Answer:
Science and autopsies have reached a point in the modern world where poisons are generally detectable.
The best poisons are ones that break down into elements that occur naturally: succinylcholine(SUX) and potassium chloride. SUX causes asphyxiation and paralysis, however it is a very painful death. Potassium chloride causes severe heart arrhythmias and mimics a heart attack.
These break down to elements natural in the body and would easily be overlooked: succinic acid and choline for SUX, potassium and chloride of course for potassium chloride which is common in heart attack victims due to muscle damage. However both need to be injected and leave an injection site, this may be pesky if your victim does not take any injected medicine or drugs. While these are the least detectable they don't meet the criteria of being ingestable.
Aconite is another great one. It leaves Aconitum alkaloids, but these can only be detected by a gas chromatography/mass spectrometry. Death usually results from paralysis of the respiratory system or cardiac arrest. What is useful about this poison is it can be absorbed through the skin or consumed and only takes 2mg of pure aconite or one gram of the plant to kill. This method is fairly undetectable as long as there is no cause for an in-depth autopsy and it can be ingested.
Depending on your victims history, there are other ways to poison them and make it look accidental, for example if your victim loves blowfish, you could poison them with tetrodotoxin which naturally occurs but is generally removed by a skilled cook in the cooking process.
