was known as A Concordium, or Industry Harmony College, from which time the institution began to publish its own pamphlet entitled The Healthian, which provides some of the earliest appearances of the term "vegetarian".[16]
A number of medieval rabbis (e.g., Joseph Albo and Isaac Arama) regard vegetarianism as a moral ideal because the slaughter of animals might cause the individual who performs such acts to develop negative character traits. Many modern rabbis, by contrast, advocate vegetarianism or veganism primarily because of concerns about animal welfare, especially in light of the traditional prohibition on causing unnecessary "pain to living creatures" (tza'ar ba'alei hayyim).[187]
My diet is personally about 70 percent plants and 30 percent animal-derived foods. I usually consume about 70 percent raw plant-based foods, and 30 percent of my diet is organic grass-fed beef, organic pastured dairy, wild-caught fish (wild-caught salmon is my favorite), and free-range organic poultry and eggs. I’ve tried a number of diets, including vegetarian, vegan and pescatarian, and have found I really feel the best following this ratio. I call this ratio the healing foods diet and have also found this to have the best results with my patients, as well. Here’s the new, updated healing foods shopping list so you can have an extensive food guide to follow. If it’s on the list, it’s good to go. 

Calcium helps build and maintain strong teeth and bones. Milk and dairy foods are highest in calcium. However, dark green vegetables, such as turnip and collard greens, kale, and broccoli, are good plant sources when eaten in sufficient quantities. Calcium-enriched and fortified products, including juices, cereals, soy milk, soy yogurt and tofu, are other options.
Basically, the effect of exercise on our weight is vastly overrated. That’s why it’s only number 15 on this list. There are other things you need to take care of first. It’s not a good idea to eat bad food, drink sugar water (so-called “sports drinks”) or be on medications which force you to exercise for hours daily just to compensate. Metaphorically that’s like digging a hole, into which you put your ladder, on which you stand and paint the basement-level windows of your house.

Omega-3 fatty acids are good fats that may help lower blood pressure, improve heart health, and stave off age-related dementia. There are two kinds. Most of the health benefits are linked to docosahexaenioc acid (DHA), found mainly in fatty fish, as well as fortified foods like eggs. If you don't eat either of these foods, you might want to consider a supplement. Pumpkin seeds, flaxseeds, walnuts, and canola oil are all good sources of alpha-linolenic acid (ALA), an omega-3 fatty acid beneficial for heart health.

Being in optimal ketosis for a prolonged period of time (say, a month) will ensure that you experience the maximal hormonal effect from eating a low-carb diet. If this doesn’t result in noticeable weight loss, you can be certain that too many carbs are NOT part of your weight issue and not the obstacle to your weight loss. There are, in fact, other causes of obesity and being overweight. The next three tips in this series might help you.
Some people feel better supplementing the already active T3 (sometimes prepared from pig thyroid glands), as it can give a stronger effect than the T4 hormone, but its effect is often harder to control. Swedish healthcare rarely prescribes or offers such T3 treatment, as it often lacks advantages and may pose a risk when doses are high for an extended period of time.
You’re more likely to eat more—and eat more high-fat, high-calorie foods—when you eat out than when you eat at home. Restaurants today serve such large portions that many have switched to larger plates and tables to accommodate them. You’ll gasp when you see just how bad the unhealthiest restaurant meals in America are. Don’t miss these 9 ways your kitchen setup can help you lose weight.

In addition, animal agriculture is a large source of greenhouse gases. According to a 2006 report it is responsible for 18% of the world's greenhouse gas emissions as estimated in 100-year CO2 equivalents. Livestock sources (including enteric fermentation and manure) account for about 3.1 percent of US anthropogenic GHG emissions expressed as carbon dioxide equivalents.[208] This EPA estimate is based on methodologies agreed to by the Conference of Parties of the UNFCCC, with 100-year global warming potentials from the IPCC Second Assessment Report used in estimating GHG emissions as carbon dioxide equivalents.

Vegetarian diets typically contain similar levels of iron to non-vegetarian diets, but this has lower bioavailability than iron from meat sources, and its absorption can sometimes be inhibited by other dietary constituents.[81] According to the Vegetarian Resource Group, consuming food that contains vitamin C, such as citrus fruit or juices, tomatoes, or broccoli, is a good way to increase the amount of iron absorbed at a meal.[82] Vegetarian foods rich in iron include black beans, cashews, hempseed, kidney beans, broccoli, lentils, oatmeal, raisins, spinach, cabbage, lettuce, black-eyed peas, soybeans, many breakfast cereals, sunflower seeds, chickpeas, tomato juice, tempeh, molasses, thyme, and whole-wheat bread.[83] The related vegan diets can often be higher in iron than vegetarian diets, because dairy products are low in iron.[68] Iron stores often tend to be lower in vegetarians than non-vegetarians, and a few small studies report very high rates of iron deficiency (up to 40%,[84] and 58%[85] of the respective vegetarian or vegan groups). However, the American Dietetic Association states that iron deficiency is no more common in vegetarians than non-vegetarians (adult males are rarely iron deficient); iron deficiency anaemia is rare no matter the diet.[86]
People who eat a high amount of vegetables and fruit daily tend to have the best protection against weight gain as they age. Because plant-based foods like fresh veggies and fruit are very low in calories yet are high in terms of volume and therefore take up lots of room in your stomach, they are filling and keep you from over-eating. Plant-based (or “mostly plant-based”) diets are tied to a lowered risk for obesity, lower BMI status and reduced complications related to obesity, such as heart problems or metabolic syndrome.
