General educational context on eating patterns, frequency of consumption and how foods can fit into an everyday diet.
Protein has the most consistent evidence for increasing fullness in controlled studies. Fiber can help, especially when it adds volume, viscosity or intact food structure, but not every fiber behaves the same way. Fat can slow gastric emptying and improve satisfaction, yet it supplies 9 calories per gram and is not automatically more filling per calorie.
Potatoes do not have a unique ability to create body fat. Overall energy balance matters, and preparation dramatically changes the calories in a serving: boiled potato is about 87 calories per 100 g, while a USDA fast-food french-fry reference is about 312 calories and 14.7 g fat per 100 g.
Sourdough fermentation can change several factors related to digestion: it reduces phytate, can lower some fructans/FODMAPs and partially breaks down proteins through grain and microbial enzymes. But “more digestible” is not a universal outcome. Reductions depend on the process, and human trials for digestive symptoms are inconsistent. Ordinary wheat sourdough still contains gluten and is not safe for celiac disease.
Seaweed has no single iodine value. One commercial analysis found 29–46 mcg/g in dried nori, 94–185 mcg/g in wakame, and 241–4,921 mcg/g in kombu. Species, location, growth stage, season, and processing all matter; some brown kelps can exceed the U.S. adult upper limit with less than a gram.
Dried spirulina is highly concentrated in protein: the USDA reference contains 57.5 g per 100 g and reviews often report roughly 50–70% dry weight. A 7 g serving, however, provides only about 4 g protein; reaching 20 g would require about 35 g of the reference powder.
Dried spirulina can contribute iron: the USDA reference contains 28.5 mg per 100 g, about 2 mg in 7 g. Its B12 story is very different. Chemical studies show inactive pseudovitamin B12 predominates, so spirulina is not a reliable source for preventing B12 deficiency.
Cocoa powder does contain caffeine. The USDA unsweetened natural cocoa reference has 230 mg per 100 g, about 12 mg in a 5.4 g tablespoon. A USDA alkalized cocoa entry is much lower, illustrating how widely products can vary. Theobromine, not caffeine, is cocoa's dominant methylxanthine.
Prunes concentrate nutrients and sugars as fresh plums lose water. Per 100 g they provide about 240 calories, 38 g of sugars and 7.1 g of fiber. A 30-g serving—roughly four to five prunes depending on size—has about 72 calories, 11 g of sugars and 2.1 g of fiber. Their effect on bowel function is not just about fiber; prunes also contain sorbitol and other fruit compounds.
A large egg contains roughly 185–200 mg of dietary cholesterol, almost all in the yolk; the white contains essentially none. Dietary cholesterol can affect LDL, but the milligrams in an egg do not translate directly into the number on a blood test because the liver regulates cholesterol metabolism and people respond differently. Current American Heart Association guidance places more emphasis on the overall dietary pattern and saturated fat than on dietary cholesterol alone; its egg-specific advisory says healthy people can include up to one whole egg a day.
Dietary cholesterol is cholesterol in animal-derived foods and is usually measured in milligrams. Blood cholesterol is carried in lipoproteins such as LDL and HDL and is measured on a lipid panel. Eating 200 mg of cholesterol does not add 200 mg directly to your blood: some is absorbed, while the liver adjusts cholesterol production and handling. For most people, overall diet—especially saturated fat—is a more important LDL target than chasing dietary cholesterol alone, although individual responses differ.
The easiest way to raise fiber is to change several parts of the day rather than depend on one food. A cup of beans or lentils may provide roughly 12–16 g, a whole fruit 3–6 g, an ounce of nuts 2–4 g and whole grains several grams more. The U.S. Daily Value is 28 g; increase gradually if your current intake is much lower.
Fiber is beneficial, but doubling intake overnight can feel very different from increasing it gradually. More fermentable carbohydrate reaches the colon, microbes produce more gas, and water-holding fibers increase intestinal volume at the same time.
