Chronic low-grade inflammation is a root driver of cardiovascular disease, type 2 diabetes, and other chronic conditions. Dietary fat choices have a measurable and direct effect on inflammatory status — making this one of the most clinically relevant dimensions of fat intake.
The ketogenic diet shifts the body's primary fuel source from glucose to fat-derived ketone bodies. Understanding the metabolic mechanics of ketosis, which fats matter, and what the clinical evidence shows provides a clearer picture than most popular accounts offer.
Using the wrong oil for a cooking method wastes money, degrades flavor, and can produce harmful compounds. Matching oil to method — based on smoke point, stability, and flavor — is a simple skill that improves every dish you cook.
Ghee and butter start from the same ingredient — cream — but the process of making ghee removes water, milk proteins, and most lactose, producing a fat with different properties and a devoted following in Ayurvedic and ancestral diet communities. Here is what the science shows.
Fish is the most concentrated dietary source of EPA and DHA omega-3 fatty acids, but it is not the only one. For people who avoid fish — whether by choice or preference — understanding the differences between omega-3 types and their non-fish sources is essential for meeting nutritional needs.
Vitamins A, D, E, and K are called fat-soluble because they dissolve in fat rather than water. This means the amount of fat you eat with these vitamins directly determines how well your body absorbs them — a fact that makes low-fat diets a potential risk for certain deficiencies.
Gram for gram, the saturated fat in cheddar and the saturated fat in butter are close to identical. Fed to people in controlled trials, they produce measurably different LDL cholesterol. The explanation is the food matrix, and it is the most misused idea in the 2026 fat debate.
Few oils have generated as much controversy as coconut oil. Praised by some as a metabolism-boosting superfood and condemned by others as a cardiovascular risk, the truth sits somewhere in the middle — and the science is more nuanced than the headlines suggest.
Current guidelines recommend 20 to 35 percent of calories from fat for most adults. Within that range, the type of fat matters more than the exact quantity.
The FDA's 2018 ban on partially hydrogenated oils removed the primary source of industrial trans fats from the US food supply. But naturally occurring trans fats persist, and labeling rules allow trace amounts to be hidden.
Nuts and seeds are among the most nutrient-dense sources of healthy fats, but they vary significantly in fatty acid composition. Here is how the most common options compare.
Dietary fat is the raw material for sex hormones, stress hormones, and fat-soluble vitamins. Inadequate fat intake disrupts hormonal health in ways that affect energy, reproduction, and metabolism.
