Blood clots and Erythritol
Recent research has raised concerns about potential cardiovascular risks associated with certain sugar substitutes, particularly erythritol. Here are the key points:
Erythritol and Blood Clotting Risk
A study led by researchers at the Cleveland Clinic found that erythritol, a popular artificial sweetener, may increase the risk of blood clots. The key findings include:
Participants who consumed erythritol-sweetened drinks showed signs of increased platelet activation, which is associated with blood clot formation.
Blood erythritol levels increased by more than 1,000 times after consumption and remained elevated for several days.
No similar effect was observed in participants who consumed glucose-sweetened drinks.
Mechanism and Implications
The researchers suggest that erythritol may enhance platelet reactivity, potentially leading to:
Increased risk of blood clot formation
Higher likelihood of cardiovascular events like heart attacks and strokes
This is particularly concerning for individuals already at risk for cardiovascular issues, such as those with diabetes or obesity.
Other Sugar Substitutes
While the focus has been on erythritol, another study raised similar concerns about xylitol:
Higher blood levels of xylitol were associated with increased risk of cardiovascular events.
Xylitol also enhanced blood clotting in laboratory and animal studies.
Recommendations and Caution
Health experts and researchers advise:
Moderation in consuming artificially sweetened products.
Considering natural sweeteners in small amounts (e.g., honey, maple syrup) as alternatives.
Consulting with healthcare providers, especially for those with existing cardiovascular risk factors
Food Processing
Chemical knowledge is applied to enhance food processing techniques, including:

Other Considerations
Use the outer leaves of vegetables when possible.
Save nutrient-rich cooking water for soups and stocks.
Choose processed foods with more nutrients to encourage and fewer constituents to limit.
Be mindful of added sugar, salt and saturated fats when processing foods at home
Processed sugar
Refined sugar, commonly found in many processed foods, is derived from natural sources such as sugar cane, sugar beets, and corn. The extraction process involves cleaning and cooking these plants to extract sugary juices, which are then processed to create sugar crystals. This refined sugar, primarily in the form of sucrose, is prevalent in various products, including soft drinks, baked goods, and sauces, contributing to a significant portion of the American diet, where average consumption can reach up to 34 teaspoons per day.
Health Implications
The consumption of refined sugars is linked to several health issues, including obesity, type 2 diabetes, cardiovascular disease, and potentially even some cancers. These sugars provide “empty calories,” meaning they offer little to no nutritional value, lacking essential vitamins, minerals, and fiber that are typically found in whole foods containing natural sugars, such as fruits and vegetables.
Refined sugars can cause rapid spikes in blood glucose levels, leading to increased hunger and cravings shortly after consumption. This contrasts with natural sugars, which are digested more slowly due to their presence in whole foods, providing a more sustained energy release and greater satiety.
Types of Refined Sugars
Common forms of refined sugars include:
Table Sugar (Sucrose): Extracted from sugar cane or beets.
High-Fructose Corn Syrup (HFCS): A sweetener made from corn that is widely used in processed foods.
Brown Sugar: A type of sugar that contains molasses, giving it a distinct flavor and color.
Other Sweeteners: Includes agave nectar and various syrups, which, despite being marketed as healthier alternatives, are still processed and can have similar health effects as traditional refined sugars
Fermented foods and the intestines
Fermented foods can have several beneficial effects on intestinal health:
Increased microbiome diversity: Consuming fermented foods enhances the diversity of gut microbes, which is associated with better digestive function and overall health.
Reduced inflammation: Fermented foods can decrease molecular signs of inflammation in the body. A study found that a diet rich in fermented foods led to decreased levels of 19 inflammatory proteins, including interleukin 6.
Improved gut barrier function: Fermented foods may help strengthen the walls of the intestines, reducing “leaky gut syndrome” and preventing harmful substances from entering the bloodstream.
Enhanced digestion: The probiotics in fermented foods can aid in the breakdown of nutrients, particularly lactose in dairy products, making them more digestible.
Support for the immune system: About 70% of the immune system resides in the gut. Probiotics from fermented foods can modulate immune responses and support defenses against pathogens.
Potential benefits for gastrointestinal disorders: Some fermented foods like kefir have shown promise in managing conditions like lactose malabsorption and H. pylori infections.
Production of beneficial compounds: The fermentation process can produce bioactive peptides, biogenic amines, and convert phenolic compounds into biologically active substances that may benefit health
Carbohydrates
Carbohydrates are an essential macronutrient that provide energy for the body. Here are some key points about carbohydrate-rich foods and their importance:
Carbohydrate-Rich Foods
Healthy sources of carbohydrates include:
Whole grains (brown rice, oatmeal, quinoa, whole wheat bread/pasta)

Chloride
Chloride is an important electrolyte that is found in many foods, often alongside sodium.
Chloride and nerve health
A lack of chloride-rich foods in the diet can potentially impact nerve health, as chloride plays an important role in nerve function. Here are some key points about the relationship between chloride intake and nerve health:
-
- Chloride is essential for proper nerve function. It helps regulate the transmission of electrical signals along nerve cells.
-
- Adequate chloride levels are necessary for maintaining the proper balance of fluids inside and outside of nerve cells, which is crucial for nerve signaling.
-
- Chloride deficiency, though rare, can potentially lead to nerve-related symptoms like muscle weakness, fatigue, and difficulty breathing.
-
- Severe chloride deficiency (hypochloremia) may cause more serious neurological issues like confusion or seizures in extreme cases.
-
- While outright chloride deficiency is uncommon in healthy individuals with varied diets, certain conditions or medications can lead to low chloride levels that may impact nerve function.
-
- Foods rich in chloride include table salt, seaweed, tomatoes, lettuce, celery, and olives. Ensuring adequate intake of these foods can help maintain proper chloride levels for nerve health.
-
- Chloride often works in conjunction with other electrolytes like sodium and potassium to support proper nerve and muscle function.
-

Incorporating a variety of these foods into your diet can help you meet the recommended daily intake of potassium, which is about 4,700 mg for adults.
For people with chronic kidney disease (CKD), the recommended potassium intake is typically lower than for those with healthy kidneys. Here are the key points about potassium limits for people with kidney issues:
Recommended Potassium Intake for CKD patients:
For people with mild to moderate CKD (stages 3-4), the general recommendation is to limit potassium intake to 2-4 grams (2000-4000 mg) per day.
For those with advanced CKD or on dialysis, a stricter limit of less than 3 grams (3000 mg) per day is often recommended.
Some guidelines suggest an even lower limit of 2-2.5 grams (2000-2500 mg) per day for those prone to hyperkalemia.
Factors Affecting Recommendations
The exact limit depends on the individual’s kidney function, medications, and other health factors.
Potassium restrictions often become more stringent as kidney function declines.
Patients should work with their nephrologist and renal dietitian to determine their personalized potassium limit.
Monitoring and Management
Regular blood tests are needed to check potassium levels.
The safe range for blood potassium is typically 3.5-5.0 mEq/L.
Dietary changes, medications, and other interventions may be used to manage potassium levels.
Rice
Rice is primarily composed of carbohydrates, mainly in the form of starches such as amylose and amylopectin. These carbohydrates are critical in determining the texture and cooking properties of rice. Amylose is a straight-chain molecule, while amylopectin is highly branched, affecting rice’s stickiness and firmness when cooked. Rice also contains about 7% protein, with a high digestibility rate, and provides essential nutrients like B vitamins, vitamin C, iron, magnesium, and zinc. The grain consists of three main parts: the bran, endosperm, and germ, each contributing to its nutritional profile.
Rice and Corn
The combination of rice and corn in various applications shows interesting chemical interactions. Substituting rice for corn in animal feed does not negatively affect rumen fermentation, suggesting rice as a viable alternative energy source. Nutritionally, colored rice and corn varieties contain richer essential nutrients and amino acids compared to their white counterparts. Rice and corn can also be combined in food products like vermicelli, where a mixture of 75% rice flour and 25% corn flour with carrageenan produces a favorable texture and taste. Additionally, rice and corn are used in fermented foods like ‘calugi,’ highlighting their versatility in different culinary traditions.
Refrigerating Rice and potatoes
Refrigerating cooked potatoes and rice affects their starch chemistry by increasing resistant starch content. When these foods are cooled after cooking, some of the gelatinized starch retrogrades, forming resistant starch (RS3), which resists digestion in the small intestine and is fermented in the colon. This process can reduce the glycemic response, making these foods potentially healthier. For example, cooling rice increases its resistant starch content, lowering its glycemic impact when reheated. However, reheating boiled potatoes can reduce resistant starch content back to levels similar to freshly cooked potatoes
Cassava
Cassava, also known as manioc or tapioca, is a starchy root crop rich in carbohydrates, primarily starch, with low protein and fat content. It contains cyanogenic glycosides, which can release cyanide if consumed raw, making proper preparation essential. Cassava leaves, in contrast, are high in protein, vitamins, and minerals. The root is a significant energy source, providing high caloric yield per hectare. Cassava is versatile, used in various food products like tapioca and garri, and is a staple in many tropical regions
Sweet potatoes
Sweet potatoes are rich in various bioactive compounds and nutrients, contributing to their health benefits. They contain macronutrients like starch, dietary fiber, and protein, along with micronutrients such as vitamins B, C, E, provitamin A (carotenoids), anthocyanins, flavonoids, and minerals like potassium, magnesium, and iron. Different parts of the plant, including tubers and leaves, offer diverse nutrients and bioactive compounds like phenolic acids and anthocyanins, which have antioxidative and anti-inflammatory properties. Cooking methods can affect the phenolic content, with some methods like steaming increasing it.
Lentils
Lentils (Lens culinaris) are nutritionally rich legumes, containing approximately 25% protein and 60% carbohydrates, along with essential amino acids like lysine and arginine. They are also a source of polyphenols, such as phenolic acids, flavan-3-ol, flavonols, and anthocyanins, which have antioxidant properties. Lentils contain significant minerals, including iron, zinc, magnesium, and phosphorus, which are crucial for various biological functions. Additionally, they have low fat content, with a composition of saturated, monounsaturated, and polyunsaturated fatty acids. Lentils are valued for their health benefits, including cardiovascular and metabolic improvements.
Basil
Basil, particularly Ocimum basilicum, is rich in essential oils and secondary compounds that contribute to its distinctive aroma and potential health benefits. Key chemical constituents include methyl cinnamate, linalool, estragole (methyl chavicol), and eugenol, which vary among different basil cultivars and growing conditions. These compounds are responsible for basil’s aromatic properties and have been studied for their antimicrobial, antifungal, and potential anticancer activities. Basil is also used in traditional medicine for various ailments and as a flavoring in culinary applications
Fish
The chemistry of fish encompasses various aspects, including their composition and the environmental factors affecting them. Fish contain amino acids like glycine and glutamate, which contribute to their flavors. Ocean fish accumulate bromophenols from algae, giving them a characteristic “seacoast smell.” The compound trimethylamine (TMA) is responsible for the “fishy” odor, formed from trimethylamine oxide (TMAO) after fish die. Additionally, fish are often subject to chemical contamination, with mercury and polychlorinated biphenyls (PCBs) being common concerns in fish consumption advisories
Ginger
Ginger, scientifically known as Zingiber officinale, contains a variety of chemical compounds, including phenolic compounds like gingerols and shogaols, and terpenes such as zingiberene. Gingerols, the primary pungent compounds, can transform into shogaols when ginger is dried or heated, increasing its pungency. These compounds contribute to ginger’s characteristic flavor and aroma, and they have been studied for their antioxidant, anti-inflammatory, and potential anticancer properties. Ginger also contains zingerone, which is less pungent and forms during cooking.
Ginger has shown potential in alleviating neuropathic pain through its anti-inflammatory properties. Gingerol-enriched ginger supplementation can reduce pain sensitivity and neuroinflammation by modulating the gut-brain axis. Studies in animal models have demonstrated that ginger can decrease hypersensitivity and emotional responses associated with neuropathic pain, potentially by improving intestinal permeability and reducing neuroinflammation markers in the brain and gut. Additionally, hot ginger soaks have been suggested as a home remedy for painful neuropathy. However, more research is needed to confirm these effects in humans.
Ginger has several benefits for gastrointestinal (GI) tract health. It is known for its ability to relieve nausea and improve digestion by accelerating gastric emptying, which can help alleviate symptoms of indigestion and constipation. Ginger’s anti-inflammatory and antioxidant properties also contribute to its gastroprotective effects, potentially soothing the gut lining and reducing inflammation. Additionally, ginger can modulate gut microbiota composition, which may further support digestive health. Despite these benefits, more extensive studies are needed to fully understand the optimal dosages and mechanisms of ginger’s effects on the GI tract.
Drinking hot water with boiled ginger and honey may have several effects on metabolism. Ginger is known to increase thermogenesis, which enhances calorie burning and boosts metabolism. It can also improve digestion by increasing enzyme production, thereby aiding nutrient absorption and reducing bloating. Ginger’s appetite-suppressing properties may help control hunger and reduce calorie intake.
Stories of my grandma using ginger internally and externally
My grandma died at 94 yrs of age due to poor nutrition and raising a big family. During her lifetime, she had used ginger internally and added in her massage oil. She has no medications, using only ginger and garlic for everyday use internally and externally. She would boil ginger and garlic for her drink and add ginger and garlic in her massage oil of coconut oil base.
Additionally, ginger has anti-inflammatory and antioxidant properties, which can support overall metabolic health. However, while ginger shows promise in weight management, more research is needed to confirm its efficacy.
Ginger boosts thermogenesis in the body by activating transient receptor potential vanilloid 1 (TRPV1) channels, which are involved in the body’s heat production process. This activation leads to increased energy expenditure and calorie burning, contributing to a higher basal metabolic rate. Ginger’s thermogenic effect is also linked to enhanced satiety and reduced hunger, which can help in weight management. Additionally, gingerols and shogaols, compounds found in ginger, play a role in stimulating these thermogenic pathways.
Ginger may support nerve health through several mechanisms. It contains choline, which is crucial for the production of neurotransmitters that facilitate nerve signaling. Additionally, ginger’s anti-inflammatory properties can help reduce neuroinflammation, which is beneficial for nerve function. Gingerol, a key compound in ginger, has been shown to penetrate the blood-brain barrier, potentially aiding in protecting nerve cells and improving brain health. These properties suggest that ginger could play a role in maintaining and enhancing nerve health.

Exposure and Risk
Levels of 4-MEI in foods and beverages vary widely depending on the manufacturing process.
Some studies have estimated cancer risks from 4-MEI exposure through soda consumption, but the actual risk remains uncertain.
The overall cancer risk from 4-MEI in caramel coloring is likely low for most people, especially compared to other dietary factors.
Recommendations
While the evidence for carcinogenicity in humans is limited, some experts and organizations recommend:
Reducing consumption of foods and beverages containing caramel coloring, especially those with higher levels of 4-MEI.
Manufacturers should work to minimize 4-MEI formation in caramel coloring production.
Further research to better understand the long-term health effects of 4-MEI exposure in humans
