Oct 23, 2013 · In the human body, linamarin can come in one end and go out the other intact, but if it gets broken down during digestion and runs into the enzyme linamarase, it will produce cyanide in the gut.

Among the plant metabolites, inherent plant toxicants are believed to play an ecological role in plant physiology, proliferation, or defense. Also, some of the secondary metabolites repel predators and are thus toxic or unpleasant to humans [ 5 , 6 ], while others have different purposes, including plant physiological defense against insects, bacteria, fungi, and viruses [ 4 , 5 , 7 , 8 ].
Apr 29, 2023 · Plant chemistry and toxicology are complex with a rich history. Much about plant chemistry remains unknown, and our understanding relies on animal research combined with documented human experiences. The dynamic science of pharmacognosy, which highlights the therapeutic value of plants, has elucidated several major classes of organic molecules found in plants, of which alkaloids represent one ...

Like humans, plants are evolved to survive and reproduce. In order to protect and perpetuate themselves, plants are armed with an arsenal of plant toxins and antinutrients. Since most of our leafy friends lack fangs and claws, and they don’t have legs to flee on, they evolved protective plant toxins and antinutrients, including naturally-occurring ...
Plant toxins and antinutrients are the chemicals plants use to defend themselves from fungi, insects, and animal predators. Humans are predators, and many of the chemicals plants produce are harmful to us. Though plant toxins and antinutrients are often used interchangeably, plant toxins exhibit their negative effects through purely toxic means. Wh...
Different parts of plants can produce numerous toxins at various levels of intensity. Yet we eat just about every part of plants. Carrots and turnips are the roots; spinach and kale are the leaves; celery and asparagus are the stems; broccoli and cauliflower are the flowers; oranges, apples, and grapes are the fruit; lima beans, coffee beans, and c...
Phytic acid is a natural, protective substance found in many plants, usually in the seeds (nuts, grains, and legumes). Its main job is to hold on to the essential minerals that the baby plant needs to grow. Found in abundance in whole grains, legumes and nuts, phytates are used by plants to store phosphorous. Yet they don’t make it available to our...
Lectins are a group of proteins found in most plant foods. As part of the plant’s immune system they protect against an array of predators and microbes (bacteria, viruses, fungi, and parasites). When stressed, damaged, or under attack, for example by an insect munching on its leaves, plant lectins can be toxic and act as a deterrent. Scientists hav...
Saponins are found primarily in legumes and grains. They’re the chemicals that create the foamy substance on the surface of water when you soak beans. Saponins can cause harm by binding to various nutrients, inhibiting our ability to use them. They also inhibit digestive enzymes causing a decrease in protein digestibility and absorption. Some sapon...
Most people have heard of tannins as they relate to red wine and tea, but they’re also found in coffee and chocolate. Tannins are what give these foods their bitter, dry taste. Tannins are naturally-occurring polyphenols that easily bind with other compounds like proteins and minerals. You can find them in various plants, seeds, bark, wood, leaves,...
Glucosinolates are chemicals found in cruciferous vegetables like Brussels sprouts, broccoli, cabbage, cauliflower, kale, and many more. They tend to produce a telltale sulfur-like smell as part of their defense system. Glucosinolates prevent the body from absorbing iodine, flavonoids, and minerals such as iron and zinc. Studies show that a higher ...
Cruciferous vegetables also contain the chemical sulforaphane. Most of the sulforaphane you eat gets absorbed into your bloodstream, where it can damage intracellular structures like mitochondria and enzymes. Our bodies respond with powerful antioxidants to minimize the damage. But this response depletes our antioxidants leaving other cells vulnera...
The leaves of plants are some of the most highly touted “superfoods.” Thanks to Popeye, spinach usually tops the list of “healthy greens.” But spinach contains high levels of oxalates. Oxalatesare antinutrients that deplete calcium and iron, stealing essential vitamins and minerals from our bodies. The presence of oxalic acid in cooked spinach is r...
Jul 6, 2018 · Abstract. Alkaloids are plant secondary metabolite. They are well known nitrogen-containing natural bioactive compounds. Cutting edge research is going on alkaloids to unravel novel therapeutic approaches. Literature reveals that alkaloids contribute multiple biological activities and some alkaloids transform into active metabolites too.
