What would lower yours?

Your LDL, then the changes you'd make. Each one falls toward your goal at the size its own trials measured.

Typed your panel already? The panel check works out your LDL from the other three numbers.

Your goal
Tap the changes you'd make

5% of 2,000 calories is about 11 g of saturated fat a day, about 1.5 tablespoons of butter (USDA FoodData Central 173410: 7.3 g in a tablespoon).

Your LDL, each change on its own

Psyllium, 10 g a day10 g of psyllium husk a day−1310 to 15 mg/dL
The fat swap5% of calories from saturated fat to vegetable oils and nuts−1110 to 12 mg/dL
The portfolio diet28.6% of your LDL: soy, nuts, oats and a sterol spread together for a month−39mg/dL
Medicine your doctor might prescribeA moderate statin lowers LDL 30 to 49%, a high-intensity one 50% or more30 to 50%for scale

Trials tested these one at a time. Together they usually add up to less than the sum, and nobody has measured how much less.

Your gap to under 100 is 38 mg/dL. On its own, the portfolio diet would reach it at its trial's average.

In the same one-month trial of 46 adults, the portfolio diet lowered LDL 28.6%, a starter statin 30.9% and the control diet 8% (Jenkins 2003). It included a plant sterol spread.

Plant sterol pills and red yeast rice aren't on the list. The 2026 guideline recommends against cholesterol supplements, and in a 28-day trial neither beat a sugar pill.

What your result means

  1. One or two bars reach your goal: start with those, keep them up every day, and retest at the same lab in 6 to 12 weeks.
  2. Even the portfolio bar falls short: food alone probably won't close your gap, and that's a medicine conversation with your doctor. Keep the food changes either way.
  3. Judge it by the retest: an LDL has to fall about 19% before the drop is probably real, since two tests swing that much with nothing changed.

How it works

Each change shows its trial's average with its range: psyllium about 13 mg/dL off LDL at 10 g a day (28 trials), oat or barley beta-glucan about 7 at 3 g (58 trials, the FDA heart claim dose), and the fat swap 1.9 to 2.4 mg/dL for every 1% of calories moved from saturated fat to vegetable oils, 1.4 to 1.8 to olive oil and 1.0 to 1.5 to carbs (Mensink, 69 trials). One percent of 2,000 calories is about 2.2 g of fat.

Weight loss lowers triglycerides about 4.0 mg/dL per kilogram (about 1.8 per pound), and LDL about 8 mg/dL across 6 to 12 month trials. Cutting sugar lowered triglycerides 6 to 13 and LDL 2 to 7. Two drinks a day less lowers triglycerides 2.5 to 8.9 and HDL by 3.3 to 4.7. At least 120 minutes a week of aerobic exercise raised HDL about 2.5.

The changes were tested one at a time and are never added up here. The medicine row is there for scale and is never a choice: your doctor decides that.
