Can incorporating nopal or prickly pear cactus into one’s diet help individuals trying to lower blood glucose, inflammation, and risk factors associated with heart and metabolic diseases?
Nopal
Nopal, also known as prickly pear cactus, is a versatile vegetable that can be added to nutrition plans to increase fiber intake, vitamins, minerals, and plant-based compounds. It grows in the U.S. Southwest, Latin America, and the Mediterranean. The pads, or the nopales or cactus paddles, have a texture like okra and slight tartness. The prickly pear cactus fruit, referred to as tuna in Spanish, is also consumed. (University of Arizona Cooperative Extension, 2019) It is often used in fruit salsas, salads, and desserts and is available as a supplement in tablet and powder form.
Nopal is highly nutritious, low in calories, free of fat, sodium, or cholesterol, and full of fiber, vitamins, minerals, and betalains. (Parisa Rahimi et al., 2019) Betalains are pigments with anti-inflammatory properties. The variety of fibers creates a low glycemic index (measures how much a specific food raises blood sugar levels after consumption) of about 32, a recommended addition to a diabetes-friendly diet. (Patricia López-Romero et al., 2014)
Compounds
Nopal contains a variety of beneficial carbohydrates, vitamins, and minerals.
Nopal has soluble and insoluble fiber, which benefits blood sugar.
It also contains vitamin A, carotenoids, vitamin C, calcium, and plant-based compounds like phenols and betalains. (Karina Corona-Cervantes et al., 2022)
Blood Sugar Regulation
Research has evaluated regular nopal consumption and supplementation for blood sugar control. A study on blood sugar evaluated adding nopal to a high-carbohydrate breakfast or a breakfast high in soy protein in Mexican individuals with type 2 diabetes. The study found that consuming nopales, about 300 grams or 1.75 to 2 cups before a meal, could reduce after-meal/postprandial blood sugars. (Patricia López-Romero et al., 2014) An older study had similar results. (Montserrat Bacardi-Gascon et al., 2007) Individuals were randomly assigned to consume 85 grams of nopal with three different breakfast options:
Chilaquiles – a casserole made with corn tortilla, vegetable oil, and pinto beans.
Burritos – made with eggs, vegetable oil, and pinto beans.
Quesadillas – made with flour tortillas, low-fat cheese, avocado, and pinto beans.
The groups assigned to eat nopales had reductions in blood sugar. There was a:
30% reduction in the chilaquiles group.
20% decrease in the burrito group.
48% reduction in the quesadilla group.
However, the studies were small, and the population was not diverse. so further research is needed.
Increased Fiber
The combination of soluble and insoluble fiber benefits the gut in various ways. Soluble fiber can act as a prebiotic, feeding beneficial bacteria in the gut and assisting in removing low-density lipoprotein (LDL) cholesterol from the body. Insoluble fiber increases transit time, or how quickly food moves through the digestive system and promotes bowel regularity. (Centers for Disease Control and Prevention, 2022) In a short-term randomized clinical control trial, researchers found an improvement in irritable bowel syndrome symptoms in individuals supplemented with 20 and 30 grams of nopal fiber. (Jose M Remes-Troche et al., 2021) For individuals not used to consuming fibrous foods, it may cause mild diarrhea, so it is recommended to increase intake slowly and with adequate water to prevent gas and bloating.
Plant Based Calcium
One cup of nopal provides 244 milligrams or 24% of daily calcium needs. Calcium is a mineral that optimizes bone and teeth health. It also assists in blood vessel contraction and dilation, muscle function, blood clotting, nerve transmission, and hormonal secretion. (National Institutes of Health. Office of Dietary Supplements 2024) Individuals who follow diets that exclude dairy products can benefit from plant-based calcium sources. This includes cruciferous vegetables like kale, collards, and arugula.
Other Benefits
Studies done in animals and test tubes suggest that fresh nopal and extracts may assist in reducing triglycerides and cholesterol in metabolic dysfunction-associated steatotic liver disease or when unhealthy amounts of fat accumulate in the liver. (Karym El-Mostafa et al., 2014) Other potential benefits with limited evidence include:
Unless individuals are allergic to it, most can eat whole nopal without a problem. However, supplementing is different because it provides a concentrated source. Individuals taking medication to manage diabetes and consuming nopal regularly may contribute to an increased risk of developing hypoglycemia or low blood sugar. Dermatitis has also been reported from contact with the cactus spines. (U.S. Department of Agriculture, FoodData Central, 2018) There have been rare reports of bowel obstruction in individuals who consume large amounts of the seeds found in the fruit. (Karym El-Mostafa et al., 2014) Ask a registered dietitian or primary healthcare provider if nopal can provide safe benefits.

For individuals looking to improve their diet, can knowing the different salt types help in food preparation and health?
Salt Types
Salt brings out the natural flavor of foods and can be used as a preservative. Salt types come in various colors and textures for cooking, flavor, and health. Some are considered healthier compared to regular table salt, like pink Himalayan salt and different sea salts. Some individuals prefer them because most go through less processing and can have more trace minerals like magnesium and potassium. However, all salts are healthy in moderation, as sodium is a necessary part of a balanced diet. Although essential for the body, sodium can be harmful when too much is consumed. A study examining consumer-grade pink Himalayan sea salts available in Australia determined that to receive the additional health benefits of the minerals from this type of salt, individuals must consume so much that it elevates the amount of sodium in the body to dangerous levels. (Flavia Fayet-Moore et al., 2020)
Salt
Salt is a mineral made from the combined elements:
Sodium – Na
Chlorine -Cl
Together, they form crystallized sodium chloride NaCl.
The majority of salt production comes from evaporated seawater and salt mines. Many salts used in food preparation are iodized. Iodine is added to various refined salt products to help meet nutritional requirements. Iodine intake levels that fall below the recommended values could result in a deficiency and develop goiter. Goiter is associated with hypothyroidism. (Angela M. Leung et al., 2021) Lack of iodine can also have adverse effects on growth and development. (National Institutes of Health Office of Dietary Supplements. 2023)
Essential for Health
Salt sustains life and optimal bodily function. Sodium and chlorine are important elements that maintain:
Cellular balance
Circulation
Blood sugar levels
Sodium is a mineral and an electrolyte. Common electrolytes include potassium, calcium, and bicarbonate. Without adequate sodium levels, the brain cannot send the necessary impulses to the rest of the body to function properly. However, consuming too much salt can cause health issues.
Higher salt intake in individuals who are sensitive to salt can increase blood pressure.
Doctors usually recommend that individuals with hypertension reduce sodium intake or follow a low-sodium diet.
Elevated sodium levels also cause water retention – considered a protective response as the body works to regulate serum sodium levels concentration in the blood to maintain balance.
If levels are too high, a condition known as hypernatremia can develop, which can cause:
Excessive thirst
Vomiting
Infrequent urination
Diarrhea
Sodium levels that are too low can lead to hyponatremia, which can cause:
Though there are different types of salt, they all contain roughly the same amount of sodium.
Types
The average sodium intake by adults is around 3,393mg per day, ranging between 2,000–5,000mg. Guidelines recommend a maximum intake of 2,300mg per day. (U.S. Department of Health and Human Services and U.S. Department of Agriculture. 2020) Whether from unhealthy dietary choices like processed foods or incorrect knowledge of sodium content when cooking, an American Heart Association survey showed that more than half of respondents inaccurately stated that sea salt had a lower sodium content than table salt. (American Heart Association. 2024)
Refined – Table Salt
Refined/iodized salt is finely granulated and commonly used in cooking. This type is highly refined to remove impurities and eliminate trace minerals often found in specialty salts. Because the salt is finely ground, anti-caking agents are added to ensure the salt doesn’t clump. Some table salts also have added sugar and other additives.
Refined table salt is about 97–99% sodium chloride (NaCl).
Iodine is added to prevent iodine deficiency.
Individuals trying to reduce sodium intake but meet iodine levels can do so with foods like eggs, dairy products, and fish.
Kosher
Kosher salt is coarse and flakey and can add a crunchy texture to dishes and drinks. Pure kosher salt does not contain additives like anti-caking agents and iodine. The size of the salt crystals is ideal for drawing out moisture.
Per teaspoon, kosher salt generally has less sodium than 1 teaspoon of table salt.
Because it has a coarser grain, less salt fits in the measuring spoon.
Sea Salt
Sea salt is produced from evaporated seawater and comes as fine grains or large crystals. Examples include:
Black Sea
Celtic
French – fleur de sel
Hawaiian sea salt
Sea salt can have trace amounts of minerals like iron, potassium, and zinc, which can produce different flavors in cooking but no additional health benefits with normal consumption. Some sea salts may also contain trace amounts of microplastics. However, research indicates these amounts are too low to warrant public health concerns. (Ali Karami et al., 2017)
Himalayan Pink Salt
Himalayan pink salt is mined in the red salt range in Pakistan, the second-largest salt mine in the world, and in the Andes mountains of Peru. Trace amounts of iron oxide make the salt pink. It is typically used at the end of cooking to add flavor and a crunch. Himalayan salt is popular for its health benefits and mineral properties. However, using Himalayan salt over other types has no known health advantages. Researchers concluded that the potential health benefits provided by the higher nutrient content would be counteracted by the large amount of sodium that would need to be consumed. (Flavia Fayet-Moore et al., 2020)
Substitutes
Salt substitutes contain some or all sodium and potassium, magnesium, or other minerals. Substitutes can be half sodium chloride and half potassium chloride. Monosodium glutamate/MSG can also be used as an alternative. A study found that substituting salt with MSG is safe and comparable to salt flavor. (Jeremia Halim et al., 2020) Individuals often use substitutes on a sodium-restricted diet but should check with their doctor before using these products, especially if they have kidney conditions.

For individuals looking to spice up their diet, can jalapeño peppers provide nutrition, and be a good source of vitamins?
Jalapeño Pepper Nutrition
Jalapeños are one of many types of chili peppers that are used to accent or garnish and add heat to a dish. This pepper variety is generally harvested and sold when it is a glossy dark green but turns red as it matures. The following nutrition information for one 14-gram jalapeño pepper. (FoodData Central. U.S. Department of Agriculture. 2018)
Jalapeño peppers contain very little carbohydrates and cannot be tested with the standard GI methodology. (Fiona S. Atkinson et al., 2008)
6 grams of carbohydrates in 1-cup serving has an extremely low glycemic load, meaning the peppers do not raise blood sugar levels rapidly or provoke an insulin response. (Mary-Jon Ludy et al., 2012)
Fat
Jalapeños have a trace amount of fat that is mostly unsaturated.
Protein
The peppers are not a recommended source of protein, as they contain less than a gram of protein in a full cup of sliced jalapeños.
Vitamins and Minerals
One pepper contains about 16 milligrams of vitamin C, about 18% of the recommended daily allowance/RDA.
Jalapeños are a good source of vitamin A, which supports skin and eye health.
In 1/4 cup sliced jalapeño peppers, individuals acquire around 8% of the recommended daily amount of vitamin A for men and 12% for women.
Jalapeños are also a source of vitamins B6, K, and E.
Health Benefits
Many health benefits have been attributed to capsaicin which is the substance that generates the heat in the peppers, including alleviating pain and itching by blocking a neuropeptide that transmits those signals to the brain. (Andrew Chang et al., 2023)
Pain Relief
Research shows capsaicin – supplements or topical ointments/creams – can relieve nerve and joint pain. (Andrew Chang et al., 2023)
Lower the Risk of Heart Disease
A study of individuals with low levels of healthy HDL cholesterol, who are at risk of coronary heart disease/CHD, showed that capsaicin supplements improved risk factors for CHD. (Yu Qin et al., 2017)
Reduce Inflammation
The vitamin C in the peppers acts as an antioxidant, which means it can repair cells damaged by oxidative stress and reduce inflammation.
They can be consumed raw, pickled, canned, or smoked/chipotle peppers and are hotter than fresh or canned because they are dried and treated.
Storage and Safety
Fresh jalapeños can be stored at room temperature for a few days or in the refrigerator for about a week.
Once a jar is opened, keep it in the refrigerator.
For an open can of peppers, transfer to a glass or plastic container for refrigerator storage.
Peppers can be frozen after preparing by cutting off the stems and scooping out the seeds.
Frozen jalapeños are best within 6 months for the best quality, but can be kept for much longer.
Preparation
Removing the seeds can help reduce the heat.
Jalapeños can be eaten whole or sliced and added to salads, marinades, salsa, or cheeses.
Some add jalapeños to smoothies for a spicy kick.
They can be used in various recipes for added heat and tanginess.

For individuals watching their food intake during the Thanksgiving holiday, can knowing the nutritional value of turkey help maintain diet health?
Nutrition and Benefits
Minimally processed turkey can be a beneficial source of protein, vitamins, and minerals. However, processed turkey can be high in sugar, unhealthy fats, and sodium.
Sarcopenia, or muscle wasting, commonly leads to frailty in elderly individuals.
Getting enough protein at every meal is essential for older adults to maintain muscle mass and physical mobility.
Turkey can help meet guidelines suggesting lean meat consumption 4-5 times a week to maintain muscle health with aging. (Anna Maria Martone, et al., 2017)
Reduces Diverticulitis Flare-Ups
Diverticulitis is inflammation of the colon. Dietary factors that influence the risk of diverticulitis include:
Fiber intake – lowers risk.
Processed red meat intake – raises risk.
Intake of red meat with higher total fat – raises risk.
Researchers studied 253 men with diverticulitis and determined that replacing one serving of red meat with a serving of poultry or fish reduces the risk of diverticulitis by 20%. (Yin Cao et al., 2018)
The study’s limitations are that the meat intake was recorded in men only, the intake was self-reported, and the amount consumed at each eating episode was not recorded.
It may be a helpful substitution for anyone at risk for diverticulitis.
Turkey is a lean alternative to other low-sodium meats, especially if the skin is removed and cooked fresh.
Turkey is also high in the amino acid arginine.
Arginine can help keep arteries open and relaxed as a precursor to nitric oxide. (Patrick J. Skerrett, 2012)
Allergies
Meat allergies can happen at any age. A turkey allergy is possible and may be associated with allergies to other types of poultry and red meat. Symptoms can include: (American College of Allergy, Asthma & Immunology. 2019)

For individuals looking to increase their antioxidant, fiber, and vitamin intake, can adding pomegranates to their diet help?
Pomegranates
Pomegranates can amplify various dishes, from breakfasts to sides to dinners, with their balanced blend of mild sweetness, tartness, and crunch from their seeds.
Health Benefits
The fruit has been found to be a healthy source of vitamins, fiber, and antioxidants. A medium-sized fruit contains:

Individuals need to eat more fiber for optimal gut health. Can adding avocado to their diet help improve the gut microbe diversity?
Avocado Gut Support
A diverse gut microbiome is beneficial to overall health. According to a recent study, eating one avocado a day can help maintain the gut microbes healthy, diverse, and balanced. (Sharon V. Thompson, et al., 2021) The researchers observed positive changes in gut bacteria and increased bacterial diversity in individuals who consumed an avocado every day for 12 weeks. (Susanne M Henning, et al., 2019)
Gut Diversity
The gut microbiome refers to the microorganisms living in the intestines. There are around 100 trillion microorganisms, including bacteria, viruses, fungi, and more, exist in the gastrointestinal tract. (Ana M. Valdes, et al., 2018) Having a diverse microbiome means that the body has a range of different organisms that offer various health benefits. Not having enough bacterial diversity has been linked to: (Ana M. Valdes, et al., 2018)
Arthritis
Obesity
Type 1 diabetes
Type 2 diabetes
Inflammatory bowel disease
Celiac disease
Arterial stiffness
Atopic eczema
Why Avocados?
The Institute of Medicine recommends a daily fiber intake ranging from 19 grams to 38 grams per day, depending on various factors like age. (Diane Quagliani, Patricia Felt-Gunderson. 2016)
Including foods like avocados in a healthy diet can help meet daily fiber requirements.
Fruit fiber like pectin, has been shown to promote a healthy gut microbiome as well. (Beukema M, et al., 2020)
Researchers suggest this could be because of pectin’s positive effect on beneficial probiotics.(Nadja Larsen, et al., 2018)
Although further research is needed fiber is believed to help protect the lining of the colon by increasing the bulk and weight of stool and expediting elimination.
Fiber also adds bulk to an individual’s diet and slows the speed of digestion, which makes the body feel fuller longer.
Improved Gut
Individuals can support a healthy microbiota by making small adjustments in their diet, including:
Eating a variety of fruits and vegetables with the skin, as this is where a majority of the nutrition is.
Fermented foods like yogurt, kombucha, sauerkraut, kimchi, and kefir.
Limiting consumption of processed foods, sugar, and artificial sweeteners.
If there are more avocados that can be eaten before they overripen, they can be frozen.
Peel and slice them first, then place them in freezer bags to have year-round.
They are rich in healthy fat, however, in moderation, they are not likely to contribute to weight gain.
Individuals can work toward having a diverse gut microbiome by paying attention to the foods they eat. Specific foods and dietary patterns can influence the different types of bacterial diversity which can support health.

Tomatoes are low-calorie and nutrient-dense, what health benefits can individuals gain from their consumption?
Tomato Benefits
All varieties of tomatoes offer nutrients, including potassium and vitamin C, making them part of a balanced diet.
Raw tomatoes contain vitamin C, which brightens skin and fights inflammation.
Cooking tomatoes releases more antioxidants which are vital in small quantities such as lycopene, for maintaining heart health and preventing certain cancers.
Other benefits contribute to heart, prostate, and cognitive/brain health.
Various tomato recipes and products can offer a balance of nutrients. Variety is key and this applies to all fruits and vegetables. Try them raw, cooked, and steamed, as the different methods can offer different benefits.
Cooked and Raw Tomatoes
Tomatoes are low in calories and rich in nutrients. A raw, medium-sized tomato contains roughly 22 calories and less than 1 gram of fat. It is low sodium and low glycemic, with just 6 milligrams of sodium and 3 grams of sugar. They are an excellent source of hydration as a raw tomato contains about half a cup of water.
Tomatoes contain several essential vitamins and minerals that support the immune system and the bones and blood.
Antioxidants help combat free radicals and unstable molecules that damage the body’s cells. (Edward J. Collins, et al., 2022)
Antioxidants like lycopene, lutein, and zeaxanthin, are better absorbed with cooked tomatoes.
Raw tomatoes contain small amounts of vitamins A and K, fluoride, folate, and beta-carotene.
Heart Health
Tomatoes provide a healthy serving of potassium.
Potassium and sodium are both vital for heart function.
Potassium is essential for relaxing the blood vessels.
One medium tomato contains around the same amount as a banana.
The heart needs these electrolytes to contract and expand.
Most individuals with high blood pressure can benefit from high potassium, fiber, and lycopene levels.
Studies have linked lycopene to lower heart disease risk and mortality. (Bo Song, et al., 2017)
Exercise Recovery
Electrolytes are essential for basic cell function.
Potassium, sodium, magnesium, and fluoride can help decrease muscle soreness and exercise fatigue after physical activity or workouts.
The anti-inflammatory properties come from the vitamin C.
Eating tomatoes before or after physical activity can help replenish magnesium which is essential for muscle contraction. (Edward J. Collins, et al., 2022)
Protection Against Dementia
Potassium provides power to the heart and has a role in body nerve function.
One recent study found that individuals who consumed more potassium and less sodium had improved cognitive function. (Xiaona Na, et al., 2022)
Another study analyzed how carotenoids/antioxidants that affect the color of vegetables affect long-term brain health.
Researchers found that individuals with increased blood levels of lutein and zeaxanthin, which are both present in cooked tomatoes had a lower rate of dementia. (May A. Beydoun, et al., 2022)
Lutein and zeaxanthin are also known for protecting eye health as the body ages.
Help Prevent Prostate Cancer
Cooking tomatoes compromises the vitamin C content, but increases the availability of several antioxidants that can protect against cancer growth.
Especially for men, lycopene is beneficial to help reduce prostate-related issues.
Studies have found that men who eat tomatoes, including raw, sauce, and on pizza have a lower risk of developing prostate cancer due to the total amount of lycopene absorbed, which is optimized in cooked tomatoes. (Joe L. Rowles 3rd, et al., 2018)
Lycopene and other plant pigments/carotenoids are believed to protect against cancer because of their antioxidant properties. (Edward J. Collins, et al., 2022)
Lycopene and other antioxidants in tomatoes can also benefit male fertility by improving sperm count and sperm motility. (Yu Yamamoto, et al., 2017)
Balance Blood Sugar
Tomatoes can help manage blood sugar in individuals with diabetes.
They have fiber that helps regulate blood sugar and bowel movements.
Fiber naturally slows digestion to keep the body fuller and longer and does not negatively impact blood sugar levels.
