TL;DR - Organic foods don't seem to have a significant difference as of what studies can prove, which is why conventional or organic, people should make sure they're getting the proper nutrients that their bodies need. Brief History of Pesticide Usage The first recorded use of insecticides is about 4500 years ago by Sumerians who used sulphur compounds to ...

The quoted "1-2" pounds per week (or approximately 0.5 - 1 kilo) is based on the traditional 3500 calories burned = 1 pound of fat. Now, while the exact figure of 3500 calories is somewhat open to debate, that is the rationale. 500 calories a day = 1 pound of loss per week. The problem with crash dieting is twofold. One, the majority of the weight lost is ...

There are a few considerations when looking at a healthy lacto-ovo vegetarian diet. Complete Proteins This is fairly easy in this type of diet, as eggs contain complete proteins. There are also a few plant sources (such as quinoa, buckwheat and hempseed) that contain either a complete protein profile or the 9 essential amino acids in good amounts. Hempseed ...

These are some reasons: Free sugars contribute to the overall energy density of diets. [1] Free sugars promote a positive energy balance. (= excess of energy intake) [1] Drinks that are rich in free sugars increase overall energy intake by reducing appetite control. [1] Fruit sugar is less cariogenic than refined sugar [1] Some sources talk about the ...

In general, no. A ketogenic diet is one where carbohydrates are eliminated and protein is restricted, to force the body to obtain its energy from the metabolism of fatty acids and ketone bodies, rather than the normal method of glucose metabolism. It is used primarily to treat otherwise-intractible epilepsy, and to a lesser extent, to deal with certain ...

Long answer There are proteins in many vegetable foods, the difference with meat is the percentage of protein. Here you have a table of protein content of most protein-rich plant foods, plus beef meat for comparison (values are g of protein ...

Summary The primary risk of excessive water intake is hyponatremia (low sodium level in the blood). While a healthy person who drinks 6-8 liters of water daily is unlikely to suffer significant hyponatremia, people who drink this much often have psychiatric illness that is accompanied by poorly understood hormonal changes that may indeed cause ...

The original 3500 calorie theory comes from a correspondence published in 1959, by a Dr. Max Wishnofsky, where he equates it to pounds lost in observed obese patients. It's further perpetuated by badly applied mathematics. White adipose tissue has the responsibility for energy storage in the body. This tissue is composed of anywhere from 60% to 85% lipid (...

I have eaten McDonalds for lunch every (week) day for the past 2+ years, I can tell you it has nothing to do with weight gain or loss. For the vast majority of people, losing and gaining weight is all about calories; nothing else. Genetics plays a role, but it is insignificant in the grand scheme of things. There are many problems with the quality of food ...

This is a diet produced by a group of researchers at USC led by a Dr. Longo that was used to try to avoid the effects of prolonged fasting (PF), by instead using a 5 day period once a month where nutrient intake was slashed by 34-54%. Here is the summary from the publication in this June's "Cell Metabolism", that outlines the effects and benefits. It grew ...

The American Heart Association no longer condemns eggs in its guidelines. But it does recommend that people limit themselves to 300 milligrams of cholesterol daily (a single egg has about 200 milligrams of cholesterol, as well as a mix of saturated and unsaturated fats, including the monounsaturated kind found in olive oil). The federal government, in its ...

In general, it is the basal metabolic rate (BMR) of the organism which in a person who doesn't exercise more than average, consumes most of the calories of the daily intake. It is dependent of age, sex, population and fat-free mass, i.e. the mass of muscles in your body, which consume a lot of energy just for maintenance. Studies show that it can vary ...

The German Federal Institute for Risk Assessment has established a tolerable daily intake (TDI) of 0.1 mg coumarin per kg body weight, but also advises that higher intake for a short time is not dangerous. {1} Meanwhile, the Occupational Safety and Health Administration (OSHA) of the United States does not classify coumarin as a carcinogen for humans. {2} ...

Your have three questions in one now: Is a ketogenic diet appropriate for a one year old? Is a carbohydrate reduced diet appropriate for a one year old? Is milk really necessary for a one year old, or can I replace it with something else? Milk Milk is a very obvious nutritional choice for a small child. You mention that your child has been drinking ...

As already pointed out, nuts and legumes make very good snacks. My only caution with the nuts is that they are also very calorie dense, so to have a filling snack you may add more calories than you would want. You can combine them with fruit, yogurt or other similar foods to make a healthy snack that isn't as high in calories per serving. If you want to ...

To directly answer your question: it is not. "Natural" sugar is no healthier than "refined" sugar, and sugar in fruits is no healthier than sugar in juice. Sugar molecules are sugar molecules, regardless of whether they are "natural" or "refined." There is no difference. However, I believe the real question here is why the WHO is recommending one type ...

There is some evidence that sugar does suppress the immune system. The study that everyone seems to point to was conducted in 1973, where they fed sugar in 100g doses to people and measured the effect on phagocytosis (where immune cells engulf invader bacteria to destroy it). The end result was that sugar intake did appear to suppress the ability of the ...

First of all, the 1000-2500 calorie statement from the answer to this question is not due to formula inaccuracies (only 0.5% of the variation were attributed to that), but is the actual measured BMR in a study within Scottish population. Second, we know from the above mentioned question in SE that the BMR is dependent, amongst others, of fat-free body mass (...

No individual food is "not healthy" it is your diet that overall is healthy or not. Using white flour instead of whole flour gives away a chance to eat some fibre. A page from the UK's NHS explains how much fibre you need and the role it plays in health. In addition, your friends may object to wheat or flour (even whole wheat) because it is a carbohydrate. ...

There is one systematic review on this topic. This study was published in the American Journal of Clinical Nutrition, which is the most respected journal in their discipline. As so, I consider this study perhaps the most important publication on this topic. Main conclusion was that the literature is scarce with regard to intermittent fasting. Small studies ...

I seem to perceive some confusion in your question, and I'll try to clarify all doubts as much as I can. Olive oil is one of the best oils you can use to cook. It is mainly composed by monounsaturated fatty acids (1), that are neutral to cardiovascular risk and blood cholesterol. There are some oils that are better, by this point of view, like canola oil, ...

Judging from your description, you're most probably doing everything correctly. But ok, if you wanted to be absolutely sure, you really would have to precisely measure your calorie intake vs calorie expenditure (with a tool like cronometer or sth). And as far as gaining 100 grams in 2 days goes, that's just jumping to conclusions and easily falls within ...

Provided that you are healthy, not suffering from a cold, disease state or other suppression of the immune system, moderate exercise during fasting periods should not impact your health. For submaximal efforts, you may notice earlier fatigue, and there will be definite performance impacts the closer you get to maximal efforts. Caveat: You are still ...

The problem with these diets is not only do they not treat the cancer, but the false hope they offer prevents people (in this case, a woman with breast cancer) from receiving treatment that does reduce or potentially even eliminate the cancer. Breast cancer is a common cancer in women, and it was politicized a couple of decades ago, meaning the ...

The study you link explains that the problem with grapefruit juice is its tendency to cause inhibition of the CYP3A4 liver enzyme, which is needed for the metabolism of many medications - including some statins prescribed to lower cholesterol. The wikipedia article on grapefruit explains this further, in particular: Mechanism of grapefruit–drug ...
